Blinded by the Snow

Fresh snow can reflect over 90 percent of UV rays from the sun back into your eyes. This may result in "snow blindness" when you spend time outside on a sunny day after a snowfall. The sun's reflection off of the snow can be incredibly powerful. An increase in elevation can make painful snow blindness even worse.

While snow blindness will usually go away on its own within 24 hours, it may cause permanent eye damage. Wearing sun glasses when you go outside or tinted goggles when participating in snow sports can help reduce the risk of damage.
