Damage to the clear outer covering of the eye (cornea) from short-term exposure to intense light, such as strong sunlight or an arc welder’s flame. Ultraviolet keratopathy is commonly known as snow blindness. Symptoms include reddening of the eve, severe pain, feelings of grit on the eye, tearing, sensitivity to light, and involuntary twitching of the eyelids. Treatment consists of antibiotic ointment, drops to relieve spasms in the ciliary muscles of the eye covering the eyes, and administering medication to control pain. The condition usually resolves on its own within 1 to 3 days. The risk of ultraviolet keratopathy can be lowered by wearing a hat in bright sun and protecting the eves with glasses that block out ultraviolet light.
