Which pair of researchers proposed that the human eye has three types of color receptors which respond to different wavelengths of light?

Young-Helmholtz trichromatic (three-color) theory: the theory that the retina contains three different color receptors—one most sensitive to red, one to green, one to blue.

Can IR light hurt your eyes?

Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina. Even low-level IR absorption can cause symptoms such as redness of the eye, swelling, or hemorrhaging.

Why do blind people’s eyes go white?

Not all people who suffer from blindness have ‘clouded’ eyes, but the opaque appearance may be related to the cause of their blindness.
