Eye care tips for computer users

11 Eye care tips for computer users
Most of our work is done on computers, and there is usually no escape from it. It is a visually intensive task and, unfortunately, our work pressure and lifestyles do not give us the opportunity to be kind to our eyes.
Which is why these tips should come in handy.
1. Know your eyes
Tears: The first line of defense, they also serve as lubrication by keeping the eyes moist and nourished; they also have a corrective lens function. Eyelids: Their main job is to protect your eyes from dirt, dust and harsh light.
Eyelashes: A protective net for your eyes.
Cornea: A refractive zone that guides light to reach the retina.
Pupil: Controls the amount of light that enters your eyes.
Lens: A refractive zone that also guides light into the retina.
Retina and Optic Nerve: A bunch of intricate wiring that carries vision signals between your brain and eyes.
2. Exercise your eyes
Dr Harish S Belvi, a practising ophthalmologist (eye specialist) based in Mumbai, says that regular work hours should be infused with short breaks. During such breaks, he suggests a small and easy exercise: "First, blink your eyes several times. While you keep your eyes closed, roll your eyeballs both clockwise and anticlockwise and take a deep breath. Gradually open your eyes while releasing your breath. This exercise lasts for a minute and you can repeat it three times before getting back to work." It serves as a good workout for the eyes.
3. Look away
While working for long hours, look at distant objects either in your office or outside. Looking at a distant object and then returning to your task helps your eyes focus better. Try taking such visual breaks for about five to 10 minutes every hour.
4. Positioning is everything
Correct positioning of your computer, keyboard and typing copy is essential. Your screen should be positioned about an arm¢s length from your eyes and 20 degrees below eye level. Consider foot and wrist rests for added comfort.
5. Lighting can make all the difference
Room lighting should be diffuse, not direct, to reduce glare and reflections from your screen. Look into an internal or external glare screen and be sure to set your color, contrast and brightness levels to suit you.
6. A little extra help for your glasses
Anti-reflective coatings on the lenses of your glasses can be applied by your optometrist to reduce discomfort and to ease reduced vision from bright and/or flickering light sources such as VDTs and fluorescent lights. And don¢t forget, your doctor of optometry can talk to you about eyeglasses designed specifically for people who use computers a lot.
Take time out, our 20-20-20 rule
Step I :-
After every 20 minutes of looking into the computer screen, turn your
head and try to look at any object placed at least 20 feet away. This
changes the focal length of your eyes, a must-do for the tired eyes.
Step II :-
Try and blink your eyes for 20 times in succession, to moisten them.
Step III :-
Time permitting of course, one should walk 20 paces after every 20 minutes
of sitting in one particular posture. Helps blood circulation for the entire body.
all in the blinking
Did you know that on average we blink 12 times per minute? But wait, did you know that when we¢re on the computer we only blink 5 times per minute? That can add up to dry eyes. Relieve the discomfort by using artificial tear drops or gels and remember to blink!
7. Palming
Sit straight at your workstation and rub your palms against each other till you feel them warm. The warmth of your palms helps soothe and relax tired eyes. Then, lightly cup your eyes with your palms and relax for 60 seconds. Count the seconds in your mind. Repeat this exercise two to three times whenever your eyes feel tired, or as often as you want. While palming, you can either rest your elbows on your desk or keep away from the desk and cup your eyes. Both ways are fine.
8. Splash water on your face
During breaks, splash water on your face while closing your eyes. This has an overall relaxing effect and helps you feel refreshed..
9. Use tea bags
Keep two used tea bags in the refrigerator before you leave for work. Once you are home, place the tea bags on your eyes for a few minutes as you relax. This not only soothes tired eyes, but also reduces puffiness.
10. Eat healthy
Incorporate Vitamins A, C, and E on a daily basis; eat citrus fruits, green leafy veggies, tomatoes, spinach, poultry and dairy products. Pack a box of chopped carrots, cucumber and fresh fruits and munch in-between meals at the office.
