Sun damage is an often overlooked danger of outdoor pursuits. Along with sunburn and dehydration, powerful rays can have a damaging effect on your eyes, especially if you're spending long days in the wilderness hiking, camping, or trail running.

That's where Tifosi's latest range of sunglasses comes in. Its new Shumo sunglasses feature shatterproof polycarbonate lenses, designed to protect your eyes from debris, wind, and powerful rays in the wilderness.

They're encased in the brand's Thrive frames, which are made from plant-based materials derived from castor bean oil. Their oversized, traditional shield-style design aims to cover your eyes from all angles, guarding you from harmful rays at all times of the day.

The Shumo glasses also weigh just 1oz (29g), so won't weigh you down as you speed through the trails or take on a tough hike in the sunshine.

“Shumo was designed for those who want performance-level coverage in a frame that doesn’t feel out of place outside of training or competition," says Tifosi owner Joe Earley.

"Its oversized lens provides the protection athletes need, while the frame remains versatile enough for everyday wear.”

The Tifosi Shumo glasses are now available with blue, gold, and black frames on the Tifosi website for $39.95 (£40).

Adidas SP0095 sunglasses: first impressions 

The Adidas Sport SP0095 sunglasses won't turn any heads if you're a cyclist, because everyone will be too busy looking at your bib shorts to notice, but if you're a trail runner, you're probably going to feel a little out of place wearing these. That said, we've found some things to like about these sunglasses for trail running.

The wraparound design that's loved by cyclists and apres ski bros does provide your face and eyes with more protection than other designs, even if it looks like a pair of safety glasses from the lab. However, this particular design seems to sit really high up, covering more of your forehead than is typical, and meaning your downward view is totally clear. That would actually be cool if they were polarized glasses, because it would mean you would be able to see your phone or GPS watch without removing your glasses, but they're not, so we're not sure it's intentional.

We got them out on the trail for some fast-paced adventures this spring and we have to admit that they are really comfortable and light, and most importantly they don't slip or bounce no matter how much you do. Despite that non-slip design, they didn't give us a headache or pinch anywhere.

They have ventilation slots at the temples to reduce fogging, and the arms are made with flexible materials that should be more durable. They also come with a hefty protective case which should prolong their lifespan.

Inside the case is a cloth for cleaning them, which works a charm, and an extra pair of clear frames, so in theory, you should be able to swap out the lenses for overcast days where you just want eye protection (and for cycling). Sadly, we couldn't figure out how to remove the lenses, and there are no instructions for doing so.

These are among the pricier sunglasses we've tested, but if you're dead set on a pair of wraparounds, we think you can probably find a pair that looks better, if you care about such things.

Adidas Sport SP0095 sunglasses: in the field 

It's taken me quite a few months to get round to testing these sunglasses, mostly because the UK experienced a winter of so-called "atomic gloom" and I just didn't need sunglasses, and partly because they're not really my style. Finally, however, spring arrived and I could put it off no longer, so I've worn these out on a couple of trail runs to see how they hold up.

Here’s how they performed:

Comfort and staying power

These shades are really comfortable on, and in the past I've found that comfort in sunglasses can mean you sacrifice staying power, but here that is not the case. They are extremely light and I can wear them for several hours without noticing them, and I don't experience any pinching on my nose, headaches or pain around my ears.

That said, they only come in one size and according to various retailers, that size is extra large so it seems to me that they won't work for everyone's face. They might always be comfortable but I can see them slipping down on smaller faces.

On my head and face, which as far as I know isn't unusually big or small, they just don't move, no matter how fast I'm running, if I break a sweat or when I'm wearing sunscreen.

Performance and durability

When it comes to sunglasses for running, I really just want a pair that protects my eyes and doesn't budge. This pair seems to fulfill both of those requirements, and I like the smoke tinted lenses which aren't too light or dark for Scottish conditions. They're not polarized, and that's fine for me since I wear goggles for skiing and I'm not going out on the water in them, and it means I can check my phone and my Coros Pace 3 watch without shoving them up on my head, which is great.

The wraparound design provides good coverage, but because there's only a frame across the top, my peripheral vision isn't obstructed, which is good. Strangely, they sit really high up on my face and quite far away from my face at the bottom. This means that they sit about half an inch above the top of my eyebrows but don't cover my cheeks at all. The result is that when I look down, my eyes aren't protected at all. This hasn't mattered on my adventures, but if I were out in a high glare situation like snow, I think quite a lot of UV rays would be seeping in under these glasses. It also means that you can't pull a running cap down low, but maybe Adidas is banking on you being a bro who wears your cap backwards?

They come with an extra pair of clear lenses, which would be great if you wanted to wear these for cycling, but for the life of me, I can't figure out how to swap the lenses out, and there are no instructions anywhere online. I did eventually just pull the lenses down and they unclipped from the frame, but I couldn't figure out how to extract them from the nose pads so I gave up. This feature does mean that if you require prescription lenses, you could use them with these glasses, but you might have to ask your optician to swap them for you.

The frames and arms are flexible, not brittle, which in my experience can mean they're most durable, but they feel like a fragile pair of glasses and not a pair I'd shove in my pocket. Fortunately, they come with a hard case which is really protective, but also really bulky so I wouldn't bring these on a longer trail run as they'd take up too much room in my vest.

Style and value

I don't like sporty, mirrored wraparound shades on my face or anyone else's (unless you're riding in the Tour de France) so I'm already predisposed to not love how these look, but in my opinion, the odd fit of these looks especially weird.

On the surface of things, you get a fair bit for your money when you factor in the case and extra lenses, but they are expensive, and the design is unusual enough that unless it really happens to work for your face, I think your money would be better off spent elsewhere.

Sunglasses are an often overlooked accessory for outdoor exploration, but they shouldn't be. Your eyes are vulnerable to the sun all year round, and overexposure can cause long-lasting damage, especially in exposed backcountry areas.

The best sunglasses protect your peepers from sun damage, provide a crystal clear view of your surroundings, and look cool in the process.

These two new Revo models aim to tick all the boxes - providing a sleek, protective experience in the wilderness. The limited-edition Moab and Himalaya glasses feature 360° protection from the sun with durable, protective lenses and side covers that block out unwanted rays.

The Himalaya glasses were designed with chilly frozen environments in mind, while the Moab glasses were built to handle the heat in rugged desert landscapes.

Revo crafted the new pairs in collaboration with professional climber and wildlife filmmaker Renan Ozturk.

Over a 20-year career, the Turkish-American daredevil has completed and documented multiple breath-taking climbs. He's best known for summiting the hair-raising Shark's Fin route on the Himalayan Meru Peak with fellow film-maker and climbing legend Jimmy Chin.

Ozturk has represented Revo as an ambassador for more than a decade and worked in tandem with the brand to create the latest pairs - dubbed the Revo x Reo collection after his initials.

"I’ve relied on Revo’s Traverse sunglasses throughout my expeditions, and now, I’m thrilled to channel my experiences and passion into designing two styles that truly capture the essence of extreme exploration," said Ozturk.

"From the rugged Moab desert to the majestic Himalayan Mountains, these glasses are designed to protect your vision while elevating your style."

The Himalaya glasses feature brown leather side shields and a H2O heritage blue glass lens, designed to stop sun damage in snowy, high-altitude environments.

Built to protect against the harsh rays of rugged desert landscapes, the Moab glasses pair a smoky green glass lens with leather side shields and a silver frame. Both are now available for $299 (£239) on the Revo website.

Longer, brighter days might not quite be here yet, but they're on the horizon and to help get you ready for spring skiing and summer hiking, Smith Optics has gone deep into the archives.

The Rocky Mountain eyewear brand has revamped and relaunched its iconic Ultralite sunglasses for 2025. First dropped back in 1987, the wraparound shades were inspired by the ski goggles that first put Smith on the map.

Featuring a cylindrical shield lens, these oversized retro sunglasses are designed to give your eyes and face extra protection on bright days, while ventilation holes help keep things from getting too steamy when the temperatures start to rise.

The 1980s weren't exactly known for sustainability, but the new-and-improved Ultralites have been updated with a bio-based frame that's lighter and more durable than the original, though we still recommend you use the throwback fleece pouch provided when you're not wearing them to avoid scratching the lenses.

They're also equipped with the brand's proprietary ChromaPop lens technology which is said to improve contrast and boost color to make those mountain views even more dazzling.

Sweat and sunscreen can make for smudged lenses as you keep pushing your shades back up your nose, but the Ultralites have comfortable no-slip nose pads that react to moisture and stay put. All said and done, these shades are giving us major retro vibes and that's definitely the intention.

"The retro ski goggle inspired design pairs well with high-top sneakers, a fresh mullet, and a good Beastie Boys track playing on the Walkman," says the brand.

The Ultralites are available now in Matte Malachite, High Voltage, 80s Night, Matte Black and Matte Tortoise for $175.00 at SmithOptics.com

SunGod Miras: first impressions 

Unlike some other styles from SunGod, which are built for specific activities, these sunglasses are intended for everyday use. But as we've come to expected from the the Verbier-based brand, they're built for a certain degree of performance and actually make a decent pair of hiking sunglasses.

What sets the Miras apart from other styles is that they're built for people with small faces. Other than that, they're made from the same materials as the SunGod Tempests (except these frames are made using 100% recycled plastic, which is a huge upgrade for us) but have less performance-specific details.

The most noteworthy aspect of these shades when you put them in just how light they are. At a mere 20 grams, you can easily forget they're on your face and on a long hike, that's no bad thing. The frames are flexible and screw-free, so even though they feel a little flimsy, they can hold up to a little bit of pressure and a few drops. That said, what would really help is a hard case in place of the pouch that's included.

These sunglasses are 100% customizable, so you can pick between standard, polarized or SunGod's 8KO polarized lenses in a variety of colors and choose your preferred frame color while you're at it.

These shades are straightforward, comfortable and stylish for small faces, and a decent price for SunGods too. They're a good choice for travel or easy day hikes where you don't need anything too technical, like wraparound shades, as long as you don't try to pick up the pace  –  then they'll definitely slide down your nose.

SunGod Miras: in the field

It's always a bit of a risk agreeing to test sunglasses when you live in Scotland. Will I actually get any sun this summer? Answer: no, but fortunately I travel a lot, so I've been testing these in the Grape frame/Gold lens customization during several trips to the Alps this summer.

Here’s how they performed:

Sizing, comfort and staying power

I don't necessarily think of myself as having a small face, but photos taken with friends suggest otherwise and these glasses confirm it. They're just about perfect on me. I love the oversized sunglasses look for the city, but not for hiking so these make a better choice, and if you have an even smaller face than me then I think you'll be really happy with the sizing.

They are extremely comfortable to wear all day, and that includes when I was out in hot, sunny weather following the UTMB runners around the 106-mile course in Chamonix as well as several long hikes in the Swiss Alps. Basically, I don't even notice I'm wearing them and there's no pinching or pressure on my nose or ears.

Sometimes, that can mean that shades will slide down but these stay in place well for hiking, even with sunscreen on my face. That said, staying power has a lot to do with nose shape so I can't promise the same for you. As a test, I did try trail running with them in Chamonix and that did not work out at all, but they're not designed for running.

The only slightly funny thing that's worth noting is that they're so small that when I wore them with a trucker-style cap, if I pushed them up on my head they actually popped off, so you'll need to wear a lighter cap with these.

Visibility, cleaning and maintenance

As long as I've given these a good wipe with the pouch included, the lenses are super clear and I'm doing my best to not smudge or scratch them. 

I went with polarized lenses and they're great in really bright, high-glare situations, such as next to a lake, and a little dark in low-light situations such as the type we get here in Scotland, so I'll probably be saving these for my travels. Remember that the lenses are totally customizable so you can choose whatever you need. The frame is noticeable around the edges, but it's not huge so it doesn't block peripheral vision.

I own the SunGod Tempests, which I really love, but I find it quite hard to get those lenses completely clean, while these are better in that regard. I love having the cleaning pouch, but I'd also love a plastic case (my Tempests have recently lost a leg due to lack of hard case).

Durability and style

These sunglasses do feel a bit flimsy and while mine popped off the top of my head a few times and landed on the ground without so much of a scratch, I'm aware that I'll need to get a hard case soon before they come to grief. The flexible frames really do help with durability, and it's unlikely they'd break by being dropped but they need a bit more protection when they're inside my backpack.

I must say even though I'm usually a fan of an oversized frame, I do really like the slightly retro vibe of these sunnies, and am happy to keep them on when I get off the trail and back into town.

SunGod Miras: the bottom line

If you've been looking for a pair of SunGods that are suitable for hiking but not ultra-technical and come at a decent price, these are a great choice, though of course you also need a smaller face to wear them. They're featherlight, comfortable and protect your eyes and are made with lots of recycled content so you can feel happier about your choice. For something a little more technical, check out the SunGod Tempests.

If you like getting out on the trails, the best running sunglasses should be one of your most important items of kit – and this is the case year-round, not just in the summer. Experts advise that anyone who spends time outdoors, whether running, hiking or cycling, needs to take care to protect their eyes from damaging ultra violet (UV) light emitted by the sun.

Sharon Copeland, an optician at Feel Good Contacts, explains that there are three types of UV rays that the sun emits: UVA, UVB and UVC.

She says: “UVC rays are the most damaging but they are absorbed by the Earth’s atmosphere before they reach us and are not a direct threat.

“Meanwhile, UVA and UVB rays can have serious long and short-term effects on the eyes and our vision.”

Why runners need sunglasses for UV protection

There are different health risks caused by exposure to UV light including: 

• UV light can speed up the process of age-related macular degeneration (AMD). This happens as we age but exposure to UV light can speed up the condition where the retina becomes damaged, resulting in central vision loss.
• Cataracts take the form of clouds that form on the lens of the eyes. These cause your vision to be “clouded”. There is a greater risk of cataracts due to exposure to UVB rays. Cataracts require surgery for removal.
• Pterygium can be the result of exposure to UV light and takes the form of a benign growth on the conjunctiva of your eye.
• Photokeratitis is usually caused by UVB light reflecting off snow and can lead to sunburning of the eye. This mostly takes the form of blurred vision or temporary sight loss.

The best way to protect your eyes is to stay away from bright sunlight but this is not always possible, especially if you are a runner. Also, sunlight does have health some benefits, such as being a natural source of Vitamin D and boosting feel-good hormones. This means, you should wear good quality sunglasses.

Sunglasses for runners: what to look for

This most important factor when choosing sunglasses is to ensure they will protect your eyes from UV radiation. Ideally, this means buying sunglasses with a UV 400 protection. 

UV 400 ensures the dark lenses filter out almost 100% of harmful ultraviolet light rays. The more technical explanation is the UV 400 blocks wavelengths up to 400 nanometers, including UVA and UVB rays. 

When looking at different types of sunglasses, check they are labelled with a CE or UV 400 mark, which confirms they conform with the EU standards of eye protection.

Copeland reveals other factors to consider when purchasing sunglasses for running. She says: “The sunglasses with the most protection from the sun’s rays are often those with a darker lens.

“Wrap-around style frames and frames that sit close to the face offer a fuller coverage of your eyes from different angles around the lenses. 

“Polarized sunglasses provide further protection against glare and halos from reflected rays if you are near water or snow.” 

It’s important to consider the size of the fames and lenses, too. The larger the lenses, the greater the protection for the eyes and also the eyelids and the skin around the eyes. Choosing frames with wider arms (also caled "temples") aids protection, too.

There will be many runners who also require prescription lenses. You can choose to wear contact lenses and then off-the-peg sunglasses, or purchase sunglasses with prescription lenses. Always check with the dispensing optician that the lenses include adequate UV filters.

As an extra precaution, if you wear everyday prescription glasses, ensure they have UV filters as standard in the lenses.

What lenses should runners choose for sunglasses?

There are all kinds of lenses with different colors, tints and coatings. While darker lenses can provide good protection from UV rays, on cloudier days you might not be able to see so well. This is why there are different colors and shades of lenses. 

Dr Elizabeth Hawkes, who is an oculoplastic surgeon, said: “The type of lenses that you choose for your sunglasses depends on what you will be using them for. 

“For example, tinted lenses are good for certain sports, because they reduce the light intensity and cut the glare, which helps to reduce eye strain. 

“Another consideration is whether or not the lenses are polarized. Polarized lenses reduce the glare from horizontal surfaces such as water, the road and snow. They can be more expensive but they are ideal if you’re doing lots of driving or spending time by water.”

Categories of lenses

Regardless of the color of the lens, whether dark brown, grey or red, it's vital you assess the the category number of lenses. The category of the lens for sunglasses equates to a percentage of the VLT (Visible Light Transmission), which details how much light the lens lets through.

• Category 0: 80 to 100% VLT
• Category 1: 46 to 79% VLT
• Category 2: 18 to 45% VLT
• Category 3: 8 to 17% VLT
• Category 4: 3 to 8% VLT. 

As a guide, for sunny weather and especially when spending time outdoors such as when running, you should look for “category 3” lenses as a minimum.

