We've heard that tomatoes can help your skin, that Mediterranean food is good for your heart, and that a little agave nectar won't hurt your libido. But what about our eyes?

Kale and Spinach

Just one cup of these cooked vegetables contains more than 20 mg of lutein and zeaxanthin -- two nutrients that are good for your eyes. These nutrients have been shown to reduce the risk of age-related macular degeneration and cataracts. Other sources include kale, turnip greens, corn, green beans, broccoli, romaine lettuce, and green beans.

oranges and eggs

That last slide might be hard to swallow if you don't like leafy greens. Fortunately, eggs and oranges are also good sources of lutein and zeaxanthin. So expect thanks in your eyes after every breakfast of eggs and OJ.

nuts and seeds

Vitamin E protects the cells in our eyes from free radical damage and slows the progression of cataracts and age-related macular formation. You can get more than one-third of your daily value for vitamin E in just one ounce of sunflower seeds or almonds. Wheat germ, hazelnuts, and peanut butter are also good sources of the vitamin.

And of course carrots

Phew, we mentioned carrots! Yes, these veggies help your eyes by providing beta-carotene that enhances night vision. But you don't need a rabbit's appetite to treat your eyes.

We can use Meta Hunter (which has the Foods database) to find more foods that are good for our eyes. It also finds more foods that are good for our other organs.
