Supports healthy vision in ageing Supports a protective macular pigment May help protect the macular region of the eye from free radical damage. Contains omega-3 fatty acids important for eye health. A percentage of the sales from Lutein-Vision Advanced supports Macular Degeneration New Zealand. Lutein and zeaxanthin Lutein and zeaxanthin are carotenoids found in the human eye. The highest concentration is found in the macular area of the retina. The macula is responsible for central vision. Our ability to recognise faces, read, drive, see colours and contrast are all dependent on a healthy macula. In the macula, lutein and zeaxanthin support a natural layer of yellow pigment called the macular pigment. This pigment serves as an effective natural filter of the most damaging light (near-to-UV blue light) that reaches the retina. A dense macular pigment is more protective than one of low density. In addition to supporting pigment density, lutein and zeaxanthin function as antioxidants, helping to protect a healthy retina and lens of the eye. Selenium Lutein-Vision Advanced contains selenium as selenomethionine, an easily absorbed form of selenium. Selenium plays an important role in the bodys antioxidant system. Omega-3 fatty acids Several studies have found that higher intakes of omega-3 fatty acids and fish are associated with good eye health. Very high levels of polyunsaturated fatty acids, particularly DHA (docosahexaenoic acid), are present in the retina, specifically in photoreceptor cells and the vascular part of the retina. The photoreceptors are constantly being renewed and therefore a constant supply of DHA may be required for proper retinal function.
