| March 2022 Many people turn to dietary supplements to prevent or slow the progression of certain eye diseases, such as cataract, age-related macular degeneration (AMD), glaucoma, and diabetic retinopathy. There is evidence that a combination of vitamins E and C, beta-carotene, and zinc (known as the AREDS formulation) may reduce the risk of developing advanced AMD. There is also some limited evidence that for less well-nourished populations, the carotenoids lutein/zeaxanthin may be associated with a reduction in progression to cataract surgery; however, whether supplementation would be beneficial for this population requires further study. Current data do not support dietary supplementation with vitamins A, C, and E for glaucoma or the use of cannabinoids for glaucoma treatment. More information about the AREDS formulation for AMD is available from the National Eye Institute. Readmore
