, once founded a set of natural therapies to “exercise the eyes and improve vision”. However, his theory contradicts modern ophthalmology and optometry, and its effect is not supported by any scientific evidence. The American Academy of Ophthalmology points out that these “treatments” have no scientific evidence, and what they play is only a placebo effect.
so, where is Bates’ theory unscientific? Why can’t eye exercises really help people improve their eyesight?
is the opposite of “extraocular muscle relaxation”
Bates believes that the eyeball focuses by changing the shape, and the tension of extraocular muscle is the cause of ametropia, so relaxing extraocular muscle can improve vision. Therefore, he created a series of eye training methods, including covering his eyes, closing his eyes to shine on the sun or light, rotating his eyes, swinging, watching a variety of colors and so on.
however, his myopia theory is not consistent with the operating mechanism of human eyes. In fact, the function of human extraocular muscles is only to change the direction of the eye. It is another muscle responsible for eye focus – the ciliary muscle in the eye. The contraction and relaxation of ciliary muscle can change the properties of lens. Ciliary muscle is the muscle that really controls eye focusing.
then, what changes have taken place in the eyeball of myopia? The increased thickness of ciliary muscle, the posterior position of ciliary process and the thinning of scleral fibers can not be reversed by natural therapy. In addition to myopia, astigmatism cannot be reduced by exercising eye movement.
will wearing glasses damage your eyesight?
in addition to the theory of relaxing the extraocular muscles, Bates also stubbornly believes that wearing glasses for a long time will reduce vision. For this reason, he even often smashes patients’ glasses in the consulting room. Today, many people still think that wearing glasses will aggravate myopia. In fact, there is no evidence to support this claim. On the contrary, improper correction will accelerate the progress of myopia. For children, refractive correction is optimal or even mandatory.
and
need to be vigilant that the saying that “wearing glasses damages vision” may also bring more harm. If myopic people insist on not wearing glasses, they will put themselves and pedestrians at risk when driving. For children, uncorrected myopia can also lead to amblyopia.
“effective” illusion
although the theory is untenable and the actual effect is lack of evidence support, many patients still feel a temporary “vision improvement” after experiencing myopia therapy. This situation is actually an illusion brought by tear film.
there are very thin tears on the corneal surface, about 6-10 microns, called tear film. Every blink is the process of applying tear film. In addition to keeping the cornea and conjunctiva moist, tear film also has a very important function – to improve the refractive power of the cornea. The corneal surface is not smooth, and the tear film can help fill these irregularities and make the cornea smooth. When you stare at the computer for a long time and blink less, the tear film evaporates and the vision will be blurred. At this time, blink a few more times and the field of vision will become clearer. In
and
myopia therapy, covering the eyes with the palm is actually a dry hot compress, which can make the oil in the meibomian gland tube soft and easy to discharge, supplement the oil layer in the tear film and reduce the volatilization of tears. And another kind of “therapy” of closing eyes and rotating eyes is actually helping to smear tears evenly.
however, supplementary tear film has no real substantive effect on the treatment of myopia. If you need to moisturize your eyes, a drop of artificial tear will be faster and more effective than this method.
up to now, old Mr. Bates has died for more than 80 years. His pioneering work of using adrenaline to stop bleeding in ophthalmic surgery has made great contributions to the ophthalmology community. However, his theory and therapy have no scientific basis in the treatment of myopia. Now, let’s let the Bates therapists
