Summary

William Horatio Bates Better Eyesight Magazine — September 1920

If one's memory and imagination are imperfect, they can be improved by consciously making them worse than they arc. Persons with imperfect sight never remember or imagine the letters on the test card as perfectly black and distinct, but to imagine them as grey and clouds is very difficult, or even impossible, and when a patient has done it, or tried to do it, he may become able to avoid the unconscious strain which has prevented him front forming mental pictures as black and distinct as the reality.
To make imperfect sight worse is always more difficult than to lower normal vision.

After I had learned to "palm," I learned to "swing.” The reason I strained my eyes so when looking at the card was that I stared at one place. So by imagining the letter was swinging like a pendulum, I moved my eyes instead of staring as I had done before. At first the swing was a long one, but after practicing for some weeks, I began getting it shorter until it was only half an inch on each side of the letter. The short swing was more difficult to do than the long one, but it helped more in the end.
