Application:

1. A major component of retinal pigment: lutein and zeaxanthin constitutes a major component of vegetables, fruits, flowers and other plant pigments, as well as the human eye macular area main pigment. The human eye contains high levels of lutein, this element can not be manufactured by the body and must be supplemented by the intake of lutein, if the lack of such elements, the eyes will be blind;  

2. protect the eyes from light damage, slow aging and prevent diseases of the eye: the sun's ultraviolet radiation and blue light entering the eye will produce a lot of free radicals, leading to cataracts, macular degeneration, and even cancer. General cornea and lens UV filter can, but they can penetrate the eye directly to Blu-ray and macular retina, macular lutein is able to filter out blue light, blue light to avoid damage to the eyes. Fat outer macular are particularly vulnerable to oxidative damage of sunlight, so this area prone to degradation.
