The Bates method of natural vision improvement is a program created by ophthalmologist William Horatio Bates, M.D., which aims to correct what Bates, and teachers of the Bates method, see as faulty vision habits through relaxation techniques, exercises and optional activities and games.^[1] Bates claimed that his program improves sight and reverses ocular disorders to normal. It is argued by proponents that it works by eliminating "mental strain" of any kind and by restoring the "natural habits" of seeing. The Bates Method is the backbone of the natural vision improvement movement . The Bates method was first described in 1920 in a book entitled Perfect Sight Without Glasses, and then subsequently in his monthly magazine entitled Better Eyesight (1919-1930). This article is about the branch of medicine. ... William Horatio Bates (December 23, 1860 - July 10, 1931) was an American physician and ophthalmologist who developed what is now known as the Bates Method of natural vision improvement [1], a collection of techniques and exercises intended to improve vision. ...

Although many people claim to have been helped by the method, the efficacy of the Bates method is controversial.^[2] His theory that the eye does not focus by changing the power of the lens, but rather by elongating the eyeball, through use of the extraocular oblique muscles, was contradicted by mainstream ophthalmology and optometry of his day and is still today.^[3][4] Anecdotal evidence is an informal account of evidence in the form of an anecdote, or hearsay. ...

Bates' theories

Bates theorized that various types of "mental strain" were responsible not only for refractive errors (such as myopia, hyperopia, astigmatism, and presbyopia), but also for other abnormal eye conditions including strabismus, cataracts, glaucoma, amblyopia, conjunctivitis, blepharitis, and diseases of the optic nerve and retina.^[5] According to Bates, relaxation was the only cure for each type of strain.^[5] Refraction error, also known as refractive error, is an error in the focusing of light by the eye and a frequent reason for reduced visual acuity. ... Normal vision. ... Hyperopia, also known as hypermetropia or colloquially as farsightedness or longsightedness, is a defect of vision caused by an imperfection in the eye (often when the eyeball is too short or when the lens cannot become round enough), causing inability to focus on near objects, and in extreme cases causing...

Accommodation by extraocular muscle squeezing

Accommodation is the process by which the eye increases optical power to maintain focus on the retina. So when the eyes change from viewing a distant object to a near object accommodation is taking place. Light from a single point of a distant object and light from a single point of a near object being brought to a focus by changing the curvature of the lens. ... Optical power or dioptric power or refractive power is the degree to which a lens or mirror converges or diverges light. ... An image that is partially in focus, but mostly out of focus in varying degrees. ... Human eye cross-sectional view. ...

Bates rejected the orthodox view that accommodation was brought about by the action of the ciliary muscle on the eye's crystalline lens^[6], and claimed that focus was maintained by varying elongation of the eyeball caused by the extraocular muscles. Bates claimed that the lens played no part in accommodation and reported that the extraocular muscles, and in particular the oblique muscles, squeeze the eyeball to obtain focus by elongation. Excessive tension of the recti muscles may also make, according to Bates, the eyeball too short (leading to hyperopia, and excessive tension of the oblique and recti muscles makes the eye astigmatic). The ciliary muscle is a smooth muscle that affects zonular fibers in the eye (fibers that suspend the lens in position during accommodation), enabling changes in lens shape for light focusing. ... Light from a single point of a distant object and light from a single point of a near object being brought to a focus by changing the curvature of the lens. ... The extraocular muscles are the six muscles that control the movements of the eye. ... Hyperopia, also known as hypermetropia or colloquially as farsightedness or longsightedness, is a defect of vision caused by an imperfection in the eye (often when the eyeball is too short or when the lens cannot become round enough), causing inability to focus on near objects, and in extreme cases causing... Astigmatism is an affliction of the eye, where vision is blurred by an irregularly shaped cornea. ...

Bates regarded the superior and inferior oblique muscles as "the muscles of accommodation".^[7]

Refractive errors due to extraocular muscle squeezing

Bates regarded the refractive state of the eye as variable and disregarded the notion that permanent changes in the shape of the eyeball caused refractive errors. Instead, he stated that the shape of the eyeball responded instantly to the action of the extraocular muscles upon it.^[8] Refraction error, also known as refractive error, is an error in the focusing of light by the eye and a frequent reason for reduced visual acuity. ...