Lens coatings

When buying good quality sunglasses, including prescription sunglasses, you might be able to choose to pay for extra coatings. These may include mirrored coatings or anti-scratch coatings and mirrored coatings, although the best way to look after your sun spectacles is to keep them in a case or pouch when not in use.  

The best frames for running sunglasses

There are many different shapes and styles of sunglasses, so choosing the right look will be dependent runners trying on the sunglasses. For example, some frames shapes suit different shapes of faces. 

While the look of the sunglasses will be important, fit is even more vital.  As a runner, you will not want the glasses to keep on slipping down your face.

Many companies make sunglasses to fit different sized heads. You will want the sunglasses to stay put on your nose and also your ears so you should check the size of the frame and your head shape.

Check the the frames and lenses provide good coverage of the eye and skin around the eye for the best protection. Choose wider arms at the side of sunglasses for more protection from the sun. 

The sunglasses need to stay in place while you run. One way to check this is to put on the sunglasses and then move your head down, back and side to side. If the specs move at all, you know it is likely thy will slip around in your face when you run. 

Rubber or silicone-tipped arms and comfort nose pieces can be helpful for making sure the frame stays in place on your face. 

Regardless of the shape of the frame, whether wraparound or more traditional, you should look for lightweight sunglasses. Plastic frames and lenses made of polycarbonate, rather than glass, keep the weight to a minimum. 

Look for hinges that are likely to be more durable. Hinges that open inwards and also outwards are more likely to be long lasting, especially if you are constantly taking them on and off. 

The verdict on sunglasses for running

Eye experts recommend that when running it is important to have protection from the sun's harmful UV rays – and all year round. The best solution is a pair of comfortable and high quality of sunglasses. Adding a sun hat for running will improve your protection from the sun.

ENGO Eyewear has updated its popular ENGO 2 augmented reality sports sunglasses with adaptive lens technology that can deal with changing light conditions and still provide field-of-view live stats. 

Like their predecessor, these new ENGO 2 Photochromic sunglasses provide a heads-up display that gives runners and cyclists a clear view of their workout straight in their line of vision so they don’t have to keep looking down at their smart watch or a fitness tracking device strapped to their handlebars. But now the lenses react to light changes, so that you can train from dawn to dusk.

The ENGO 2 Photochromic sunglasses seamlessly adjust to ambient light, automatically transitioning from a clear tint in low light to a darker protective tint in bright sunlight. Users can now train with access to their critical performance data regardless of the light intensity without compromising their natural movement, cycling position or running form.

Like the ENGO 2, the ENGO 2 Photochromic weighs 36g and combines a lightweight, sleek design with a long-lasting 12-hour battery life. The new photochromic lenses add to the versatility of the eyewear while maintaining its signature sharp display. ENGO Eyewear’s touchless gesture control means you can toggle between custom display fields, by waving your hand in front of the lens.

The ENGO 2 Photochromic is available in two sizes to fit a variety of face shapes and sizes and is also available in a frameless design.  

“The response to the original ENGO 2 has been phenomenal,” said Marc Vernet, ENGO brand manager. “Runners and cyclists of all levels are consistently telling us how ENGO is impacting the precision of their training, helping them maximize intensity and improve overall performance during their long runs and rides. ENGO 2 Photochromic enhances this experience and enables sports enthusiasts to leverage the power of ENGO eyewear during any session, regardless of the time of day or weather conditions and is designed to be an athlete’s go-to companion for every run and ride so they can focus on achieving their training goals.”

ENGO 2 Photochromic sunglasses are available now from the ENGO website, priced at $350 (US) / £301 (UK).

Have you ever thought of your sunglasses as a weapon in the psychological war against your racing competitors?

No. Us neither, but Nike apparently has. And the result is two new downright weird pairs of shades – the Nike Athena and Nike Zeus – which are designed to be worn before and after competing with the intention of unsettling opponents.

The Zeus pair look like something a bird-themed supervillain might wear in an R-rated DC movie, but even stranger are the Athena glasses, which are strikingly asymmetrical – if you catch yourself in reflection you might think you’ve wandered into a hall of distorting mirrors by mistake. 

Nike say the glasses are “intended to be worn before and after competition as a form of psychological armor — whether to protect or project”. 

“While we were initially focused on designing something for competition, the insight we heard from our athletes is the need for a mental edge or advantage, before and after competing,” says John Hoke, Nike’s Chief Innovation Officer. “Their ability to get totally into the zone, to be completely focused and undistracted, is so, so critical for these athletes.”

Apparently, according to the press release, “The styles usher in a new level of digital artistry in service of athletes, advancing Nike’s aesthetic horizons while offering contrasting visions of sport’s future.”

The Nike Athena pair is described as “a celebration of asymmetry and expression, with mirroring that wraps from lens to temple… Screwless, ultrasonic bonds and stainless-steel temples (or arms) contribute to a lightweight frame, which positions the lens further from the face to help eliminate the ‘lash crash’ sometimes caused by shallower sunglasses.” 

Meanwhile, the Nike Zeus pair is, “inspired by traditional acupressure points and the look of ‘speed’ – an enduring Nike fixation… Mask-like and worn close to the face, Nike Zeus builds on the innovative ventilation of the Nike Windshield Elite 360, with intricate, fluted perforations increasing airflow to help eliminate heat pockets around the nose and cheekbones while directing heat away from the eyes.”

Both styles incorporate recycled materials; at least 40% of Nike Athena’s total weight and 20% of Nike Zeus.

So just what is the line between fashion victim and sartorial psyche assassin? Well, if you want to find out be prepared to put your hand deep in your pocket. The Nike Athena cost $250 (US) / £219.99 (UK) and the Nike Zeus are $500 (US) / £409.99 (UK). Both designs will be available globally on Nike digital platforms from today (July 24).

Adidas Dunamis: first impressions

These super-sized Adidas Dunamis sport sunglasses are out to make a statement, and some down-to-Earth trail-running types might feel somewhat self-conscious wearing them on casual runs and races. I definitely did.

But once you realize how ridiculously lightweight these Dunamis are, and get a taste of the level of functionality they offer, it’s easier to put such reservations to one side.

Designed for use by all kinds of runners (on road, trail and track), as well as cyclists (again, across all forms of riding, from mountain biking to gravel and road riding) and other sporty types (golfers, tennis players) these brand new sunnies have been released in time to coincide with the start of the Summer Olympic Games in Paris.

Tying in with that things-that-originated-in-Greece theme, the name Dunamis comes from an Ancient Greek philosophical concept about releasing inner power, potential and ability (Adidas certainly aren’t shy when it comes to making grandiose statements with their products).

Adidas Dunamis: design and materials

With a range of lens and arm color options available, the Dunamis have been made in collaboration with Italian eyewear maestros Marcolin. The frameless design features a single-piece, wide, wraparound, visor-style lens that offers superb surround vision, completely unimpeded by obstructions. 

These category 3 sunnies have a Visible Light Transvmission (VLT) rating of 14% to 15% (it varies very slightly according to the lens color you opt for). Although it’s not polarized, the thermoformed lens is engineered to enhance color perception and reduce glare. The lens has also been treated with a hydrophobic and oleophobic coating, which means water droplets run straight off and it is more resistant to scratch damage and accumulation of dust. The bottom of the lens features a unique spoiler, which flares out slightly to sit more securely on your face and (maybe…) to make you a touch more streamlined. 

The arms have a large vent window by each temple, to help prevent the lens from steaming up when you’re puffing hard, and also feature a contoured, rubbery grip pattern, which runs from the vent to your ear. The bridge sits right on the wearer’s nose, but adjustable rubber buffers keep the glasses both secure and comfortable.

Adidas Dunamis: in the field

Adidas Dunamis are intended not just for running, but also bike riding and other sports such as golf. The latter pursuit is not for me, but I have been wearing these impressive (albeit eyebrow-raisingly expensive) shades while trail running, mountain biking and road cycling this summer, in the light and bright conditions of the solar-powered Southwest. 

The first thing to note is that the Dunamis are incredibly lightweight – barely bothering the needle on the scales, just gently pushing it to a smidgen under 1oz (28g). Combined with this, the lens shading is subtle (but effective) and the absence of a frame means you do actually half-forget you’re wearing these sunnies, until you realize you’re not squinting and the flies are bouncing off a near-invisible forcefield in front of your eyes (especially whilst riding).

The arms feature a textured temple-gripping pattern that keeps the glasses very securely in place, even when you’re running (or riding) on rough terrain, and negotiating constant obstacles. On test, I don’t recall the Dunamis moving as much as a millimeter, despite me jumping and leaping around across rocks on my morning beach run (where the tide often forces me off the shingle and on to the boulders).

Further enhancing this secure hold, the bridge grip is snug without feeling pinchy or uncomfortable, even when worn for an extended periods of time. There are ventilation slots in the arms too, which I found pretty effective at preventing the lens from steaming up.

The inclusion of a flared spoiler at the bottom of the lens is a really interesting feature.

It seems a bit (OK, a lot) of a stretch to claim that this improves performance through enhanced aerodynamics (unless you’re eyeing a sub-10-second 100m sprint, or donning a teardrop helmet to do time-trial style cycling), but it does mean the glasses sit comfortably on your cheeks. However, I did notice a very small amount of distortion at the extreme lower edge of the lens when I was running, which I think is caused by this design (it wasn’t enough to cause a problem).

Overall, these are excellent all-sport sunglasses, and they come with a very good semi-rigid storage case and cleaning cloth… and also an eye-watering price tag.

Tifosi Swank Single Lens Sunglasses: first impressions 

We really rate these sunglasses for hiking, cycling, light running and water sports as well as hanging out around town at the beach due to their all-day comfort and robustness, not to mention very reasonable pricing.

The classic design isn't too showy and should suit most faces (a larger size is available), while we found the fit to be really secure, even when sweat and sunscreen were involved. That's helped by the hydrophilic nose pads, which increase grip as you sweat, so there's no chance that you'll have to stop midway through a scrambling session to push them back up your nose.

They are really lightweight and it's easy to forget you're wearing them, thanks in part to hair-friendly hinges that don't snag on your bangs, and we've dropped them enough times to declare the polycarbonate lenses to be pretty sturdy, and so far scratch-free.

Most importantly, with full protection against UVA and UVB rays, these shades are good for bright days when you're doing most things outdoors, be it hiking, jogging, paddling or lounging. They only come with a microfiber cleaning pouch, no hard case, but for the price you'll have a little money left over to get one.

Tifosi Swank Single Lens Sunglasses: in the field

Saying yes to testing a pair of sunglasses when you live in Scotland is always a gamble. Will you ever see the sun? Fortunately for me, I've had a couple of hiking trips to Corsica and Gran Canaria recently where I got to see that great big ball of fire in the sky and test these out.

Here’s how they performed:

Comfort and staying power

As I mentioned, I've been able to test these out on a couple of trips over the last couple of months, and I kept forgetting to write them up. That's mostly due to the fact that they're really comfortable, so I'd forget I was wearing them and therefore meant to be testing them. 

The description says these are sized for small and medium-sized heads, with an XL version available for a slightly higher price. I think my head is medium and they're a perfect fit, with no discomfort on my ears even when I wear them all day. One problem I sometimes have with glasses is that my eyelashes rub up against the lenses, which is insanely annoying, but no such issue here.

Even though the classic look doesn't appear at first glance to be super technical, I'm surprised at how well these stay in place even when I've been jogging or have greasy sunscreen on my sweaty face. I don't think I've had to stop and push them up once.

Visibility and cleaning

The lenses shield my eyes from a bright sun, even when I've been at the beach looking out at the water, and because they're not polarized, I can also stop to check AllTrails on my phone without having to take them off. They might be a little dark for some cyclists and the thicker frame is noticeable as compared to something like my SunGods Ultras, but no more so than any regular pair of shades.

Some of my more expensive sunglasses are difficult to clean once smudged, but the microfiber pouch works well on these so I haven't found myself constantly wiping them.

Durability and style

We all know that more expensive sunglasses tend to break or disappear within minutes while a cheaper pair will be with you for life. These are on the quite affordable side and even though I've dropped them several times, they're holding up nicely. I'm also pretty sure I've absent-mindedly wiped them on my shirt, a big no-no in the world of sunglasses, but the lens don't have a scratch on them.

However, my main issue is that they don't come with a hard case, and when I'm traveling they usually go in one of the small pockets of my backpack, which then gets shoved in an overhead locker or under the seat in front of me on a plane, and I think there's a good chance they'll end up broken eventually if I don't get myself a case.

As for style, the best way I can describe these is classic. There's nothing about the design that wouldn't suit most faces or go out of style any time soon, and they've quickly become my everyday sunglasses as a result.

Tifosi Swank Single Lens Sunglasses: the bottom line

These sunglasses are versatile enough to be worn across different sports and in town, but offer excellent grip and staying power if you do decide to up the ante while wearing them. We found them to be lightweight and comfortable and we love the price tag, though if you find they don't suit your face it's worth checking out the Tifosi Swick which share many of the same features as these.

When you spend a lot of time outdoors and moving fast, you probably pull out all the stops to protect your ankles from sprains by wearing the best hiking boots and to defend your skin against frostbite in cold conditions by using the hiking layering system. There’s another part of your body that can be vulnerable when it comes to spending time in sunny, windy, snowy and cold conditions, however, and that’s your eyes.

From snow blindness to allergies, your eyes can end up dry, red or even damaged by your time spent on the trails if you’re not careful, but it’s also quite easy – and important – to make sure things don’t get that far. Read on our five best eye care tips for hikers and runners to protect your peepers outdoors.

1. Get some good eye protection

Rain or shine, in snowy or dry conditions, your first line of defense against hazards like the sun, grit, wind, branches and winged insects is to protect your eyes using the shield of sunglasses, or ski goggles for winter sports.

Sunglasses for hiking and trail running need to protect your eyes against both UVA and UVB rays for starters. If you’re going to be hiking near ice, snow or water, you'll need to take the glare factor into account and use polarized sunglasses like the Oakley Clifdens.

Even if it’s not sunny, it’s a good idea to wear sunglasses and it’s helpful to have a darker lens on your sunglasses or giggles for bright conditions and a lighter lens for low light conditions. Wraparound shades like the SunGod Ultras do provide better protection, even if you don’t love how they look.

If you already wear glasses, invest in prescription sunglasses so you’re never tempted to take them off, and read our guide to how to clean sunglasses for the same reason.

2. Wear a brimmed hat

Sunglasses block out a lot of those UVA and UVB rays, but when the sun is high, they can still sneak in over the top, and that’s why it’s a good idea to wear a brimmed hiking hat when you’re outdoors. These types of hats protect your entire face, and though they seem like they’re best for summer days, a lot of them like the Arc’Teryx Paltz cap are really low profile, which means you can even wear them under helmets.

3. Carry eye drops

Whether or not you suffer from red eyes or allergies, a small bottle of eye drops is a great addition to your hiking first aid kit. It means you can wash out any intruders like grit or insects more easily, and if your eyes do start to feel dry or strained, you can stop every so often and hydrate them.

4. Check your sunscreen

If your eyes tend to get really stingy on more aerobic adventures, it’s a good idea to check your sunscreen. If you're using a chemical sunscreen, it might be getting in your eyes and be the source of the problem. Look instead for a mineral sunscreen that uses zinc oxide and titanium dioxide and your eyes might be much happier.

5. Stay hydrated

Finally, dehydration might be causing your eye discomfort, particularly when you’re working up a sweat in warm or very arid conditions. Staying hydrated on the trail is crucial for lots of reasons, and not least is that your eyes might feel better. Make sure you carry at least one water bottle, or a hydration bladder, when you go hiking or running and take regular sips. 

• What does VLT mean in sunglasses?

With snow on the way, it’s time to think about all the fun parts of winter – making sure your ski pants still fit and checking your ice axe for rust – as well as some of the more important safety aspects, like getting avalanche safety training and knowing how to use your avalanche beacon. There are other risks of winter sports, including high altitude hiking, that make the headlines less frequently than avalanches but that you’ll want to be equally aware of, and one such threat is snow blindness. 

A 2018 literature review on snow blindness describes the condition as a major health problem affecting travelers, and it’s a frequent issue for high altitude adventurers like mountaineers, ice climbers and even those who seek out the ski slopes come winter. In this article, we explain how to spot snow blindness symptoms, what to do if your eyes have been affected and how to prevent it when you’re recreating in snowy and ice conditions. 

What is snow blindness?

Snow blindness is medically considered to be a type of Photokeratitis, which the American Academy of Ophthalmology (AAO) explains is essentially sunburn of the eye. This painful eye condition occurs when your eye is exposed to UV rays. The condition affects your cornea – the clear outer layer at the front of your eye – and conjunctiva, which is the clear tissue covering the whites (sclera) of your eye.

You can suffer from Photokeratitis as the result of watching a solar eclipse or recreating outdoors without proper eye protection, or even from using a tanning bed. Snow blindness, however, is a specific type of Photokeratitis that occurs when your eye is burned as a result of UV rays reflecting off snow and ice. Snow blindness may also refer to freezing and drying of the cornea’s surface, due to extremely cold and dry air. Consequently, activities like ice climbing, skiing and mountaineering are activities commonly associated with snow blindness.

