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 (nih.gov)

"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 (nih.gov)

Purpose

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.

Five ways to protect your eyes from age-related macular degeneration

Age-related macular degeneration (AMD) is a condition in which the macula, the part of the eye that's responsible for your sharpest and most detailed vision, begins to thin and break down, causing vision loss. If left untreated, it can lead to blindness.

There is no surefire way to prevent AMD. However, there are things you can do to delay its onset or reduce its severity. Here's how:

  1. Smoking can speed up AMD damage. If you smoke, quit.

  2. Sunlight is thought to possibly promote AMD. Protect your eyes from the sun by wearing sunglasses and broad-brimmed hats.

  3. Research also suggests that certain nutrients help prevent macular degeneration. Eat a diet rich in fresh fruits and dark green leafy vegetables — such as spinach, collard greens, and kale — that are rich in lutein and zeaxanthin, which are key for eye health.

  4. For people at high risk of developing the advanced stages of the "wet" form of AMD, high-dose combinations of antioxidant vitamins and minerals may lower their risk by about 25%. However, supplements don't seem to help people who don't have AMD or who have early AMD.

  5. Ask your doctor about supplements if you have intermediate or advanced dry AMD or wet AMD. It's unclear whether omega-3 supplements are beneficial for AMD, but eating fish and other foods high in these nutrients may still be worthwhile for preserving optimal vision and overall good health.
