Actually, visible light with wavelengths of  400-780 nm, can cause photochemical damage to the retina, or a retinal burn. That is one reason it is not a good idea to use a microscope near the window on a very sunny day. Sometimes, visible light can be damaging to the eyes. Infrared of 780-1400 nm can cause cataracts, a clouding of the lens as well as a burn of the retina. If the eye is damaged by a laser, because the blinking reflex is not triggered by the wavelengths of light in a laser, and there is a boiling of the tissue in the eye, this can lead to a blind spot forming.
