There are two very important carotenoids found in avocados - lutein and zeaxanthin. You create free radicals during everyday activities, so carotenoids act as antioxidants and remove them from your body. Lutein and zeaxanthin are both essential for eye health. Both of these carotenoids work well separately, but work even better together.
In the macula, which is essential for vision, these carotenoids are the only ones that gather. Macular degeneration and cataract formation are strongly connected, according to studies.
