Our eyes work harder today than at any time in history, mostly due to artificial light sources and long hours in front of glaring screens. Our eyes need to be nourished with large amounts of antioxidants to help repair damage caused by overuse and accumulated exposure to solar radiation. Carotenoids are potent antioxidants found in high concentrations in eye tissue. Lutein, the most prevalent carotenoid in the eye is naturally deposited as a protective layer in the macula, a small spot in the back of the eye responsible for central vision. A healthy lutein layer shields the macula from damaging UV light and can improve our ability to react to bright flashes of light, to see more clearly in low light conditions and helps to reduce the risk of developing cataracts.
