Just as you wear a seat belt to protect yourself when you're in a car, it's a good idea to protect your eyes before something happens to them.

Wearing sunglasses is high on the list of ways you can care for your vision. Buy a pair of sunglasses with ultraviolet (UV) protection to use whenever you're in the sun. UV light causes long-term damage to the inner structures of the eye, but wearing sunglasses whenever you're in the sun can help prevent conditions such as cataracts and macular degeneration. A cataract is an eye condition in which the lens of the eye becomes clouded, impairing vision. Macular (pronounced: mah-kyuh-lur) degeneration is an eye disease in which the macula, a structure within the eye that allows you to see, gradually deteriorates, leading to decreased vision or blindness. (Need one more reason not to smoke? Smoking puts you at greater risk for developing macular degeneration.)

You can also care for your eyes by putting on protective eyewear whenever you play sports like racquetball or when you're doing projects in shop class or the science lab. It only takes a second for something to hit an unprotected eye and cause serious damage. And avoid being near fireworks that could explode and harm your eyes. Why take chances with your vision?

Although steering clear of fireworks probably seems like an obvious way to protect your eyes, you may not think about protecting them around the house. Yet something you might do every day — staring at a computer screen for a long time — can strain your eyes. That's because most people blink about 10 times per minute. But when you stare, your blink rate can go down to two or three times per minute. The best thing you can do is to blink more! It also helps to change your focus frequently. Look at something across the room for a few moments and then go back to looking at the computer screen.

If your eyes feel dry and irritated when you use the computer, use artificial tears. Don't use products that remove the red from your eyes, though, because they may contain a chemical that eliminates redness temporarily but actually makes your eyes look worse later.

You should take special care of your eyes if you have a medical condition such as diabetes or juvenile rheumatoid arthritis because these conditions put you at an increased risk of developing serious eye disease. Be sure to see your doctor at least once a year if you have any medical condition that can affect your eyes. Depending on your situation, your doctor may need to check your eyes as often as every 3 months.
