10 Tips to Protect Your Eyes

by Marin Gazzaniga for MSN Health & Fitness

We go to the gym, abstain from chocolate cake and drink gallons of water all in the name of good health. But what can we do to protect those most valuable organs—our eyes? We talked to ophthalmology experts to find out what we should be doing to preserve the oft-neglected eyes.

“Eyes are delicate and precious,” says Dr. Andrew Iwach, spokesperson for the American Academy of Ophthalmology (AAO). “Just a touch of maintenance will keep them going for years.”

1. Regular checkups. When was the last time you had an eye exam? If it was age 3, chances are you’re due. The AAO recommends an eye exam before age 5 to check for childhood problems like lazy eye or crossed eyes, and then on an as-needed basis (vision problems or injuries) up to age 19. One exam in your 20s, and two in your 30s can catch problems for early treatment. It’s normal for vision to change with age, plus serious eye problems like glaucoma and macular degeneration (deterioration of retina that causes loss of detail vision) can be treated if detected early. So step up the eye exams when you hit 40 to every two to four years; after 65, every one to two years. Anyone with diabetes, with a family history of eye problems or African-Americans over 40 should check with their doctor about more frequent visits. (In middle age, African-Americans may need more frequent checkups because of an increased risk for glaucoma.)

2. SPF for the eyes. Sunglasses don’t just prevent crows’ feet from squinting, they also block harmful ultraviolet and other rays than can play a role in cataracts and macular degeneration. Fair-skinned Caucasians are at the greatest risk for the latter. Be sure your sunglasses have 100 percent UV protection. “The blue wavelengths--violet and blue--hit the retina,” says Dr. Lylas Mogk, co-author of Macular Degeneration: The Complete Guide to Saving and Maximizing Your Sight. “The best filters against blue are in the amber-orange-brown range of commercial sunglasses.” You should always wear sunglasses when outside (and not just in the summer) but especially in high glare areas like snow or water. A wide-brimmed hat is great for blocking rays—even if it counteracts the cool of your aviators.

3. Eye protection. Sunglasses aren’t the only protective eyewear you should don. Obviously anyone working around construction, manufacturing—any job with machinery and flying particles—must wear eye protection. But even when you’re working around the house, you should guard your eyes. “Hanging a picture, plaster or even a nail can fly into your eye,” warns Dr. Iwach. Any hardware store sells inexpensive clear plastic eye protection.

4. Contact care. “Contacts are a great tool but they come with responsibility,” says Dr. Iwach. Be sure to have a pair of glasses with a recent prescription so that if you get any irritation you can change over. Wearing your contacts when your eyes are irritated can turn a simple problem (irritation) into a significant problem (ulcers). Make sure you care for the lenses properly. “I can’t believe people who pop a lens in their mouth and then put it in their eye. That is not a good idea unless you want to be seeing the eye doctor a lot,” warns Dr. Iwach. Make sure your solutions aren’t expired, keep your contacts clean—and don’t suck on them.

5. Eye candy. Are carrots really good for your eyes? “Carrots are rich in vitamin A, which the retina needs,” says Dr. Lylas Mogk. “But we’re not in the least bit in danger of having vitamin A deficiencies.” However, green leafy veggies like kale, collard and mustard greens, and spinach are good for the eyes because they contain lutein, which studies indicate can reverse symptoms of macular degeneration. And getting plenty of omega-3 fatty acids from fish and flax can help prevent dry eyes. But avoid omega-6 fatty acids, which is tricky in the American diet. Omega-6s are in vegetable oils. “There are very few processed or packaged foods that don’t have vegetable oils,” notes Dr. Mogk. “And the omega-6s counteract the good omega-3s.”

6. Eye lube. Our eyes get dryer as we age. “The biggest reason people have dry eyes is that the tear film doesn’t have the right consistency of water, mucus and oil,” says Dr. Mogk. The oil part of your tears comes from little glands around your eyelids. As you blink, oil is supposed to coat the eyes. But if you don’t have a good eye slick, the tear film evaporates and eyes feel dry. This triggers extra tear glands, which is why your eyes tear up when they get dry and irritated. Omega-3 helps with this. Also, heat and air conditioning can cause dry eyes, especially if you sit near a vent or fan unit. Make sure your car’s vent isn’t blowing toward your face.

