Description
Technical field
It the utility model is related to a kind of spectacles, and in particular to one kind, which solves retina image-forming defocus, prevents axis oculi from elongating
Myopia recovery glasses.
Background technology
Myopia refers to eye when without using regulation, after the dioptric system flexion that parallel rays passes through eye, focus fall regarding
A kind of refractive status before nethike embrane.So myopia can not see the target in a distant place clearly, if target is gradually shifted near to eye, sent
Light eye is scattered in a certain degree of, form focus and be just moved back, when object moves closer to certain point at the moment.This point
Nearer from the position of eye, the degree of myopia is deeper.
The reason for myopia occurs is mostly that eyeball antero posterior axis is long（Referred to as axial myopia）, it is secondly stronger for the refractive power of eye
（Referred to as bend forthright myopia）.Myopia mostly occurs in adolescence, and inherent cause has certain influence, but its occurrence and development, with
Lighting deficiency, reading posture is improper, and near work, which is relatively waited so long, substantial connection.Most of myopia occurs few in green grass or young crops
Year, deepen year by year in the development growth stage number of degrees, do not develop to after reaching maturity or slower development.Its myopia degree is very
Less more than 6D, degeneration change does not occur for eyeground, and eyesight can be with mirror wildcarding correcting, referred to as simple myopia.Another myopia occurs
It is more early（It can occur between 5~10 years old）, and make much progress, continue to develop after 25 years old, myopia degree up to more than 15D,
Fundus oculi changes are often accompanied by, eyesight is not easy to correct, referred to as degenerative myopia.In addition, traditionally often below 3D myopia is referred to as slightly closely
Depending on 3~6D person is referred to as medium myopia, and more than 6D persons are referred to as high myopia.
When seeing object, light is made video institute by pupil by the adjustment of eye lens the normal eye of standard
Some parts just fall on the center of retina and periphery, so the object seen is than more visible.And the presence of myopia, particularly
The caused myopia because axis oculi elongation, when the reflected light of object produces video by crystalline lens pupil so that video institute
It is in fall in the front of retina, causes video to obscure, it is unintelligible.Near-sighted colony falls when after retina when video, and eyes are
Optimum visual state is adjusted to, axis oculi is from extending back, to cause video to fall on the retina or before retina, and
Caused myopia aggravation, here it is so-called lens-induced myopia.
In near-sighted group, especially teenager, generally use wears the methods of spectacles to correct defects of vision, and defocus is near
After wearing glasses, myopic degree exacerbation is often resulted in, because when being corrected using common eyeglass, work(is adjusted by eyeglass
Can so that fallen by the image of optic center point in central retina, but it is consistent due to the eyeglass number of degrees, and axis oculi
Stretcher strain, so imaging is uniformly to be seated in the circumference of standard, some visual response light are caused to pass through pupil, image
Fall in retina back, cause visual experience bad, therefore cause myopic degree to be deepened.
The method of the myopia correction of current trend is a lot, but various methods all include the defects of can not each overcoming,
Haplopia away from eyeglass correction regard it is remote and regarding it is remote when all use same diopter, degree of fatigue when increase regards near, increase myopic degree；
Progressive multi-focus lens use progressive diopter from regarding far field near reading range, but it is ametropia to be only capable of myopia correction, and
Can not effective retarding myopia intensification.If foveal region of retina regards nest region and keeps clear eyesight, and peripheral retina is kept
It is out of focus, the elongated of eyeball can be caused and then cause myopia development.But traditional myoporthosis eyeglass can not but eliminate myopia and add
Deep stimulus.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the purpose of this utility model be to provide it is a kind of solve retina image-forming from
The characteristics of Jiao prevents the myopia recovery glasses that axis oculi elongates, and has and corrects defects of vision, and recovers eyesight, and prevention axis oculi elongates.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of myopia recovery glasses for solving retina image-forming defocus and preventing axis oculi from elongating, including picture frame and eyeglass, it is described
Center of lens centered on optical region, the center of central optic region is gradually passed to central optic region edge center diopter
Increase, described central refractive power incremental range 0.00D~-8.00D, the outside from central optic region edge to lens edge
Edge optics area's diopter slowly successively decreases with respect to central refractive power, is bent centered on described outward flange optics area diopter incremental range
The incremental range of luminosity subtracts 0.50D~+1.50D.
Described eyeglass is aspherical mirror.
The beneficial effects of the utility model are：
According to human eye retina's image-forming principle, by reducing the design of the lens periphery number of degrees, being incident upon behind retina
Focus move on on retina or front, peripheral visual acuity is also corrected while foveal region of retina eyesight is corrected, prevent eyeball to
The trend grown afterwards, is finally reached the purpose of retarding myopia progression, and have adjusted the side of the visual response light in other directions
To making image be fully seated within the front of retina, enhance visual experience, effectively delay visual impairment.Rectified for different
It is positive to require, using different diopters, have for central optical zone and along the peripheral edge optics area in horizontal meridian direction
Relatively low surface astigmatism.Effectively adolescent myopia can be delayed to deepen.
