Most cataracts develop due to natural aging. As the eyes get older, vitamin C levels in the lens of the eye begin to decrease, increasing the severity of cataracts. Scientific studies have concluded that consuming at least 300 milligrams of vitamin C daily will help prevent the development of cataracts. A diet rich in vitamin C antioxidants, more so from food than supplements, has been attributed to slowly delaying the onset of cataracts along with delaying the worsening of cataracts.
Foods rich in vitamin C include cruciferous vegetables such as broccoli, brussels sprouts, cabbage, cauliflower and red and green peppers as well as citrus fruits like oranges, kiwi, lemon and grapefruit. White potatoes, strawberries, blackberries and tomatoes are also
excellent sources of vitamin C. Eye-friendly nutrients can also be found in sources of lutein, zeaxanthin, vitamin E and zinc.
Vitamin C helps protect the eyes against oxidative damage. Oxidative damage is a significant factor in the development of 2 types of cataracts: cortical and nuclear. Cortical cataracts develop on the edge of the lens while nuclear cataracts develop at the center of the lens. Vitamin C also counteracts against the effects of UV light damage. Oxidative stress and ultraviolet damage play a role in the development of age-related macular degeneration. Oxidative stress is the term for a harmful chemical reaction that takes place when cells consume oxygen and is considered a major contributor to age-related conditions including cataracts. It is well known that excessive UV exposure can be harmful to the skin, but many studies show that UV light can also increase the risk of cataracts and other eye conditions. Keeping the lenses clear and protected can limit damage that causes cataracts; increasing vitamin C intake can help maintain that level of antioxidant protection whereas low vitamin C may be related to cataract development.
