Quite a few scientific studies over the years have shown that the antioxidant vitamins (vitamins A, C, and E) may play a role in reducing the risk of developing glaucoma, cataracts, and macular degeneration.
Some newer studies have focused on carotenoids (a type of antioxidant) and their link to eye health. The findings suggest that people who eat diets rich in two of these carotenoids—lutein and zeaxanthin—may have a lower risk of developing age-related macular degeneration (AMD), a condition that can lead to vision loss.
One important study showed that high quantities of vitamins A, C, E, beta-carotene, and minerals such as zinc and copper could slow the progress of AMD. The problem is that the amounts needed to have an effect are much higher than most people get from their diets. While the simple solution might seem to be taking supplements, that might not be the best answer for some people. Such high doses of vitamins and minerals can have other affects on the body, not all of them good.
If you are considering taking supplements for eye health, talk with your doctor or Sobeys Pharmacist first. A health professional can advise you on which supplements would be right for your personal health condition.
