Description

Glasses with dynamic slight defocusing and zooming functions in emmetropic direction
Technical Field
The invention belongs to the field of rehabilitation vision glasses, and particularly relates to glasses with a dynamic slight defocusing zooming function in an emmetropic direction and a vision adjusting device.
Background
In recent years, the incidence of myopia is high, the number of people is more and more, the degree of myopia is more and more deep, the age of myopia patients is smaller and smaller, according to the latest statistics, the myopia rate of myopia patients in China is 3.5 hundred million, the myopia rate of general population in the United states is about one third, in other words, the myopia patients are 20 hundred million all over the world, and the number of myopia patients is continuously increased; the incidence rate of amblyopia of children in China is close to 5 percent, and the number of patients exceeds 2000 ten thousand. In conclusion, juvenile myopia and amblyopia have become social problems worldwide today.
However, the conventional theory of vision adjustment has many problems, which are as follows:
1. the near-far adjustment theory has problems: the clinical trial of the largest billions of people all over the world, namely, students read books in schools when watching a blackboard at a distance and regulating the distance for a plurality of hours every day, but the myopia is still high, because the eye blood supply is insufficient, the asthenopia and the ciliary muscle spasm are easy to generate, and all the distance regulation is invalid.
2. Ignoring the view angle: in addition to the visual chart, the visual angle is almost never mentioned in the control chain of eye diseases such as myopia. Almost all the eye disease treatment instruments such as the near-vision myopia sold in the market have the visual angle of the luminous viewpoint larger than 150 minutes, almost all the myopia patients have developed the habit of only seeing a large visual angle and not seeing a small visual angle, the larger the visual angle is, the larger the covered retina area is, more visual cells are inhibited, and the vision is degraded.
3. The deficiency of visual three-linkage: the visual system should be five-linkage, but the theoretical basis of the existing binocular fusion instrument for treating myopia is three-linkage, only the set change has no visual angle change, and the brain does not support linkage and adjustment when being compared and judged with empirical data.
4. The treatment of amblyopia lacks general concepts: the treatment process of amblyopia only focuses on the activation of the visual cells, and does not consider how the activated visual cells and the optic nerve cells work continuously and are not inhibited or used any more, and the activated visual cells have to enter the inhibiting state again because of insufficient blood supply.
5. No corresponding intervention of form deprivation was made: since only the fovea of the retina receives sufficient visual stimulation when reading at close distances, while most others lack sufficient stimulation to be less active, modern medicine does not intervene accordingly.
6. The existing glasses are not used properly: a near vision lens may cause distant objects to become more distant from the focal image plane back to be imaged on the retina. However, when people wear the myopia glasses to see near objects, the imaging focal plane of the near objects falls behind the retina to generate new defocus, in order to see the near objects, the brain and the retina adaptively adjust the eyeball, the eyeball is gradually lengthened backwards, the eyeball is lengthened, and then when people look for the far objects again, the image falls in front of the retina again, the eyes are unclear again, and the glasses need to be fitted again, so that the reciprocating is carried out, the improvement of the spectacle power and the reduction of the eye vision are accelerated, and meanwhile, the risk of eye diseases such as retinal detachment, glaucoma and retinopathy of wearers is increased.
As is well known, any treatment method for recovering true myopia vision is intended to restore the axial length of an eyeball to an emmetropic state and restore the accommodative function of the eyeball to the original elasticity, and any treatment method is useless for restoring the axial length of the eyeball to the emmetropic state due to the negative effects of the glasses on the definition of the near object imaging focal plane, maintaining the original axial length and preventing the eyeball from being restored during the treatment.
The Chinese patent application CN101156814B discloses a pair of glasses for treating and assisting eye diseases such as myopia and the like and a preparation method thereof, the length of an eye axis is gradually led to be normal through defocusing of the glasses in the front-view direction on the basis of a common window area, but the glasses need to be continuously replaced, the reduction degree is too high each time, and the force for shortening the eye axis in the front-view process can be weakened; each time the degree is reduced to be too small, the cost caused by changing the glasses for many times is increased, and the speed of changing the glasses can never keep pace with the speed of changing the glasses which is actually needed.
Chinese invention patent application CN100562776 discloses a pair of glasses; the chinese utility model patent application CN 204595363U discloses a zoom lens set that can be arbitrarily changed; chinese patent application CN100476513 discloses a variable focal length spectacles; chinese patent application CN101506714 discloses a variable focus lens and spectacles; chinese utility model patent application CN2246302 discloses a spectacle lens with adjustable power; chinese utility model patent application CN204154982U discloses a head-mounted 3D glasses used on a large-screen mobile phone. The above patent application adjusts the lens power according to the user's current visual perception through different technical means to achieve the purpose of correcting eyesight, however, the non-professional user adjusts the lens power, the problems of over-correction, induction of eyeball increasing power and the like easily occur, and the adjusted lens power easily changes due to the change of conditions (vibration, pressure, temperature, reduction of battery power, leakage and the like).
Chinese utility model patent application CN201046185 discloses a myopia treatment vision adjusting device, gradually guiding the length of the eye axis to be normal through the defocusing of the decreasing degree glasses in the direction of the emmetropia, but describing the action position and the action mechanism improperly in the specification
The Chinese patent application CN 104850138A discloses an intelligent control zooming training device, which realizes the optimization and perfection of the overall visual function with a brain visual system as the core by upgrading the clear visual ability in an original focusing state to the clear visual ability in an out-of-focus state, can improve the naked eye vision, but also has the worry of increasing the computer optometry.
The Chinese patent application CN 105213158A discloses a visual function optimization training control system and a control method thereof, wherein training data are recorded by a microcomputer in the whole course, and an adjustment scheme is given through analysis, so that the practicability and effectiveness of visual optimization training are greatly improved, but the method for connecting the output end of the training equipment with the input end of a distance measuring device and the input end of a shooting device is questionable, and sonar is mainly used underwater, and whether the distance measurement suitable for land daily life is unknown.
Chinese patent application CN101001588B discloses a device for treating eyes using a biomimetic method, chinese patent application CN101292928B discloses a therapeutic apparatus for myopia and amblyopia capable of adjusting brightness of relative luminous viewpoints of left and right eyes respectively, and chinese patent application CN101969895B discloses an eye disease prevention and treatment device having a plurality of visual mark points. The eye yoga vision enhancement instrument of the three patents increases seven strength reserves of a visual system (eyeball circulation power reserve, intraocular muscle regulation power reserve, sclera development activity reserve, sclera tensile tension reserve, extraocular muscle searching capacity gathering capacity positioning capacity reserve, visual cell activity reserve and eye brain communication capacity reserve) through eight kinds of bionic training (omnibearing eye yoga movement, five-linkage binocular fusion, peripheral visual field stimulation training, visual acuity training, super fine visual acuity training, two-eye flicker training, closed eye visual light training and point-matchable electronic plum blossom needle), restores three necessary conditions (refraction interstitial transparency, eye axis length matching with refractive power and normal visual passage) for maintaining healthy eyes, and opens a door capable of curing hyperopia, astigmatism, amblyopia, refraction aberration and strabismus from the bottom layer forming the etiology. However, the disadvantage is that in order to improve the vision smoothly, the glasses with low degree need to be worn to cooperate with the instrument to do the assistant training of the distance walking and the near walking for orthoptic defocusing, but the distance walking and the near walking are difficult to standardize or insist, so that the curative effect is not constant.

