Near UV light that is absorbed in the lens changes proteins there causing them to become cloudy (cataracts) which blurs and dims vision. Blue light which is focused on the retina can also induce a photochemical reaction which causes the light receptors in the eye to loose sensitivity. This is known as photo bleaching and mostly effects blue color vision.

Exposure to the invisible carbon dioxide laser beam (10,600 nm) can be detected by a burning pain at the site of exposure on the cornea or sclera. Exposure to a visible laser beam can be detected by a bright color flash of the emitted wavelength and an after-image of its complementary color (e.g., a green 532 nm laser light would produce a green flash followed by a red after-image). When the retina is affected, there may be difficulty in detecting blue or green colors secondary to cone damage, and pigmentation of the retina may be detected.
