| Lutein + zeaxanthin | Macular health | Moderate | Part of the AREDS2 formula. |
| Omega-3 for dry eye | Dry eye | Insufficient | A large NIH-funded trial found no benefit over placebo. |
| Bilberry | Night vision | Insufficient | No good human evidence. |
Ratings follow our evidence scale and are updated as new research appears.
Claims to be careful with. Supplements can't restore lost vision, cure glaucoma or cataracts, or replace glasses. Claims of "20/20 vision naturally" go far beyond the research.
See a doctor if…
You have sudden vision loss, flashes of light, a curtain over your vision or eye pain (get urgent care), or haven't had an eye exam in over two years.
