Abstract

The utility model relates to a short-eyesight corrector with multiple lenses. Two lenses can form a lens set, the lens which is nearer the eye is the concave lens, and the more near the eye, the better effect is obtained. The concave lens can correct the eyesight focus to make a user see objects far beyond clearly and is provided with the overcompensation to correct excessively. The lens far away from the eye forms the convex lens, the property of which opposites the nearer lens according to the overcompensation. When lens combination which is selected with appropriate diopter is used, the final image can generate at the front position of the central optic axis, and the virtual image of the object converted by the lens set is designed and controlled to be converted in the farther position to alter the previous operation habit of the eye. In another different space, by the natural operation of the entire vision physiological function and the balanced habit, the pseudomyopia can be equalized gradually, and the axial length of the eye can not be lengthened abnormally because of the habit to achieve the benefit of corrected eyesight.

Description

Many eyeglasses myoporthosis device

Technical field

The utility model relates to a kind of myopia correction device, particularly a kind of many eyeglasses myoporthosis device.

Background technology

Physiology running (Physiology of sight) principle by vision, a people's outer eye muscle may command eyeball makes the optical axis alignment object of sight line, and after visible light clashes into the reflection of this object, pass cornea (Cornea), aqueous humor (Aqueous humour) in anterior chamber (Anterior chamber) and the back room (Posterior chamber), crystalline lens (Lens), the vitreum (Vitreous body) of sclera (Sclera) institute dressing, go up the real image (real image) that produces handstand at nethike embrane (Retina), if the image that this moment, nethike embrane produced can not focus on (focus), then be positioned at intraciliary involuntary muscle (involuntary muscles) and accept the instruction of oculomotor nerve (Oculomotor nerve), meeting is moved and is changed lenticular shape, up to image focusing till clear, the signal of nethike embrane sensed image is delivered to brain via optic nerve (Optic nerves) again and translates and release (interpretation), makes more message and handles.

And the reason that near-sighted formation can't improve has a lot, wherein one be exactly a influence with eye custom, because unusual is accustomed to eye, intraciliary muscle is unidirectional constantly, single habitual the use, making itself and crystalline lens produce excessive one-way movement can't reply naturally, pseudo-myopia is control and sees near ciliary spasm or cramp, can't discharge the crystalline lens of excessive adjusting and cause, if continue its old habits and customs of accumulation, in the course of time, the axial length of eyeball also can undesiredly be elongated, particularly in eyeball and vision physiological stage of development, this problem is the most serious, and cause image at the nethike embrane difficulty focusing, and continue its old habits and customs of accumulation if ignore, worsening becomes high myopia, then may cause fearful pathology, as detached retina or the like.We have realized that at present, gently, it is not fearful that medium myopia does not see the problem of Chu, can see as long as correct defects of vision, but in, high myopia just begins and will bear fearful risk, yet Rome is not to cause in one day, canvass this understanding, can further recognize, the reason that causes myopia is to control and to improve, otherwise may cause terrible consequences, except pathology and other reason, unusual is noticeable reason of the utmost importance with the eye custom, what this habit had more can entail the next generation, makes that the next generation is easier a similar tendency.

Traditional near vision orthosis be at before focusing in nethike embrane, impose concavees lens and corrected and make its normal focusing, this provides the user to recover normal sight really and has looked the instrument of ability.But, but can't change user's custom and environment, so the user must continue his custom in the past with eye always, consequently Jin Shi people almost can keep near-sighted always, even the number of degrees constantly increase.The multi-focus lens of directly correcting defects of vision can slow down same custom, but can't thoroughly reverse inductive education be accustomed to, balanced old customs, in actual life, if be the people of myopia, few people understands nature becomes no near-sighted state gradually, the result of old customs that Here it is because traditional orthosis can't be forgone.Machine or method that many visual trainings are also arranged on the market, where the shoe pinches are that people's eyesight is the important tool of an acquired information, fuzzy problem has appearred in eyesight, can not light in order to train, but cause can't acquired information problem, only cause and can in limited and short time, train.Therefore, effect is limited, and making the mankind cause one of reason of high myopia is habit problem, is difficult to obtain thoroughly improving completely.

