He asserted that the relaxation could be deepened in most cases by "palming", or covering the closed eyes with the palms of the hands, without putting pressure on the eyeballs. If the covered eyes did not strain, he said, they would see "a field so black that it is impossible to remember, imagine, or see anything blacker", since light was excluded by the palms. However, he reported that some of his patients experienced "illusions of lights and colors" sometimes amounting to "kaleidoscopic appearances" as they "palmed", occurrences he attributed to his ubiquitous "strain" and that he claimed disappeared when one truly relaxed. This phenomenon, however, was almost certainly caused by Eigengrau or "dark light". In fact, even in conditions of perfect darkness, as inside a cave, neurons at every level of the visual system produce random background activity that is interpreted by the brain as patterns of light and color. If while palming one ends up applying pressure to the eyes, this may increase the risk of glaucoma. === Visualization === Bates placed importance on mental images, as he felt relaxation was the key to clarity of imagination as well as of actual sight. He claimed that one's poise could be gauged by the visual memory of black; that the darker it appeared in the mind, and the smaller the area of black that could be imagined, the more relaxed one was at the moment. He recommended that patients think of the top letter from an eye chart and then visualize progressively smaller black letters, and eventually a period or comma. He cautioned against "concentrating" on such images, as he regarded an attempt to "think of one thing only" as a strain. While Bates preferred to have patients imagine something black, he also reported that some found objects of other colors easiest to visualize, thus were benefited most by remembering those, because, he asserted, "the memory can never be perfect unless it is easy." Skeptics reason that the only benefit to eyesight gained from such techniques is itself imagined, and point out that familiar objects, including letters on an eye chart, can be recognized even when they appear less than clear. === Movement === Bates thought that the manner of eye movement affected the sight. He suggested "shifting", or 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. He combined this with visualization, advocating that patients close their eyes and imagine movement of objects. By alternating actual and mental shifting over an image, Bates wrote, many patients were quickly able to shorten the "shift" to a point where they could "conceive and swing a letter the size of a period in a newspaper". Perhaps finding Bates' concepts of "shifting" and "swinging" too complicated, Bernarr Macfadden suggested simply moving the eyes up and down, from side to side, and shifting one's gaze between a near-point and a far-point. === Sunning === Bates advocated sungazing, characterizing ill effects as "always temporary". This is at odds with the well-known risk of eye damage that can result from direct sunlight observation. In his magazine, Bates later suggested 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. Posthumous publications of Bates' book omitted mention of the supposed benefits from direct sunlight shining on open eyes. Even on closed eyes, direct sunlight exposure poses a risk of damage to the eyelids, including skin cancer. == After Bates == After Bates died in 1931, his methods of treatment were continued by his widow Emily and other associates. In 1932, Gayelord Hauser published a book endorsing the Bates method but also adding new exercises and recommendations for his own dietary products. Most subsequent proponents did not stand by Bates' explanation of how the eye focused mechanically, but nonetheless maintained that relieving habitual "strain" was the key to improving sight. === Margaret Darst Corbett === Margaret Darst Corbett first met Bates when she consulted him about her husband's eyesight. She became his pupil, and eventually taught his method at her School of Eye Education in Los Angeles. She was of the stated belief that "the optic nerve is really part of the brain, and vision is nine-tenths mental and one-tenth only physical." In late 1940, Corbett and her assistant were charged with violations of the Medical Practice Act of California for treating eyes without a license. At the trial, many of her students testified on her behalf, describing in detail how she had enabled them to discard their glasses. One witness testified that he had been almost blind from cataracts, but that after working with Corbett, his vision had improved to such an extent that for the first time he could read for eight hours at a stretch without glasses. Corbett explained in court that she was practicing neither optometry nor ophthalmology and represented herself not as a doctor, but only as an "instructor of eye training". Describing her method, she said, "We turn vision on by teaching the eyes to shift. We want the sense of motion to relieve staring, to end the fixed look. We use light to relax the eyes and to accustom them to the sun." The trial attracted widespread interest, as did the "not guilty" verdict. The case spurred a bill in the Californian State Legislature that would have then made such vision "education" illegal without an optometric or medical license. After a lively campaign in the media, the bill was rejected. === Aldous Huxley ===