Bates claimed that straining to see at the near-point led to shortening of the eyeball resulting in hypermetropia (farsightedness), and that straining to see at the far-point led to lengthening of the eyeball leading to myopia (nearsightedness). At first this seems back-to-front, but by straining to see at the near-point Bates did not mean habitual close-work, or even tensing of the muscles, he meant 'straining' in a mental sense.^{[citation needed]} He makes this clear in his chapter entitled 'strain' where he says, "if the muscles respond to the minds desire, they do so without strain". Some have assumed that Bates saw prolonged tension in the extraocular muscles as directly causing eyeball deformation ^[9]. His 'mental strain' is quite unconnected with muscle tension, and he sees the maladjustment as being in the brain, not the eye^{[citation needed]}. Hyperopia (or more rarely, hypermetropia), also known as farsightedness or longsightedness, is a defect of vision caused by an imperfection in the eye (often when the eyeball is too short), causing inability to focus on near objects, and in extreme cases causing a sufferer to be unable to focus on... Normal vision. ...

Bates concluded that myopia was related to apprehension, or what some may call "anxiety". He reportedly felt that good vision was nature's way, and that any other way was a strained way of seeing. Bates believed that it was impossible to consciously relieve the eyes of this tensing, and instead developed his method as a means of effecting subconscious relaxation.

The concept that relaxing the extraocular muscles can reliably or predictably reduce refractive error has not been substantiated by patients whose muscles are loosened during strabismus surgery. Although small refractive changes may occur following this type of muscle loosening surgery (recession), these alterations are generally small, clinically insignificant, transient, and occur in both directions (stronger and weaker). ^[10] Isolating the inferior rectus muscle Disinserting the medial rectus muscle Strabismus surgery is surgery on the extraocular muscles to correct the misalignment of the eyes. ... In macroeconomics, the definition of recession is a decline in any countrys Gross Domestic Product (GDP), or negative real economic growth, for two or more successive quarters of a year. ...

Close work

Bates Method advocates believe that viewing books, computer monitors, and other near-vision activities are harmless, in fact a good exercise, as long as a person maintains correct vision habits. They also believe that eyeglasses are at best a crutch and at worst actually make vision with the naked eye worse.

Eyeglasses

Bates wrote: "At their best it cannot be maintained that glasses are anything more than a very unsatisfactory substitute for normal vision."^[11] He claimed that eyeglasses injured the eyes and did not restore normal vision.^[11] The refractive condition of the eye, he maintained, is constantly changing, from day to day and from hour to hour, and so the prescribing of corrective lenses can only ever be right at the time they are fitted, after which they force the eye to adjust to them.

Bates cited many disadvantages to eyeglasses, maintaining that they adversely affected color perception, contracted the field of vision, and caused dizziness and headaches when the wearer viewed objects off-axis.^[11] `

Bates' techniques

Bates claimed to have discovered that people with abnormal vision use their eyes differently than people with normal vision, and then created a system designed to help people to relearn the right vision habits. Advocates of the Bates Method claim that these vision habits are inseparably connected to normal vision. They assert that the Bates Method is a natural method that improves movement, relaxation, and circulation of the whole visual system. Bates' "exercises" are not aimed at muscle strengthening, but, like many yoga practices, are aimed at procuring a state of relaxation. Bates indicated that for his techniques to be effective eyeglasses must be discarded entirely, not simply worn less frequently or in a lower prescription.^[12]

Relaxation is at the core of the Bates Method, involving a set of practices which Bates advocates term "exercises in relaxation" and "movement exercises" ^[13]. They emphasize that the term "exercise" is used in the same sense as "memory exercise" and does not imply muscle strengthening.

Swinging involves deliberate movements of the body with relaxed awareness of vision.

Palming or cupping is one technique that advocates claim achieves relaxation of the mind and the eyes. Palming requires a person to gently cup the palms of the hands over the closed eyelids, and attempt to see "perfect black" in order to give the mind and the visual system as much rest as possible. Then the person sits for five to fifteen minutes (or as long he or she wants) breathing deeply and easily with good posture.

Sunlight exposure involves looking at the sun through closed eyelids. Bates considered light to be the "lifeblood" of healthy eyes. See the discussion on safety below regarding this controversial aspect of his program. The Bates method is a program created by ophthalmologist William Horatio Bates, M.D., which aims to correct vision habits with relaxation techniques, exercises and optional activities and games. ...

Central fixation was considered very important by Bates. Recognizing that only a very small part of the retina is capable of the highest resolution, he claimed that many people, when reading, allow the central fixation needed to maintain a sharp image to wander, so that they are attempting to focus using a low resolution part of the retina. He emphasized that good fixation is about relaxing and allowing the eyes to change gaze rapidly and naturally, rather than straining to fixate, which results in staring. Staring is the result of tension, according to Bates, and very bad.

