This document discusses the importance of dietary zeaxanthin for eye health. It notes that zeaxanthin is heavily concentrated in the macula of the retina, where it protects central vision and enhances vision. However, zeaxanthin is scarce in most people's diets, as it is found only in trace amounts in foods like eggs and corn. The document recommends obtaining 6-10 mg of zeaxanthin per day for optimal eye health, and reviews supplements that can help boost zeaxanthin intake.
