What is snow blindness?

  • Snow blindness (Photokeratitis) is the painful eye condition.   It can be caused by exposing to natural or artificial UV light without any eye protection. Exposure to UV light affects the cornea and conjunctiva of the eye. Unbearable eye pain, temporary blindness and increased tears are some of the important symptoms of snow blindness.

Photokeratitis or ultraviolet keratitis is a painful eye condition caused by exposure of insufficiently protected eyes to the ultraviolet (UV) rays from either natural or artificial sources.

The injury may be prevented by wearing eye protection that blocks most of the ultraviolet radiation, such as welding goggles  with the proper filters, a welder's helmet, sunglasses rated for sufficient UV protection, or appropriate snow goggles.

Photokeratitis is known by a number of different terms including: snow blindness, arc eye, welder's flash, bake eyes, corneal flash burns, flash burns, niphablepsia, or keratoconjunctivitis photoelectrica.