What are the symptoms of snow blindness?

A bit like when you come home after an afternoon hike in the summer only to realize your arms and chest are a suspicious shade of pink, snow blindness can sneak up on you without you realizing it. According to the University of Utah Health, symptoms to look out for include:

• Eye pain
• Burning or gritty sensation in the eye
• Sensitivity to light,
• Blurry vision
• Seeing halos around light sources
• Swelling of the eyes
• Headache

These symptoms may not develop until several hours after exposure, and the longer the exposure, the worse your symptoms are likely to be.

How to treat snow blindness

If you've come back from a long day in the snow and you start experiencing some of the above symptoms, according to the AAO, snow blindness usually goes away on its own, and treatment is focused on reducing the uncomfortable symptoms as your eyes heal. If you suspect snow blindness, you should consult a medical provider, and they will most likely recommend some of the following procedures:

• Remove contact lenses
• Stay out of the sun and in a dark environment
• Place a cold washcloth over your eyes
• Use lubricating eye drops
• Avoid rubbing your eyes

A medical provider may also recommend pain relievers or antibiotics for your eyes.

How to avoid snow blindness

It's pretty obvious that you want to avoid getting sunburn on your eyes, and as you might expect, the best treatment for snow blindness is to prevent it in the first place. This doesn’t mean you can’t head out for those snowy adventures on bluebird days by any means, but you should never head out without proper eye protection.

For wintery exploits, make sure you always wear polarized sunglasses like the Oakley Cliffdens which have a chemical coating that helps protect your eyes against glare by blocking out horizontal rays of light while letting vertical rays in. You can improve the protection by choosing wraparound styles like the SunGod Velans and wearing a peaked hat or helmet.

If you’re going to be moving fast downhill on skis or your snowboard, you’re definitely going to need to wear ski goggles, and not sunglasses, which completely seal out the cold wind as well as blocking UV rays and further reduce your risk.

Finally, remember that sunburn of any part of your body can occur even when it’s cloudy, and is more likely to occur at high altitude where there’s less UV-blocking atmosphere for those rays to burn through, so don’t be fooled into leaving the shades in your backpack. For low light or variable conditions, make sure you have a lighter lens you can use – a decent pair of ski goggles will allow you to switch out your lenses to suit the conditions.

Sungod Tokas: first impressions

SunGod is best known for its sports sunglasses, including models designed specifically for cycling and running, but the Tokas (available direct from SunGod) are a new design made for in between your outdoor adventures. That said, they're still super resilient, and can easily handle some hiking and running as well.

At first glance, the square-framed Tokas look similar to the SunGod Tempests, but comparing the two the Tokas are noticeably lighter (just 25g) with a slimmer frame design. That's impressive considering the Tempests certainly aren't heavy.

The Tokas' frame is made from 100% recycled memory polymer, which will spring back into shape without snapping if bent – and they don't bend easily.

As with all SunGod shades, you can take your pick from various frame and lens colors, and pick either standard polycarbonate or tougher, clearer 8KO nylon for the lens material.

You can upgrade to polarized lenses for an extra fee (see our guide to polarized vs non-polarized sunglasses for a rundown of the differences). My review pair have polycarbonate lenses with polarization. All lenses feature triple-layer scratch-resistance and 100% UV protection.

SunGod also offers prescription lenses for prescriptions ranging from +8.00 to –7.00. These are available in standard and thin options (people with strong prescriptions are encouraged to opt for the thinner option), and with or without polarization

A hard case is available as an optional extra, which is a little surprising at this price point but the Tokas are supplied with a soft pouch to protect against scuffs and scratches and it reduces waste if you already have a case that you're happy with from a previous pair of shades and don't need a replacement.

Sungod Tokas: on the trails

The Tokas are so comfortable and versatile, I ended up wearing them for pretty much everything this summer.

Although designed mainly as lifestyle shades, I found the Tokas great for hiking and occasional running too. They don't provide the same wrap-around protection as the SunGod Ultras for long races and training sessions, but if you're looking for a single pair of sunglasses for the streets, the trails and everything in between, the Tokas are a good middle ground – light and secure, but not overtly sporty.

The Tokas are unisex sunglasses designed for wearers with medium or large heads, and I'd agree with that assessment; I have a relatively large head, and they fit well, providing good coverage from brow to cheekbone.

Despite their light weight, they don't look at all 'cheap' and feel super secure even during runs. Their ear pieces and nose bridge are well shaped to keep them firmly in place without any uncomfortable pressure points, even when things get warm and sweaty. The screwless hinges are tough too, folding with a pleasing click.

Visibility is excellent, even with the standard polycarbonate lenses, with great clarity. The polarizing coating really cuts down on glare, and will come in particularly handy if you're spending any time near water, whether that's fishing, boating, or paddleboarding.

People with smaller or narrower heads might be better served by the SunGod Classics, which are medium rather than medium/large, but for anyone else the Tokas are an excellent option that'll avoid the need to carry multiple pairs of shades on vacation or multi-day adventures.

Dynafit Ultra Evo sunglasses: first impressions

These Dynafit Ultra Evo sunglasses are bold-looking shades for self-confident runners – as with brightly colored football boots, if you’re going to wear running sunglasses that are as attention-grabbing as these are, then you need to be either a pretty good runner, or not give a damn what people think.

I’m more of the latter than the former, but I did feel more than a little self-conscious at first while running on the more trafficked trails in my area while wearing these sunnies.

But whatever you think of the aesthetics, there’s no denying that these are excellent running glasses. They’re fantastically light, and the minimalist, top-only frame is completely invisible when they’re on your face. The frames are also very grippy – keeping the sunnies firmly in place – without being uncomfortable.

They come with a big zip-shut rigid case to keep them safe, and a little pouch made from a material you can use to clean the lenses (see also: How to clean sunglasses the right way).

Dynafit Ultra Evo sunglasses: on the trails

So, at first I must admit that I tended to stick to the more remote paths and quiet coastal tracks while I was wearing and trail-testing these big, brash Dynafit Ultra Evo sunglasses. The look and style of these shades is a bit out-there for me, and I don’t have the running talent or the right head/face to pull them off. (In case I was under any delusions about the latter, my family repeatedly pointed it out to me.)

But, increasingly, I found them so good on seriously sunny days (with a VLT of 14%-16% they’re pretty dark) that I didn’t really care all that much about who I saw, or who saw me, while I was out running in them. At 31g / 1oz they virtually float on your face, and the lack of any visible frame only adds to this illusion.

The wraparound lenses facilitate a very broad range of sight. They also provide comprehensive protection from glare and stop flying insects and debris from getting anywhere near your eyes. The super-grippy tips on the arms and nose bridge mean there is no bounce, even when running on extremely rugged and technical terrain.

There are vents at the top and bottom of the excellent lenses, which allow air in to cool your face when you’re climbing and prevent fogging. And the lenses themselves supply superb high contrast vision, so you can see every bump and trip hazard on the trail.

SunGod, maker of some of the best hiking sunglasses, is now offering prescription lenses for its whole range of everyday shades – including the new SunGod Tokas, which launched last month.

Prescription lenses are available for the Renegades, Zephyrs, Sierras, Tempests, Tokas and Classics, with prescriptions ranging from +8.00 to –7.00. Prescription shades 

First, design your sunglasses by choosing a frame style, them picking the color of the frame, lenses, and logos on the arms. Next, choose the new 'prescription lenses' option, and pick either standard or thin, with or without polarization.

If you have a higher prescription, the thin option is the best choice to keep your shades light and comfortable. Choosing polarized lenses makes colors look bolder and brighter, reduces glare, and generally makes your eyes feel more relaxed. All lenses offer 100% UV protection and triple-layer scratch resistance, and are made with impact-resistant materials.

Finally, send SunGod your prescription, either straight away or using the link in your confirmation email later. You should receive your new shades within 10 days of sending it in.

Prescription sunglasses are available now from £90 per pair. See SunGod's website for more details and to start designing your own.

SunGod Velans: first impressions

A more technical pair of shades than the SunGod Sierras, the SunGod Velans (available direct from SunGod) are designed for a slightly wider face shape, and they provide protection from the side. More performance orientated than fashion focussed, they are among the best sunglasses for hiking and mountain activities. 

The Velans have 8KO spherical lenses in plastic, flexible frames. The frames come with a lifetime adventureproof guarantee, so any breakages to them will be replaced free of charge. You can also choose from just top frames, full frames or a system that lets you swap between both.

There’s a wide range of lens choices available with a full spectrum of visible light transmissions (VLT) ratings, so you can customize these sunglasses to suit your needs. The price is very much dictated by the lens and style you end up choosing, so different prices for ostensibly the same model are possible. While the weight of the glasses is low, the price tag is fairly heavy.

SunGod Velans: on the trails

I tested these sunglasses with category 3 polarized lenses, but other lenses are available in category 2, 3 or photochromic in a variety of tints. Other colors are also available – in fact, this product can be customized to pretty much whichever color you like, making a pair of sunglasses that are very much your own.

On test I found that the wraparound style of the SunGod Velans provided great visibility and excellent protection from glare, especially in snow and ice. That said, the sizing is quite large and may overwhelm narrower faces. 

Being able to customize to your exact tastes is always a nice touch, as is the frame guarantee. I’ve had these sunglasses for over a year and they haven’t broken under regular use, although one arm has become a bit wobblier than the other. It would be nice to have a case included, however, and that addition might save SunGod money on their guarantee.

Ive worn these sunglasses up alpine peaks and down country lanes. If you choose your lenses wisely (I was wearing Cat 3 lenses, at the very lowest end of its VLT range) they can cover you for summer snow as well as countryside hikes.

Scott Vector Sunglasses: first impressions

Among the best sunglasses for hiking and mountain adventures, Scott's Vector sunglasses are a comfortable, close-fitting pair of shades, with Fusion frames and no-slip soft nose pads. The frame has some flex in it but feels very sturdy and has rubber-coated tips at the end of the arms to help keep the sunglasses in place. 

The lenses are large for this style of sunglasses, but they don’t have quite as much height as a lens in, say a classic round frame. The Vectors are available with a range of lens options, all with the Scott Precision Optics quality label. 

The Red Chrome lenses are category 3, and have a VLT (visible light transmission) rating of 10%, which makes them a little on the dark side for some activities, such as driving on cloudy days. 

There are narrow slits at the top and side of each lens to help improve airflow and stop the glasses from steaming up. They have 100% UV protection, but they are not polarized. 

Scott Vector Sunglasses: on the trails

These sunglasses came with me on my Winter Mountain Leader Training in the Cairngorms. Unsurprisingly, it was not particularly sunny in the Highlands of Scotland in January, but it was still quite bright, and the course required us to spend a lot of time looking at blank snow slopes close up. 

These sunglasses provided just the protection I needed from the midday light passing through the clouds and reflecting off the snow. No need to squint, a good snug fit and very good clarity. 

The demisting vents really helped too when I was wearing them underneath helmet straps, in situations where taking them off and on again to clear my vision would have been an absolute faff.

• How Advnture tests products

SunGod, maker of some of the best trail running sunglasses, has launched a new pair of everyday shades for the summer months. The new SunGod Tokas have a light, square-shaped frame to wear in between your outdoor adventures, but share plenty of DNA with sportier models like the Sierras, Tempests, and Ultras to make them light, tough, and comfortable.

Each pair of Tokas has a 100% recycled memory polymer frame, which will flex without snapping and spring back to its original shape, and are certified carbon neutral.

You can choose either standard lenses, or SunGod's own 8KO material, which makes them lighter, clearer, and tougher. All lenses feature triple-layer scratch-resistance and 100% UV protection.

The Tokas are available to buy now direct from SunGod starting at $90/£70, with an array of frame and lens colors to choose from, and can be customized for no extra cost.

Tifosi Swick sunglasses: first impressions

Tifosi Swick sunglasses are instantly impressive, with a simple but classy design that belies their very reasonable price tag. Multiple lens and frame color options and combinations are available, so you can customize these sunglasses to suit your style and tastes.

Comfortable to wear, the flexible and robust nylon Grilamid TR90 frame has a seemingly basic design, but the arms and nose pads keep these lightweight sunnies firmly in place no matter what you’re doing, which earns them a place in our guide to the best sunglasses available at the moment for hiking and climbing.

The nose pads are hydrophilic (so the grip they supply increases the more you sweat), and the glide coating on the arms is made to reduce bounce. The integrated hinge is also designed to avoid catching and pulling hair.

The polycarbonate lenses are scratch-resistant and shatterproof, and rated as category 3, so they’re ideal for protecting your eyes while you’re exploring terrain from sea level up to low alpine areas.

Tifosi’s Swick sunglasses also come with a soft, microfiber cleaning bag / pouch, but no hard case.

Tifosi Swick sunglasses: on the trails

As my wife never tires of telling me, I have the kind of face / head that looks stupid in most sunglasses (and hats, apparently), but she concedes that the Tifosi Swicks are so stylish that even I can’t make them look bad. This is such high praise that I should perhaps leave it there and give them five stars. 

But we really should talk a little bit about the performance of these sunnies, which is almost as impressive as their looks. Since I’m actually allowed out in public in them, I have enjoyed extensively testing the Swicks while hiking, biking and running on trails around the currently sun-splattered Southwest of England. 

I experienced no visual distortion through the optically decentered lenses, and despite their relaxed and casual lifestyle look, I’ve been comfortable wearing them while negotiating some pretty technical trails, both on a bike and whilst running. 

The nose and temple grips keep them securely in place, no matter how lumpy the landscape I’ve been running and riding over became, and for the most part they’ve been pretty comfortable to wear for reasonably long periods of time – the hydrophilic nose grips seem to pinch slightly after while, but this can be relieved by lifting the glasses momentarily.

They offer no side protection from glare, which might be an issue in some circumstances, but this means there’s a good amount of ventilation, and I haven’t experienced any major fogging problems.

The lenses are Cat 3, and although the VLT is unspecified, they strike a good balance between remaining functional for everyday activities like driving, and providing enough protection for outdoor pursuits (unless you’re really high up in the mountains, when some Cat 4 glasses would be better).

Bollé Adventurer sunglasses: first impressions

These premium-priced Bollé Adventurer sunnies are, as the name suggests, designed specifically for adventure pursuits. High performers, they are among the best sunglasses around for hill-hiking and mountaineering, but can be a tad dark for driving and low-level wear in anything but the brightest conditions.

Designed with the frame shape of classic glacier sunglasses, they come with either photochromic Phantom lenses or Solace4, Bollé’s new mineral glass lens designed specifically for the mountains (Category 4). There are three choices of color for the mineral lens frames (black, white or dark green) but only black for photochromic version. The lenses have great optic clarity and anti-fog features, as well as supplying 100% UV protection. 

The frames of these sunglasses incorporate built-in side shields and a bridge piece. Unlike other available models on the market, these side shields do not fold down or come off. 

The Thermogrip nosepieces are adjustable to fit the shape of your face, however, and they are hydrophilic, which in theory makes them grippier in wet and sweaty conditions. Thermogrip is also used on the tips for a more comfortable fit. 

A cord leash is provided, with holes in the frame, at the end of the arms, to attach it to, and they come with a handy protective case and a microfiber pouch.

Bollé Adventurer sunglasses: on the trails

These Bollé Adventurers came up north with me to England’s Lake District and the Cairngorms in Scotland and quickly proved themselves ideal sunglasses for hiking.

They are a lightweight pair of glasses, but still feel sturdily built. Having side shields that don't need to be folded was a good for use in the mountains, and I found the side coverage around the eyes to be decent.

The lenses are large and provide good visibility. Having photochromic lenses allows you to use one pair of sunglasses for all situations. Not being able to remove the side shields does mean you can’t convert to a more “normal” look for post-adventure social wear, but they are fantastic as an all-round pair of mountain sunglasses. Just make sure you know how to clean sunglasses the right way so you don’t damage them.

Like several other models I've tested from different brands, the Bollé Adventurers left a gap around the bridge of my nose, allowing light through. However, as someone with a small face, this was the best fit I'd had in the classic glacier glasses style. I also really appreciated the coloration in the lenses; the rosy tint made everything look better – especially in snowy conditions.

BLOC Eyewear Pilot Sunglasses: first impressions

The versatility and general functionality of the BLOC Eyewear Pilot Sunglasses earned them a spot in our roundup of the best sunglasses for hiking and mountaineering, but they do have their limitations.

Found at a fairly pocket-friendly price – comparatively speaking – these sunnies are metal-framed, aviator-style glasses, about the size of a pair of average reading spectacles. This is a less sporty look, which suits social wear as well as active use on trails and hillsides.

Available in category two and category three versions, and in a wide range of colors, the BLOC Pilots can be worn on sea-level walks, hill hiking adventures and in the peaks up to a point, but they are not suitable for high-altitude mountaineering. 

There is no case included, but they do come with a cloth pouch that offers some protection from accidental scratching.

