What you need to know about Eye Health
Eye health supplements have some of the strongest clinical evidence in the supplement world — particularly for age-related macular degeneration. The AREDS2 trial established a high evidence bar that we use as our reference point.
Every review in this category cites primary literature. We do not accept payment from brands in this space and our scores are never adjusted based on affiliate commission rates.
Key ingredients — what the evidence shows
These are the most commonly included ingredients in eye health supplements. The evidence summary reflects the current state of peer-reviewed human research, not manufacturer claims.
| Ingredient & Common Dose | Evidence Summary |
|---|---|
Lutein (10mg) + Zeaxanthin (2mg) | AREDS2-validated combination. Accumulates in the macula and filters damaging blue light. Best-evidenced eye supplement duo. |
Vitamin C (500mg) + Vitamin E (400 IU) | AREDS2 formula components. Antioxidant protection for retinal cells. Evidence strongest in those with moderate-to-advanced AMD. |
Omega-3 DHA (1000mg) | Major structural component of retinal cells. Strong observational data; RCT evidence for dry eye disease is consistent. |
Zinc (80mg oxide or 25mg picolinate) | AREDS2 included zinc at 80mg. Transports Vitamin A to retina. Lower doses (25mg) may have better safety profile long-term. |
Astaxanthin (6–12mg) | Emerging evidence for reducing eye fatigue and improving blood flow to the retina. Less evidence than AREDS2 nutrients but promising. |
