Vitamins for the eyes -- recommended

 Yesterday my ophthalmologist, Dr. Rogers, suggested I could benefit from vitamins to slow the progress of macular degeneration. The study is called AREDS 2, so I've looked through a few articles that explain it and which are free to download and print.

Abstract Is There an Optimal Combination of AREDS2 Antioxidants Zeaxanthin, Vitamin E and Vitamin C on Light-Induced Toxicity of Vitamin A Aldehyde to the Retina? - PubMed (

"Vitamins C and E and zeaxanthin are components of a supplement tested in a large clinical trial-Age-Related Eye Disease Study 2 (AREDS2)-and it has been demonstrated that they can inhibit the progression of age-related macular degeneration. The aim of this study was to determine the optimal combinations of these antioxidants to prevent the phototoxicity mediated by vitamin A aldehyde (ATR), which can accumulate in photoreceptor outer segments (POS) upon exposure to light."

Abstract The Age-Related Eye Disease Study 2 (AREDS2): Study Design and Baseline Characteristics (AREDS2 Report Number 1) - PMC (


The Age-Related Eye Disease Study (AREDS) demonstrated beneficial effects of oral supplementation with antioxidant vitamins and minerals on the development of advanced age-related macular degeneration (AMD) in persons with at least intermediate AMD (bilateral large drusen with or without pigment changes). Observational data suggest that other oral nutrient supplements might further reduce the risk of progression to advanced AMD.

The primary purpose of Age-Related Eye Disease Study 2 (AREDS2) is to evaluate the efficacy and safety of lutein+zeaxanthin (L+Z) and/or omega-3 long-chain polyunsaturated fatty acid (LCPUFA) supplementation in reducing the risk of developing advanced AMD. The study will also assess the reduction in zinc and the omission of beta-carotene from original AREDS formulation.
