To protect your eyes, eat a diet low in fats that are saturated or hydrogenated. Interestingly, unsaturated fats help scrub saturated fat-plaque from your blood vessels. So, a diet high in flaxseed oil and fish protects your eyes. Of course, smoking is a major problem. If you value your eyesight, don't smoke or be smoked on.
Sugar is also a culprit.
This list isn't very long, don't worry. But do limit the amount of sugar in your diet. For more information on having a healthy body and healthy eyes to go with it, visit our lean body page. We never reveal information about you to 3rd parties. See our privacy statement.
