Broccoli contains lutein and zeaxanthin

A half cup of cooked Swiss chard provides a huge amount of both lutein and zeaxanthin, supplying 10 mg each. These plant chemicals, known as carotenoids, protect your retinas from the damage of aging, according to Harvard researchers. That's because both nutrients, which are actually pigments, appear to accumulate in your retinas, where they absorb the type of shortwave light rays that can damage your eyes. So the more lutein and zeaxanthin you eat, the better your internal eye protection will be.