BLOC Eyewear Pilot Sunglasses: on the trails

I trialled a category three version of the BLOC Eyewear Pilot Sunglasses over several weeks of walking and winter mountaineering on the west coast of Scotland. On test I found they felt lightweight and minimalist on my face, and the metal frames are very smooth, making it easy to get them on and off.

Although the frame materials do not seem to have much give in them at all, the nose pads are adjustable, allowing some flexibility in fit, and are also hypoallergenic. Having a small point of contact helps to reduce sweat, and I could feel plenty of airflow getting to my face as I hiked and scrambled, which meant the glasses didn’t steam up.

The impact-resistant XTR Karbon8 optical class one lenses provide good clarity and protection, and I found them to be pretty effective at blocking glare, but, because of their style, they are quite small and there is no side coverage to block out excessive light in very bright situations (learn more about why you need to protect your eyes on the trails in our sunglasses for hiking feature).

The only quirk is that at certain angles of light, other people can sometimes see your eyes through the lens – or, weirder for them, one of your eyes is visible, while the other remains hidden behind the reflective surface.

The three-star rating is due to durability. Within a few months, one of the arms had broken off at the hinge. Although the metal itself is durable, the hinges are a weak point – only minor squishing in a rucksack caused the arm to snap off at its join to the lens frame, just next to the hinge.

SunGod Sierras: first impressions

Specifically designed for the needs of the modern adventurer, SunGod's Sierras sunglasses are among the best sunglasses available for hikers and peak scramblers, although there’s no protection for your eyes at the sides.

Sierras sunglasses with less-expensive 4KO non-polarized lenses start at £70, with the 8KO polarized lenses being the premium, pricier offering. The 8KO lenses have fantastic clarity and depth of color. (For more information see: polarized vs non-polarized sunglasses: which do you need?)

The frames are very flexible and light. Pop-Lock hinges mean there are no screws to come loose. (Note: the adventureproof guarantee that SunGod are famous for only covers the frames.) The Sierras frames are good for small to medium size faces, so if you have a wider face you may want to consider the SunGod Velans instead. 

SunGod Sierras sunglasses: on the trails

The SunGod Sierras are a great all-rounder pair of sunglasses for someone with an active lifestyle, and I’ve been wearing them for pretty much everything, from climbing mountains to popping to the shops. 

They are a good, comfortable fit for a small face and the unobtrusive style doesn't look out of place when you’re off the trail. 

Although it is really excellent to be able to essentially build your own pair of sunglasses, they do feel a little on the expensive side for what you get. And at over £100, it would be nice to have a case included – even with the lifetime guarantee to protect them.

Oakley Clifden sunglasses: first impressions

Classic-style sunglasses, designed and made with mountaineering firmly in mind, Oakley Clifden sunnies are among the best sunglasses for high-level hiking and peak climbing. 

These are the only frame style in Oakley’s range that have the removable side shields required for high-altitude protection. That said, the Prizm Deep Water lenses are a Category 3 – although other lower VLT lenses are available, including Category 4, which is more suitable for high alpine adventures (although not recommended for driving).

The frame and lenses are lightweight, with some flex in the frame itself. The side shields are easy to take on and off and the wide bridge effectively reduces light access to the eyes.

The rubber-like material of the shields and nose pads help to make a secure but comfortable fit around the face. But you can’t help but have a little giggle that they’ve called this patented material Unobtainium, a nod to the Avatar movies. 

These sunglasses are available in a range of six color and lens combinations, with lenses designed to enhance the color, contrast and detail of whatever you’re looking at. 

The hard case and woven metal cord (with closed attachment points at the end of each arm) are great touches. Plus the possibility of a prescription lens will be very welcome for many users. 

Oakley Clifden sunglasses: on the trails

On test I found the Oakley Clifden sunnies to be a great-feeling pair of sunglasses – extremely comfortable, with good-sized lenses for top levels of visibility. 

The side shields are comprehensive and reliably protective in bright and glare-filled conditions, such as on mountainsides, but they are also removable, so you can take them out in situations where they feel like an overkill feature.

The frame is flexible but strong, too, although I'm a little surprised they are quite so expensive (you certainly pay for the Oakley name as well as the excellent performance levels).

However, in a similar way to the Vuarnet ICE Round sunglasses, I do find small spots of sunlight sneaking through at the bridge, around my nose. The Oakleys are closer to a good fit for me, but while I’m working on the assumption that this gap is occurring because of my face shape – and not because the glasses have a high bridge – it’s worth bearing in mind if you too have a smaller face.

Adidas SP0057 Sport Sunglasses: first impressions

It’s difficult to find one pair of sport sunglasses that do it all, but Adidas SP0057 Sport Sunglasses prove it’s not impossible. Whether you want to run, bike, ski tour or simply bust some style, the Adidas SP0057s check all the boxes — especially the style known as 02L, which is photochromatic with lenses that adjust to variations in light conditions. They’ll definitely be vying for a place in the next update of our best trail running sunglasses buying guide.

Marcolin, an international eyewear company founded in Italy, was specifically chosen by Adidas to design and be the official licensee of Adidas eyewear, because of their ability to access premium materials. And that quality is very apparent with all the Adidas eyewear I’ve tested.

The frame material provided by Marcolin is called TR90, a nylon and carbon fiber composite, which is ultra-lightweight, flexible and resistant to accidental impacts. The aeration system of the Adidas SP0057s sits right above the nose near the center of the brow line with nine holes to prevent fogging, and the adjustable nose pads and flexible temples with rubber on the interior make for personalized comfort and a grip that doesn’t give way.

I first tested a pair of Adidas SP0057s on a fall morning trail run in Sedona, Arizona, and the lightweight frame stayed put with no bounce. We started on a chilly morning, so I was wearing a headband and neck warmer, a combination that will often fog-up certain sunglasses. However, the aeration system of the SP0057s worked wonders, and I had no issue with fogging at all during my testing period.

The Adidas SP0057 02L is photochromatic, with lenses that adjust to variations in light conditions but for this test we used the SP0057 92Zs. We had some visibility issues with their violet, mirrored lenses in low-light canyons, but as soon as we popped back up into the sun they were ideal (see also: Polarized vs non-polarized sunglasses: which do you need?).

Once we headed out to mountain bike in the afternoon, the Adidas SP0057 92Zs were perfect for shielding the bright sun, and they stayed put as I bounced and rolled over red rocks. The lightweight and flexible frames sat on my face effortlessly so I was able to focus on the trail rather than adjusting the shades.

Vuarnet ICE Round sunglasses: first impressions

From the moment you open the box, these Vuarnet ICE Round sunnies feel like a premium product, and they certainly rank among the very best sunglasses out there for high-level hiking and mountaineering.

Like a classic watch, these sunglasses are clearly designed to last a long time and to be used year upon year as the only pair of sunglasses you’ll ever need in the snow or at altitude. (Obviously you wouldn’t go for a Cat 4 lens for everyday use, as they're too dark – our comprehensive guide to VLT levels explains the different VLT categories.)

The frames are made of high-strength bio nylon with adjustable sleeves that can be bent into place to fit your head. The sun protection is excellent: there are removable side shields that are easy to slide in and out. The bridge has an insert piece that can be taken out too, allowing the Vuarnet ICE Round sunglasses to be converted into a more everyday look for off the mountains.

The lenses are a natural mineral lens that provide the sharpest vision possible in extreme light conditions. They feel like a very strong material compared to other sunglasses I’ve tested. There is a choice of 11 color and lens combinations, including both Cat 3 and Cat 4 options. My test pair are Matt Black Eclipse.

They come in a stylish white leather protective case with attachment loop, which includes a microfiber cleaning cloth, and there’s a two-year warranty, too. 

Vuarnet ICE Round sunglasses: on the trails

These sunglasses feel expensive. They are noticeably heavier than any other pair I've tried, and the weight is all in the lenses. You know they mean serious business as soon as you put them on your face, and they can certainly perform at the highest level at the pointy end of mountain terrain. 

The Vuarnet ICE Round sunglasses are marketed as being sized medium. As someone with a smaller face, I found that the bendable area on the arms meant that they didn’t fall off when I leaned forwards – but only just.

On test I found that a tiny spot of daylight did sneak in through the frame, in the T-shaped indent at the top of the nose (and if you don’t know why this is a bad thing, read our feature on sunglasses for hiking: why you need to protect your eyes on the trails). Again, the pair I tested are designed for a medium fit.

Despite this slight annoyance, overall I was very impressed with the clarity and quality of these sunglasses, especially the mineral glass lenses.

• How Advnture tests products

It's easy to think that you don't need a pair of the best sunglasses for your hiking adventures during the colder months. However, while the levels of UV are lower in winter and early spring due to the tilt of the Earth, your eyes are still vulnerable, making decent shades essential.

On top of this, if you're someone who ventures above the snow line, the best sunglasses are absolutely vital. This is because pristine snow reflects UV light, virtually doubling the intensity that reaches your eyes. As UV rays can damage your eyelid, cornea, lens and retina and it's not damage that will ever heal, protecting your eyes is clearly important.

Besides, let's not forget, sunglasses also look cool! This guide features a mix of both Category 3 and Category 4 lenses. Cat 3 lenses have you covered for most of the places you'd venture in your hiking boots, while Cat 4 lenses – which aren't suitable for driving – are for extreme environments, such as desserts or high altitude.

We've tested these 10 excellent pairs on coastal trails and mountain ridges to bring you this expert guide. We rate the Scott Vector Sunglasses as the finest pair for their strong flexible frame and secure fit.

The quick list

This is the quick list, a snapshot of the best sunglasses available in 2026. To delve deeper into the features and qualities of each featured pair, see our more detailed reviews further down the page in this guide.

The best sunglasses 2026

The best sunglasses overall

Our expert tester Emily rated the Scott Vectors as the top pair of shades in our roundup, thanks to their supreme comfort. Meanwhile, the Fusion frame and no-slip soft nose pads give them a really secure, close fit. While the frame has at least some flex, Emily commented that it "feels very sturdy and has rubber-coated tips at the end of the arms to help keep the sunglasses in place". 

For the style, the lenses are admittedly large yet, compared to a traditional round frame, they're not as high. There are a range of lens options available and all come with the Scott Precision Optics quality label. The Cat 3, Red Chrome lenses Emily tested receive plenty of airflow, thanks to the narrow slits at the top and side of each lens. This stops them from fogging up during periods of exertion. As you'd expect, they boast full UV protection but it's worth bearing in mind that they're not polarized.

The best sunglasses for lightweight performance

Versatility is the order of the day when it comes to the SunGod Tempests. Our expert tester Julia reckons they're a great shout for the trails but also states that "they won’t look out of place worn at a sunny sidewalk cafe or at the beach either".

They boast a lightweight, comfortable fit that stays in places, negating the need to push them back up every 10 minutes on the trail. This is aided by a grippy nose pad. These design features are crucial for hiking shades, as it stops them falling off during sections of scrambling. On days when the sun is bright and brilliant, the 8KO lenses provide full protection.

Not only this, the Tempests are reasonably price, have resistance to scratches and they didn't fog up no matter how strenuous our activities. The frames are soft and flexible, while being made from recycled content that doesn't break easily. They come with a soft, microfiber pouch to carry and clean them. The lifetime warranty means you can expect to wear them for many years and you can also customize the lens and frames to suit your vibe.

The best sunglasses for customization

Intended for the modern adventurer and boasting a shape and style that suits the office, the commute and the beer garden, as well as mountain trails, the SunGod Sierras are great all-rounders. As we've come to expect from SunGod, there's plenty of customization options when it comes to frame color, lens type and polarization.

Our tester Emily found that the frames were "very flexible and light" during the test, while Pop-Lock hinges mean no screws waiting to come loose. There's the premium offering of the 8KO lenses, which give excellent clarity and color depth, while the 4KO non-polarized lenses come in a little cheaper.

The best sunglasses for mountaineering

Designed with mountaineering in mind, Oakley's Clifden sunglasses sport peformance alongside a classic style. Their mountaineering intent is underlined by the fact that these are the only frames in Oakley's arsenal that boast removable side shields, the sort needed for protection at altitude.

Our expert reviewer Emily tested the Prizm Deep Water Cat 3 lenses, though lower VLT lenses are also available, which take the Clifdens into the realms of Cat 4. The overal package is lightweight, with flexibility in the frames.

Emily reported that she "found that the rubber-like material of the shields and nose pads help to make a secure but comfortable fit around the face". It's quite funny that Oakley have named this material Unobtainium, just like in the Avatar film series. There are half a dozen color and lens configurations available, with various contrasts and detail levels available. For those who value prescription lenses, these are also on offer.

The best sunglasses for clarity

The Velans are designed for a wider face shape than SunGod's Sierras and boasts spherical 8KO flexible lenses with the brand's lifetime guarantee, which excludes theft, loss or scratches but breakages will be replaced free of charge. 

Our tester Emily felt that "the wraparound style provided great visibility, especially in the middle of the face". She tested the Cat 3 polarized lenses but there are Cat 2 or photochromic options too, which come in a variety of tints. As ever with SunGod, there are a range of customization options, so you can very much make these your own.

The price is very much dictated by the lens and style you choose, so different prices in the same model are possible.

The best Cat 4 sunglasses

"From the moment I opened the box, these Vuarnet ICE Round sunglasses felt premium" says our expert tester Emily. In the same way as a classic watch, these shades are obviously durable, designed for the long haul and intended for use year after year as the only pair of sunglasses you’ll ever need for your more extreme adventures. These feature Cat 4 lenses, which are unsuited to driving but ideal for high altitude.

High-strength bio nylon frames come with adjustable sleeves that can be shaped to fit your head. Our reviewer Emily stated that the sun protection was excellent and that the side shields were easy to pop on and off. 

The lenses provide excellent clarity, while feeling very strong in comparison to other shades in this roundup. There is a choice of 11 color and lens combinations including both Cat 3 and Cat 4 options. The sunglasses come with a two-year warranty.

The best photochromic sunglasses

The clue is in the name. The Bollé Adventurer sunglasses are intended for adventurous souls. They take inspiration, in terms of shape, from classic glacier glasses and come with a choice of photochromic Phantom lenses or Solace4, Bollé’s new mineral glass lens intended specifically for the mountains (Category 4). 

On test, our reviewer Emily found that "these lenses had great optic clarity and anti-fog", while they also boast 100% UV protection, as we'd expect. Unlike many of the mountaineering glasses in this guide, the side shields don't fold down and they can't be removed. There's adjustability in the Thermogrip nose pieces, which means you can tailor the fit to the shape of your face. Thermogrip is also used on the tips for that comfortable, secure fit.

The best sunglasses for versatility

With multiple lens and frame color options, Tifosi’s Swick sunglasses manage to be "both super stylish and completely unpretentious looking" according to our expert tester Pat. They manage to do this while also being hugely functional for use on the trails. On test, Pat found that they were perfectly comfortable, while the flexible and robust nylon Grilamid TR-90 Frame kept them very much in place no matter what activities he got up to. Whether hiking, biking or running, they were enjoyable to wear.

The grip the nose pads supply increases the more the wearer sweats, thanks to their hydrophilic qualities. Meanwhile, to reduce bounce, there's glide coating on the arms. The lenses are polycarbonate, scratch-resistant and shatterproof, with a Cat 3 rating. This makes them suitable for exploring from sea level up to low alpine regions. "Extremely durable, very versatile and super affordable, these sunnies are a great adventure companion for everyone except small-faced high-altitude mountaineers" says Pat.

The best budget Cat 4 sunglasses

Sometimes you don’t want to jump in at the deep end and buy an expensive or high-tech piece of kit. Maybe you’re just testing the water in an activity or can’t justify the high cost, even if the product might last you a lifetime. If that’s you, the very reasonably priced Quechua range of sunglasses may well be what you’re looking for. What’s better is that budget doesn’t necessarily mean cheap and nasty – we found that these sunglasses performed very well on test. 

The Quechua have all the basic features covered. We thought the wraparound frame is a close fit and, although the lenses are quite small, our vision wasn't impeded. The polycarbonate lenses block 100% UV light and are polarized. Although they are very shock resistant, they are also quite prone to scratches. This model is rated Category 4, with very dark lenses designed for exceptionally strong sunlight (high mountains), absorbing between 92% and 97% of visible light. If you’re not adventuring at this level and want a less dark lens, Decathlon’s Quechua range also has sunnies with Category 3 dark lenses designed for strong sunlight (sea and mountains), which absorb between 82% and 92% of visible light.

The frame is made of a bio-sourced polymer and is quite stiff, which could become uncomfortable with all-day use at the end of the arms and on the nose pads. Having an elasticated leash is a great addition, which is easy to take on and off as you wish. The sunglasses also have a two-year guarantee.

The best budget sunglasses for style

Metal-framed and in the aviator style, BLOC's Pilot shades are around the size of a pair of reading glasses and come at a decent price. They're undoubtedly less sporty looking than most on offer, so they make for a versatile pair that can be worn in the mountains and in the city. Lightweight and minimal, the frame doesn't have as much give as others in this guide. The hypoallergenic nose pads are adjustable, allowing for flexibility in terms of fit. This small point of contact helped to reduce sweat and our tester Emily found that there was plenty of air flow. 

