With so 
many of us spending lots of time in front of the computer every day it 
comes to no surprise that research is showing a rise in visual problems.
 What can one do? First, it's important to find out how you can protect 
your eyes through eye health exams and by making a few minor changes in 
your computer viewing habits. 
    
Here are some helpful Eye Care Tips -
 
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.
     
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 colour, contrast and brightness levels to suit you.
     
 
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.
 
 
It's 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!
     
 
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.
     
 
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.
     
 
 
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.
     
 
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. 
    Have a nice day!!!!
