Melanin Absorption of Light “While melanin · Absorbs light efficiently, particularly in the short wavelength region of the solar spectrum, it is · Doubtful whether the photoprotective action of melanin [in the body] can solely be explained by its ability to act as a natural sunscreen. · Indeed, in various model systems melanin [in the body] has been shown to scavenge reactive oxygen species that can be generated by photochemical reactions.”
Antioxidant Effects “This paper will briefly review results of recent studies that demonstrate in vitro antioxidant and photoprotective action of melanin from the human iris and retinal pigment epithelium (RPE)…Our data show that the extent and kinetics of lipid peroxidation in the samples studied correlates inversely with their melanin content.”
“Dr. Burke believes that melanin serves another important protective role in the eye by functioning as an antioxidant. ‘I study · Retinal pigment epithelial cells (RPE), which support photoreceptor cells (those that let you see),’… · ‘RPE cells contain melanin,’ said Dr. Burke, which we believe may act as an antioxidant in young eyes, protecting cells from oxidative damage.” Healthlink: Research Focuses on Age-Related Macular Degeneration
“As we age, however, melanin may change to a pro-oxidant. It then no longer protects, but may actually cause damage.” Healthlink: Research Focuses on Age-Related Macular Degeneration
Melanin and Melatonin, Tryptophan “Melanin, the pigment responsible for dark skin in some peoples and for tanning after exposure to sunlight in light-skinned peoples, · Is produced from the ‘natural’ indole and amino acid, tryptophan. · Melatonin, which is synthesized by our bodies only in the dark, blocks the synthesis of melanin [this is because the body doesn’t need melanin when it’s dark, when melatonin levels increase; there are many positive effects of natural melatonin (but maybe not supplements—supplementswould increase melatonin levels when it is not dark?)]. · Other structurally-related compounds have the potential for either blocking or mimicking melatonin…” VitaleTherapeutics, Inc.: Structural Homology Among Indoles
Additional Information · “Nature provides us with an original supply of melanin at the back of the eye, and · Researchers believe that this melanin offers both photoprotection and vision enhancement. · As we get older, however, this original supply of melanin in our eyes diminishes. So why not put melanin in your glasses? When you look through a pair of MelaOptix glasses, you will be surprised by the brilliant, undistorted color that you see. The MelaOptix Glasses have the · Highest EPF (Eye Protection Factor) values while · Still preserving color and · Filtering out harmful, high-energy light [except for blue light?] from computers and the sun, resulting in reduced eyestrain. When used while looking at your computer, squinting can be eliminated, and your eyes will be relaxed for more comfort. These glasses go beyond UV protection, allowing blues[blue light?], violets and other colors in the light spectrum to penetrate the lens and reach the retina.”
“Do your sunglasses offer protection against · UV rays, · glare, and · blue light? If not, you may want to upgrade to sunglasses made with SunRx polarized melanin lenses from Vision-Ease Lens, Inc. Blue light is actually high-energy visible light (HEV) that research has found may contribute to development of age-related macular degeneration. Most sunglasses offer little or no protection against blue light.” All About Vision: Sunglasses: What's New in Sunglasses
