One of the challenges we face as we age is the risk of degenerating eyesight. Three main types of eye problems can occur. The first is presbyopia, or farsightedness. This is where objects are hard to see close up and special glasses have to be prescribed, especially for reading. The second challenge is cataracts. One of the best ways to protect the eyes from cataracts is to simply use prescription sunglasses when outdoors in bright sunlight.
Additional measures to protect the eyes include introducing more fruits and vegetables into the diet. Antioxidants like selenium, vitamin C, Vitamin E and fish oil can also help reduce the oxidative stress produced by sun exposure. A third condition we see in aging is known as macular degeneration. In the case of macular degeneration, a part of the eye known as the macula, which is responsible for central vision, begins to degenerate leading to severe vision impairment.
Supplementation with lutein, along with antioxidants and fish oil, has also been found to be effective in the prevention of this disease. With a few simple changes in diet and lifestyle, we can do much to protect our eyes from degenerative diseases.