Summary of the invention

The purpose of this utility model provides a kind of user of confession and recovers normally to see to look many eyeglasses myoporthosis device of ability.

Above-mentioned purpose of the present utility model is to realize like this, a kind of many eyeglasses myoporthosis device, it is characterized in that: two lens combination at a distance of suitable distance in front and back are made into lens combination, and wherein the lens near eyes are concavees lens, and the lens far away apart from eyes are convex lens.

The utility model is elaborated with instantiation below in conjunction with accompanying drawing.

Description of reference numerals: 1 concavees lens; 2 convex lens; 3 virtual images; 4 eyes; 5 objects; 6 prisms.

Embodiment

As shown in the figure, the utility model mainly uses lens combination that two lens form as basic framework, near eyes be concavees lens 1, and far away be convex lens 2, both can install by same stand, also can be mounted combination respectively and keep one apart from formation; Wherein concavees lens 1 level off to zero good more more apart from eyes, it is preferable using contact lenses, and rectifiable user's eyesight and being focused on enables to know and sees distant objects, and the overcompensation of tool one overcorrection, apart from eyes convex lens 2 far away, then, become and nearer concavees lens 1 incompatible lens according to the overcompensation value of concavees lens 1.

The diopter of the long-range convex lens of the utility model 2 and near-end concavees lens 1 can be optionally collocation design mutually, the effect of near-end concavees lens 1 is that compensate for myopia person can see the ability than far object clearly in addition, otherwise, if there be not the auxiliary of near-end concavees lens 1, only use long-range convex lens 2, then not only user's eyesight can not obtain suitable rectification, sees between for the moment fuzzylyyer than far object on the contrary, and can have influence on user's study, work and lives.And the design of concavees lens 1 will make the normal naked diopter of looking not enough of its diopter overcompensation basically; change with the eye custom to induce; if there be not the auxiliary of overcompensation; the scope of a lot of distances can't be by suitable conversion; imperious eyelash flesh can't be stable far object is stablized relaxation exercise because of focusing; so that can't fully use; and; under the situation of normal acquired information; the user is easy to just can't persevere; overcompensation of the present utility model can also produce the effect of prompting; the user can feel painstaking because see near object; and can excite him to want to use convex lens 2 to solve the problem of seeing near object, more order about him and form a habit.

As shown in Figure 1, utilize combination of lenses of the present utility model, allowing last imaging (final image) can be created in sight line optical axis (central optic axis) locates than the front position, and the virtual image (virtual image) 3 of object 5 after the lens combination conversion, then be designed control transformation at a distance, so eyes 4 can obtain being different from naked object distance of looking and big or small sensation, ciliary body and crystalline lens move for adaptation, attempt adjusting diopter, though last imaging still can be on nethike embrane, retina resolution for fixing situation under, the change of object size visually, directly changed the identification of vision, and the utility model has also possessed the ability that produces the real image size on nethike embrane that can change in the vision distance of conversion object, directly controls identification, if identification is enough, then allow eyes not need the too close access message that gets final product, otherwise, if identification is not enough, then subjective, can want to allow eyes need the more close access message that just makes things convenient for.

The light that reflects from object, if do not pass through the processing of any device or system, the adjustment of ciliary body correspondence distance just equals actual range so, the utility model then can be under the situation that does not influence normal study, work and life, for the ciliary body that we were concerned about, provide corresponding comparatively sensitive sensation apart from conversion, make ciliary body with new custom, adjust muscular movement, and then improve stopping that eyesight makes and worsen.

