In particular, lutein is known to improve or even prevent age-related macular disease which is the leading cause of blindness and vision impairment. Zeaxanthin along with Lutein are important nutrients found in green leafy vegetables, as well as other foods, such as eggs. Many studies show that lutein and zeaxanthin reduce the risk of chronic eye diseases, including age-related macular degeneration and cataracts. Anthocyanin-rich bilberry extract has a protective effect on visual function during retinal inflammation. it is believed to improve night vision, for which clinical trials have been performed. Cataract and glaucoma are also thought to be prevented by this extract. Lycopene may prevent or delay the formation of cataracts and reduce your risk of macular degeneration, the leading cause of blindness in older adults. Citrus bioflavonoids contain high amounts of anthocyanins — flavonoid pigments that are powerful antioxidants. Anthocyanins may help reduce the risk of cataracts and macular degeneration and help maintain the health of the cornea and blood vessels in various parts of the eye. Pine Bark extract helps to reduce higher pressure in eyes and improve overall ocular health. Betacarotene is most important pro-vitamin A, from vegetable source carrot.  Cumulative effect of oxidative stress damaging eye cells is believed to be prevented and repaired by Batacarotene. The mechanism by which α-lipoic acid inhibits retinopathy possibly involves inhibition of both oxidative damage to DNA and nitrative stress in the retina. Thus, supplementation with α-lipoic acid represents an achievable adjunct therapy to help prevent loss of vision in diabetic patients. Diet high in thiamine reduces your risk of developing cataracts by 40%. As an antioxidant, riboflavin has the potential to reduce oxidative stress in body, including eyes. Researchers have also studied several B vitamins for their impact on eye health, particularly vitamins B6, B9 and B12. This combination of vitamins can lower levels of homocysteine, a protein in your body that may be associated with inflammation and an increased risk of developing AMD. Vitamin C is required to make collagen, a protein that provides structure to eye, particularly in the cornea and sclera. Vitamin E is a potent antioxidant that helps protect your cells — including your eye cells — from damage by free radicals, which are harmful, unstable molecules. Vitamin B And Folic Acid May Reduce Risk Of Age-related Vision Loss. Elemental Zinc, Selenium, chromium, Iron and copper are essential trace elements, which are required in body and eye to prevent damages to the cells due to their antioxidative properties. These are eye health supplement can be easily consumed as a supplement. A healthy level of these trace elements in the body helps maintain balanced intraocular pressure in the eyes.
