Lutein (10mg) and zeaxanthin (2mg) daily are the most evidence-backed eye supplements, shown to reduce AMD progression by 18% in the AREDS2 trial. Omega-3 fatty acids (1-2g EPA/DHA) support retinal health and dry eye symptoms. Vitamin A (700-900mcg RAE) is essential for night vision and corneal integrity.
Vision impairment affects over 12 million Americans aged 40 and older, with age-related macular degeneration (AMD) and cataracts being the most common causes. The landmark AREDS2 trial established that specific nutrient supplementation can slow progression of AMD, and additional research supports several supplements for overall eye health.
| # | Supplement | Typical Dose | Evidence |
|---|---|---|---|
| 1 | Lutein & Zeaxanthin | 10mg lutein + 2mg zeaxanthin daily | Strong |
| 2 | Omega-3 Fatty Acids (DHA) | 1-2g EPA/DHA daily | Moderate |
| 3 | Vitamin A | 700-900mcg RAE daily | Strong |

The most evidence-backed eye supplements are lutein (10mg) and zeaxanthin (2mg), which are the only carotenoids found in the macula and lens. The AREDS2 trial, one of the largest eye supplement studies ever conducted, showed this combination reduced AMD progression by 18%. Omega-3s (DHA especially) support retinal cell membranes, and vitamin A is essential for night vision.
While supplements cannot cure AMD, the AREDS2 trial demonstrated that a specific formula containing lutein (10mg), zeaxanthin (2mg), vitamin C (500mg), vitamin E (400 IU), zinc (80mg), and copper (2mg) slowed progression of intermediate AMD to advanced AMD. These supplements are recommended by ophthalmologists for patients at risk of or with early-stage AMD.
Yes. Lutein and zeaxanthin are macular pigments that filter harmful blue light and act as antioxidants in the retina. The AREDS2 trial involving 4,203 participants showed significant benefits. Additionally, observational studies consistently show higher dietary lutein intake is associated with lower risk of cataracts and AMD. Good food sources include kale, spinach, and egg yolks.
