Snow blindness is a condition caused by the exposure of unprotected eyes to the ultraviolet light rays of sunlight reflected from snow or ice. Symptoms can range from eyes being bloodshot and teary to swelling shut. In severe cases, snow blindness can cause permanent loss of vision.
One effective way of preventing snow blindness is to wear sunglasses that offer 99%-100% UV absorption.
