Carotenoids, antioxidants present in fruits and vegetables, are colorful. Like lycopene and beta carotene, lutein and zeaxanthin protect the eyes from oxidative stress. The macula and retina contain lutein, zeaxanthin, and meso-zeaxanthin, which filter blue light and promote eye health. Brain health research includes lutein and zeaxanthin.

Fish oil for your heart and joints may also help your eyes. Nearly 80% of Australian and New Zealand optometrists advocated omega-3 fatty acid diet for eye health, and over 60% recommended supplementation. Omega-3s are still explored for eye health.
Zinc, another antioxidant, has been examined for eye health for decades because it transports vitamin A to the retina. Zinc is a wonderful mineral supplement since it improves immunological, cardiovascular, neurological, and visual health as you age.
Delphinidins are abundant in Chilean wineberries, or maqui berries. These substances help the eye's natural defenses, comfort, and tear production. They also shield healthy eyes from oxidative stress.