Aldous Huxley and Margaret Corbett

The British writer Aldous Huxley (author of Brave New World) was a famous advocate of the Bates method. Huxley claimed to have achieved successful results in his book entitled The Art of Seeing. Huxley was among the students of Margaret Corbett, A "Bates Practitioner", who trained with Dr. Bates in 1930 and later authored Help Yourself to Better Sight. Aldous Leonard Huxley (July 26, 1894 – November 22, 1963) was an English writer and one of the most prominent members of the famous Huxley family. ... For other uses, see Brave New World (disambiguation). ... The Art of Seeing is a 1942 book by Aldous Huxley, which contains an explanation of the controversial Bates Method of visual re-education and an account of how the author applied its principles to improve his own poor eyesight. ... Year 1930 (MCMXXX) was a common year starting on Wednesday (link will display 1930 calendar) of the Gregorian calendar. ...

However, while Huxley undoubtedly believed his vision had improved, Bennett Cerf thought otherwise. In 1952 Cerf was present when Huxley spoke at a Hollywood banquet, wearing no glasses and apparently reading his paper from the lectern without difficulty: Bennett Cerf on Whats My Line?, 1962 Bennett Alfred Cerf (May 25, 1898 - August 27, 1971) was a publisher and co-founder of Random House, also known for his own compilations of jokes and puns, for regular personal appearances lecturing across the United States, and for his television appearances...

"Then suddently he faltered—and the truth became obvious. He wasn't reading his address—he had learned it by heart. To refresh his memory he brought it closer and closer to his eyes. When it was only an inch away he still couldn't read it, and had to fish for a magnifying glass in his pocket to make the typing visible to him. It was an agonizing moment."^[14] (p. 241: quotes Bennett Cerf re Huxley's vision in 1952)

In 1941, Margaret Corbett was brought to trial in California on a charge of practicing medicine without a license, but was acquitted. Later, together with others, including Huxley, she successfully fought a State Bill which would have banned teaching methods of sight improvement and relaxation without a medical or ophthalmic license. ^[15] Official language(s) English Capital Sacramento Largest city Los Angeles Largest metro area Greater Los Angeles Area  Ranked 3rd  - Total 158,302 sq mi (410,000 km²)  - Width 250 miles (400 km)  - Length 770 miles (1,240 km)  - % water 4. ...

Criticisms of the Bates Method

Theories of accommodation/focusing and refractive errors

Critics of the Bates Method reject the theory that human eyes accommodate, or focus, due to elongation of the eyeball caused by “squeezing” of the extraocular muscles, as has been claimed to happen in some animals. Critics of the Bates Method instead support the mainstream theory set forth by Hermann von Helmholtz that human eyes accommodate, or focus, due to the actions of the ciliary muscle (an intraocular muscle) and zonules changing the shape of the crystalline lens. To support this theory, critics of the Bates Method point to the action of various cycloplegic agents which temporarily paralyze accommodation by relaxing the ciliary muscle but leave the extraocular muscles, which control eye movements, unaffected. Modern equipment, not available to Bates, has made possible the observation of the eye in great detail. Modern observations have shown the lens changing shape when the eye accommodates. ^[16] Elwin Marg, writing in 1952 points out that "it would take about one millimeter change in axial length of the eyeball for each 3 diopters change of refractive power. Hence, a youth accommodating 15 D would shorted his globe by five millimeters." He continues: "to the writer's knowledge, no corresponding anterior-posterior corneal movement has ever been reported." ^[4] Another problem with this theory is that if it was true, intraocular lenses couldn't be used to cure presbyopia. ^{[citation needed]} Hermann Ludwig Ferdinand von Helmholtz (August 31, 1821 – September 8, 1894) was a German physician and physicist. ... Year 1952 (MCMLII) was a leap year starting on Tuesday (link will display full calendar) of the Gregorian calendar. ... An intraocular lens (IOL) is an implanted lens in the eye, usually replacing the existing crystalline lens because it has been clouded over by a cataract, or as a form of refractive surgery to change the eyes optical power. ... Presbyopia (Greek word presbyteros (πρεσβύτερος), meaning elder) is the eyes diminished ability to focus that occurs with aging. ...

Bates' other source of evidence was the ability of some aphakics to accommodate. Firstly, these cases are exceptionally rare and therefore should be considered exceptions to the rule rather than the rule ^[4] and, secondly, evidence has been presented that there is no change in the refractive power of the eye in these cases. ^[17][18] Aphakia is the absence of the lens of the eye, due to surgical removal, perforating wound or ulcer, or congenital anomaly; causes a loss of accommodation, hyperopia, and a deep anterior chamber. ...

