    Good nutrition, particularly through the consumption of leafy greens and colorful fruits and vegetables, supports overall eye health and may lower the risk of dry eye. Additionally, dietary patterns that are beneficial for heart health can also promote eye health by ensuring proper blood flow to the eyes.

    Good nutrition helps to keep the eye healthy overall and may reduce the risk of eye diseases such as dry eye. Overall, getting plenty of leafy green vegetables along with yellow, orange, and other colorful fruits and vegetables will help to keep the eyes healthy.[1]

    Dietary patterns that are good for the heart may also be good for the eyes, since the eyes rely on tiny arteries to deliver oxygen and nutrients. As with the heart, keeping blood vessels healthy will help to keep the eyes healthy.
