The cornea takes the brunt of the damage if proper eye protection is not worn, such as dark glasses or goggles while skiing in bright sun. A corneal flash burn (also called ultraviolet [UV] keratitis) can be considered to be a sunburn of the eye surface.

Burns that penetrate deeper than the cornea are the most severe, often causing cataracts an...