This pair of BLOC Pilots are in Category 3, but other lenses available if you’d prefer Category 2. There is no case, but they do come with a cloth pouch that offers some protection from accidental scratching. Emily goes on to say that "the lenses are effective but quite small due to the style and there is no side coverage to block out excessive light". So, they're not really suited to the high mountains.

How to choose the best sunglasses

There are myriad lens options out there, so here are some important questions to ask yourself that will help you choose the best sunglasses for your adventure. 

What are sunglasses category ratings?

The most important factor when it comes to outdoor sunglasses is the type of lens they use, and specifically, how much visible light they let through. 

The amount of visible light transmission (VLT) is split into four bands: the imaginatively named Category 1, Category 2, Category 3 and Category 4. These are sometimes abbreviated to just Cat to be less of a mouthful. 

• Cat 1 sunglasses let in 46%-79% VLT so aren’t really that effective. You could wear them when it’s already overcast or just to look good. 

• Cat 2 sunglasses let in 18%-45% VLT and are good for normal sunny days, without snow or altitude being added to the mix. 

• Cat 3 sunglasses have 8%-17% VLT, so are ideal for use in the mountains – these are typically described as being good for sunny days at altitude without snow, or on overcast days at altitude with snow (you may still find them too dark at sea level on a standard day). 

• Cat 4 have 3%-8% VLT, which is exactly what you need when adventuring at high altitude or when exploring in the mountains at altitude where it is both sunny and snow-covered. Note: Cat 4 sunglasses are so dark that in some countries – including the UK – it’s illegal to wear them while driving. 

How should hiking sunglasses fit?

People often ignore this question when buying “normal life” sunglasses, just shopping by price or look, but it’s actually a rather important factor when you’re engaged in outdoor activities. 

You need a pair of sunglasses that fit your face size so that you don’t get loads of extra light coming in around the edges. Or even just be uncomfortable to wear for long periods of time or fall off easily. You’re probably going to be wearing these for eight hours a day, so make sure they’re a good fit. 

Most brands allow you to shop by face size, although some you have to guess a bit whether you’re small, medium or large. 

What extra features should I look for in hiking sunglasses?

There are a host of extra little features available in hiking and mountaineering sunglasses. Some will be really key for you, and others won’t matter to you at all. It’s very personal. 

For example, do the glasses come with a case to protect them, or a guarantee for when you sit on them? Do they have removable guards for extra light reduction at higher altitudes? Is the glass durable and scratch resistant? Can you attach a cord to keep them in place or maybe it even comes with a cord? 

Think about your ideal and regular uses for these sunglasses and try to find some special features that will make your life easier and turn these into your favorite sunglasses.

What to do with your old sunglasses

If your sunglasses aren't in good enough condition to donate or sell, you can send them to Bird for recycling, and receive a voucher for 20% off a new pair. Many high street opticians also accept glasses and sunglasses for recycling, so look out for a drop-off point or ask at the counter whether there's a program in place.

If the lenses are scratched, you may be able to have them replaced without buying entirely new sunglasses. Again, your local optician will be able to say whether it's possible for your particular frames.

Nike Wildhorse 8 trail running shoes: first impressions

The Nike Wildhorse 8 are trail running shoes built for long days out, when you want to prioritize comfort. They are easily one of the most comfortable trail running shoes around.

The plush feeling of these shoes is delivered by a React Foam midsole and roomy toe box, which makes them comfortable enough out-of-the-box for wearing around town, while a rock plate adds protection and responsive stability when the trail gets a little rough. With an 8mm drop, these shoes are likely to be coveted by heel strikers first and foremost, while any runner will benefit from the secure lacing system that locks your foot in place.

Not only are these shoes lightweight, they are outstandingly stylish, so you might end up keeping them for casual use instead of tearing them up on the trail (though they aren’t the most breathable when things heat up).

If you are hitting the trail in them, you’ll benefit from the grippy soles on slick terrain, but be aware that the uppers won’t provide as much protection for your feet against sharp rocks than more rugged technical trail shoes. Save these for long days on mellow trails.

Nike Wildhorse 8 trail running shoes: in the field

I haven’t run in a pair of Nikes for about 15 years now, and I’ve never tried any of the company's trail running shoes, so I was excited to find out what advances they’ve made in their running footwear when I was offered a pair to test out from SportsShoes.com. I’ve been wearing these shoes for about a month now on the trails in Scotland and love their out-of-the-box comfort so much that I ended up wearing them for travel and hiking on a recent trip to Spain.

Here’s how they performed:

Sizing and fit

These shoes fit true to size (I wear a UK 4 and tested a 4) and they have a roomy toe box that feels great for me. My feet are neither wide nor narrow, so I’m not sure if they’d feel too roomy for a narrow foot, but a sock-like tongue construction and secure lacing system means you can comfortably lace them up to stay put when you’re in motion, and it helps keep out gravel, too.

Comfort

Aside from the fact that these are a great-looking pair of shoes, the thing I love most about them is how comfortable they are. They feel like running in clouds and I went for 10k in them on the first day with not a hint of a hot spot. The sole is plush and bouncy, but there’s a decent degree of responsiveness in them too, plus they’re really light weight which makes them great for long runs. I’ve even tried them out on a few tarmac adventures and really like how they absorb the shock of the harder surface.

Breathability

Nike claims these shoes are breathable, and the uppers are certainly mesh, but I must say when I wore them on a warm weather hike in Spain, I actually did notice my feet getting sweatier than I’d like. I don’t notice this when I’m running, partly because Scotland has had an extra cold spring, but for everyday wear I wish they were a bit more breathable. I did recently get a good soak in them when running on a grassy surface in the rain, and I was pleased to see how quickly they dried out, so I think they're great for wet weather as long as it's not too cold out.

Grip and protection

The soles on these shoes have deep lugs. I put their grip to the test on the Penon in Spain, which is steep, slick limestone rock that rises straight up out of the sea. I’ve hiked it dozens of times over the last 30 years and I know it’s as slippery as a dry trail can be, and these shoes stood up better than any I’ve tried before.

SunGod Tempests sunglasses: first impressions

SunGod’s Tempests (available to buy direct from SunGod) are a high-performing pair of hiking sunglasses built for people who like to spend a lot of time on the trail, but they won’t look out of place worn at a sunny sidewalk cafe or at the beach either.

For hiking on bright days, a lightweight comfortable fit means you won’t end up pushing these up on your head every 20 minutes, while a slightly grippy nose pad ensures there’s no danger of these slipping off and crashing to the ground when you’re scrambling or rooting through your hiking backpack. The 8KO lenses deliver full protection on brilliant days and perfect clarity of vision, even if you’re hiking near water or on snow, plus the frames offer good coverage from above your eyebrows to mid-cheekbone. 

Priced reasonably compared to similar hiking sunglasses, these sunglasses boast resistance to scratching as well as oil and water, and they don’t seem to fog up no matter how sweaty you get. Soft, flexible frames with screwless hinges are made from recycled materials and won’t easily break if you accidentally squash them into your backpack or drop them on a rocky trail. They come with a soft, microfiber pouch to carry and clean them, although with a lifetime warranty you can expect to run with these for a long time. Customize the lens and frames to suit your vibe and you’ll love the comfort and visibility.

SunGod Tempests sunglasses: in the field

I can’t say that there’s been an abundance of bluebird days in Scotland lately to test out these sunglasses properly, so I recently packed them up and took them to Spain, where I never saw a cloud in the sky all week. This is my second pair of SunGod sunglasses and in terms of comfort and performance, I’m as impressed as ever.

Here’s how they performed:

Comfort

Being in non-stop sunshine, I basically wore these all day whether I was hiking or lounging at the beach and I didn't once recall removing them to give the bridge of my nose or my ears a breather. They feel great and are super lightweight so I barely notice them on my face.

Staying power

These sunglasses aren’t at all tight on my head, but the grippy nose pads and flexible arms mean that whether I was gazing up at the sky or had my head down rummaging through my backpack for water, they never slid off and met the same fate as many sunglasses before them. For running, however, they did slide down a bit when I have sunscreen on my face.

Visibility

I wore these on a hike up a mountain that rises straight out of the ocean so there was some serious glare going on and my vision wasn’t affected at all. I don’t understand the inner workings of SunGod’s 8KO lens technology, but it offers pristine vision, and they never seem to fog up when I get sweaty. The slightly larger frame size offers good visibility too. 

Cleaning and maintenance

The only thing I don't love is that it is a little harder to totally clean the lenses of sunscreen smudge, even using the pouch. It didn’t make much difference to my vision, fortunately, but they do look a little more smudged than I’d like after a week of wear. 

Durability

Rather than being made using stiff plastic, these sunglasses are made using a nylon that’s actually quite soft and pliable. Not only does this help them fit comfortably on your face, it means they feel less brittle and stand up better to being dropped. I was recently wearing them on a super windy day up Ben Arthur in the Arrochar Alps when they were blown clean off my head and under a rock. I thought the hinge had broken but in fact the leg had just come out slightly and I was able to easily pop it back in.

Style

Unlike the last pair of SunGods I tested, I absolutely love the way these sunglasses look. The bigger frame is flattering, and I chose the navy frames with gold lenses which gives mine a classic look, while the plastic frames don’t look cheap at all. These are definitely my go-to sunglasses for everyday wear as well as hiking now.

• How Advnture tests products

If you spend a lot of time outdoors, you've probably had a hitch with your sunglasses at some point, either wearing a pair that were too dark, meaning you had to take them off and squint all day long, or a pair that were too light for the amount of sunlight leaving your eyes feeling strained at the end of the day. 

Your eyes need as much protection from the sun as the rest of you – arguably more – since we rely on sight so heavily in the outdoors. Selecting the best sunglasses for hiking and mountaineering is a crucial decision-making process, with UV exposure being accentuated at elevation and potentially damaging glare from snow and ice a real issue.

And if you're picking out a new pair for outdoor trail running, there's a lot more to consider than how they look. Sunglasses for trail running need to be lightweight and stay put when you’re bouncing along the trail, for example, whereas you’ll need to prioritize polarized lenses if you’re going to be snowshoeing in extremely bright conditions like in Colorado. Then there's the question of how much light your lenses allow in, which is determined by a criteria usually known as VLT.

VLT then is obviously an important factor to consider, but one that can seem kind of confusing at first. In this article, we explain what VLT means and what the different categories are used for, so you don’t end up picking shades that are too light – or dark – for your favorite adventures. 

What does VLT mean in sunglasses?

VLT stands for Visible Light Transmission and it refers to how much light passes through the lens of your sunglasses to reach your eyes. It is also sometimes simply referred to as “light transmission” and will almost always be listed as a percentage, though there are categories used to organize them, which we’ll explain in the next section.

There are four factors that affect the VLT of your sunglass lenses:

• Color
• Thickness
• Material
• Coating

Naturally, you want some light to reach your eyes when you’re wearing sunglasses, but too much or too little could really sour an adventure, fast. Just as with ski goggles, you want darker sunglasses for brighter conditions, and lighter lenses for low light ventures. 

Is a higher VLT better?

It’s easy to assume that a pair of sunglasses boasting a higher VLT is better, but unlike UV protection, which you want to see listed as 100%, higher isn’t necessarily better for VLT. Rather, it depends on what you’re using the sunglasses for. There are five categories in total for VLT, but as you’ll see, not all of them apply to sunglasses. 

Here is a general guideline to what the different categories of VLT mean for you:

As you can see, the higher the VLT, the darker the lens, which is only a good thing if you’re planning on using your sunglasses at high altitude or on the water or snow. If you’re recreating in cloudier conditions or at dusk, you’ll want a lower VLT or your sunglasses will be too dark.

What VLT is best for driving?

If you’re looking for sunglasses to wear for driving during the day, avoid anything that’s less than 10% as this doesn’t allow enough light through to keep you safe, and may be illegal. You can wear anything between 10 - 100% for driving during the day and should consider polarized lenses, which help with reducing glare on flat surfaces like the road ahead. Don’t wear sunglasses while driving at night or dusk.

SunGod Ultras sunglasses: first impressions

The SunGod Ultras trail running sunglasses are built with fast-paced and long distance adventures in mind, when the last thing you want to worry about is your eye health on clear days. These sunglasses are so light you’ll barely notice them on your face, and the frameless design means no annoying blind spots; just clear, uninterrupted views. A slightly grippy nose pad means these sunglasses don’t bounce when you’re bounding down the trail and they’ll stay put all day long.

The SunGod Pace Series lenses are not polarized, instead featuring SunGod's 8KO™ lens technology. Priced reasonably compared to similar trail running sunglasses, these sunglasses boast resistance to scratching as well as oil and water, and they don’t seem to fog up no matter how sweaty you get. Soft, flexible frames are made from recycled materials and won’t easily break if you accidentally squash them into your backpack. They come with a soft, microfiber pouch to protect them as well as extra nose pads to prolong their life, although with a lifetime warranty you can expect to run with these for a long time. The look of these sunglasses may not be for everybody, and with only one size available you might find them too large for a smaller face, but if they fit, you’ll love the comfort and visibility.

SunGod Ultras sunglasses: in the field

Sun has been in scarce supply this winter in Scotland, so it took me a while to test these sunglasses out, but a week of extremely cold and crisp weather early in the new year gave me a good opportunity to take them for a few runs along the West Highland Way, where the low light and cold temperatures allowed me to really put these through their paces.

Here’s how they performed:

Comfort

I wore these for about an hour at a time, so not all day, but long enough to be sure that they don’t hurt either of the spots where I sometimes have issues with glasses – the tops of my ears or the bridge of my nose. In fact, I’d say I barely noticed them on my face at all. When I took them off, I did feel a brief pinch on my nose so I had my bigger-nosed boyfriend try them on and he said he thought they might get a bit sore for him after a while, but for me these feel really great.

Staying power

These sunglasses don’t feel snug at all on my face, so I expected them to bounce around and fall off, but the nose piece and ear pieces seem to be made from some kind of grippy nylon that simply stays put, no matter what.

Visibility

Obviously, I want to be able to see when I’m wearing sunglasses and the frameless design means you basically have panoramic views. It was early January so the sun was really low, which is when you need shades the most, and I found these took care of that glare and I didn’t feel like I had strained eyes at all afterwards. I don’t understand the inner workings of SunGod’s 8KO lens technology, but it offers pristine vision. Plus, as I mentioned the air temperature was really cold but I was sweating and breathing hard – perfect conditions for foggy glasses, but these didn’t fog up.

Weight

When I say featherlight, I mean it. These sunglasses tipped my kitchen scale at half an ounce, which adds to that barely there feel.

Durability

Rather than being made using stiff plastic, these sunglasses are made using a nylon that’s actually quite soft and pliable. Not only does this help them fit comfortably on your face, it means they feel less brittle. They’re definitely the priciest sunglasses I’ve ever owned, so I won't be shoving them in my backpack any time soon, but I do think they’ll hold up better against a little accidental abuse from time to time.

Style

Personally, the look of these sunglasses is not for me. They look a bit like the safety goggles you’d wear in a lab or working the line at a meat processing plant. Now, do I care how I like on the trail if it means my eyes are protected, I can see and I’m not worried about them falling off when I’m leaping over boulders? Absolutely not. But I wouldn’t also wear these to the beach or for everyday wear. I look mad in them. However, I don’t necessarily see that as a downside, because it means that I’ll keep them for trail running and won’t end up breaking them at après.

We're pitting ski goggles vs sunglasses to see which is truly the better choice for the ski slopes and your wider adventures. For a long time now, ski goggles have been the eyewear of choice on ski slopes around the world, but you will still see your fair share of skiers and snowboarders hitting the hill with wraparound polarized sunglasses instead. 

If you’ve had problems with your ski goggles fogging up, don’t want to spend the perceived extra cash on a pair of goggles or find their bulk annoying to lug around, you might be wondering if you can wear sunglasses instead. They certainly look better in the bar afterwards, but do they really offer enough protection for the slopes? 

Let's examine the merits and pitfalls of both to ensure you make the safest – and not just the easiest – choice for your snowsports adventures this winter.

Protection

• Ski goggles provide more protection and are more secure than sunglasses

Let’s start with the most important criteria: how much protection does each option offer you? When you’re skiing or snowboarding, you’re subject to high speeds, the elements and even the occasional branch or other flying object, so you need to get serious about protecting your eyes and face.

Ski goggles cover more than half your face and seal to your skin, which means they protect both your eyes and face from the sun’s UV rays and seal out the wind, snow and anything else that flies near your face. Wraparound shades will do a decent job of protecting your eyes from the sun, especially in conjunction with your helmet, but they don’t cover your face and won’t keep out the elements or much else out, plus they can more easily be knocked off your face.

Insulation

• Many skiers value the added warmth ski goggles provide for their face
• Sunglasses don't provide protection from the cold

Cold temperatures mean great snow, and you might not think of either piece of gear in terms of keeping you warm, but ski goggles actually provide quite a bit of welcome insulation, by sealing out cold air. Most skiers rely on just their goggles to keep their face warm, while the colder skier can also use a neck gaiter or ski mask for their lower face. Sunglasses don't provide any protection from the cold.

