What Is Macular Degeneration?Age-related macular degeneration (AMD) is a leading cause of vision loss in older adults. It affects the macula, the part of the retina responsible for sharp central vision. There are two forms: dry AMD, which is more common and progresses slowly, and wet AMD, which is less common but more aggressive. Wet AMD involves abnormal blood vessels growing under the retina that leak fluid and can cause rapid vision loss. Understanding the type and stage of AMD is essential because supplements are most helpful for certain stages.Key Nutrients and AREDS2The AREDS and AREDS2 studies, funded by the National Eye Institute, found that a specific combination of nutrients can slow the progression of intermediate AMD. The AREDS2 formula includes vitamin C, vitamin E, lutein, zeaxanthin, zinc, and copper. Lutein and zeaxanthin are carotenoids that concentrate in the macula and help filter blue light. The AREDS2 formula is preferred over the original because it replaced beta-carotene, which is linked to lung cancer risk in smokers. Supplements do not reverse vision loss, but they may reduce the risk of progression.Lifestyle, Safety, and Future DirectionsSupplements are only one part of AMD management. A healthy diet rich in leafy greens, eggs, and fish, along with not smoking, regular exercise, and blood pressure control, supports eye health. High-dose zinc can cause copper deficiency, and vitamin E may interact with blood thinners, so always talk to your doctor before starting AREDS2. The FDA has approved injectable drugs for geographic atrophy that slow progression, but they do not restore vision. Research into gene therapy and other approaches is ongoing.
Best Eye Health Supplements: How to ChooseChoosing the right eye health supplement starts with understanding your primary concern. For age-related macular degeneration (AMD), the AREDS2 formula—containing lutein, zeaxanthin, zinc, and vitamins C and E—has the strongest clinical backing. For dry eyes, omega-3 fatty acids (EPA and DHA) support tear film quality, while lutein and zeaxanthin may help filter blue light from screens. Our guide breaks down the science, ingredients, and dosages to help you make an informed choice.Top Eye Supplement Brands ComparedWe evaluated leading brands based on ingredient quality, formulation, and user feedback.

A balanced diet rich in leafy greens and fatty fish remains foundational to eye health.
