Simply the act of letting light pass through the eye and hit the retina increases the exposure of eye tissue to a range of different light-generated free radicals. For this reason, it makes sense to optimize intake of all eye nourishing nutrients every day, especially as we age. Lutein is a carotenoid whose job it is to protect the retina from the free radical damage it undergoes constantly. Does optimizing lutein intake throughout life protect the retina as we age? Conclusive prospective studies have yet to be performed that can definitively answer this question, but population studies are suggestive of benefit. The lutein used in OcuForce™ is naturally derived from marigolds, not synthetically created in a chemical plant. Designs for Health never uses synthetic carotenoids in its products. Natural carotenoids offer a superior spectrum of benefits.
Carotenoids
Carotenoids not only ward off cataracts, but they also lower the risk of macular degeneration by 57 percent. [8, 9]
Protects Vision
The retinas in our eyes contain the highest concentration of polyunsaturated fats of any cells in the body. These delicate fats need antioxidant protection provided by many nutrients, including taurine. A deficiency of taurine increases damage to the retinas of both animals and humans. [6] Taurine may offer benefit for those with macular degeneration, though clearly more research is needed. [7]
Improves Night Vision
Anthocyanosides, the flavonoid complex in bilberries, speed the regeneration of rhodopsin, the purple pigment that is used by the rods in the eye for night vision. [1, 2] While earlier trials suggested that taking bilberry could benefit people with night blindness [3, 4] more recent trials with healthy volunteers have found no effect of bilberry on night vision. [5]
Promotes Blood Flow and Capillary Strength
Anthocyanosides are potent antioxidants. [10] They support normal formation of connective tissue and strengthen capillaries in the body. Anthocyanosides may also improve capillary and venous blood flow. Bilberry may also prevent blood vessel thickening due to diabetes. [11] Bilberry protects cholesterol from oxidizing in vitro. [12] While this action is thought to help prevent atherosclerosis, no human trials have studied whether bilberry may be useful in the regard. |
