Snow Blindness

Snow blindness is a condition also known as photokeratitis that is caused by exposure to too much ultraviolet (UV) radiation. It is a type of temporary blindness that affects the cornea and is usually caused by prolonged exposure to the sun’s UV rays while on the snow. Symptoms include pain, redness, and sensitivity to light in the eyes, as well as a feeling of grittiness or sand in the eyes. The condition is usually temporary, but in some cases, it can cause permanent damage to the eyes. The best way to prevent snow blindness is to wear sunglasses or goggles that offer UV protection when outdoors.
