Description

Eye health-care instrument

This utility model is a kind of of health and fitness facilities, is to be fit to normal eye, myopia and the hypermetropia eye muscle that is used to exercise to strengthen a kind of optical instrument of eye regulating power.

Health and fitness facilities is of a great variety at present, but is primarily aimed at the muscular training of body trunk and extremity.And at eye muscle, especially the health and fitness facilities of ciliary muscle is rare.If ciliary muscle can not get exercise, or else note ocular hygiene, the long-term spasm of ciliary muscle, it is stiff to become, follow the string, compressing axis oculi elongated generation physiological myopia, i.e. pseudomyopia is if further develop, elongated axis oculi is fixed, and just becomes pathologic myopia, i.e. true myopia.The method of treatment myopia now is a lot, is divided into two classes substantially.One class is that methods such as eye dripping liquid medicine, medicine eyeshield are the medicine method of representative, some effect at that time, and drug effect was promptly got back to original vision in the past, and life-time service also has side effect.Another kind of is to be the acupuncture point method of representative with acupoint massage, acupuncture of a point, acupuncture point electric pulse therapy, owing to be not to directly act on ciliary muscle, effect is slower, and curative effect is not lasting, and the prerequisite of acupuncture point method is to aim at the acupuncture point, and the layman is difficult to grasp.Above therapy is that near-sighted mechanism is not understood to the main cause of myopia poor effect, and the axis oculi of pathologic myopia is elongated fixing, more than any therapy all powerless to it, can only wear suitable glasses, rather than treatment.If not treat, only carry out operation on cornea, but its risk and expense all are very big.Pseudomyopia is that physiological myopia is reversible, as long as can loosen ciliary muscle, axis oculi recovers normally naturally, so pathologic myopia can't be controlled, physiological myopia is not disease.If not to treat by disease, the one, DeGrain, curative effect is not lasting, and the 2nd, have side effect.Loosening ciliary muscle modal also is that the method that obtains ophthalmic industry approval is " fogging method ", promptly wear 200 degree presbyopic glasses and see thing more than half an hour, myopia is worn presbyopic glasses and is seen thing as in the mist, unintelligible, in order to see object clearly, ciliary muscle must extremely loosen, and the shortcoming of fogging method is must wear mirror more than half an hour at every turn, and the time is oversize.The up-to-date model YP-9 type vision care instrument of Shanghai institute of physiology of Chinese Academy of Sciences development, utilize optical principle, one group of sighting target is made back and forth movement clocklike on far and near distance, induce ciliary muscle to do to shrink, loosen and regulate exercise, strengthen its regulatory function, thereby remove ciliary spasm fast.Its weak point is that the exercise time is short, can not fully remove spasm, and overlong time then easily causes ciliary muscle fatigue.Consider the difference of human body, must keep certain exercise time, thereby behind the exercise, eyeball has the acid sense of rising, and to see thing far away or close order have a rest after, could survey the degree of vision raising.From removing the experience of finger spasm, contrast the method for above-mentioned releasing ciliary spasm, obviously find out the deficiency of said method.Long when writing the word time, finger possibility spasm if adopt medicine method principle, immerses finger in the liquid medicine of loose muscle, and time weak point dose is little, and effect is little, and the big time of dose is long, and finger is with function out of hand.If use the acupuncture point method, even find accurately at the acupuncture point, its recovery time is also not necessarily short recovery time than nature, and writes again, also may continue spasm.This more convictive proof, muscle spasm should with the treatment method, even and produce effect, also be instantaneous curative effect,, make it to be in relaxation state if by force the spasm finger is broken off with the fingers and thumb directly, inertia is in relaxation state just as fogging method makes ciliary muscle by force again, and its recovery time is longer.And ceaselessly loosen the contraction finger muscles, just as YP-9 vision care instrument principle, constantly finger is stretched in bending, can remove the finger spasm fast.But cycle-index very little, can not fully remove spasm, then easily causes muscle fatigue too much.The easier spasm of writing again.And best restoration methods is the contracted finger several times of loosing one's grip, make muscle fully remove spasm after, stretch finger again, muscle is fully loosened, can remove muscle spasm fast, can make loosening all muscles again.At the exercise of physiological myopia, then should adopt the principle of YP-9 type vision care instrument at the beginning, after spasm is removed, adopt the fogging method principle again, ciliary muscle is fully loosened.

