Snow Blindness is a painful, temporary loss of vision due to overexposure to the sun's UV rays. The medical term for snow blindness is Photo Keratitis. Snow Blindness can, and often does occur in the absence of snow, as
water and white sand are also highly reflective of the sun's UV rays and
increase the risk of Snow Blindness.
The terms "Snow blind" and "Snow Blindness" are widely used because snow is highly reflective of Ultra Violet radiation, as it can reflect more than 80 percent of the UV rays that falls upon it. Also, Skiing, Mountain Climbing and Snowboarding usually take place at relatively high altitudes, where the sun's UV rays are stronger. Combined, these factors can double your risk of getting Sunburned Eyes, compared with being outdoors at lower altitudes in the summertime.
