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.
Looking at a solar eclipse without protective eyewear can also cause eye damage. Problems with the retina can lead to impaired vision or blindness. Cataracts can be caused from direct, intense ultraviolet rays hitting the eyes over many years. Cataracts are one of the leading causes of blindness. Cataracts develop gradually over a long time. Sunglasses that block 99% or 100% of ultraviolet rays can protect you from eye problems related to sun exposure. Sunglass labels that say UV absorption up to 400 nanometers (nm) provide 100% UV protection.
