The eye's lens is normally tinted yellow.This reduces the intensity of blue light reaching the retina.When the lens is removed because of cataract, it is usually replaced by an artificial intraocular lens; these artificial lenses are clear, allowing more intense blue light than usual to fall on the retina, leading to the phenomenon.
