Embodiment
People's (beyond 5 meters) eyes axis oculi when seeing far away is parallel, and Diopter accommodation loosens, and pupil amplifies.When seeing near, (within 40CM) eyes axis oculi inwardly rotates simultaneously and sight line is being intersected by depending on object location, and Diopter accommodation makes sight line point of intersection be formed image clearly on the retina by depending on thing, and pupil also does and reduces adjustment accordingly simultaneously.These three kinds of visual performances almost simultaneously completed, are referred to as " binocular vision three links ".
Three through transports of eye are moved: when eyes regulate, eye respectively organizes occurred coordination phenomenon.During adjustment, ciliary muscle contraction, crystal becomes convex, and diopter increases, and focus is fallen within retina.During adjustment, eyes have inward turning, increase converge like the spokes of a wheel at the hub amount, and along with myosis, the degree of depth of focus can be made like this to increase, and then eyes carry out the control of regulated quantity according to the degree of depth of focus, and such eyes just can see clearly near object.Alternatively become like this: regulate and increase-> converge like the spokes of a wheel at the hub increase-> pupil-> the depth of focus-> regulated quantity that rises that diminishes and control.Eyes regulation mechanism is: see near, and-------crystal suspensorium relaxes, and-----crystal elasticity deformation------produces adjustment human body principal visual function, and (near time far away when depending on thing being often, the main mutual coordinated movement of various economic factors by intraocular musculus rectus lateralis realizes its function to-ciliary muscle contraction.
The prerequisite realizing best refractive status is that eyes have strong visual performance, and the power of visual performance exactly by binocular vision three link embody.The rule that ophthalmic refractive state is grown is: by long sight to facing again to myopia, the process of growth is unstable, and the result of growth is irreversible.It is that refractive status was grown slow presenting and grown delayed that people finally becomes long sight, and becoming myopia is that refractive status is grown and too fastly presented advanced growth.Recently there is scholar to point out, see and closely cause near-sighted change to be also a kind of special circumstances of form deprivation.The accommodative excess that " depending near " causes is nervous, and can make to see that reaction far away is slack-off, this " distal response is slack-off " just shows as near-sighted phenomenon or be called pseudo-myopia.And then to propose the adjustment of eye when seeing near be not the reason causing axial myopia, but when seeing near, regulatory function lags behind consolidation function, thus image blur on the retina, elongated and become true myopia in order to see clearly the eyeball forming compensatory.
Grow the via effect innovation theory of doctor according to world's ophthalmology authority-William lotus thunder show shellfish, with the functional contact lenses of Myopia out of focus type of scientific design, allow light therethrough through hole inject cornea, crystalline lens focuses on retina, similar telescope principle.Reduce the interlock of ciliary muscle and pupil when looking near, make eyes antimetropia thing be in relaxation state for a long time, asthenopic generation can be reduced.Meanwhile, the number of degrees capable of preventing myopia are deepened, replace pupillary function, training ciliary muscle focuses ability, replace the spectacles of less than 400 degree, the number of degrees are made up with adjustment force, improve pseudo-myopia person, the width that common " blink " problem also can lower harmful light such as TV, multimedia screen is penetrated and stimulates, and realizes reducing eye strain and anxiety, improves the object of eyesight.
In sum, principle as can be seen from binocular vision three links: viewed from eyes during object, eye muscle and pupil move all at the same time, we make a through hole eyeglass according to the ciliary muscle in eye structure principle and iris joint-action mechanism principle and place at the moment, but also varying in size according to eye pupil, the eyeglass of design different size pore size matches with it, when eye muscle and pupil all need not be moved, allow eyes be in relaxation state always and just can see object clearly, so just can reduce asthenopic generation, and keep the visual field clearly in this case, effectively can prevent and solve because of the relevant issues that modulability is tired and optical defocus phenomenon occurs, to reach the object realizing near-sighted prevention and control.
