Eye diseases such as macular degeneration can result in damage to the eye and vision loss. Many eye conditions are not curable, so prevention often provides the best effort in retaining good vision. Certain nutrients provide protection against eye diseases, and, in the case of dry eye, may help relieve symptoms. Knowing the nutrients that promote healthy eyes may help you and your doctor determine the right supplements for your eyes.
AREDS
The National Eye Institute conducted a study called the Age-Related Eye Disease Study, or AREDS, and released the findings in 2001. Research determined that you can prevent your risk of macular degeneration by 25 percent if you take high doses of certain nutrients. The daily dosage requirements consist of 25,000 International Units, or IU, of vitamin A, 500 mg of vitamin C, 400 IU of vitamin E, as well as 80 mg of zinc. High doses of zinc could lead to a copper deficiency, so the study recommends including 2 mg of copper.
Omega-3
Omega-3 fatty acids aid in human growth and development, and these essential acids may also help prevent macular degeneration and the irritation and discomfort caused by dry eye syndrome. Your body does not produce omega-3, and you must consume omega-3 through diet or supplements. Foods that contain omega-3 include fatty fish such as mackerel, tuna and salmon, as well as walnuts and ground flaxseed. However, using fish oil capsules or flaxseed oil capsules will provide a consistent daily intake.
Lutein
Lutein is a pigment that you can find in many brightly colored fruits and vegetables. The antioxidant properties of lutein may help slow down the growth of cataracts and prevent macular degeneration. According to a Harvard study by Dr. Johanna M. Seddon and her associates, an intake of 6 mg of lutein may significantly reduce your likelihood of macular degeneration.
Formulations
After the National Eye Institute released the findings of the Age-Related Eye Disease Study, many supplement manufacturers created formulations based on the studied nutrients and their doses. Many of these supplements also contain lutein. You should read the labels of supplements to ensure that the supplements will provide you with the necessary dosage amounts.
Considerations
Prior to changing or adding supplements, you should discuss these nutrients with your doctor. She can help you determine a dose that is appropriate and that will not interfere with any medications or treatment of health conditions you may have.