Critics of the Bates Method contend that if the cause of myopia is continuous tensing of the muscles, either ciliary or extraocular, the Bates Method theory is that it should be possible to cure (or noticeably improve) it by causing intentional relaxation of the muscles; a process most commonly done using injections or topical administration of atropine. The mainstream consensus on this, however, is that no significant improvement of the vision is obtained when muscles are relaxed in this manner. Although Bates claimed that the evidence against the orthodox theory of accommodation was "overwhelming", he acknowledged that the effect of atropine supported the orthodox theory in "about nine cases out of ten".^[6][16] Atropine is a tropane alkaloid extracted from the deadly nightshade (Atropa belladonna) and other plants of the family Solanaceae. ...

Efficacy

Some behavioral vision therapists continue to practice the Bates method despite research demonstrating lack of efficacy.

Optometrists and ophthalmologists that are aware of his work remain skeptical. Skeptic Martin Gardner characterizes Bates's book in Fads and Fallacies in the Name of Science, as "a fantastic compendium of wildly exaggerated case records, unwarranted inferences and anatomical ignorance." Bates theory of accommodation suggested the contraction of the ocular muscles resulted in changes in focusing power rather than changes in the lens and contraction of the lens zonules. Gardner argues that current high-resolution dynamic ultrasonic biomicroscopy has shown Bates' theory of accommodation (by elongation of the eyeball) to be false. Gardner suggested that the Bates method may however work, to a limited degree, by increasing the trainee's ability to interpret and extract information from blurred images.^[14] Martin Gardner (b. ...

The purported benefits are generally anecdotal and medical research often shows no clinical benefit. The medical community is often critical of the Bates method and lack of evidence-based medical support.^{[16][19][20][21]} Anecdotal evidence is an informal account of evidence in the form of an anecdote, or hearsay. ...

In the eighties and nineties, interest in biofeedback in turn stimulated some research into the Bates method. It was found in one study that myopes could improve their visual acuity with biofeedback training, but that this improvement was "instrument-specific" and did not generalise to other measures or situations. ^[22] In another study an "improvement" in visual acuity was found but the authors concluded that this could be a result of subjects learning the task ^[23] Finally, in an evaluation of a training system designed to improve acuity, "no significant difference was found between the control and experimental subjects" ^[24] A 1997 review of this biofeedback research concluded that "controlled studies to validate such methods ... have been rare and contradictory." ^[25] Biofeedback mechanism. ... Normal vision. ... For the band, see 1997 (band). ...

A 2005 review of the literature on eye exercises concluded that: "Small controlled trials and a large number of cases support the (use of eye exercises in) treatment of convergence insufficiency. Less robust, but believable, evidence indicates visual training may be useful in developing fine stereoscopic skills and improving visual field remnants after brain damage."^[2] However, the report also concluded that "no clear scientific evidence" exists for the efficacy of eye exercises in the treatment of "vergence problems, ocular motility disorders, accommodative dysfunction, amblyopia, learning disabilities, dyslexia, asthenopia, myopia, motion sickness, sports performance, visual acuity, and general well-being." ^[2] Convergence insufficiency is a sensory and neuromuscular anomaly of the binocular vision system, characterized by an inability to converge the eyes or sustain convergence. ...

Safety

Avoidance of conventional treatment

Advocates believe the Bates Method to be safe. Critics concede that most of the Bates techniques are harmless, apart from the possibility that faith in the Bates system could deter people with eye conditions requiring prompt care from seeking conventional treatment. Professional Bates Method teachers use a disclaimer, which must be signed by the student, that emphasizes that a Bates Method teacher is not an Ophthalmologist.^[26] Ophthalmology is the branch of medicine which deals with the diseases of the eye and their treatment. ...

In humans the eye and brain development continues until approximately 8-10 years of age. For proper development of the visual pathways in the brain it is essential that clear images fall on the retina. Therefore it is very important that any refractive error is fully corrected in childhood in order to prevent the development of amblyopia. Refraction error, also known as refractive error, is an error in the focusing of light by the eye and a frequent reason for reduced visual acuity. ... Amblyopia, or lazy eye, is a disorder of the eye. ...

Sunlight exposure

Bates gives several examples of patients' vision improving after having looked directly at the sun,^[27] which in some situations may be dangerous. Figures in Chapter 17 of Bates' 'Perfect Sight Without Glasses' show several individuals looking at the Sun "without discomfort" and figure 48 shows somebody "Focussing the Rays of the Sun Upon the Eye of a Patient by Means of a Burning Glass" implying that this is a safe thing to do.^[27] Regarding "sun-gazing" as beneficial he goes so far as to say that: "In some rare cases... complete cures have been effected by this means alone."^[27] Regarding looking directly at the sun, Bates also remarks that: Sol redirects here. ...

