It is estimated that half of Americans have poor eyesight . While poor eyesight is often a matter of genetics, it is still important that you take steps year-round to keep your eyes their healthiest. Protection and prevention are your best defenses against poor eyesight. Here are five ways you can take care of your eyes.
1. Get Plenty of Vitamin C, Omega-3s, and Zinc

High levels of caffeine can actually cause your eyes to dry out and become irritated, so it is possible to have too much of a good thing.
4. Give Your Eyes a Break
When you are reading, make sure that whatever you are reading is at least an arm’s distance away. When working in front of a computer screen, rest your eyes every 20 minutes by looking 20 feet away for at least 20 seconds. This exercise is called the 20-20-20 rule . When we are reading or staring, we do not blink as often as usual, so make sure that you blink while looking at a book or a computer screen. Blinking is how new tears are brought to the surface, which helps to keep your eyes moist.
