Melanin-the brown-black pigment found in skin, hair, and eyes.
Layman's explanation:Melanin is found in the skin, hair and eyes. Melanin is a very complex absorbing material and is produced by melanocytes. It also provides protection against UV and visible light. The compound absorbs light smoothly over a broad spectral range, absorbing the higher energy light more strongly than the lower energy light. An interesting fact about melanin is that it has been shown to be a powerful neutralizing agent for free radicals -
molecules which are potentially harmful to the body. In the eye, it occurs in
the retinal pigment epithelium - behind the retina - where its antioxidant
properties help reduce the risk of macular degeneration.
