Every ski run presents many threats to your eyes. Sunlight and the glare from the snow can be blinding, as can falling snow and a blustery wind. That's why it's important to wear goggles on the slopes. When it comes to goggles, though, one size doesn't fit all, and it's important to wear the pair that fits well and is designed for the conditions you'll be skiing in. Wearing a pair of ill-fitting goggles can be just as dangerous as not wearing goggles at all.
When shopping for ski goggles, consider where and when you'll be doing most of your skiing. Some goggles are designed for bright light, so they tint accordingly, while others are meant for low-light conditions. Bring along the hat or helmet you'll be wearing while skiing to ensure a proper fit, and if you wear glasses, look for goggles designed to fit over your lenses. A good-fitting pair won't have any gaps where snow or moisture could get in. When trying on goggles, ensure that you have a wide field of vision; you'll need that vital peripheral vision to spot skiers veering into your path.
Goggles that fit well have a lesser chance of fogging up, but look for a pair with antifog coating or a ventilation system (such as a tiny fan) to ensure that they don't. In addition to antifog coating, goggles should also provide protection from UV rays. With the right pair of protective goggles, you'll always have the finish line in sight.
