Do you know that blinking and proper breathing helps to improve your eyesight?Try this exercise of Blinking and Breathing:

  1. First give 6 rapids and light blinks
  2. Shut your eye slowly for the gap of two whole breaths and repeat 4 times
  3.  You should not have more than a few seconds pass between one blink and the next. As a rough guide, between two and four blinks in each period of 10 seconds is right
  4. Do the eye staring and hold it for a while to make eyes immobile. Stop breathing during the process for about few seconds. Relax. Blink your eyes rapidly as you take two big breaths whenever you do the staring and breathing.

Practice the above rountine regularly, twice or more a day which will help to establish the correct tone in the muscle of the eyelids and develop better habitss of blinking.
