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.
In the most famous case of all, Isaac Newton tried looking at the sun in a mirror, essentially blinding himself for three days and experiencing afterimages for months. Scientists don't have a good bead on the prevalence of eye damage after a solar eclipse. In one study, conducted in 1999 after a solar eclipse visible in Europe, 45 patients with possible solar retinopathy showed up at an eye clinic in Leicester in the United Kingdom after viewing the eclipse. Forty were confirmed to have some sort of damage or symptoms; five of those had visible changes in their retina.
