The role of lutein
 Lutein is an important antioxidant for the carotenoid family (a group of plants found in the natural fat-soluble pigments) and a, also known as "plant progesterone" in nature co-exist with zeaxanthin .
 (1) the main pigment components of the retina: lutein and zeaxanthin form of vegetables, fruits, flowers and other major components of plant pigments, but also human retinal macular region * the main pigment. The human eye contains high levels of lutein, this element is the human body can not manufacture and must rely on to supplement the intake of lutein, if the lack of such elements, the eye will be blind.
 (2) protect your eyes from light damage, slow aging and prevent eye disease: the suns ultraviolet rays and blue light entering the eye will produce a large number of free radicals, leading to cataracts, macular degeneration and even cancer. UV lens and cornea normally be filtered out, but Blu-ray has to penetrate the eye directly to the retina and macula, lutein in the macula are able to filter out blue light, blue light to avoid damage to the eyes. Macular area of the outer layer of fat are particularly vulnerable to oxidative damage of sunlight, so this area prone to degradation.
 (3) antioxidant, helps prevent the body caused by aging cardiovascular sclerosis, coronary heart disease and cancer diseases.

 (4) protection of eyesight: Lutein acts as an antioxidant and protective effect of light, can promote retinal cells rhodopsin (Rhodopsin) re-generation, can prevent severe myopia and retinal detachment, and can improve vision, protect eyesight. Particularly suitable for students, drivers, and human consumption.
 (5) to alleviate the symptoms of fatigue; (blurred vision, dry eye, eye swelling, eye pain, photophobia, etc.)

 (6) increase macular pigment density, protect the macula, macular promote development;

 (7) the prevention of macular degeneration and retinitis pigmentosa;

 (8) to reduce the generation of drusen to prevent the occurrence of AMD;
