You may be surprised to hear that unprotected eyes can sustain just as much damage from the sun in the winter months as they can during the summer, and sometimes more! Did you know that snow reflects 80 percent of UV radiation? That means that when you’re surrounded by snow, especially on a sunny day, your eyes are possibly being exposed to double the amount of radiation they normally are.
If you’re a winter sports enthusiast you need to be even more careful. If you enjoy skiing, snowboarding, snowmobiling or other mountain sports, it’s important to know that the higher the altitude, the more UV radiation. For every 1000 meter increase in elevation, UV radiation levels increase by 10 to 12 percent.
Even if you don’t live in an area where it snows, many people are unaware of how important it is to protect your eyes in overcast weather. Clouds may block the sunlight, making it dark and dreary outside, but they don’t block UV rays. So whether it’s sunny, snowy or overcast, always wear your sunglasses outside!
You may have heard of the term “snow blindness,” but what is it? Snow blindness is a form of photokeratitis, a painful eye condition that occurs when the eyes are damaged by the sun’s UV rays. Put simply, photokeratitis is what happens when your eyes get sunburned.
Snow blindness happens to people whose eyes are unprotected in snowy environments, due to the highly reflective nature of snow and ice—but it can also be caused by sun reflection on sand or water.
Whether you’re a ski trooper or not, your eyes need protecting!
