By definition, a cataract is a clouding of the normally clear lens of your eye. Cataracts plague over 20 million Americans above age 40 and 50%percent of adults over 80. Traditionally, Vitamin E has been the predominant nutrient used to relieve stress from eye cells and protect against cataracts. In recent times, however, studies have indicated that the powerful antioxidants lutein and zeaxanthin are also helpful in protecting eyes from developing cataracts.
Lutein and zeaxanthin are carotenoids, which are pigments that the body can turn into Vitamin A. Carotenoids, primarily found in vegetables, have traditionally been known to act as antioxidants and promote a healthy immune system. Lutein and zeaxanthin are also the only carotenoids actually found in the lens of the eye.
In numerous clinical studies, participants who consumed the greatest amounts of lutein and zeaxanthin have been found to have an 18% lower risk of developing cataracts. The carotenoids showed that they protected the eye from normal oxidative stress that causes cataract growth.
In another study, eye cells were exposed to different nutrients. After the designated 30 day period, the cells exposed to a lutein and zeaxanthin combination had not been damaged at all. The other untreated cells showed normal deterioration. When the lens in the eye breaks down, cataracts form.
Although nutrition and medication will not cause cataracts to recede, nutrients such as lutein and zeaxanthin can help reduce the risk of cataract damage. Most people don’t get enough lutein and zeaxanthin from diet alone, so supplementation is recommended.
