What causes photokeratitis?
Ultraviolet keratitis, also known as photokeratitis, is a painful eye condition caused by exposure to ultraviolet rays, often from the sun. Ultraviolet keratitis can be compared to a sunburn, except that it affects the corneas of the eyes instead of the skin.
Is blue light bad for eyes?
Blue light exposure may increase the risk of macular degeneration.
