Ski goggles are people's best choice for high-speed activities such as skiing to reduce the risk of injury. Ski goggles can also enchance comfort and warmth. On clear days, ski 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 winds from 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. source(s) from https://www.dickssportinggoods.com/info/index.jsp?categoryId=12084889.
