Lutein and zeaxanthin are dietary carotenoids that accumulate in the retina and human lens, particularly the macula region, which is located at the back of your eye.
The macula is essential for vision. Lutein and zeaxanthin are important antioxidants in this area, protecting your eyes from harmful free radicals. A 2020 research review found that neutralizing these free radicals over time can protect your retina from photo-damage.
