Eggs contain the omega-3 fatty acid DHA and are the most readily available source of lutein and zeaxanthin. An egg per day for most people, unless you have diabetes, is excellent eye food. Diabetics need to ask their doctor whether eggs can be a part of their diet.
Avocados are one the most nutrient-rich fruits we eat, so it's no wonder they're great for eyes. They contain lutein and help prevent macular degeneration and cataracts. "They're also a great source of other important eye nutrients such as beta-carotene, vitamin C, vitamin B6 and vitamin E," Gerbstadt says. Those vitamins place avocados among the top-10 eye foods.
