• What goggles should I wear for skiing if I wear glasses?

  Yes, ski goggles are special made for skiiing sports. Wearing the right pair of ski goggles can dramatically improve your day on the mountain, regardless of the type of weather conditions you face. On clear days, goggles can cut the harsh glare caused by the reflection of the sun off of snow and ice, and provide a barrier against dangerous ultraviolet (UV) rays. In inclement weather, they can block sleet, snow and biting windsfrom pelting the sensitive eye area of your face and causing you to squint. As a result, goggles significantly improve visibility - a key advantage when you're navigating unfamiliar trails and hurtling down slopes at high speeds. Goggles also offer valuable protection from eye injuries that could result from common skiing hazards, such as coming into contact with a spray of ice crystals or taking even a minor fall.