Helmet compatibility

• Helmets have a clip at the back to attach goggles
• With sunglasses, you don't really need to worry about compatibility

We’re just going to go ahead and assume that you’re smart enough to be skiing or snowboarding with a helmet, and you’ll want your eye protection to be helmet compatible. You’ll wear the band of your ski goggles on the outside of your helmet. All new helmets have a clip at the back to attach your goggles, and all new goggles worth buying should be helmet compatible, so if you’re shopping today, you shouldn’t need to worry – but it is good to check that your ski goggles are compatible with your helmet so that they stay in place and aren’t too tight. 

With sunglasses, you don’t necessarily need to worry about compatibility, however you want your helmet to be nice and snug so it might be a little uncomfortable to have the legs of the shades pressing against your temples.

One other place your helmet comes into play is when you stop for a break or head to the lodge for apres. Goggles are easier to just push up onto your helmet without losing them (however this can lead to fogging) while sunglasses will need to come off your face and go into a pocket for safekeeping.

Fogging

• Goggles can fog up much more easily than sunglasses
• However, if you know how to wear your goggles correctly, you can avoid this

One annoying aspect of ski goggles is that they can get fogged up easily, which obscures your vision and means you have to keep pulling them off on the chairlift to wipe them, which can leave you with scratched lenses. One advantage sunglasses have over ski goggles is that they tend not to fog up as easily, however if you know how to wear your goggles and what not to do, you can avoid this nuisance, so read up on how to stop ski goggles from fogging and you’ll be perfectly happy.

Weight and packability

• Ski goggles weigh more and are bulkier than sunglasses

Ski goggles weigh more than sunglasses and are bulkier too, especially since you’ll want a good case to carry them in. This does mean they’re not as easy to stick into your pocket, so make sure you get a ski jacket with roomy pockets (our guides to the best ski jackets for men and ski jackets for women are full of great options). Sunglasses are light and can fit in almost any pocket.

Durability

• Ski goggles tend to be much more durable than sunglasses
• Both could be carried in protective cases

Speaking of sticking things in your pocket, that’s a great place to break a pair of sunglasses. Even the best sunglasses are flimsy in comparison to ski goggles – you can easily break the legs off or pop a lens out. Ski goggles are much more robust. The main issue is one which also plagues sunglasses and that is the problem of scratched lenses, so make sure you carry both inside a protective case and don’t use your clothes to wipe them (read up on how to clean sunglasses the right way).

Versatility and prescription

• Sunglasses are more versatile than ski goggles
• Getting prescription sunglasses is relatively straightforward
• Some goggle manufacturers offer prescription inserts and some can be worn over regular glasses

It’s fair to say that your ski goggles have pretty much only one function, and that’s to protect your eyes while you’re skiing or snowboarding. Meanwhile, you can wear your sunglasses for hiking, trail running, water sports and hanging out any time it’s sunny. So, you’ll get more use out of your sunglasses year-round for the price.

If you wear glasses in everyday life, it will be easier (and probably cheaper) for you to get prescription sunglasses, but most of the bigger ski goggle brands do now offer prescription inserts for your goggles, and you can even find ski goggles that can be worn over your glasses.

Price

• High performance sunglasses tend to cost more than their goggle counterparts
• However, it's easier to find budget sunglasses too

As a specialty item, you might assume that ski goggles will cost more than sunglasses, but when it comes to high quality sports eyewear, you’d actually be wrong. The average price of ski goggles that we’ve tested is $123, while the average cost of a pair of trail running sunglasses that we’ve tested is $154. That said, you can obviously much more easily find a very cheap pair of sunglasses than goggles at the gas station on your way to the mountain, just make sure they offer full UV protection. And as we’ve already established, you’ll probably get more wear out of your sunglasses for your money.

Comparison table

The verdict

For this debate, we think that ski goggles are the clear winner for skiing and snowboarding. They offer far better protection than sunglasses and you can’t really put a price on that, though if you were to place a price on it, it seems it would still be cheaper than buying a high end pair of sunglasses. They’re also sturdier than any pair of sunglasses. The only real savings you make with sunglasses are that they’re lighter and easier to transport in your pocket, and don’t fog up as easily, but take good care of your ski goggles and they’re the best choice no matter what conditions you’re experiencing.

• The best ski gloves: keep your hands warm and comfortable on the slopes

Wearing sunglasses as a runner can take a little getting used to – as well as some time finding the right pair – but few of us would deny that the benefit for your eyes far outweighs the annoyance of having something on your face while you run. Once you get a good pair of sunglasses for running that stay put, however, you won’t even notice they’re there. 

A running hat, on the other hand, can seem like a step too far. Perhaps it feels annoying or you’re worried it will blow off in the wind, or maybe you just assume you’re getting all the protection you need from your sunglasses. In truth, in the battle of running hats vs sunglasses, it’s not really an either/or decision as a running hat will provide several important benefits that your sunglasses won’t.

Here’s why you need to wear a running hat as well as sunglasses:

1. Cools you down 

Sunglasses are key to keeping the sun’s glare and harmful UV rays from damaging your precious peepers, but they won’t do anything to keep you cool. A running hat keeps heat from the sun off your face, and if it’s made from the right materials, it also helps reinforce your body’s natural cooling system. Though we often instinctively reduce clothing when it’s warm out, there’s no replacement for moisture-wicking clothes which help keep us cool while pulling sweat away from the skin. 

Make sure you wear a hat made from a synthetic material like polyester, not cotton, and it will help draw the sweat away from your head and face which helps cool you down. Mesh panels on the sides of your hat will get you the benefit of a little air flow, too, and a light-colored hat will be better at reflecting the sun’s rays than a dark one.

2. Scalp protection 

Sun protection is especially important for athletes – a 2009 article in Sports Health found that marathon runners have an increased risk of developing skin cancers. Your eyes aren’t the only thing at risk from harmful UV rays while you’re out running of course, and while a mixture of clothing and sunscreen helps to protect your skin, your scalp is one area of your body that’s on display all day.

If you’re thin or bald on top, you’re hopefully pretty aware of this vulnerable spot and keep it covered most of the time anyway, but even a thick head of hair can come away with a sunburn that may go undetected until you notice dandruff a few days later. Whack a running hat on and you’ve no need to worry about a toasted scalp.

3. All weather protection 

Of course, your hat will provide some UV protection for your face too, but in lots of places, the sun is the least of your worries when it comes to the weather and you’re more likely to be trying to fend off driving rain than you are the sun’s glare. 

Wet weather protection is another place where your running hat performs a role that your sunglasses can’t, by keeping rain, sleet and snow off your face. In heavy rain, sunglasses definitely help keep the rain out of your eyes, but your hat will offer much better protection for your whole face which can reduce painful icy pellets hitting your skin, increase visibility and help you breathe better in a deluge, all of which ultimately improve your performance.

4. Hair control 

This one won’t matter for everyone of course, but if you do have hair long enough to pull back in a ponytail, you might be well-acquainted with the battle of it coming undone as you bound along the trail, which can be annoying and slow you down. One of the handiest parts of a running hat is being able to pull your ponytail through the hole at the back to help secure it better, while the whole thing acts like a running headband and keeps your hair out of your eyes and face nicely so you can concentrate on running. 

• Best trail running shoes: footwear for speed on tough terrain

The importance of sun protection isn’t limited to the summer months, especially when you love hitting the trails. You can get sunburn at any time of the year and lots of the terrain that you like to adventure on or near – such as water and snow – reflect the sun’s UV rays, making them more harmful to your skin and eyes. Our sun protection tips for hiking and running cover everything from choosing when and where to go, to how to dress when you’re on the trail, to help keep you safe in all seasons. 

1. Timing 

The sun’s rays are strongest in the middle of the day, so try to get out first thing in the morning if you can, or in the late afternoon, limiting your time outdoors between 10 a.m. and 4 p.m. Dawn and dusk make beautiful times to be outdoors anyway, with less intensity from the sun. If you’re going out on a full day hike or long run, check out our tips on location to choose your trail wisely. 

2. Location 

When you’re going to be out all day, or in the middle of the day, look for north-facing and shaded trails with lots of tree coverage and avoid hiking near water, snow and sand, which reflect the sun’s rays and increase your UV exposure. 

3. Clothing 

When the sun’s out, many of us are tempted to expose as much flesh as possible to stay cool and slap on the sunscreen, but your hiking and running clothes provide important UV protection and many are designed to keep you cool, too. In general, dark colors absorb UV rays more so choose light colored clothing, and know that denser fabrics like synthetics and wool provide better UV protection than cotton and linen.

How you dress depends on your preferences as well as the climate and season, but generally speaking, look for breathable, moisture wicking fabrics such as merino wool, bamboo, nylon and polyester and in doing so you’ll be able to wear long sleeve base layer tops and trousers even in warm weather. Make sure your top fits close to your skin to properly wick sweat, but don’t wear one that is too tight as the stretched out fabric might let more UV rays filter through. For hiking, look for lightweight and loose hiking pants to keep you cool if it’s warm. 

Of course, of the utmost importance is a good brimmed hiking hat or running hat to protect your scalp, face and the back of your neck.

4. Sunglasses 

In addition to your hat, sunglasses for hiking and running are vital to protect your precious peepers from sun damage. Because your hiking and running sunglasses can get a little beat up, it’s common to keep a cheap pair for the trail, but you still want to make sure that the pair you use block UV rays, which will be indicated by a sticker on the lenses when you buy them. Remember that polarized sunglasses offer better protection against the glare from water and snow, but won’t come with UV protection unless labeled as such. Learn more in our article about the differences between polarized and non polarized sunglasses. 

5. Sunscreen 

For any skin that’s going to be exposed, you should apply sunscreen with broad spectrum protection that is SPF 15 or higher. Once you’re dressed, apply the sunscreen to all exposed areas like your hands, face, ears and neck about half an hour before going outside. It’s a good idea to apply it a little below your collar and cuffs to account for clothing moving once you get your backpack on. If you’re going to be outdoors for longer than two hours, carry the tube of sunscreen with you so you can reapply every two hours, especially areas where clothing or straps might be rubbing it off. Also carry lip balm with SPF since eating and drinking water can rub sunscreen off your lips faster than elsewhere. 

6. Check the weather forecast 

In addition to checking your favorite weather app for the temperature and chance of rain, check the UV index too. The UV index predicts the strength of the sun in a particular location on a particular day and on days when it is listed as high or extreme, you want to take extra precautions.  

• What to wear hiking in hot weather

If you’ve picked out a good pair of sunglasses for hiking, trail running, biking or winter sports, the chances are that you’ve spent a pretty penny on them to make sure you get a pair that stay in place when you’re on the move, feel comfortable on long treks and, most importantly, protect your eyes from sunlight and other trail hazards.

Great sunglasses like the best trail running sunglasses don’t come cheap and are relatively fragile, and that’s why it’s imperative that you don’t form bad habits with them. You know, like wiping the grease off them with your hiking shirt or shoving them in your hiking backpack without placing them in their protective case first. 

But no matter how careful you are with your sunglasses, they’ll still end up smudged, whether they’re collecting grease and hair products from when you push them up on your head to stop and read your map, or gathering sunscreen from the bridge of your nose, and while you might think that you’re doing a great job of cleaning them, your method could actually be doing more harm than good.

Using the wrong types of cleaning solutions or fabrics to clean your sunglasses can accidentally leave the lenses scratched or permanently cloudy, which is no use at all when you’re moving fast on a technical trail or trying to check your location on your phone. In this article, we explain how to clean sunglasses properly — don’t worry, it’s super easy — and what you should avoid cleaning your sunglasses with.

What should you not clean your glasses with?

First, let’s start with what not to do. Generally speaking, anything that’s abrasive is a no-go, and while you’re probably smart enough not to be using a brillo pad to scour your lenses, you might be surprised to learn that lots of household items that you commonly use for wiping or cleaning your sunglasses are scratching the surface of your lenses. Here’s a short list of items to avoid using on your lenses:

• Clothing
• Paper towels
• Toilet paper
• Napkins
• Tissues
• Surface cleaners
• Glass cleaners
• Vinegar
• Any cleaner containing bleach or salt

What is the best way to clean dirty sunglasses?

When you get home from the trail, it’s really easy to clean your sunglasses properly. A common technique is to breathe on your sunglasses to mist them up, then wipe them, but you actually need much more moisture than your breath can provide. All you need is some warm water, a little dish soap and a lint-free microfiber cloth. Once you’ve gathered these items, follow these steps and you'll be able to enjoy the best views on every hike or run:

1. Wash your hands.
2. Fill a bowl with warm water and a squirt of gentle dish soap.
3. Submerge your sunglasses in the soapy water and use your hands to gently wipe the frames and lenses.
4. Rinse your sunglasses under warm water to remove the soap.
5. Use the lint-free microfiber cloth to gently dry your sunglasses.
6. Place your sunglasses in their protective case.

If you’re out on the trail and your sunglasses get smudged, it’s ultra tempting to wipe them with your shirt but instead, carry some lens wipes with you on your adventures. Blow on your sunglasses to remove any dust and dirt that might scratch the lenses then use the wipe (you can also use it to clean your phone of any smudges). And remember, when you’re not using your sunglasses, place them back in their protective case every time to keep them in good condition.

• How to clean your hiking boots in five easy steps

The days of glancing down at your wrist to check your running stats might soon be over – possibly. A company called MicroOLED is developing a system that can take info from your Garmin, Suunto, or Apple Watch and beam it straight onto a pair of sunglasses so you can see it right in front of you.

As the5krunner reports, MicroOLED's platform is called ActiveLook, and uses a tiny module that can be fitted to a pair of shades, goggles, or even a motorcycle helmet to provide data in a heads-up display. The information appears with a virtual projection distance of 4m, allowing you to concentrate on the trail ahead rather than focusing on something close to your eyes.

The unit, demonstrated in the video below, will let you choose which data you want to see and display it in real time, with options such as time, distance, speed, elevation gain, power, heart rate, and calories burned.

The ActiveLook unit connects to your watch via Bluetooth, and has a battery life of around 12 hours, after which it needs to be connected to a magnetic charger. It also features an ambient light sensor, which can presumably alter the brightness of the display to suit the ambient conditions (brighter during sunny weather, and dimmer in lower light).

Rather than using buttons or voice controls, ActiveLook is controlled using gestures; a thoughtful feature that means you don't need to touch your glasses or visor, and can use the HUD in noisy environments.

It's always wise to wear a pair of the best trail running sunglasses to protect your eyes from UV damage, and having stats visible at a glance would make them even more useful. We don't yet know when ActiveLook might actually be available in a product you can buy, but MicroOLED offers an open API for developers, and MapMyRun, Strava, Garmin, Suunto, and Apple all seem to be on board, so we're cautiously optimistic.

• Best Garmin watch: find your ideal training tool

There are all different types of sunglasses for hiking and trail running, not to mention winter sports and water sports, and no matter what you need them for, you’ll notice that they’re often broadly divided into two categories: polarized vs non-polarized sunglasses. But what does this actually mean, and do you need polarized sunglasses? We shed some light on the main differences between these two types of sunglasses to help you choose the best pair to protect your peepers when you’re adventuring outdoors. 

Polarized vs non-polarized sunglasses: what are they? 

The main difference in the technology of polarized vs non-polarized sunglasses comes down to their protection against glare, which is when you have trouble seeing in the presence of bright light such as direct or reflected sunlight or even oncoming car headlamps set on high beam. Polarized sunglasses have a chemical coating called a polarizing film, which helps protect your eyes against glare by blocking out horizontal rays of light while letting vertical rays in. Non-polarized sunglasses are any that don’t have this coating. Let’s read on to find out what kind of difference this makes in terms of their performance on the hill. 

Polarized vs non polarized sunglasses: glare and visibility 

As we’ve explained, polarized sunglasses are effective against glare, which makes them useful in extremely bright situations such as during water sports and skiing, where the light reflects off the water or the snow. Polarized sunglasses will offer better clarity and contrast and reduce eye strain in these very bright situations, and are helpful to help you avoid hazards on the trail or the ski runs. This will be really helpful if you’re skiing in Colorado, where there’s seldom a cloud in the sky. 

Non-polarized sunglasses lack this coating, so you may find it harder to see in situations where there is high glare, but they may be just fine for hiking somewhere with more cloud coverage, low reflective situations, or just hanging out in the summertime. 

Polarized vs non-polarized sunglasses: UV protection  

Non-polarized sunglasses may not protect your eyes as well against glare, but they do typically offer ultraviolet (UV) protection, which is hugely important, especially when you're hiking or running at high altitude where it can be a lot brighter. UV rays are the rays from the sun that can be harmful to your skin and eyes. 

Polarized sunglasses don’t necessarily filter out UV rays unless labeled as such, but basically regardless of which type you choose, you should make sure that they offer full UV protection before you buy a pair. The Shady Rays Velocity in our picks of the best trail running sunglasses are polarized sunglasses that offer 100% UV protection at a decent price. 

