Is it possible for me to keep my eyes healthy?

Sunglasses. Just like your skin, protect your eyes from the harsh glare of the sun. Get some with uva and uvb protection! but probably the biggest thing you can do is have a healthy diet and exercise. Any guesses on one of the leading causes of blindess in the u.S? Diabetic eye disease - things like diabetic retinopathy. So keep your body healthy, including your eyes!
Healthy eyes. Regular eye exams, good diet, daily multivitamin, avoid smoking tobacco, ultraviolet blocking sunglasses, protective eyewear when needed = healthy eyes.
