Diets that are rich in zeaxanthin appear to protect individuals from eye disease, especially those that develop with age, states WebMD. For example, as of 2015, studies show that people who eat foods with zeaxanthin, such as kale, broccoli and spinach, are up to 50 percent less likely to have cataracts.

It is easy to get this amount by eating the right foods. For instance, a single serving of broccoli, corn, greens, kale or spinach has enough zeaxanthin to positively affect eye health.Learn more about Vitamins & Supplements
