NEI(Natural Eyesight Improvement): What is the principle of Centralization?

Question

I am a Natural Eyesight Improvement Instructor. For those interested in learning about Natural Perfect Eyesight I am going to ask questions designed to lead people in Relearning how to See clearly and naturally. I will ask as many questions as people will participate in. I believe most of the information needed is available on the internet, but all the answers are in the book I have listed on my website. I will choose the most correct, thorough, and down to earth answers.

Answer 1

...are you talking about Bate's method? If that's the case, Bates asserted that "The eye with normal vision, therefore, sees one part of everything it looks at best, and everything else worse, in proportion as it is removed from the point of maximum vision; and it is an invariable symptom of all abnormal conditions of the eyes, both functional and organic, that this central fixation is lost."

thus, he characterized one "symptom of strain" as poor eyesight and claimed it could be relieved by "any method that relieves strain".

On a side note, His techniques have not been shown to objectively improve eyesight and his main physiological theory, that the extraocular oblique muscles adjust the shape of the eyeball to maintain its focus, was rejected by mainstream ophthalmology and optometry of his day, and is still rejected today.
