Nutritional supplements cannot prevent AMD. However, the AREDS/AREDS2 supplements may delay progression of intermediate to advanced AMD and may help you keep your vision longer.

After these manipulations, the data seemed to show that the drug prevented what they called “AMD events”, but it did so for only in one group of patients, the one who had intermediate AMD in one eye, and advanced AMD in the other. The study did NOT show that these patients had any vision benefit from taking this drug.

PreserVision AREDS 2 contains high levels of a specific combination of vitamins and minerals recommended by the NEI to help reduce the risk of progression of moderate-to-advanced AMD.

Vitamin A Vitamin A is essential for good vision. It is a component of the protein rhodopsin, which allows the eye to see in low-light conditions.

Vitamin A Vitamin A is an antioxidant that protects the cornea and retina. It's also crucial for night vision - vitamin A is necessary for producing protective eye pigments. Carrots are considered good for eye health because they're high in beta carotene (vitamin A).
