is a carotenoid pigment found in many green vegetables, and is usually derived from marigold flower petals. Researchers have found that adults who consume 6 mg of lutein daily show a significant decrease in their risk of developing macular degeneration of the eyes. Even normal-sighted people who take lutein supplements report reduced glare and sharper vision. This can be helpful for anyone exposed to brilliant sunlight or computer screens on a daily basis. ...

... In general, individuals who consume large quantities of the vegetables and fruits that contain lutein may be less likely to develop cataracts and age-related macular degeneration (AMD) than individuals with a lutein-poor diet. AMD results from the deterioration of the retina''s central section. Partial or total vision loss may occur. Lutein is one of the two most common pigments (coloring agents) in the retina. It is believed to block out blue light and to protect retinal tissue from being damaged by light. In older individuals, the layer of yellow pigment in the retina tends to become thinner, increasing the chance for AMD. Taking lutein may thicken the yellow layer. In addition, lutein acts as an antioxidant to protect the interior of the eyes from damage by oxygen free radicals, natural chemicals produced in the body. Although a recent very large observational study of humans failed to prove that lutein affected the development of glaucoma, some earlier evidence suggests that lutein may help prevent some types of glaucoma, as well. Further studies are being conducted to better understand lutein''s possible role in glaucoma. ...
