This utility model relates to a kind of myopia device.Relate to Patent classificating number A61 medical science or veterinary; Hygiology A61N electrotherapy; Magnetic therapy; Radiation is treated; Ultrasound wave is treated A61N1/00 electrotherapy; Its circuit A61N1/18 used applies electric current by contact electrode.

Background technology

Myopia (Myopia) refers to that eyes see nearby clear and see unclear a kind of pathological state at a distance.There is near-sighted people in the time seeing at a distance, be parallel to the parallel rays of the optical axis by the refraction of eye refraction system, converge in before retina, can not on retina, form imaging clearly, therefore cannot see clearly.Distant vision Ke Yi Tong Over concavees lens after myopia are corrected, and conventionally weigh ametropic degree with diopter, and 0 to-3.00D belongs to low myopia, and-3.00 to-6.00D belong to medium myopia, and higher than-6.00D is high myopia.The people of high myopic eye belongs to the high-risk group of some oculopathy, for example retina shedding because axis oculi is long.Myopia is all quite popular in the whole world.And Chinese near-sighted number has reached 1/3 of national population.

1. the ill cause of disease of myopia

Myopia has inherited genetic factors, but inherited genetic factors sometimes exaggerated, this is in recent decades just generally because of myopia, not so general myopia of ancients.Many people have myopia, but not myopia of its ancestors.Excessive learning burden, the use of various electronic products, additional bad use eye customs etc., are usually cause the long-time close eye of people and form near-sighted major reason.

It is generally acknowledged, excessive reading and other the closely movable excessive adjusting burden of bringing to eyes, be the main cause that myopia forms.Normal human eye is changing at a distance while seeing nearby from seeing, object in eye imaging will after move, thereby no longer drop on retina, the thing that people sees is fuzzy.Therefore, in order again to see object clearly, eyes need to be made adjusting, shrink ciliary muscle, allow crystalline lens become more protruding, thereby form stronger refraction, allow the picture of object come back on retina.But if long-term close eye, ciliary muscle, by spasm, temporarily loses the ability of loosening, thereby form pseudomyopia.If things continue this way, and the spasm of ciliary muscle also may stimulate the elongation (organic variation) of eyeball antero posterior axis, thereby form the true myopia that cannot reverse.

There is near-sighted people after wearing glasses for the myopia, can the in the situation that of eyes spasm, still see distant objects clearly.But, in the time seeing near thing, the burden of eyes will be larger, thereby also may form one and constantly deepen near-sighted vicious cycle: myopia causes wearing of glasses for the myopia, glasses for the myopia wear the larger burden of eyes while causing seeing nearby, larger cause the further intensification of myopia by eye burden, and then cause the wearing of glasses for the myopia of the higher number of degrees, so continuous number of degrees of deepening myopia and glasses, finally even cause more serious pathological change.This is also why myopia degree can not exclusively be corrected in some optician's shops in the time joining mirror to user, thereby allows the burden of eyes in the time seeing nearby be unlikely to too high.But this is also controversial.A research shows, the experimenter who not exclusively corrects myopia degree is faster than the speed of experimenter's myopia development of correcting the number of degrees completely on the contrary.But this research is also queried.

2. the main Related product of myopia and points for attention

2.1 glasses for the myopia.After myopia, eyes cannot be seen clearly at a distance, just can see clearly at a distance so need to wear glasses for the myopia.But, use glasses for the myopia to see for a long time can to add again nearby and reuse eye and bear and deepen near-sighted.Therefore, should not use glasses for the myopia (the particularly higher glasses for the myopia of the number of degrees) to see for a long time nearby.

2.2 use reading mirror (spectacles for long sight).Contrary with glasses for the myopia, spectacles for long sight can alleviate the burden of seeing nearby, thus pre-myopia prevention.This pre-myopic-preventing method is called as nearly fogging method.

2.3 use atropine (atropine) collyrium.Atropine (or its similar medicine, as the m receptor such as pirenzepine and tropicamide antagonist) can paralysis cilia-like muscle, loosens its spasm, thus pre-myopia prevention.But this class medicine also has side effect, comprise temporarily cannot see clearly nearby, very responsive etc. to high light.Multinomial research shows, atropine collyrium is effective to slowing down near-sighted intensification.

2.4 laser surgerys (LASIK).Laser surgery is at present uniquely can reverse fast near-sighted method, and to part, adult is suitable for.But it can not make people recover normal person's vision conventionally, and its possible side effect is also significantly, comprises xerophthalmia, dazzles light, degradation under night vision, even may be after the several years vision degradation.The wound that laser surgery stays on cornea can really heal never, may be subject to wound and misplace.In fact, U.S. FDA is responsible for Morris Waxler recent findings by the predecessor of LASIK technical certification, and LASIK manufacturer and partner thereof (comprising ophthalmologists) are concealed and forged in a large number about the safety of LASIK and the data of effectiveness in the time of application FDA certification.Ophthalmologists thinks, utilizes the safety of operation of new technique higher, although the data of Waxler thinks that the side effect of new technique is same.Therefore, the long-term safety of laser surgery remains controversial.

2.5 acupuncture and moxibustion therapy operations.Through the clinical proof of decades, acupuncture, for near-sighted treatment, is to receive satisfied effect.Expert points out, acupuncture and moxibustion therapy myopia acupoint selection is mainly the acupuncture point of local, extremity and abdominal part near the eyes, by stimulating these acupuncture points, plays thin channels and activating collaterals, promoting flow of QI and blood, the effect of the cloudy blood of liver and kidney tonifying.In acupuncture, coordinate the massage of eye, improve ocular blood circulation, increase eye district's nutrition, thereby improve curative effect.Acupuncture and moxibustion therapy, has good curative effect for pseudomyopia, and myopia is from the beginning of generally curing.Treatment, general 10 days is a course for the treatment of, just can see obvious effect a course for the treatment of, consolidates and needs 2-3 the course for the treatment of.For true myopia, eye fatigue is alleviated in the acupuncture that also can make a try, and delays further myopia and further increases the weight of.
