Here’s exactly what you need to know about choosing the best glacier sunglasses for you.
If you’re new to the concept of glacier glasses or have never owned a pair before, you might be thinking, why use glacier glasses? What makes them better than regular UV protectant sunglasses?
We’re glad you asked!
If you’re going to be hiking up a lofty mountain, in windy regions where you’re very exposed to the elements, or other high-exposure areas, it is critical to protect your eyes from potential damage. The higher the altitude and the thinner the area you’re hiking in gets, the stronger the UVB rays are. It’s not just your skin that has the potential to get burned—but your eyes too.
It’s pretty hard to predict the weather to precision sometimes, particularly if you’re going to be embarking on a lengthy trek. The weather forecast may predict cloudy skies, when suddenly you get to a crest in the mountain and sunlight streams down with a blinding force.
The good news is, with the best glacier sunglasses in your gear, you’ll be prepared for any sun that comes your way and protect your eyes from damage and burning.
Remember, the higher the altitude you’re hiking in the thinner the surrounded atmosphere is. So, higher altitudes mean way more UV radiation, making it paramount to have the best glacier glasses on hand at all times.
The UV rays elevate anywhere from 10 to 12% every 1,000 meters and can increase further if you’re hiking in snowy or icy regions where the light will reflect.
Whether you’re going to be hiking in an arctic region or regular, snowy area, the reflection of the sun on the snow can cause severe damage to your eyes. Known by its official name, photokeratitis, snow blindness is essentially what happens when your eyeballs are sunburnt.
Photokeratitis can blind you temporarily, occurring when the cornea becomes inflamed from too much exposure to damaging UV rays. The condition commonly happens when hiking on mountains where the snow can transmit and reflect beyond 80% of the powerful rays of the sun.
Even if you’re not dealing with snow, high altitudes where the sun is strong can have the same effect. White sand and water also reflect the sun, and can lead to similar consequences if you don’t protect your eyes properly.
A key component of picking the best glacier glasses for your outdoor adventures is understanding the difference between UV vs. VLT and what these terms mean for your purchase. UV, or Ultraviolet Radiation, is a type of light comprised of 3 parts known as UVB, UVA, and UVC light. UVC isn’t typically as much of an issue because the atmosphere helps to shield your eyes from that type of exposure.
However, UVA and UVB light can pose a real threat to your corneas. UVA and UVB levels elevate substantially as your altitude rises. The best glacier glasses are going to provide you protection against all 3 types of UV bands.
VLT is short for Visible Light Transmission and is a measuring stick for the amount of light that can escape through your lens and into your eyes. For example, some of the best glacier glasses for hiking have VLT ratings between 23 and 25%, while others are far lower at a mere 5%.
Most of the time, you’re going to be adequately protected by glacier glasses with a VLT ranging from 5 to 10%.
It’s essential to choose the right type of lens when hunting for the best glacier sunglasses for your outdoor expedition. Lenses have ratings ranging from 1 to 4, based on the level of UV protection they offer. There is also a 0 rating, but 0 rated lenses are usually clear and designed for safety rather than UV light.
A lens with a rating of 1 is going to be more for style than functionality, so this type won’t be an ideal choice for extensive mountaineering. Category 1 lenses usually allow in 45 to 80% of UV rays. A lens with a 2 rating is something you would wear out and about in your city, which transmits between 20 to 45% of UV rays.
Lenses with a rating of 3 are going to be some of the best glacier glasses to protect you in high altitudes. Category 3 lenses ward off as much as 80% of UV rays and are a solid option to protect your eyes. If you want to take things up to the next level and provide an extra barrier to shield your eyes, lenses with a rating of 4 are going to serve you really well in high altitudes.
Category 4 lenses offer the highest level of protection from UV rays with a quality, low VLT rating. As a note, you should not wear category 4 lenses when driving. Because they only transmit 3 to 8% of the sun’s rays, you’d best wear them at locations like the mountain or at the sea.
The type of coating you can expect for the best glacier glasses is really going to depend on the brand you go with, but it’s a good idea to keep an eye out for anti-scratch coating to extend the life of your mountaineering glasses. Anti-fog coating is another handy feature as is hydrophobic coating, which helps repel rain and dampness.
The most common materials used for the best glacier glasses are glass, polycarbonate, polyurethane, and plastic. Glass resists scratches really well, but isn’t quite as durable. Polycarbonate is super durable but is more vulnerable to scratches.
Polyurethane is the priciest material you can pick, but is resistant to breaking, scratches, and has a really long shelf life. Polyurethane lenses don’t typically require any coating either.
Plastic is definitely not as durable and won’t give you the best views, but this is one of the most affordable materials on the market. For the best glacier glasses though, it’s best to use a more durable material.
