Info:
In his writings, Bates discussed several techniques which he claimed
helped patients to improve their sight. "The ways in which people strain
to see are infinite, and the methods used to relieve the strain must be almost
equally varied". Bates emphasized that no single approach would work for
everyone. His techniques were all designed to help disassociate this
"strain" from seeing and thereby achieve "central
fixation", or seeing what is in the central point of vision without
staring. He asserted that "all errors of refraction and all functional
disturbances of the eye disappear when it sees by central fixation" and
that other conditions were often relieved as well.
Some techniques include:
-Palming (covering the closed
eyes with the palms of the hands, without putting pressure on the eyeballs to
help bring about relaxation)
-Visualization (the metal imaging of the color black; that the darker
it appeared in the mind, and the smaller the area of black which could be
imagined, the more relaxed one was at the moment)
-Movement (moving the eyes back and forth to get an illusion of objects
"swinging" in the opposite direction. He believed that the smaller
the area over which the "swing" was experienced, the greater was the
benefit to sight)
-Sunning (exposing only the white part of the eyeball to direct
sunlight, and only for seconds at a time, after allowing the sun to shine on
closed eyelids for a longer period)
Results:
The purported benefits of Bates' techniques are generally
anecdotal, and their supposed effectiveness in improving eyesight has not been
substantiated by medical research. Several of Bates' techniques, including
"sunning", "swinging", and "palming", were
combined with healthy changes to diet and exercise in a 1983 randomized
controlled trial of myopic children in India. After 6 months, the experimental
groups "did not show any statistically significant difference in
refractive status", but the children in the treatment group
"subjectively ... felt relieved of eye strain and other symptoms." In conclusion these methods have been falsified and one should not attempt to use these methods as an alternative means of improving eyesight, especially sunning.
