FOR YOUR EYES ONLY... Important Knowledge for regular PC Users!!!!!!!

During a recent visit to an optician, one of my friends was told of an exercise for the eyes by a specialist doctor that he termed as 20-20-20 .' It is apt for all of us, who spend long hours at our desks, looking at the computer screen. I Thought I'd share it with you. 20-20-20

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.
