Vision Supplements in Multivitamins
Before you ask your doctor about taking mega-doses of vision supplements, take a look at your multivitamin, if you use one. You’ll probably find you’re already taking several of the following nutrients for healthy eyes. If not, look for these nutrients. Listed next to them are the recommended dietary allowance (RDA) for each

Vitamin C: men – 90 mg, women – 70 mg (85 mg during pregnancy and 120 mg when breast-feeding)
Vitamin E: 15 mg for teens and adults (15 mg for women during pregnancy and 19 mg when breast-feeding).
Beta-carotene: None
Zinc: men – 11 mg; women – 8 mg (11 mg during pregnancy and 12 mg when breast-feeding).
Zeaxanthin: None
Selenium: 55 mcg for teens and adults (60 mcg for women during pregnancy and 70 mcg when breast-feeding).
Lutein: None
Calcium: 1000 mg- men and women : 1200 mg- women over 51 and men over 71
Thiamin: men – 1.2 mg, women – 1.1 mg. (1.4 mg if pregnant or nursing)
Folic acid: Adult: 400 mcg Dietary Folate Equivalents (600 mcg DFE is pregnant, 500 mcg DFE if breat feeding)
Omega-3 essential fatty acids (including flaxseed oil): None; but for cardiovascular benefits, the American Heart Association recommends approximately 1,000 mg daily.
If you can’t find a single product that contains all or most of these nutrients, they are available individually.

Should You Take High Doses of Vision Supplements?
For people with or at risk for some eye conditions, high-dose vision supplements may help slow or prevent these conditions.

For example, the National Eye Institute released the findings of its Age-Related Eye Disease Study (AREDS). The results showed that high doses of antioxidants vitamin C (500 mg), vitamin E (400 IU), and beta-carotene (15 mg/25,000 IU), along with zinc (8 mg), reduced the risk of vision loss from advanced age-related macular degeneration (AMD) in some, but not all, people with this disease. The only patients who benefited were those with:

Intermediate AMD or
Advanced AMD in just one eye
Ask your doctor if you’re in one of those categories.

However, the ingredients of vision supplements may change with the completion of the AREDS2 study. This study sought to see if adding other vitamins and mineral to the supplement would improve results of the AREDS. The first addition was omega-3 fatty acids (fish oil), and the second was a combination of two carotenoids, lutein and zeaxanthin, which are found in leafy green vegetables and highly colored fruits and vegetables. The research showed:

Beta-carotene did not lower the risk of progression of AMD.
Adding omega-3 to the AREDS formula did not lower the risk of progression of AMD.
The AREDS formula was still found to be protective with less zinc added.
People who took a formula with lutein and zeaxanthin (and who may not have been taking enough in their diet) showed further improvement with the new AREDS formula.
In general, people who took lutein and zeaxanthin instead of beta-carotene had more of a benefit.