Polarized vs non polarized sunglasses: color distortion 

When you’re out in nature, you want to enjoy the best views you can, and save the rose-colored views for retrospection only. While color distortion is partially a product of the color of your lenses, it may help your decision making process to know that polarized sunglasses generally lessen color distortion. That said, look for gray and green lenses if you’re looking to minimize color distortion, and avoid brown lenses. 

Polarized vs non-polarized sunglasses: use with screens 

Let’s face it, chances are when you’re out on sunny adventures, you’re going to want to have a peek at your screen from time to time, whether you’re checking your hiking route on Komoot, snapping pics of your ski vacation, or relaxing by the pool with your e-reader after a long trail run. The extra protection against glare offered by polarized sunglasses can also make it a bit harder to see your screen, though this is slowly improving with technological advances. Non polarized sunglasses are preferable if you’re going to be looking at a screen a lot. 

Polarized vs non polarized sunglasses: price 

That extra protection offered by the polarized film does come with a higher price tag, but that doesn’t mean that all polarized sunglasses cost more than all non-polarized versions. Plenty of both versions come with a hefty price tag, but essentially what you will see is that when comparing a model of sunglasses which comes in both polarized and non polarized options, such as the Julbo Montebianco 2 / Monterosa 2, the polarized version will be more expensive. 

Polarized vs non polarized sunglasses: the verdict 

This one seems pretty clear cut to us: if you’re going to be outside in extremely bright situations, or where there is a lot of reflected light from water or snow, it’s really worth paying a little more for a pair of polarized glasses to help you see well. That said, you should absolutely make sure that you get a pair of sunglasses with added UV protection. For lower light adventures, non polarized sunglasses offer all the protection and visibility you need. Of course, you can get a pair of each and wear the best pair that the day’s escapades demand. 

• How to choose sunscreen: advice for runners and hikers

The best trail running sunglasses are an essential piece of kit, whatever the season. As we lace up our trail running shoes and hit the hills, coast paths and mountains in spring, we obviously require protection against the sun.

That's not to say you don't need protection from UV in the winter of course. However, in spring and summer, the sun's UV becomes more intense due to the tilt of the Earth towards our parent star. The need to protect our eyelids, lenses, corneas and retinas from this damaging light becomes more and more important.

The best trail running sunglasses are designed with exertion in mind, with features that help them ventilate and stay secure as we bound along. It's these features that set the best trail running sunglasses apart from everyday pairs.

Our testers have been hitting the mountain trails in the 11 pairs featured here to bring you this guide. Team them with a pair of the most comfortable trail running shoes and you're in for a smooth sprint.

The quick list

This is the quick list, a snapshot of the best trail running sunglasses available in 2026. To delve deeper into the features and qualities of each featured pair, see our more detailed reviews further down the page in this guide.

The best trail running sunglasses 2026

The best trail running sunglasses overall

If you can pull these glasses off, they’re an excellent, ultralight tool to protect your peepers from flying insects, grit, mud and everything else the trail may well throw out you out there. But that is quite the ‘if’. Because these sunnies are "brash and bold" according to our expert tester, and you need to have something about you to style them out. Those who don’t naturally have this hard-to-define ‘something’, will spend quite a bit of time feeling very self-conscious whenever there are other people around.

But, on remote trails and quiet coastal tracks, even we have to admit that – while the style is a bit out-there – the Ultra Evo are excellent running glasses. They’re fantastically light, and the minimalist, top-only frame is completely invisible when they’re on your face. There are vents at the top and bottom of the excellent lenses, which allow air in and prevent fogging. The lenses themselves supply superb high contrast, so you can see every bump and trip hazard on the trail. And the frames are very grippy, keeping the sunnies firmly in place, without being uncomfortable. They come with a big zip-shut rigid case to keep them safe, and a little pouch made from a material you can use to clean the lenses.

The best trail running sunglasses for color contrast

Oakley has just re-released its SubZero shades – a classic design, which was originally launched in 1992 and, despite being discontinued three years later, became iconic among runners. The big boast of these glasses was that they weigh under 1oz – which isn’t less than zero, of course, but let’s not split hairs, because it is very, very light, and was especially so back in the early 90s.

On test, we found that the grip is excellent at the temples and nose, and we were able to shake our heads around or look down as much as we liked without fear of them falling off. The ‘no-slip’ Unobtainium nose grip is pretty chunky, however, and while you might not feel that it’s there, you can see that it’s there, which some people might find a little distracting. Oakley’s Prism lenses are superb, coping well with changing light levels and providing amazing definition and color contrast, as well as complete protection from the harmful effects of the sun’s rays.

They're statement sunglasses – there’s no getting away from that, from the prominent (and cleverly design integrated) logo to the overall chic. In terms of performance, though, our reviewer says that "these are fantastic trail running sunglasses for taking on any active pursuits."

The best trail running sunglasses for versatility

"It’s hard to find a pair of sport sunglasses that seem to do it all" says our expert tester. Yet in the adidas SP0057, she may have found just to pair. Whether you want to run, bike, ski tour or simply seem stylish, these check all the boxes. This is especially so with the style known as 02L, which are photochromatic, with lenses that adjust to variations in light conditions.

Marcolin, an international eyewear company founded in Italy, was specifically chosen by Adidas to design and be the officially licensee of Adidas eyewear because of their ability to access premium materials. And this quality is very apparent in all the Adidas eyewear we have tested. A frame material from Marcolin, known as TR90, is ultra-lightweight and flexible. On test, during a morning trail run in Sedona, we found the lightweight frame stayed put, with no bounce. The adjustable nose pads and flexible temples with rubber on the interior make for personalized comfort and a grip that doesn’t give way. The aeration system of the SP0057 sits right above the nose near the center of the brow line with nine holes to prevent fogging.

Switching to the adidas SP0057 sport sunglasses with the 92Z style mirrored lenses for mountain biking, we found them perfect for shielding the bright sun and staying put as we bounced and rolled over red rocks.

The most understated trail running sunglasses

The classy looking Montebianco 2s are lightweight, hardwearing sunglasses for use on mountain trails, whether you’re running or hiking. On test, we found the fit was extremely comfortable, no matter how long we wore them, and the low-profile, shock-absorbing nose-grip was non-invasive and invisible to the wearer. They feature subtle, but very effective side glare shields, which are easy to remove when not required and equally simple to put back on.

The Montebianco 2’s frame is flexible and robust, and can "put up with a bit of rough-and-tough trail treatment" according to our expert tester. It withstands getting knocked around in a backpack or pockets – just make sure you protect the lenses with the material pouch that comes with the glasses.

There are three choices of lens quality: the standard, non-polarised Spectron 3 lenses are the cheapest, and are perfectly adequate for adventures on open terrain; the Spectron 3 polarized lenses reduce more glare and offer better definition when you’re looking at water and skyscapes; while the considerably more expensive Reactiv Polarized glare-control lenses are photochromic, dynamically adapting to the light conditions wherever you’re running and providing optimum visual performance.

The best trail running sunglasses for moisture management

One of the keys to a pair of the best trail running sunglasses is simply being able to see the terrain below you and the features around you. The lenses of the aerodynamic Flight Jacket model have a large surface area and an open-edge brow to optimize a wide scope of vision. The nose bridge and ear pieces were specially designed to allow maximize air flow and reduce fogging during high-intensity, high-sweat activities on warm days. On test, we found they did exactly this, no matter the level of exertion.

The Flight Jacket comes with numerous different frame colors and three styles of high-impact protective lens options — Prizm, Prizm Polarized and Photochromatic — that can adapt to ever-changing light conditions. It’s hard to beat the performance and style of the Flight Jacket.

It’s built for high-performance running and cycling and our expert tester confirmed that "it’s one of the best of the bunch". Whether you want to invest a big chunk of money is perhaps something you’ll have to put up for debate. You definitely get what you pay for, and that’s a top-tier pair of shades that won’t let you down.

The best trail running sunglasses for brand aftercare

Built for fast-action sports, the Velocity sunglasses move with you as you’re bobbing up and down during a trail run, shield the sun and, on test, we found they didn't inhibit our field of vision. The premium ice blue mirror lenses are polarized, shatter-resistant, anti-reflective and offer 100 percent UV protection. The flexing temples and rubberized nose pads keep these shades in place, while the rimless bottom provides an unobstructed view of obstacles and debris on the trail. Intended for a small-medium fit, "the Velocity sunglasses look as good as they perform" according to our expert.

Shady Rays burst on the scene as an Internet startup brand offering affordable sunglasses. Those kinds of brands are plentiful but most are hawking cheap, disposable glasses. The difference is that the quality, performance and style of Shady Rays sunglasses, which are on par with much more expensive models. Shady Rays will even replace your shades if you break them.

The best trail running sunglasses with an urban aesthetic

The small town of Manitou Springs, Colorado, is tucked between the sprawling city of Colorado Springs and the purple mountain majesty of Pikes Peak. It’s a trail running mecca and the place where we tested the Colorado-made Manitou shades. There’s no place better than experience Zeal’s AutoSun lens technology – which combines with photochromatic variable light capabilities and polarized protection – "ideal for long mountain runs full of partly sunny and partly cloudy moments" according to our expert.

The superlight frames are made from an eco-friendly bio-resin that’s as durable as plastic but much better for the environment. And the best feature might be one of the smallest: the grip pads at the tips of the frame actually get tackier when they get wet from sweat or rain

There’s high value and performance packed into the Manitou, and yes, the price tag is higher than some other polarized shades. But they feature best-in-class optics and are versatile enough to wear trail running, mountain biking or an afternoon relaxing at the pub after a day of high-velocity adventures.

The best trail running sunglasses for aesthetics

Although the Nagata Speed Blade was wear-tested on the streets of New York City, it was designed with distinctive Japanese style and engineering. District Vision says it was developed using the methodology of Kaizen, the Japanese philosophy of continuous improvement. It’s clear from the sophisticated design, with a bottomless, retro-styled frame and advanced lens technology that a lot of meticulous effort went into the design of the Speed Blade.

But perhaps equally as notable was the wear-testing done by hundreds of New York City runners who tried out prototypes in all kidns of weather, light and running conditions, because as cool and stylish as they look, these shades are also "one of the best performing models we tested out on the trails" says our expert tester. The temple tips are made with titanium cores and titanium screws with uniquely styled turned up tips, making it as light and comfortable as possible without sacrificing strength of structure.

On test, we found wind and sweat were no issue. However, it’s the high-transmission, low-glare D+ Sports YellowLens that we found most appealing. District Vision says it’s constructed from a proprietary form of shatterproof polycarbonate with anti-reflective coating on the interior and an exterior treatment for to make it water- and oil-repellant. Is the price tag hefty for a pair of shades? For most of us, yes, it certainly is. But we think this is the cream of the crop.

The best photochromatic trail running sunglasses

The Aero is a super-light pair of high-performance shades with a dynamic photochromatic lens technology that can adapt to low-light or bright conditions, which we found makes them especially good for trail running when it is continually changing from sunny to cloudy to shady.

The unique frame design with a singular suspended polycarbonate Spectron 3CF lens allows for a comfortable fit, exceptional visual clarity and optimal ventilation. The flexible, vented ends of the temples feature a soft, elastomer material that keeps the glasses in place with comfort and a bit of stylish flair.

Considering a pair of Aero glasses is a classic case of cost versus benefit. Will your trail running benefit from investing a little bit more in a pair of shades? Absolutely. On test, we found the photochromatic lens technology was exceptional and ideal for running in variable weather conditions, running in the mountains, running near the coast and, really, as our expert put it: "running anywhere".

The best trail running sunglasses for close-to-the-face design

When you’re moving fast and running all-out, you need your gear to become a part of you. That’s especially true when you’re trail running, because even the slightest distraction can lead to a head-over-heels tumble. The Nike Windshield Elite feature a sleek, close-to-the-face design and a wide, one-piece, wraparound lens that ultimately disappears once you put them on. They offer top-quality optics.

On test, our reviewer found they "gave a full range of vision and all of the comfort and functionality we could need in high-performance situations". The unique design adds ventilation both above the nose bridge and on the top of the frame to help reduce fogging. The floating nose pad helps optimize airflow and absorb impact, while cushioned rubber temple tips add grip and provide long-wearing comfort. For all of those reasons, the Windshield Elite are ideal for race-day efforts and fast workouts.

The best trail running sunglasses for large face profiles

Tifosi has always been known for no-frills, functional, sport-specific sunglasses, but the Sledge is so much more than that. They’re elite-level performance shades with smart design features and an affordable price tag. The curvy frame design hugs around the shape of many medium to large face profiles – however it’s not quite as optimal for trail runners with smaller faces – and the oversized lens give a maximal field of vision. The distortion-free vented lenses are made from a scratch-resistant, shatterproof polycarbonate with an anti-glare coating.

On test, we found that the durable nylon frames were extremely bendable under pressure and have limited edges to maximize the optics and hydrophilic rubber on the tips to grip during high-sweat activities. Sledge shades have a cool look and high-performance features, that "combine fit, functionality and optics," according to our tester.

How we test the best trail running sunglasses

To test these sunglasses, we ran repeatedly with each pair on rough trails and smooth roads, across open sun-blazed hillsides and through woods, where the sunlight was dappled and changeable.

What to look for in the best trail running sunglasses

There are several important things to consider when choosing the best trail running sunglasses. We recommend thinking hard about the following factors.

How should trail running sunglasses fit?

As with trail running shoes and the clothes you wear, the size of a pair of shades and how a particular model fit on your face and head are crucial to a good experience and optimal performance. Like snowflakes, no two pairs are identical. It’s important to try glasses on, if possible, to understand how the frame size, shape and curvature covers your face but also how the nose pads, temples (or arms) and temple tips interact with the specific size and shape of your head, both in a static position but also while you’re running. One key factor to consider is how far the lenses are from your eyes, while it’s also smart to understand how the temple pieces interact with running hats you typically wear.

What should I look for in a pair of running sunglasses optics?

Not all lenses are equal. In fact, the performance of some shades might be greatly superior to others relative to the type of conditions you’ll be running in. While most lenses provide UVA A and UVA B protection, not all lenses offer the glare-reduction of polarization. If you’re trail running in the mountains or seashore where you’re adjacent to snow or water, you’ll want to consider buying a pair of sunglasses with polarized lenses. When it comes to the admission of light, you can consider tints and coatings that make your view appear darker or lighter, but the best-case scenario for trail runners might be a photochromatic lens that adapts to sunny and cloudy conditions. The base curve or arc of the frames can be a factor to consider, but it can often be hard to find. The base curve number tells you how far the frame will curve out. A 6-base curve is considered standard and will fit flatter on your face, while a base curve of 8 will have more curve and wrap around your face.

Can I get prescription running sunglasses?

If you need or want to replace the lenses in your sunglasses with prescription lenses, you should consider this from the start. It’s easier with some brands than it is with others based on the shape and interchangeability of the lenses. Most brands will have information about which models are best for prescription lenses on their websites. You can work with your local optometrist or find an online service or sales site to meet your needs.

Does frame color matter in a pair of trail running sunglasses?

In theory, frame color and lens color shouldn’t matter when you're looking for the best trail running sunglasses, at least in terms of a performance-oriented point of view. But we know that shades are an accessory that carry a bit of vanity in how we wear them. Keep in mind, those sunglasses provide you the protection and performance you’ll need while trail running, but they’ll also appear in race photos and the images you (or others) post on social media. Does that mean they have to match your trail running ensemble? No, but if you’re not particularly keen on how they look when you buy them, you might not like them later on when you’re tagged in a post. Performance is crucial, but to some trail runners with discriminating tastes the look and appearance might be a close second.

How much should trail running sunglasses cost?

The cost of a pair of sunglasses could be the big or small priority when you’re buying a new pair of shades. In one sense, you definitely get what you pair for, but the price is also relative to how you care for your sunglasses. Generally speaking, higher-priced sunglasses from bigger, more well-known brands have good quality lenses, smart features and appealing aesthetics. But they also have a lot of marketing budget built into the price. On the contrary, there are a lot of good (even if more basic) sunglasses available from smaller, start-up brands offered at seemingly incomprehensibly low prices. Some of those are actually quite good, some are complete rubbish, so if you’re shopping on a limited budget for the best trail running sunglasses, you really have to be discerning about the features and quality.

How much should trail running sunglasses weigh?

The weight of the sunglasses typically doesn’t matter too much, except sometimes when they’re too light. It’s typically difficult even to find the weight of a pair of shades as most brands don’t include it in the specs they publish online or on point-of-sale hang tags. Generally speaking, most sunglasses fall in the range of 0.75 ounces (21.5g) and 1.5 ounces (43g) and the difference is barely noticeable unless you’re trying them on in a side-by-side comparison. Typically the shades on the heavier end wind up providing a more secure fit while you’re running, but the super-light frames can sometimes be awkwardly willowy, especially when you’re running fast in hot, sweaty conditions.

