exercise for the eyes

Dear All,
During a recent visit to an optician, he told of an exercise for the eyes. It is must for all of us, who spend long hours at our desks, looking at the computer screen.
I Thought I'd share it with you.
Step I:-After every 26 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 23 times in succession, to moisten them. Step III: - Time permitting of course, one should walk 36 paces after every 36 minutes of sitting in one particular posture. Helps blood circulation for the entire body. Circulate among your friends if you care for them and their eyes. They say that your eyes r mirror of your soul, so do take care of them, they are priceless......
