Zeaxanthin

The macular pigment of the eye is rich in carotenoids, primarily Lutein and Zeaxanthin. In fact macular pigment is mostly Lutein and Zeaxanthin, two substances that act as antioxidants. This means that they fight free radicals. By increasing dietary intake of Zeaxanthin combined with Lutein you may minimize the risk of developing age-related macular degeneration. It seems that adding these specific nutrients to your meals may not only sidestep macular damage by free radicals, but also strengthen macular tissue.
