Snow blindness or photokeratitis is inflammation of the cornea (the dome-like outermost front part of the eye) caused by UV radiation. Photoconjunctivitis is when the conjunctiva (the mucous membranes on the front of the eyeball and inside the eyelids) are inflamed by UV radiation. Both feel like a sunburn to the eye and are caused by UVB rays.
They can be caused by directly looking at the sun, or by reflected UV from snow, concrete, water, and sand, or from arc welding.
