Summary
Lutein is a carotenoid structure similar to Zeaxanthin, and the two are components of many food products such as egg yolks and paprika. Lutein may bioaccumulate in the eyes where it is thought to reduce oxidative stress.
Lutein, as well as the related zeaxanthin, are carotenoid structures similar to pre-vitamin A (β-carotene) and involved in eye health. A dietary component of eggs, lutein appears to be effective for this claim and a general antioxidant.