After eyesight goes wrong, if without any the assistance of instrument, then because do not see Chu Dongxi, have uncertain sense psychologically, also do not allow a people to be in the state that a kind of information is broken off at any time in the actual life, therefore, after eyesight went wrong, common people still needed to correct.For the myope that causes because of custom, suppose the regular ground of our energy, books are zoomed into 10 times be placed on outside 10 meters, read for it, they are bound to can be when not needing painstakingly to change habits and customs, change them easily and observed the custom of object, so, the degree that just can alleviate their original pseudo-myopias because of different customs of a specified duration and of a specified duration is to the pseudo-myopia at initial stage, if method is correct, also can recover the normal naked ability of looking.

The orthosis of commonly using, relax muscular tone by directly alleviating the number of degrees, then influence user's study, work and life at once, even can control the state of muscle, also can't provide bigger amount of exercise to watch at a distance, particularly when the ametropic low number of degrees, because the number of degrees can't provide the space that down alleviates the number of degrees more very little again, pseudo-myopia for the initial stage, there is no too big effect, also do not promote the advantage of magnification, that is the advantage that the orthosis commonly used can not provide.In addition, use the utility model at any time,, just can obtain normal distance vision immediately as long as remove convex lens 2 if can't see clearly than far object the time.

The utility model utilizes long-range convex lens 2 and the many eyeglass combinations of near-end concavees lens 1 for basic device, as the instrument of vision correction and training.In case of necessity, the utility model can also impose the distance conversion that bifocal or zoom lens are strengthened closer object at any time, improvement is apart from conversion ratio, can also use and add convex lens, so that strengthen the training opposite with old customs at any time, long-range convex lens 2 are if use bifocal or multifocal lens, and can keep as far as possible is convex lens equally, and can keep the diopter scope of convex lens 2 not too big, therefore be difficult for causing user's moment maladjustment.Long-range in addition convex lens 2 do not limit with general eye glass frame and support, it is various soft, rigid contact lenses that near-end concavees lens 1 optionally also can not limit, also can be the lens of other extremely close eyeball, the mode of all right wear-type supports employed long-range convex lens 2 of the utility model and near-end concavees lens 1.

In addition, object is exaggerated and makes object identification visually improve, and observes the object details and more can not make the user want more to press close to object, produce on the nethike embrane picture object far away, be very beneficial for the remote focusing of eyeball.Therefore the utility model provides visual object magnification simultaneously, relatively helps training observation habit, makes the user because inducing of identification used the eye custom and change.

The characteristics of the utility model vision correction are to be improved as purpose, the motion of balanced eyeball involuntary muscle at the visual problems that causes myopia because of custom.Except correcting user's focusing, providing the user to recover normally to see the ability of looking is able to outside normal study, work and the instrument of living, just see clearly under the situation of the object that Chu needs, also consider to allow eye user's ciliary body and crystalline lens operate in the use interval opposite with original custom.Promptly,, become than the far vision distance by closely extending optionally with the object in the environment of myope not at specific object.

The utility model can stage by stage, gradually be strengthened the training opposite with old customs, and it is well-adjusted therefore more easily to reach the user.In addition long-range convex lens 2 and near-end concavees lens 1 can be optionally separately at a glance mutually collocation design that is to say to be respectively two that to get a desired effect optionally independent design becomes lens combination.Gather in order to improve spoke, i.e. the problem of two an eye line angles then can be in convex lens 2 front and back, as shown in Figure 2, install a prism 6, the mat refraction angle changes incident angle, form closely littler angle, promptly sight line does not need closely excessively inwardly concentrating, and it is comparatively natural that reality is closely changed.

And the utility model final objective is to pursue all lens are all removed, with the myopia correction is example, actual the utility model experiment achievement of using is to have reduced by 100 after 2 years to spend to 150 degree, for the false myopia at initial stage then at one month after three months, reduce by 25 and spend to 50 degree, causing is the method for a simple possible.

Press the utility model and remove the nonoperative mode that adopts, correct user's focusing, providing the user to recover normal the sight looks outside the instrument of ability, can also allow eye user's ciliary body and crystalline lens operate in the use interval opposite with old custom, with balanced old customs, finally reached all lens are all removed.
