Abstract

The utility model relates to a pair of eyesight recovering glasses which provides a pair of glasses which has eyeglasses adopting optical wedge and can treat myopia and hyperopia through the different placing modes that the thick sides of the eyeglasses are arranged inwards or outwards. The utility model utilizes the refraction function of the optical wedge and the image combining function of both eyes to ensure that the eyes are in a far-looking state when seeing near objects and are in a near-looking state when looking far objects, therefore the utility model regulates ciliary muscles to generate integrated relaxing force or tensile force so as to change ametropia and recover the normal length of optic axes. The utility model can select moderate correction intensity through rotating the eyeglasses so as to prevent and treat true myopia, pseudomyopia and the hyperopia.

Description

Vision returns mirror

This utility model belongs to myopia, hyperopic treatment glasses.

Before this utility model was finished, generally the glasses of the treatment myopia of Cai Yonging had eyesight improving device, Micropole glasses, physical therapy glasses etc.Eyesight improving device (Chinese patent application numbers 90209005.4, January 1 1992 day for announcing) profile is similar to contact lens, because its principle is to massage eyeball by changing air pressure, belong to the external force effect, problem such as do not solve fundamentally that the crystalline lens diopter increases and axis oculi is long, not only treatment needs spended time, and the very fast eyestrain that is caused by the operation of various nearly eye of the massage curative effect of short-term offsets, so effect is unsatisfactory; Once the Micropole glasses that commanded a ready sale in the market in 1993 proposed in its operation instructions to make eyes be in resting state by the pinhole imaging system principle, thereby made ciliary muscle obtain to loosen.But in fact the regulating action of the set effect of eyes and ciliary muscle is extremely close, and pinhole imaging system does not reduce the set effect, so ciliary muscle is loosened, can not have an effect to the axis oculi that has increased, only when looking in the distance, play to increase and look effect.And can not drop on the focus by two aperture centers simultaneously because of two eye pupil holes when closely reading, easily cause in the optical fundus oblique.Also have the Micropole glasses visual field narrow and small, make the people be difficult to concentrate one's energy; Physical therapy glasses (China Patent No. 92219991.4, Granted publication CN2135789Y) adopt mist to look therapy and the pinhole imaging system principle combines, when the myope sees through the reading of presbyopic glasses sheet, force in the process of oneself seeing writing clearly looking effect owing to mist, force ciliary muscle to produce in the other direction and regulate, loosen effect, but that this loosens effect is fainter thereby play, more be difficult to form comprehensive relaxation force greater than this condition of tensile force, so treatment time is longer.For preventing and treating pseudomyopia certain curative effect is arranged, the true myopia elongated for axis oculi then has little effect, and its mist is looked effect and lens effect and made the people be difficult for energy equally to concentrate.

The purpose of this utility model is to provide a kind of above-mentioned shortcoming that overcomes, utilize the refraction action of wedge to impel eyes self to regulate and can the regulating and controlling amplitude, different modes of emplacements by eyeglass both can be treated myopia, can treat again hypermetropia, fast, the outstanding effect glasses of curative effect.

The purpose of this utility model is achieved in that eyeglass is plane wedge or curved surface wedge; The side that two eyeglasses are thick is all placed inwardly or all outwardly; The lens frame that eyeglass is housed is inserted mirror holder, and lens frame and mirror holder are provided with the adjusting detent mechanism for concerning movingly between lens frame and mirror holder.

Compared with the prior art, this utility model affords a wide field of vision, it is clear to look thing, can finish treatment in daily studying and living.And this vision recurrence mirror belongs to fundamentally to be proofreaied and correct, so treatment cycle is short, and good effect.When the mode of taking the thick side of wedge eyeglass to place inwardly, can treat true and false property myopia, when the mode of taking the thick side of wedge eyeglass to place, can treat hypermetropia outwardly.The utlity model has the scalable function, can guarantee moderate correction intensity.

Fig. 1 is the structural representation of plane wedge eyeglass;

Fig. 2 is the cross-sectional view of curved surface wedge eyeglass;

Fig. 3 is a structural representation of the present utility model, and 1 is mirror holder among the figure, and 2 is eyeglass, and 3 is lens frame, and 4 for regulating detent mechanism, and 5 is the scale indicatrix;

Fig. 4 be the A-A of Fig. 3 to cutaway view, 1 is mirror holder among the figure, 2 is eyeglass, 3 is lens frame, 4 for regulating detent mechanism.

