20-20-20 rule for good health.

During a recent visit to an Optician, one of my friend was told of an exercise for the eye by a specialist doctor in USA which he termed as "20-20-20". I found it apt for all of us, who spend long hours at our desks, looking at the computer screen. 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 eye,
a must-do for the tired eye.


Step II :


Try and blink your eyes for 20 times in succession, to moist it.


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.


Pls circulate among your family and friends  for their benefit.