"In my experience such light has never been permanently injurious. Persons with normal sight have been able to look at the sun for an indefinite length of time, even an hour or longer, without any discomfort or loss of vision. Immediately afterward they were able to read the Snellen test card with improved vision, their sight having become better than what is ordinarily considered normal."^[27]

According to Thomas R. Quackenbush, Bates modified this suggestion after having written Perfect Sight Without Glasses by stating that the sun should only be allowed to shine on closed eyes.^[28]

Other eye-exercise methods

In recent years, the growing interest in alternative medicine has led to an increase in the popularity of the Bates Method and other methods claiming success via visual training through eye exercises. One particularly controversial area is the efficacy of eye exercises in the treatment of myopia (near-sightedness) and whether the use of eyeglasses makes myopia progressively worse. Alternative medicine is defined as any of various systems of healing or treating disease (as chiropractic, homeopathy, or faith healing) not included in the traditional medical curricula taught in the United States and Britain.[1] Complementary medicine is defined as any of the practices (as acupuncture) of alternative medicine accepted... Normal vision. ...

Several points of view exist about the use of eye exercises to treat vision problems:

• Traditional mainstream ophthalmologists and optometrists use eye exercises to treat a limited range of problems, particularly problems involving muscular imbalances and problems with coordination of eye movement between the two eyes. (See orthoptics.)
• Functional optometrists and optometric vision therapists are licensed, credentialed doctors of optometry, who specialize in treatment that involves eye exercises. They hold that such exercises are useful in improving a wide range of visual conditions, including focusing problems. The methods used are said to be backed by clinical studies and publications in peer-reviewed journals. (See vision therapy.)
• The Bates method differs from other health systems that use eye exercises in a way that can be categorized as alternative medicine. Like homeopathic medicine, the treatments used and the explanations of how they are said to work are rejected by mainstream medicine^[14], despite personal testimony^[29] by people who claim to have been helped by such methods.

It is an eye-based exercise program marketed as an alternative to the use of glasses, contact lenses, and eye surgery to improve vision. It combines elements of the Bates method, but Bates practitioners are keen to distance themselves from it.^[29] The effectiveness of the See Clearly Method is disputed by scientists and mainstream eye care practitioners.

Pathogenesis and control of myopia: the modern debate

Main article: Myopia

Although not alone in his endeavors, Bates is commonly recognized as one of the first in the modern era to attempt to prevent, arrest, or reverse myopia and other refractive errors. His techniques (designed to eliminate "mental strain") have been largely rejected by mainstream ophthalmology as ineffective^[3], but certain pharmaceuticals, contact lenses, and surgeries have achieved varying degrees of success (at least on a temporary basis), as have vision therapy and plus lenses in the treatment of pseudomyopia.^{[citation needed]} Normal vision. ...

In direct contrast to research over the past ten to twenty years which has implicated heavy amounts of near-work as a contributing factor to the development of myopia^[33][34], Bates emphasized that that near-work and "overuse of the eyes" were not necessary to cause myopia, and claimed that he "made many dogs myopic by inducing them to strain to see a distance object". To Bates, refractive errors were due to a "loss of mental control" brought about by "strain", specifically "strain of the mind". He wrote: "The remedy is not to avoid either near work or distant vision, but to get rid of the mental strain which underlies the imperfect functioning of the eye at both points."

Despite considerable evidence that blurred images appear to trigger changes in the axial length of the eyeball through a complex feedback mechanism,^{[citation needed]} some Bates advocates hold the original hypothesis that "mental strain" is ultimately responsible for the development of refractive error through extraocular muscle squeezing of the globe. They contend that various eye exercises could affect a person's refractive error by altering the structure of the eyeball; however, there is no modern research that directly supports these claims.

Natural vision improvement

Bates is credited for being the founder of the Natural vision improvement.^[1] Various self-help books and programs exist claiming to improve vision "naturally" by various means.^[35][36]

Steven M. Beresford agrees with Bates regarding the possibility of improving eyesight naturally, saying in his book : "Pretending that the traditional use of 'corrective' lenses is safe and effective is no longer acceptable. The public must be told the truth and given accurate information about the alternative methods of treatment now available." In the book, Beresford et al assert that corrective lenses are neither safe or effective and that vision can be improved without the use of glasses or contact lenses.^[37] A corrective lens is a prosthetic lens worn on or before the eye, used to treat myopia, hypermetropia, presbyopia and astigmatism. ...

Natural Vision Improvement markets itself as a lifestyle method of improving eyesight by holistic means without the use of optical devices. It uses the Bates method "merged" with modern theories of brain function, character and responsibility for one’s self and state of being. ^[38]
