Ski goggles are almost as indispensable as skis. Not only do they keep track of stray patches of snow and grit, they also protect you from harmful UV rays that are reflected by the snow. The thinner air filters less UV at altitude, so more of them get into your eyes, and this, exacerbated by the glare of the surrounding snow, can be detrimental to your eyesight. It's not just squinting at the après-ski lodge – over time, UV light can cause serious damage to your peepers.
It's a bit more complicated because you need different levels of protection for different conditions. That's why we have a Buying Guide that will help you navigate this particular product category.

Do not make the mistake of believing that you only get the lenses with the most protective lenses and call it a day. When it is overcast, it becomes more difficult to spot lumps and bumps in the terrain while skiing. While beginners with a medium rating can probably get away with it, you should choose a pair of interchangeable lenses from the beginner height.
Cylindrical Lenses which are horizontally curved over their face, but vertically perpendicular, are usually the least expensive type of lens as well as the most flexible. They are ideal for easy lens changes.
Spherical lenses are more of a bubble shape: they are designed to curl vertically and horizontally to mimic the shape of your eye. These offer better peripheral vision and there are no blind spots or distortions, and their large surface area also makes them less foggy.
Polarized / Mirrored Lenses have a chemical coating to keep the glare away from the snow. This makes them darker, which has both advantages and disadvantages – on sunnier days they improve visibility and reduce eye fatigue, but on gloomy days you find that you can not see as much as you want.
Photochromic lenses have a special coating that, like varifocal eyeglasses, converts colors in seconds to adjust to the light values. As you might imagine, they are expensive, but they are a far more comfortable alternative to the ever-changing interchangeable lens on days of choppy weather.
If we have an important tip, try the goggles with the helmet; In this way you guarantee that they fit without feeling uncomfortable. Be sure to buy oversized glasses just because they are visible from the outside, as they probably will not fit perfectly in your helmet. Do not pick up a pair: you do not want to be stuck with a "gaper" – this is a gap between your glasses and the helmet and a huge faux pax among aficionados.
Make sure you keep your ski goggles in their protective covers when you're not using them – and not on your head as tempting as that. They are in their suitcases and are much less likely to be scratched or damaged. And if your glasses have no case? We recommend this case from Oakley to keep it safe and sound.

Julbo aviation goggles are one Good choice in search of a hi-tech all-in-one pair. Their award-winning feature is certainly the category 2 through 4 photochromic zebra lens, which adapts to changing lighting conditions in seconds to keep your visibility at the right level for your environment. With these in place, you'll find that every little detail looks extremely sharp and focused, and also provides a premium color brilliance. The glasses are also available in other photochromic variants, including Zebra Light, Snow Tiger and Chameleon, each suitable for specific terrain types.
But what really appeals to us is Aerospace's SuperFlow ventilation system, which allows you to move the lens a few inches away from the frame to increase airflow and avoid fearsome fogging. If we criticize these glasses, it can be difficult to pull out the hinges – especially if you're on the hillside – but it's easy enough to snap the lens back in place.
