But what about makes foods good for your vision?

Antioxidants known as carotenoids represent one of the most widespread groups of naturally occurring pigments that can help your eyes. And among cartenoids, the most beneficial for eye health is lutein and zeaxanthin.

You can get your daily dose of both  from the best source: leafy greens. Greens, such as spinach, kale, peas, zucchini and broccoli are the richest food. Yellow pigmented fruits and vegetables, such as orange peppers, corn, oranges and honeydew melon are also great sources of these eye-protecting carotenoids.

Aside from fruits and vegetables, egg yolks are also high in lutein and zeaxanthin, which help protect the retina and filter the eye-damaging components of sunlight, according to the Journal of Food Science.

“The thinking is that our eyes age just like other parts of our body, and things like these substances can really make a big difference in preventing things like macular degeneration and cataracts.”

While experts know lutein and zeaxanthin are important to eye health, there are still questions about the best way to get them. Supplements may not have the same effect as naturally-occurring nutrients in fruits and vegetables. Also, there are no precise guidelines for how much lutein is needed for prevention of cataracts and macular degeneration.

It’s probably best to eat a lot of colorful fruits and vegetables.
