Bates Method Principles of Eyesight Improvement: Blinking

Because straining to see is what worsens vision, a lot of people with imperfect vision are able to, after a period of rest, see an object clearly for a fraction of a second.

If the eyes are closed before the habit of tension reaffirms itself, it is sometimes possible to achieve permanent relaxation very rapidly. This practice of “blinking” has been useful to many people who were incapable of improving their vision with other methods.

Rest the eyes for a few minutes by closing them or palming.  Then, look for a fraction of a second a letter of the eyechart, or a very small letter if you have problems with your near vision. Immediately close your
eyes and repeat.
