Description
Technical field
The invention belongs to the health care technology field, particularly a kind of eyeball muscle that allows is moderately movable under naturalness, and then prevents dynamic lens vision training apparatus and the method thereof that the near-sighted number of degrees are deepened and reduced near-sighted number of degrees person.
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.
Nearly many decades is because the prosperity of civilization increases in-plant visual task.Especially some teenager, on the occasion of the period of eyeball development, early work industry excessively for a long time: as 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, and become rigid.
Initial stage ciliary muscle rigid also seen when far away the crystalline lens that becomes fat can't attenuation, and image at a distance is by before imaging 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 refrangibility myopia beginning (pseudomyopia is exactly an one).Refrangibility myopia is through after a while, and after inside and outside eye muscle still can't do loosening of appropriateness; That is after the early work for a long time industry, eyeball can be deacclimatized this state gradually and is transformed into axis oculi and increase gradually, and image energy is nearby easier imaged on the nethike embrane, develops 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 it is near that the eyeball of this animal swing is seen far, seen, all has only inside pendulum forever, 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.
Does 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: multiply by fixed focal length for a long time, and especially near focal length, two multiplied together are 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, and 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 the early work industry, but want when the early work industry, 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 " multiply by closely for a long time " myopia that caused bad habit caused.This intention just of the present invention.
There are many vision rehabilitation machines in past, and its effect is the motion that focuses on eyeball.Some is to chase bright spot to move with eyes to train outer eye muscle; Some is to see that an object is far and near mobile, trains interior eye muscle.But these all can only reach two eyeballs moving of moving property altogether, and can't reach the action of the outer pendulum of two eyeballs, so effect is unclear.Because when having only two eyeballs to put, can more help loosening of a nearlyer step of ocular accommodation outward.
Clinically: the lengthening speed of its axis oculi of axial myopia person, therefore fast natural rate of growth of cross growing up can be found out on the nethike embrane of optical fundus with ophthalmofundoscope, has semi-moon shaped blue speckle (also being called near-sighted speckle) at Nie's sidepiece of optic disc and occurs.Does but why this lunule only appear at Nie's sidepiece? it inwardly changes owing to the long-time excessive of eyeball, due to promptly interior collection is too of a specified duration.Because optic nerve be positioned at eyeball back utmost point portion and near nasal side, when in the eyeball during collection cornea end rotate toward nasal side, back utmost point portion then rotates toward the ear side, causes Nie's side of optic nerve and eyeball joint to be drawn back, and utmost point portion after the elongation.Therefore, the interior collection effect of eyeball is to cause that axis oculi increases and the former act of violence of Nie's side lunule.
Another shortcoming of the vision rehabilitation machine in past all must transfer to one period regular hour to make great efforts training especially when being the every day rehabilitation, just a little effect can be arranged.But this kind is arduous and boring training, and being most can't be for a long time, the continuing of several months, several years, and rehabilitation person often just gives up halfway in the short time, thus at last this kind rehabilitation machine be regarded as invalid.

The specific embodiment
Dynamic lens vision training apparatus of the present invention and method thereof are described in detail as follows in conjunction with each embodiment and accompanying drawing:
Fig. 1 is the eyeball A that shows common people when seeing near object B, and two eye positions are states of collection in being.But if when placing prism C in the place ahead of eyeball A, then (as shown in Figure 2) put in meeting outward for molten picture in two eye positions.The present invention utilizes this principle and the dynamic lens vision training apparatus and the method thereof that design.
General convex lens D structure is as shown in Figure 3, and the present invention is combined as a whole convex lens D and prism C and constitutes convex prism E; It can be when grinding convex lens, goes out prism C-structure person (as shown in Figure 4) at the side grinding of convex lens D.
The present invention is as datum mark with the relative thicker bottom (Base) of prism, when eyeball is seen near object, be shifted the approaching relatively state in bottom (to call Base in the following text on two groups of prisms, be called Base out during at the state that separates relatively when prism bottom on the contrary) so that put (state as shown in Figure 2) outside the eyeball, and the bottom is towards the below (to call Base down in the following text) and make the ophthalmic collection and go up simultaneously and change.This is because after the mankind enter civilized life, does not have epoch of myopia compared with the older generation, and eyeball active direction when near work is to see inwardly and down mostly, and less have a chance that looks up.Therefore promote the action changeed on the eye muscle with prism " Base down ".
When eyeball was seen object far away, then prism reached replacing of " Base out " with " Base in " and allows outer pendulum of eye muscle and interior the collection.Or take down with " Base in " and prism and to be used alternatingly.
The length of service time depend on this device be used near with or usefulness far away, for example:
The nearly time spent (homework or make computer, use when beating electronic game)
Add the 20 seconds time (when referring to Base in) of prism or convex lens
Take off the 6 seconds time (when referring to Base down) of prism or convex lens
Time spent (seeing TV) far away
Add the 10 seconds time (when referring to Base in) of prism or convex lens
Take off the 6 seconds time (when referring to Base down) of prism or convex lens
Aforementioned about 10 ~ 30 seconds of the time that adds prism or convex lens, when being less than 10 seconds, easily cause dizzy discomfort too soon because of changing; If then the effect of rehabilitation was less more than 30 seconds.
About 5 ~ 20 seconds of the time of taking off.In this period of taking off, inside and outside eye muscle promptly can be got back to the state of contraction, anxiety, so the period can not be oversize, with the effect that reaches the present invention's campaign and loosen.
The change of lens then comprises the number of degrees and position.
The number of degrees: identical prism degree of right and left eyes and convex lens degree.
The added number of degrees should be more when closely seeing.Because when closely seeing in the eyeball angle of collection big when far seeing, so need more prism degree that eyeball is put outward.
When far seeing in the eyeball intensity just little originally, as with too big prism degree the time, can cause the situation that image can't molten meeting.Therefore, the number of degrees of prism and convex lens should be as follows:
Prism degree 4 Δ Diopter ~ 8 Δ Diopter (the simple eye number of degrees)
Convex lens degree+1.0Diopter ~+3.0Diopter (simple eye convex lens degree)
The added number of degrees should be less when far seeing.If prism degree is during less than 3 Δ Diopter, the angle of the outer pendulum of eyeball is too little, and effect is limited; If when prism degree is too big, can cause the phenomenon that multiple image can't fuse, therefore, the number of degrees of prism and convex lens should be as follows:
Prism degree 3 Δ Diopter ~ 8 Δ Diopter (simple eye prism degree)
Convex lens degree+0.25Diopter ~+0.75Diopter (simple eye convex lens degree)
Find that through clinical trial institute adds prismatical size, also should vary with each individual.There is outer loxosis person eye position, and original eyeball is just outer to be put, so can be with more prism degree.And there is interior loxosis person the eye position, and is opposite, uses the smaller prisms degree.This prism degree that varies with each individual is adjusted eyeglass and can be arranged in the spectacle-frame of external hanging type.
The number of degrees of convex lens are between+0.25 Diopter ~+3.0 Diopter, and these number of degrees comprise makes added total number of degrees of time spent.The convex lens number of degrees of the present invention all refer to the simple eye number of degrees, if during the overlapping use of lens, then refer to the number of degrees of simple eye overlapping eyeglass addition.
When closely seeing, the used convex lens number of degrees are many in the time of should far seeing, and the distance of the used number of degrees and object is inversely proportional to.The convex lens number of degrees that in fact the present invention uses, should+0.25 Diopter more than the convex lens degree of optical computing ~+0.75Diopter.So effect that just can have mist to look is to stimulate loosening fully of accommodation power.
