What is photokeratitis / snowblindness?


Photokeratitis is a largely reversible sunburn of the cornea, often called snow blindness, resulting from overexposure to UV-B radiation. It can come from spending excessive time at high altitudes in the open air with no sun protection.

The symptoms are usually short-lived and include eye pain, photophobia, excessive tearing and sensation of something in the eye.