Fig. 3, Fig. 4 have described a kind of embodiment of the present utility model.The outer surface of two lens frame (3) is marked with-5～+ 5 scale, has 10 grooves on its periphery.Eyeglass (2) adopts the plane wedge, and the angle of wedge of two eyeglasses is 8 degree, and aim at scale+5 and is fixed in the lens frame (3) at a thickest place, and then install to together on the mirror holder (1), and make it circumferentially freely to rotate and axial restraint.And in the blind hole in mirror holder (1) outside, be equipped with and form the spring of regulating detent mechanism (4) and bump pearl, indicate scale indicatrix (5) in the centre.When with the hands rotating two lens frame (3) simultaneously, make the scale indicatrix point to scale+5 successively by-5 o'clock, bump pearl and also be pressed in 10 grooves of two lens frame (3) to guarantee that two lens frame (3) keep relative stability on mirror holder (1) by spring successively.When scale be on the occasion of, promptly the side that eyeglass is thick is when symmetry is placed relatively inwardly, this utility model can be used for treatment myopia, will notice guaranteeing that scale indicatrix (5) points to the identical graduation on two lens frame (3) this moment.

Because the set effect of eyes conforms to the regulating action of ciliary muscle and coordinates, look object distance from nearer, medial rectus shrinks stronger, make two eyeballs inwardly change simultaneously so that two double images of being seen are merged, promptly see object at the moment clearly, at this moment set effect is just stronger, and ciliary muscle is also more nervous, thereby the crystalline lens diopter is increased.So long-time, just can form pseudomyopia.If continue so to go down again, the tensile force of ciliary muscle just can impel axis oculi elongated at leisure, thereby forms true myopia.

The patient who causes myopia for the operation of long-term nearly eye, when carrying out nearly eye operation owing to look the photopic vision scope that thing is positioned at the myope, so the time can wear this vision and return mirror, and make the thick side of eyeglass inwardly symmetry place.Under the situation that eyes are not regulated, because the refraction action of wedge, for left eye, be equivalent to wedge with the object segment distance that moved to left,, then be equivalent to wedge the object segment distance that moved to right for right eye, make the object that to see clearly originally on the retina of eyes, form double image at the moment, i.e. diplopia.But because the intensive picture function of closing of optic nerve, can be as much as possible by regulating ciliary muscle and lateral rectus, make the outer simultaneously commentaries on classics of double eyeball, the set effect reduces, ciliary muscles relax also produces comprehensive relaxation force, the also corresponding attenuation of crystalline lens, diopter reduces, and these a series of variations make eyes that double image is clearly integrated and are in the state of looking in the distance.When rotation lens frame (3) makes scale change by+1 to+5, be in the horizontal vertical plane of eyeglass during the ascending variation of angle, the tensile force that ciliary muscle produces will constantly reduce and comprehensive relaxation force will constantly increase, when this comprehensive relaxation force during greater than tensile force, for pseudomyopia, can remove the spasticity of ciliary muscle rapidly, cure pseudomyopia in a short time; And for the elongated true myopia of axis oculi, the result of this relaxation force long term reduces the crystalline lens diopter, and form a kind of unsettled " false facing " state, if continue to keep, this relaxation force just and then act on eyeball, axis oculi is shortened gradually, recover it and face state, fundamentally cure true myopia.Because returning mirror, this vision can directly impel the muscle of eyes self to regulate, not only reach ciliary muscle easily and regulate this effect in the other direction, but also the opposite direction amplitude of accommodation of may command ciliary muscle, so for different myopic degrees and different look object distance from, can select suitable correction intensity for use by rotating lens frame (3).

Two eyeglasses also can be selected the wedge of the different angles of wedge respectively for use, and all placements inwardly of a thick side, but need to guarantee that the angle in the vertical vertical plane of two eyeglasses equates.This moment, so also different to two the amplitude of accommodation, this kind situation was applicable to two different patients of myopic degree because the angle in the horizontal vertical plane of two eyeglasses is unequal.For the patient who is difficult to remove glasses, also can under the situation of not removing original near-sighted glasses, proofread and correct, but along with the recovery of vision should constantly reduce the number of degrees of near-sighted glasses, proofread and correct to well with bore hole up to trying one's best.

Respectively towards negative scale direction rotation, promptly scale indicatrix (5) is pointed to when bearing scale with two lens frame (3), and the side that the wedge eyeglass is thick is placed towards external symmetry relatively, can be used for treating hypermetropia.

For reducing thickness of glass to looking the distortion of deposits yields, as shown in Figure 2 the middle face also wedge can made is the curved surface wedge of sphere.
