BLACKMORES Lutein Vision Plus 60S contains selenium as selenomethionine, an easily absorbed form of selenium. Selenium has an important antioxidant function in the eye as part of an antioxidant enzyme called glutathione peroxidase (GSH). GSH is concentrated in the lens where it has an important role in preserving the clarity of the lens and preserving healthy eye function.

Lutein and zeaxanthin are carotenoids naturally found in the human eye. The highest concentration is found in the macular area of the retina. They are also present in the lens. Supplements containing natural lutein and zeaxanthin esters have been shown in human trials to increase the density of the macular pigments.   Higher macular pigment density is associated with healthier eyes and the retention of youthful visual sensitivity.
