• • • The Bates method is an aimed at improving. Eye-care physician, M.D. (1860–1931) attributed nearly all sight problems to strain of the eyes, and felt that were harmful and never necessary. Bates self-published a book,, as well as a magazine,, (and earlier collaborated with on a correspondence course) detailing his approach to helping people relax such 'strain', and thus, he claimed, improve their sight. His techniques centered on visualization and movement.

He placed particular emphasis on imagining letters and marks, and the movement of such. He also felt that exposing the eyes to sunlight would help alleviate the 'strain'. Despite continued reports of successful results, including well-publicised support by, Bates' techniques have not been shown to improve eyesight. His main proposition—that the eyeball changes shape to maintain —has consistently been contradicted by observation. In 1952, optometry professor wrote of Bates, 'Most of his claims and almost all of his theories have been considered false by practically all visual scientists.' Now tv keygen generator torrent.

Such occurrences have since been explained as a -like effect of moisture on the eye, or a flattening of the lens by the ciliary muscles. The Bates method has been criticized not only because there is no good evidence it works, but also because it can have negative consequences for those who attempt to follow it: they might damage their eyes through overexposure of their eyes to sunlight, put themselves and others at risk by not wearing their corrective lenses while driving, or neglect conventional eye care, possibly allowing serious conditions to develop.

The long-standing medical consensus is that this is accomplished by action of the, a muscle within the eye, which adjusts the curvature of the eye's. This explanation is based in the observed effect of temporarily preventing accommodation when applied to the ciliary muscle, as well as images reflected on the crystalline lens becoming smaller as the eye shifts focus to a closer point, indicating a change in the lens' shape.
