Overview

Zeaxanthin is a type of organic pigment called a carotenoid. It's related to vitamin A and found in the human eye (macula and retina) along with lutein.

Zeaxanthin is thought to function as a light filter, protecting the eye tissues from sunlight damage. Foods rich in zeaxanthin include eggs, oranges, grapes, corn, goji berries, mango, orange pepper, and some other vegetables and fruits.

People use zeaxanthin for age-related vision loss. It's also used for eye strain, mental decline, heart disease, breast cancer, cataracts, and many other conditions, but there's no good scientific evidence to support these uses.
