Glacier glasses aren't your average eyewear. They come with quite a list of perks, both in functionality and protection. In this post, we’re taking a deeper look into what exactly makes this gear item a must-have for mountaineers, climbers, and alpine ascenders alike.

what are glacier glasses


Never settle for any lenses that offer less than 100% UV protection. Luckily, this is a common feature among glacier glasses. With UV protection there are two key types of UV rays your eyes need to stay protected from:

  • UVA: This is the most common radiation, and it can go directly through the eye’s cornea causing damage to both the retina and lens. Long-term exposure to UVA rays has been linked to cataracts, vision loss, and even macular degeneration.

  • UVB: These rays are often found at higher altitudes. Although they aren’t capable of passing through glass, they can still reflect off surfaces and damage eyes.

Something else to watch for is sunglasses that have a UV400 rating. This means the sunglasses are considered top-notch in protection against rays that fall on the high end of the wave spectrum (400 or below), including both UVA and UVB rays.

When light meets a lens it can reflect, absorb, or transmit. How dark a pair of sunglasses are or how high/low their VLT is will be broken down on a scale of 0-4. Each pair of sunglasses is rated on this scale and their measurement refers to the protection they offer.

  • Spectron 4: Though the more expensive option, level 4 offers maximum light protection making them a necessity for mountaineering expeditions. This level blocks upwards of 90% of visible light, and they have the darkest lens.

  • Spectron 3 CF: This rating still offers a high amount of UV protection and glare and is suitable for mountain activities and moderate level expeditions. It will block around 80% of visible light.

There are some excellent benefits to polarized lenses. They minimize glare, contrast different textures, and can help those with sensitivities to light. But do they belong in the mountains?

Some say yes while others say no. The big concern with polarized glasses is how they can make it harder to judge landscapes because of distortion caused by the polarization. This can become a safety concern for mountaineers, especially when spotting crevices and terrain changes are of the utmost importance.

Although lenses can’t be 100% scratch-proof, many have an anti-scratch treatment applied to them which is a hard, clear coating for an added layer of protection.

Naturally, polycarbonate lenses are the most durable, scratch-resistant lenses. Because of this, they’re commonly used in sport shades (including glacier glasses.) It’s not a bad idea to also have a cloth bag or hard case for storing your glasses when not in use.

Another detail you may want to consider is “shock resistance.” What this means is that the glasses are more or less “impact-resistant” and made with materials that can bend and contort easier than a regular pair of sunglasses. They’re also less likely to shatter if dropped.


Sunglass frames determine a lot in the way of weight, fit, and durability. Metal and plastic are the two main types of materials commonly used for frames.

Both have their pro’s and con’s, and really, a lot of it comes down to preference and style per user. Metal frames give off a more “retro” look while they make for a bit of a heavier pair of glasses. That being said, metal is also known for being both durable and flexible. Plastic is often cheaper and lighter, and because of this, it’s used for many modern-day sport sunglasses. One downfall is it doesn’t allow as much pliability or “give” as metal frames.


Side shields are usually made of either leather or plastic. Just as their name suggests, their purpose is to “shield” the peripherals from the sun. Shields can often be removed which is a nice feature if fogging becomes an issue in damp or humid conditions which happens if the sunglasses lack ventilation panels or haven’t been coated with an anti-fog treatment. Many wearers also remove the side panels when hiking at lower elevations where the extra side protection isn’t necessary.

Nose guards are especially important because they give another level of coverage by blocking light from coming in between the eyes. When comparing plastic vs. rubber nose guards, rubber ones with built-in nose pads are more comfortable, a better fit, and they don’t slide as easily.


Glacier glasses are light, usually weighing in no more than 2oz, and that’s on the high end. The weight from pair-to-pair can vary depending on the glasses design, “extra” features, and the materials used for the frame, side flaps, temple grips, and lenses. Although heavier glasses may feel more robust and higher value, they can become uncomfortable if worn over a long period of time. Their increased weight also makes them more likely to slide off your nose.


Sidearms are important for keeping your glacier glasses snug on your face. You'll find models with extendable sidearms that will help you get that perfect fit. Some sidearms are also made flexible at the temple to allow you to wrap them around your ears for a secure fit. In addition, some manufacturers include rubber pads on the inside of the sidearms, or alternatively, make them entirely from a soft rubberish material to increase their adherence. With the latter, it's important you make sure the material doesn't stick to and pull your hair before buying.

There are a couple of style options you can go with: circular and retro or sleek and sporty. This can be left up to preference, although it’s noting that larger lenses have their benefits because they give a bigger circumference of protection around the eyes.

For fit, make sure your glasses have a close and secure fit—both so they stay tight in windy conditions, and because a snug fit seals out the sun and gives better all-around protection.


Most glacier glasses come with some kind of warranty, either two-year, limited lifetime, or lifetime, and the coverage offered varies from brand to brand. Many cover damages relating to manufacturer defects or the big stuff like busted hinges or cracked frames. Some even offer replacement lenses, within reason.

Glacier Glasses FAQ

What Exactly Are Glacier Glasses?

Think of glacier glasses as specially crafted, heavy-duty sunglasses that are meant to do a knock-out job at protecting eyes from blinding glares and dangerous UV rays. Especially in high altitudes.

According to NOAA (the National Oceanic and Atmospheric Admin), UV levels increase by around 5% for every 1,000 feet of elevation above sea level. So, the higher up a mountain you go, the more of a danger solar radiation becomes.

Ever heard the phrase “going snow-blind?” Essentially, this is when eyes get sunburnt. Besides being painful it can also cause temporary blindness. This is a common concern for mountaineers, as the sun’s glare and the high-intensity rays reflecting off the white landscape of snow-covered fields and glaciers can be dangerous enough to permanently damage eyes. Even when it’s overcast!

Glacier Glasses vs. Regular Sunglasses

So, why can’t just a pair of regular old sunglasses do the job of glacier glasses?

To understand this, let’s first look at VLT (Visible Light Transmission).

VLT is a measurement of how much visible light transmits through a lens. For sunglasses, the percentage of VLT also refers to the lightness or darkness of the lens's tint. The lower the percentage, the darker the glasses will be. Glacier glasses are specifically designed to provide high-level protection against intense UV rays. For example, standard sunglasses usually let in around 40-60% VLT while glacier glasses only allow about 4-7%.

Another difference lies in the construction of glacier glasses. The frames are larger and thicker to protect against glares coming in at all angles (from the bottom, top, sides, etc.), and they're made to fit closer and more securely to the face than normal sunglasses.

When to Wear and When Not to Wear?

Glacier glasses are commonly worn by mountaineers, climbers, and for use during ski sports or other alpine activities, although, they can definitely be worn far beyond the mountains.

They’re also great for hiking through the desert, along a high ridgeline, fishing, boating, or even while just hanging around by the pool. Really, anywhere that a high level of sun exposure is a concern, your glacier glasses can go. To make glacier glasses more, well… normal-looking, many pairs come with removable side flaps and nose bridges that, when taken off, make them look just like a regular pair of sunglasses.

Times, where glacier glasses wouldn’t be the best option, are in darker conditions, as the shade of the lenses can become hard to see out of, or if performing an activity where you really need the full range of your peripherals (biking, driving, etc.), because the side flaps and other features can be limiting.
