Radiant energy with a wavelength just below that of the visible light that can be a contributing factor to some eye disease processes, including age-related macular degeneration, exposure keratitis, and cataracts. UV-c is the shortest wavelength at 200-280 nm and is absorbed by the atmosphere before reaching the surface. UV-b, at 280-315 nm is the burning rays of the sun and damages most living tissue.