7. Quit smoking. Need another reason to quit smoking? You got it: Smoking increases the risk and accelerates the development of cataracts, macular degeneration and optic nerve damage. “I’d be more afraid of losing your vision than lung cancer,” says Dr. Iwach.

8. Eye strain. Any focused work means you don’t blink as frequently. And all the computer work and Internet surfing can take a toll. It’s always good to take a break, change focus. And artificial tears can help with eyestrain, lubricating the eyes to help you work longer.

9. Talk to your family. Eye problems are often hereditary. If you are diagnosed with glaucoma or another eye condition, share that information with your immediate and extended family. “It’s a way to give the gift of vision for the rest of their life,” notes Dr. Iwach. The sooner people are diagnosed, the more that can be done to treat and prevent further damage.

10. Stay healthy. We’ve already seen how eating right (veggies over processed foods) helps with eye health. Exercise increases circulation, which can lower pressure on the eyes, which helps with those who have glaucoma. Getting regular overall physicals may lead to early detection of diseases like diabetes or other systemic conditions that can lead to eye problems. And most important, if something bothers you or feels wrong, get it checked out. As Dr. Iwach puts it, “You get your oil checked regularly, so get your eyes checked regularly.”

Beauty lies in eyes

Eye is a very sensitive organ. Today many of us spend long hours sitting in front of a PC or laptop. Using these gadgets actually strains our eye muscles and causes dryness. Besides, pollution, diseases like diabetes, sinusitis and thyroid can also effect the eyesight. If you are suffering from redness of the eye continuous headaches, blurred vision eye fatigue, the urge to keep your eyes closed, itching in the eyes, spots and strings floating in your field of vision , then you need to get your checked immediately.

Exercise:
Eye exercises help in keeping the six eye muscle, which help the eyes to rotate, flexible and strong If the muscle become stiff, it becomes painful to move the eyes and close the lid. Exercising also helps to relieve the pressure on the optic nerve that transmits information from the eye to the brain. Remember if the optic nerve is damaged, it cannot be repaired.

Here are a few eye exercises that will help your eyes to relax. Most importantly, you can do anywhere.

Eye Massage:
Close your eyes tightly for 5 to 6 seconds and quickly open them. Repeat this for at least 7 to 8 times.
Close your eyes and massage them with the tip of your third finger (ring finger) in circular movements.
Close your eyes. Place three fingers of your hand on your upper eye lids, apply a little pressure and hold for 1-2 seconds, then release. Repeat at least 5 times.

Eye Movement:
This exercise is recommended to people who generally sit for long hours in front of the computer.
Sit and be relaxed. Now roll your eyes first in clockwise direction and then in anticlockwise direction. Once a circle of movement is completed blink your eyes to rest the eyes. Repeat this at least 5-6 times

Clock Exercise:
Imagine yourself standing in front of a really big clock. Now imagine looking at the middle of the clock. Slowly look at any hour mark and that too without turning your head. Then look back at the centre and look at another hour mark. Do this at least 10 to 12 times. This exercise is also beneficial if done with closed eyes.

Focus A Mark:
Sit Near a window and keep a distance of about 50 cm from the window. Make a mark on the glass of the window with a small sticker or a felt pen at your eye level. Look or focus on something far away for 10 - 15 seconds through this mark and then return back to the focus.

Scribble On Wall:
Stand in front of a wall and pretend that you are writing with your eyes, without turning your head. This is very good exercise, which might seem difficult in the beginning but slowly you will enjoy it. Remember the bigger the letters, the better the effect.

Blink Exercise:
Blinking is not actually an exercise but it is very important. Starting at an object uninterrupted for a long time also causes strain and this should be also avoided. So make a rule to blink often.

Good to remember:

  • Have a diet that is loaded with beta-caretene, a vitamin especially helpful in maintaining healthy eyes. Fruits and veggies like carrot are rich in beta-carotene.
  • Contact lenses should never be worn for more than 12 hours. Wearing contacts for long cannot only cause extreme uneasiness, but permanent sight damage.
  • Place cold cucumber slices or tea bags soaked in cold water and press gently for 10 minutes before going to bed. This pacifies your eyes and also prevents puffiness.
  • Always wear UV protective sunglasses while getting out in the sun.
