Patient Education

Lutein


What is it? Lutein is a type of organic pigment called a carotenoid. It is related to beta-carotene and vitamin A. Many people think of lutein as "the eye vitamin."

Lutein is one of two major carotenoids found in the human eye (macula and retina). It is thought to function as a light filter, protecting the eye tissues from sunlight damage. Foods rich in lutein include egg yolks, spinach, kale, corn, orange pepper, kiwi fruit, grapes, zucchini, and squash.

Lutein is commonly taken by mouth to prevent eye diseases, including cataracts and a disease that leads to vision loss in older adults (age-related macular degeneration or AMD). Lutein is used for many other conditions, but there is no good scientific evidence to support these other uses.
