Intelligent control ciliary muscle instrument for training
Technical field
The invention belongs to vision correction healthcare field, more particularly to a kind of intelligent control eyelash suitable for teenager's vision correction
Shape flesh instrument for training.
Background technology
Ciliary muscle is made up of smooth muscle fibers beam, is divided into three parts:Outermost layer is the stringer fiber of front and rear trend, centre
The radiating fibers arranged for diagonal, preceding inner side is circular fiber part, also known as muller fleshes.There is both direction during ciliary muscle contraction
Power work:One power makes apparatus suspensorius lentis forward, inwardly move, the result that mainly circular fiber shrinks;Another
Power is by choroid front portion to front haulage, and this is the result of stringer filament contraction.Previous power makes suspensorium relax, and crystalline lens becomes
Convex, diopter increase embodies lenticular adjustment effect, is conducive to seeing closer object clearly;Latter power makes choroid anterior
Move forward, while scleral spur is pulled to rear.When we focus remote thing, ciliary muscle will be put naturally
Pine, the ligament that crystal is positioned is tensed, and such crystal will become flat and more slim.Lower the focusing ability of crystal, help
We watch remote thing.If seeing nearby, ciliary muscle will shrink, and crystal is thickening.
The near-sighted teenager of growth and development stage is in, incorrect with growing and being accustomed to eye, myopia degree can not
Disconnected to increase, axis oculi can be elongated constantly, and intraocular pressure can also increase.Existing visual function trainer, generally comprises support, special optometry
Disk, sighting target, sighting target guide rail, sighting target controller and optometry disk guide pillar.It is complicated although easy to operate, to effectively releasing near
Depending on the ciliary spasm of eye patient, effect is not highly desirable in terms of making the reduction of crystalline lens convexity.
The content of the invention
It is contemplated that providing a kind of controllable design accuracy in place of overcoming the deficiencies in the prior art, myopia is effectively released
The ciliary spasm of eye patient, makes the reduction of crystalline lens convexity, can effectively prevent, treat pseudo-myopia, esophoria can be corrected again
With the intelligent control ciliary muscle instrument for training of exophoria.
In order to solve the above technical problems, what the present invention was realized in:

When A nearsighted person sees object by near reading range, the light planoconvex lens convergence of object emission, after being focused on through crystalline lens
Image in before retina, image blur is unclear, due to the physiological adaptation function of human eye, eyelash can be adjusted automatically by neural reflex
Shape flesh loosens, and ciliary muscle flesh ring is become big, and ciliary ligament traction crystalline lens, crystalline lens tension force reduces, and thinning, convexity diminishes, and makes
Retina is moved to after picture point into more visible image.
The present invention is compounded to form complex optics by particular curvature prism and convex lens, can exhale near objects
The light come becomes that parallel rays is pleasing to the eye, alleviates the set effect of two, so as to drive regulative mode, eliminates false near
Depending on, and control the development of true myopia.It is small recessed that the present invention had both met the center that retina correspondence is changed into macula retinae area
Correspondence can be changed by prism and convex lens again sees near with regulation and set at the moment, by mist depending on forcing eyelash with reversely regulation
Shape muscular relaxation, crystal diopter reduces to recover eyesight.
Whether the present invention first has strabismus, eye movement, a binocular vision function when specifically used from optometry, Binocular vison intuition,
Eyes apparent motion, eyes visual center and the inspection gone out in terms of photoimaging are started with, as the case may be personalized correction solution, will
Retina correspondence changes into the small recessed correspondence in center in macula retinae area, during mirror is worn, according to child whether have strabismus and
The change of strabismus, vision correction situation periodic replacement eyeglass, are used for a long time on vision without influence, are finally reached correction strabismus, control
System and reduction diopter, lift the effect of UCVA.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
