Winter sports include snow sports like skiing or snowboarding. Without a pair of winter sports sunglasses, eyes are vulnerable to injuries. A bad fall or a low branch, distortions due to fog etc are all perfect recipes for eye injuries. So, winter sports sunglasses are a must while participating in snow sports.
Moreover, eyes need protection from UV rays all year-long and in all weather conditions. In fact, concentration of UV rays increases with an increase in altitude, so donning a pair of proper winter sports sunglasses is even more important.
Most winter sports sunglasses have polycarbonate lenses. This type of lens is most appropriate for winter sports as they are impact-resistant and shatter-proof. Normal glass and plastic lenses can break on impact and damage the eye. Also, polycarbonate lenses are resistant to fogging. This is very helpful as moisture build-up takes place inside the lenses while skiing or snow-boarding.
As for the frames, plastic frames are a much better for winter sports goggles metal frames become brittle in the cold and may snap. Another noteworthy point is that if the wearer falls, the nose pads of a metal frame can poke in the eye. As for the style of the frame, winter sports sunglasses are best suited in wrap around style. The wrap style keeps the wind and snow out of the eyes and this is especially important for people who wear contact lens. Also, in this style, the incidental light coming from the sides can be shut out, thus minimizing the glare.
Winter sports sunglasses often use polarized lenses. Since snow emits a lot of glare, it results in polarized light which often distracts the person from the sport itself. Polarized lenses absorb excessive glare and enable the wearer to differentiate between patches of ice and regular snow.
As for the lens color of winter yellowish lens are best for skiing in bright sunlight. Brown and amber colors are also well-suite as they provide a good contrast against a white background and help see clearly in low light conditions.
