Avocados contain two vital carotenoids—lutein and zeaxanthin. Daily activities create free radicals, so carotenoids act as antioxidants to remove them. Lutein and zeaxanthin are both essential for eye health. They work well alone, but even better together. They are the only carotenoids found in the macula, which is key for vision. Studies show strong links to macular degeneration and cataract formation.