Oakley SubZero running sunglasses: first impressions

If these distinctive shades look familiar, you could be giving away your age. Oakley SubZero sunglasses were originally launched in 1992 and, despite being discontinued just three years later, they became iconic. And now 30 years later, Oakley are re-launching this classic design.

The big boast of these glasses – then and now – is that they weigh under 1oz. Now that isn’t less than zero, of course, but let’s not split hairs, because it is very, very light and was especially so back in the early ’90s. Other running sunglasses come close to competing in terms of being lightweight these days, but when you try on the SubZeros they still immediately impress with their barely there-ness. 

Much of the weight savings comes down to the fact that, besides the arms, there is no frame, and the physiomorphic geometry of the large lenses allows the glasses to adapt to the shape of the wearer’s face. This does result in a bug-like, futuristic look (still, three decades after their initial release), but you’re either going to love that or hate it (it may depend on how often you can put up with people saying you look like Bono – other types of sunglasses for trail running are available).

They are statement sunglasses – there’s no getting away from that, from the prominent (and cleverly design-integrated) logo, to the overall chic.

Oakley SubZero running sunglasses: on the trails

In the heady days of the early ’90s, many of us cheerfully assumed we’d be running around in hovershoes by the 2020s, but alas, we’re still waiting for those, and to compensate it seems that we’re going back to the futuristic designs that were popular three decades ago. 

To be fair, while the look of the SubZero sunglasses might not be everyone’s cup of tea, they are a high-performing pair of glasses, with a lot of good features. And they have been updated, rather than simply re-released.

I’ve been running in the new SubZeros along the South West Coast Path in Devon, across open beaches, over bare hills and through the more shady woods in the coastal hinterland, and Oakley’s Prism lenses are genuinely excellent at coping with changing light levels you encounter in such conditions. They deliver amazing definition and color contrast, as well as complete protection from the harmful effects of the sun’s rays.

The grip on these glasses is also excellent, both at the temples and nose, and you can shake your head around or look down as much as you like without fear of them falling off. The “no-slip” Unobtainium nose grip is pretty chunky, however, and while it might feel unobtrusive, I could definitely see it while wearing the glasses, which was a little distracting and made me go a bit cross-eyed until I managed to convince my brain to ignore it.

In terms of pure performance, though, providing protection from glare and enabling clear vision in a range of quickly changing light conditions, these are fantastic lightweight sunnies for running, fastpacking or taking on any other active pursuits.

Julbo Montebianco 2 / Monterosa 2 running sunglasses: first impressions

Julbo have released these sunglasses in male (Montebianco 2, pictured above) and female (Monterosa 2) versions, although, to be honest, the only real differences we can see are a slight size reduction in the women’s model (2g worth) and some different color options.

Regardless, these are really classy-looking running sunglasses, with none of the overtly flashy flourishes you see on so many sunnies designed for runners, but lots of nice lines and tons of performance quality.

Designed for use on mountain trails, for both runner and hikers, they are equally at home at sea level (see Types of Sunglasses for Hiking and Trail Running to see why not just any old sunglasses will do). They’re very lightweight, good and robust and come with removable side panels that provide extra protection from glare. They’re also available in a vast swathe of different colors and with a wide range of lenses, from standard through polarize to fully reactive. (Be aware: some colorways are only available with certain lenses, but trying to list all the variations would have made our specifications box-out look something like War And Peace… and it’s plenty long enough already!)

Julbo Montebianco 2 / Monterosa 2 running sunglasses: on the trails

I tested the good-looking Montebianco 2s while running around coastal trails in the south of England, and fastpacking in the mountains of Wales, and found them to be a very versatile and secure-fitting pair of glasses.

The side glare shields are subtle, but very effective, and they are easy to remove when not required and equally simple to put back on (they are labeled left and right, but you do need to be careful not to lose them). 

The Montebianco 2’s ergonomically shaped arms provide good grip at the temples, without catching on your hair. The fit is extremely comfortable, no matter how long you wear them, and the low-profile, shock-absorbing nose-grip is non-invasive and invisible when you’re wearing them. While running, there is very little movement at all. 

My test pair have standard Spectron 3 lenses, and I did find these to be a tad too dark for trails that venture deeper into the woods. They are excellent on open terrain, across hilltops and beaches, but struggle with the dappled light and changing conditions of forests, which isn’t a surprise. If you regularly run in such conditions, it’s worth going for the Reactiv lenses, which are photochromic, dynamically adapting to the light conditions wherever you’re running and providing optimum visual performance (the price jump is considerable, however).

These are hardwearing sunglasses, with flexible frames that you don’t need to be ridiculously precious about. They will take a bit of rough-and-tough trail treatment, getting knocked around in a backpack or pockets – just make sure you protect the lenses with the material pouch that comes with the glasses.

Many people will think of sunglasses as a fashion product and something extra to wear in the summer only, but eye specialists recommend we make sure we have sunglasses to hand all year round and especially when spending time in the hills and mountains. 

In fact, sunglasses for hiking are recommended as an essential piece of kit and there are many different types of sunglasses to choose from. 

Farah Topia is an optometrist and clinical adviser for the Association of Optometrists. She  says: “Just as ultra violet (UV) light causes damage and premature ageing in the skin, so UV can negatively affect the eyes.”

Sharon Copeland, an optician at Feel Good Contacts, gives greater clarity about the danger of UV rays. She explains that there are three types of UV rays that the sun emits: UVA, UVB and UVC.

She says: “UVC rays are the most damaging but are absorbed by the Earth’s atmosphere before they reach us and are not a direct threat, while UVA and UVB rays can have serious long and short-term effects on the eyes and our vision.”

It's not just in summer that there is a danger form UV rays. Topia says: “In the summer, when it is bright and sunny, people are much more likely to think about wearing sunglasses but we should also be thinking about wearing them during the winter, especially for activities like hiking and skiing.”

UV dangers and risk to eye health

Copeland lists some of the potential health risks caused by exposited to UV rays.

Macular degeneration (AMD): UV rays can contribute to the onset of macular degeneration, a condition where the retina becomes damaged, resulting in central vision loss. This gradual loss of sight often happens as we get older, however increased exposure to UV light can speed up the process.

Cataracts: These are clouds that form on your eye’s lens, obscuring vision and your ability to focus on objects. Studies have shown that exposure to UVB rays increases the risk of cataracts forming, which require surgery to remove.

Pterygium: This is a benign growth that forms on the conjunctiva of your eye as a result of UV light.

Photokeratitis: Typically caused by UVB light reflecting off snow, photokeratitis is caused by high short-term exposure to the rays. Essentially, the eye becomes sunburnt from this light, causing blurry vision or temporary sight loss.

Cancer: Another potential risk is cancer of the eye, eyelids and surrounding skin.

What to look for in sunglasses for hiking 

Fortunately, there are a few precautions you can take to limit your eyes’ exposure to UV rays and keep them safe from harm. There are plenty of factor to consider whether you are looking for the best hiking sunglasses, or the best sunglasses for trail running.

Maya Tailor, a dispensing optician at Whitby & Co. Opticians, states the first and most important factor when purchasing sunglasses for outdoor sports, including hiking, is how well they will protect your eyes from UV radiation. 

She says: “Ideally you want sunglasses with a UV400 protection, which will filter out up to 99% of UVA and UVB rays. You can tell whether sunglasses offer UV protection by checking the frame or labelling for a CE or UV400 mark, which confirms they conform with the EU standards.” 

UV400 refers to UV rays at the top end of the UV spectrum and up to a 400-nanometer wavelength. Sunglasses with this level of protection block an even wider spectrum than the CE and British Standard models, which many eye specialists advise as the ultimate protection for your eyes.

Copeland adds other things to consider when purchasing sunglasses for hiking. She says: “Sunglasses with darker lenses offer the most protection, while wrap around frames and those that sit close to the face offer a fuller coverage of your eyes from angles around the lenses. 

“For extra protection, consider a pair of polarised sunglasses which protect against glare and halos from reflected rays if you are near water or snow. This can also be extra useful when driving.” 

Oculoplastic surgeon Dr Elizabeth Hawkes adds that size is important, too. She explains:  “I would suggest choosing oversized sunglasses because these have a larger surface area of protection, which not only protects the eye itself but also the eyelid skin which, due to the structural complexity and function of the eyelids, is one of the most delicate areas of the face. 

“Oversized glasses are also beneficial for protecting the skin that surrounds the eye area in order to prevent sun damage, which can cause premature ageing and ‘crow’s feet’ around the eyes, as well as poses the risk of causing skin cancer.”

Experts also advise that if you wear clear everyday prescription eyewear, both glasses and contact lenses, you should consider requesting the addition of UV filters. 

Sunglass lenses for hikers

It can be confusing when choosing the right lenses for your sunglasses. These days there are an array of colours, tints and effects.

Dr Susan Sarangapani, consultant eye surgeon at the OCL Vision clinic,  says: “The key thing to remember here is that a darker tint doesn’t necessarily equal better UV protection. Dark tints work best in very sunny conditions, but on cloudier days they can make it hard to see.”

As well as the UV400 rating, which tells you that the lenses are effective at blocking harmful UV rays, there are categories of tint. So, for example, for sunny conditions and especially when hiking, you should consider a category 3 lens.

The category number equates to a percentage of the VLT (Visible Light Transmission) and how much light the lens lets through. The higher the VLT the lighter the lens, conversely the lower the VLT the darker the tint will be, blocking more light coming through to the eye

Category 0 (VLT 80-100%): a clear or very light tint lens – mainly used for impact protection. Many safety eyewear glasses have a clear lens.

Category 1 (VLT 43-80%): typically a yellow or pale / light tint. This lens is not ideal for sunny conditions but fine in overcast conditions.

Category 2 (18-43%): typically  orange, rose blue and red lenses. These are fine for partially sunny conditions and offer a good amount of protection against sun glare.

Category 3 (8-18%): for strong sunlight and the most common category because almost all brown and grey, or smoke lenses, are Category 3. 

Category 4 (3-8%): these typically have a very dark grey or brown lens and they are great in the mountains or desert where the sun is intense and there are high glare conditions. 

Dr Hawkes, who is a Fellow of the Royal College of Ophthalmologists, adds: "’What you’re looking for in sunglasses lenses depends very much on what you’ll be using them for. Tinted lenses are good for certain sports, because they reduce the light intensity and cut the glare, which helps to reduce eyestrain."

It's also important to remember that if you are hiking at higher altitude, near water or snow, the sun's glare and intensity will be greater so you might benefit from a darker tint. 

Another consideration is whether or not the lenses are polarized. Polarized lenses reduce the glare from horizontal surfaces such as water, the road and snow. 

Dr Hawkes says: "Polarized lenses are usually more expensive but are ideal if you’re doing lots of driving or spending time by water.”

Some brands have their own lens technology. For example, Oakley adds PRIZM lenses to some of their sports sunglasses. PRIZM lenses are said to "fine tune vision for specific environments". PRIZM lenses emphasise colors where the eye is most sensitive to detail, which in turn has the potential to enhance performance, safety and your overall experience of chatty you can see around you.

In addition, you'll see many people wearing mirrored lenses. Glare is the primary reason why people choose sunglasses with mirrored lenses so if you are driving or participating in an outdoor sport in sunny conditions, a mirrored lens could be a good choice.

Mirrored sunglasses are also very fashionable just now and they allow you to hide your eyes behind the lenses, if this is something you wish to do. 

However, there are some disadvantages of mirrored sunglass lenses such as the need to take greater care of them to prevent scratches in the coating and also they usually cost a bit more than standard tinted lenses.

What about lens coatings?

When buying high quality sunglasses for hiking, including prescription sunglasses, you might be asked if you want extra coatings. This will add to the coast of your sunglasses but it could be a useful addition if you are rough with your specs, although there appears to be questions about the effectiveness of some coatings.

Dr Susan Sarangapani, consultant eye surgeon at the OCL Vision clinic, says: “If lenses get scratched, they can lose some of their protective qualities – especially their ability to block UV rays. If this happens, you should replace them to ensure they offer adequate UV protection.

“The jury is still out on how effective scratch resistant coatings are. The best way to prevent scratching is to keep your sunglasses in a case or soft pouch when you’re not wearing them. Don’t just leave them rattling around the bottom of your bag.”

Choosing the best frame for sunglasses for hiking

There is a wide range of different frames and colours of frame for sunglasses. If you are hiking you need to make sure the frames and lenses feel comfortable. A good fit is important so that you are happy to wear them for long periods.

If your sunglasses rub your ears or nose or constantly fall down your face, you will be less likely to stick with them.

A popular choice of sunglasses for hikers is a wrap-around frame, which offer a neat fit on the face and protection from the wind as well as the sun. Aside from wraparound styles, the modern look for sunglasses is for larger lenses and this is beneficial because they cover more of the face and eyes. 

Polycarbonate lenses are a good choice, too, because they are lightweight and impact-resistant.

Also look for wide arms at the side of sunglasses to offer more protection from the sun from the sides, as well as rubber or silicone-tipped arms and comfort nose pieces so that the sunglasses stay on your face.

Hinges that open out the way, as well as in the way, are likely to be more long lasting especially if you are in the habit of taking your specs on and off a lot.

Lastly, if you are hiking in more extreme conditions, you choose sunglasses that have side and nose bridge protectors. 

Our verdict on sunglasses for hiking

It's clear that the eye experts recommend that when hiking it is important to have protection from harmful UV rays, even in the less sunny months, and the best solution is a comfortable and high quality pair of sunglasses. Adding a wide-brimmed hat or peaked cap will also give greater protection to vulnerable eyes and the skin around the eyes.

Can you get sunburn in winter? It's a fair question. It's easy to associate UV rays with heat. During summer, we go to great lengths to cover up and protect ourselves from the glaring sun, donning hats, shades and applying suncream by the bucket load. Yet, on a crisp, blue winter's day, the need to shield ourselves from the sun doesn't seem as pressing. When we’re bundled up in layers of clothing, it’s easy to forget or disregard this important practice.

However, can you get sunburn in winter? Absolutely yes. Sunburn can happen in any season when your skin is overexposed to UV rays from the sun. In the summer, it’s true that we're exposed to more UV rays because of the angle of Earth towards the Sun, and that combined with more bare skin on display means we are more susceptible to sunburn. 

However, even though we're exposed to less UV rays when the Sun is lower in winter, you can still get burnt. This usually happens when you forget to put sunscreen on exposed areas of skin, like your face and hands, and also when you’re recreating in areas at high altitude with lots of snow and ice. Just as you wouldn't forego wearing sunglasses or ski goggles to protect your eyes, you shouldn't forget to protect your skin during ski season too.

Meet the expert

Can you get sunburn when it’s cold?

• Temperature has no bearing on UV levels
• On a cloudy day, UV can be almost as strong as on a clear day

Yes, temperature has no bearing on the level of UV radiation from the sun. Furthermore, cloud coverage might make the sun feel less intense and the day less hot, but the level of UV rays on a cloudy day can be similar to that of a bright, blue sky day.

Does snow increase sunburn?

• Snowy terrain reflects up to 80% of the sun's UV rays
• This makes those exploring snowy terrain more exposed to the risks
• The risk also increases at higher altitudes

In particular, when it comes to winter sports, you might actually be more at risk of sunburn. When you’re cross country skiing or snowshoeing, the snow beneath you reflects up to 80% of the sun’s UV rays, meaning that even though the sun is lower, you may be almost doubling your exposure. 

To add insult to injury, UV exposure gets greater the higher you go in elevation, so if you’re skiing or hiking at high altitude, you’re at an even higher risk. And now you know why skiers in 1980s ski movies always had a white streak of zinc oxide on their noses. 

Do I need sunscreen in winter?

• Skin damage can lead to skin cancer, the most common form of cancer in the US
• It's useful to add applying suncream to your outdoor routine, covering any exposed skin

If you’ve only ever had mild sunburn, it may not seem like such a big deal. Just some hot, red, itchy skin for a day or two, right? But a bad sunburn can blister, make you quite ill, and in the long run, damage to your skin caused by UV light can lead to skin cancer, which is the most common type of cancer in the US. Protecting your skin from the sun is an important safety aspect to adventuring outdoors in any season.

Although people with paler skin are at more risk of getting burnt, anyone can get skin damage and cancers. The best approach is to make sure that a good sunscreen is part of your regular outdoor kit. It’s helpful to get dressed in your outdoor gear first so you know what skin is going to be exposed, then apply sunscreen to those areas about 30 minutes before you leave the house. Carry your sunscreen with you as you may need to reapply if you’re outside for more than a couple of hours. 

Other helpful tips

Here are some other helpful tips for protecting your skin against the sun:

• Choose sunscreen with an SPF 30 or higher
• Look for a sunscreen that protects against both UVB and UVA rays
• Use water resistant sunscreen since you’ll probably be working up a sweat
• Reapply sunscreen every two hours
• Don’t forget your ears and part in your hair
• On very sunny winter days, avoid being outside in the middle of the day if possible
• Protect your eyes with UV blocking sunglasses
• Dress in hiking pants and long sleeved base layers that have UV protection
• If you're not wearing a helmet or beanie, wear a hiking hat with a brim to offer shade
