Lutein is a carotenoid pigment found in high concentrations in the macula of the human eye, where it plays a crucial role in protecting against oxidative stress and blue light damage. It is also present in various fruits and vegetables, particularly dark green leafy ones.
Lutein absorbs high-energy blue light, reducing phototoxic damage to the retina.
Lutein neutralizes reactive oxygen species, protecting retinal cells from oxidative stress.
By filtering blue light and reducing oxidative stress, lutein helps prevent or slow the progression of AMD.
Lutein's antioxidant properties may reduce lens oxidation, potentially lowering cataract risk.
