More than Meets the Eye

Lutein and zeaxanthin do more than give plants their pretty colors. These two compounds are found in large amounts in the lens and retina of our eyes.

Studies show that a diet that has sufficient amounts of lutein could help protect our eyes from damage in different ways, such as potentially helping prevent common eye diseases of macular degeneration and cataracts.
