Description
Technical field
The present invention relates to a kind of dynamic type vision training apparatus that utilizes prism to implement, it is moderately movable in naturalness particularly to relate to a kind of eyeball that can allow, and then prevents near-sighted number of degrees intensification, and the device that reduces the near-sighted number of degrees.
Background technology
The structure of eyeball is just like a photographing unit, and the intraciliary ciliary muscle of the portion control of crystal thickness of specially water tendering within it allows to accommodation (Accommodation) and allows and see and see that far image can both be clear when near.Then there are six outer eye muscle the eyeball outside, to control oculogyral direction.Six outer eye muscle of each of two have mutual coordination, reach the effect for the treatment of as a target admittedly to watch same direction attentively.Collect (Convergence) in two meetings automatically when seeing nearby, then automatic again abduction (Divergence) when seeing at a distance is towards same target.
The function of this two ophthalmic collection and abduction with the regulatory function of crystalline lens, has complementary and enhanced effect.This is the known fact of ophthalmology medical science.That is, two watch when near can in collection help ciliary muscle contraction and make crystalline lens accommodation thickening make nearly thing clear.And the arms sideward lift of two outer eye muscle when looking far into the distance, the opposite adjusting of loosening that helps ciliary muscle makes the automatic attenuation of crystalline lens, to see clearly at a distance.
Because the prosperity of civilization, in-plant visual task constantly increases, especially some teenager, on the occasion of the period of eyeball development, closely operation excessively for a long time, as do one's homework, read books and periodicals, computer and see TV etc., all make ciliary muscle and two s' the long-time excess shrinkage of medial rectus, become rigid.The rigid meeting of initial stage ciliary muscle is also seen when far away the crystalline lens that becomes fat can't attenuation, before therefore image at a distance can image in nethike embrane, so that sees when far away fuzzyly, thereby forms myopia.
Myopia by its reason that forms, can be divided into refrangibility myopia and axial myopia approximately.Refrangibility myopia be the over-drastic contraction of ciliary muscle to cause crystalline lens too fat, make image drop on that institute causes before the nethike embrane.Axial myopia then is that crystalline lens is normal, forms but cause image not reach nethike embrane owing to axis oculi is oversize.The initial stage of myopia is all by the beginning of refrangibility myopia, for example pseudomyopia.Refrangibility myopia is through after a while, and inside and outside eye muscle still can't do the appropriateness loosening after, that is after the closely operation for a long time, eyeball can be deacclimatized this state gradually and be transformed into axis oculi and be increased gradually, image energy is nearby easier imaged on the nethike embrane, develop into so-called axial myopia.These all are that acquired environment causes, just the myopia that present most of people suffered from.
The reason that myopia can be deepened year by year is because refrangibility myopia and axial myopia, the result of vicious cycle mutually.So, if can be suppressed refrangibility myopia, the axial length that just can make eyeball is excessive increase not, also just can suppress the intensification of axial myopia.
The mankind belong to two forward-looking side by side species, no matter the eyeball of this animal swing sees far or see that closely, all only meeting is inwardly put, just interior collection.In theory, have only and strengthen outer pendulum, just than the parallel lines of sight at a distance eye position of abduction more, the interior collection effect that could the balance height civilization be increased.When eyeball during, can help the increase of accommodation automatically along with the degree of interior collection at interior collection.And the action of abduction then has reverse effect, can help the minimizing of accommodation.This is the known fact of ophthalmology medical science.Therefore can say that long-time over-drastic interior collection and accommodation are the origin causes of formation that myopia takes place and deepens.
General twenty-twenty vision person (people who does not have myopia), also have when closely looking thing, but can cause the formation of myopia why not? this is because the reason of myopia is: " for a long time " multiply by " fixed focal length ", especially near focal length, and two multiplied together caused.The twenty-twenty vision person, because of the less near focal length that is fixed in for a long time, therefore inside and outside eye muscle is very fresh, flexible, does not ossify, so can comfortable seeing far see near.
The eye muscle and the muscle at other place on one's body are identical as the muscle of arm or shank.Motionless as for a long time arm being placed desktop with a fixed posture, just the muscle on the arm can ache, stiff, thereby become dumb.Anti-, arm has just can not cause the aching with stiff of muscle when mobile.Therefore, for the inside and outside eye muscle of eyeball, also be the same reason.Want can be often the conversion focal length and every now and then activity just can not ossify, could pre-myopia prevention.Therefore, prevent that myopia from not needing to cast out fully closely operation, but want when operation closely, also to make inside and outside eye muscle stretching motion flexibly.That is to say, make eyeball can in collection, abduction, accommodation and loosen accommodation, four kinds are moved in the short time exchange freely, are not fixed in a kind of focal length and eye for a long time, just can break the myopia that bad habit caused of " multiply by closely for a long time ".
According to aforesaid principle, this case inventor proposes No. 91116074 patent application of denomination of invention for " dynamic lens vision recovery method and device " in once, wherein dynamically with a prism or convex prism eyes the place ahead at user, repeatedly force the eyeball abduction of user, and then reach the effect of training eyes.Though the method for this case and device can be reached the purpose of training eyeball effectively, still have the space that further to improve, for example say, employed prism or convex prism have the fixed number of degrees in above-mentioned application, therefore for eyeball,, can cause eyeball to strain apace and to relax one's muscles when prism or convex prism when constantly repeatedly shift-in shifts out, to be matched with the variation of the eyeglass number of degrees, therefore be easy to increase the burden of eyeball.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of eyeball that can allow user adjustable prism vision training apparatus of abduction gradually, to overcome aforesaid puzzlement.
Therefore for achieving the above object, the invention provides a kind of adjustable prism vision training apparatus, it includes variable number of degrees prism, be arranged at user eyeball the place ahead, by gradually prismatical by degree of variation and repeat to increase and reduce the prismatical number of degrees and force eyeball to repeat constantly with the progressive mode abduction, and then can draw and loosen the eyeball medial rectus of excess shrinkage, reach the effect of training eyeball.