The purpose of utility model provides a kind ofly can remove eyelash shape muscular spasm fast, can fully loosen ciliary muscle again, the Eye health-care instrument that makes ciliary muscle fully be exercised and loosen.

Utility model is achieved in that from eyepiece watches the sighting target that is back and forth driven along optical axis by driver.Obviously, also can reach effect same by the reciprocating motion of driver drives eyepiece.Thereby, just can induce ciliary muscle contraction to loosen as long as driver drives one of eyepiece and sighting target at least to move back and forth along optical axis.For the more effective ciliary muscle that loosens, when utility model had adopted time controller and localizer that the controlled and motion of time of sighting target relative motion is stopped, the position of sighting target and eyepiece was determined.Time controller can manually be controlled, and also can adopt intervalometer or cyclelog to control automatically.So that whole exercise in the cycle, has certain motion dwell time.Even can stop, moving, stop again, motion again ..., not to move always or stop always as long as guarantee the whole exercise time.Position when localizer control stops, the distance of sighting target and eyepiece was determined when the assurance motion stopped.For normal eye and physiological myopia or mixed myopia, sighting target is preferably in 2 diopter places behind the eyepiece, promptly is equivalent to wear 200 degree presbyopic glasses, and preferably is in 4 diopter places before eyepiece Jiao for hypermetropia or presbyopia, be distance of distinct vision place, so that its exercise is seen the ability of nearly thing.Time controller and localizer can be integral, and become the time location controller.

In order to be used for presbyopia, hypermetropia, near-sighted and normal eye exercise simultaneously, it is preceding defocused convertible that localizer is preferably made coking, and it is adjustable that at this moment eyepiece preferably makes diopter.

Sighting target can be in kind, also can be the eyepiece imaging.When being material object, can adopt fixed or removable picture, also can adopt luminous luminous point, light beam, preferably adopt game machine or small tv machine to make sighting target, to improve exercise interest.When sighting target itself is not luminous, can adopt modulation or non-modulation optical illumination; When sighting target itself is luminous, but the sighting target of modulated luminescence.When light modulated is thrown light on or be luminous,, also can exercise and shrink the muscle of pupil because light intensity changes.

Driver can adopt mechanical type, electromechanical or electronic type.When adopting electronic type, preferably driver, time controller and localizer are done on a circuit board, to make incorporate sighting target and driver control system.The time location controller also can adopt Single-chip Controlling, when adopting Single-chip Controlling, and the also modulated luminescence of may command sighting target or modulation illumination.

The axial movement of relative motion between sighting target and the eyepiece is preferably between 6 to 8 diopters.When both relative motioies, except the resolute that along the axially-movable of optical axis, can also have vertical axial to move, make when exercise, not only exercise is regulated the ciliary muscle of eye, and oculomotor other muscle of control of also can exercising also has certain exercise effect to stravismus.Motion frequency also can change in addition, and preferably frequency slows down gradually.

Utility model generally makes monocular, also can make biocular type if be used for eyes exercises.

Utility model is owing to adopt non-treatment means, and the method for the ciliary muscle of promptly exercising is removed the spasm of ciliary muscle, thereby effect is obvious, and is without any side effects.Compare with fogging method and YP-9 vision care instrument, have that to remove ciliary spasm fast, can fully loosen the advantage of ciliary muscle.Get the chief of above-mentioned two kinds of methods, keep away its shortage, being equivalent to gymnastics exercise back increases reorganization, makes it to become a complete exercise scheme.In addition because the resolute and the light modulated illumination of vertical optical axis axial-movement, the ciliary muscle of the control eye regulating power of not only can exercising, other eye muscle of can also exercising are arranged.Thereby not only can be used for myopia, can also be used for the exercise of hypermetropia, stravismus and normal eye.Can effectively exercise eye muscle, remove the eyestrain, strengthen the regulatory function of eye muscle.
