Photic retinopathy. Photic retinopathy is damage to the eye's retina, particularly the macula, from prolonged exposure to solar radiation or other bright light, e.g. lasers or arc welders. The term includes solar, laser, and welder's retinopathy and is synonymous with retinal phototoxicity.
Eyes, particularly the cornea (the clear window of tissue on the front of the eyeball), can be easily damaged by exposure to ultraviolet radiation from the sun and from other sources of ultraviolet light, such as a welder's arc, a photographer's flood lamps, a sun lamp, or even a halogen desk lamp.