Example 2
As shown in fig. 4-5, 15-18: the structure of example 2 is substantially similar to that of example 1, with the difference that: embodiment 1 is a rotary zoom, embodiment 2 is a cantilever zoom, and since there is no limitation of the lens barrel, the field of view of embodiment 2 is very wide, approaching the normal field of view of human.

A more preferred option in examples 1 and 2 is,
for myopia, the zoom lens group far away from eyeball, when moving lens 11 is negative lens, end face lens 10 is positive lens, moving lens edge is flat lens, so when seeing through the positive normal use eye of mirror group, on the basis of forming the dynamic slight out-of-focus zoom function of emmetropia direction at the optical center, the peripheral field of vision is that the peripheral field of vision object image falls on the retina inboard (except the field of equatorial peripheral vision) at this moment of the flat lens part of positive lens plus concave lens, and this phenomenon can form bigger power of shortening the axis of the eye with the dynamic slight out-of-focus zoom of retina central concave emmetropia direction together.
For the hyperopia, since the near-eye segment of the moving lens is used, the flat lens portion around the concave lens is not visible through the replacement lens 12 near the eyeball having a smaller diameter, and thus the treatment of the hyperopia is not affected. When the movable lens is a positive lens and the end lens is a negative lens, the edge of the movable lens is a flat lens, so that when a normal eye is penetrated through the lens group, on the basis of forming a dynamic slight defocusing zooming function in the emmetropia direction at the optical center, the peripheral vision field is that the peripheral vision field object image falls outside the retina (except for the equatorial peripheral vision field) at the moment of forming the flat lens part at the edge of the negative lens and the positive lens, and the phenomenon and the dynamic slight defocusing zooming in the foveal emmetropia direction at the center of the retina can jointly form larger force for promoting the growth and development of the eye axis.

The eye yoga movement in all directions is from the fact that wild animals need to look around to defend natural enemy eyes, and the movement part is located on the whole eyeball. The rapid searching capability, the gathering capability and the positioning capability of the eyeballs and extraocular muscles can be rapidly recovered through the omnidirectional yoga movement of the eyeballs along with the luminous viewpoints, so that the anterior segment capability of the 'normal visual path' can be recovered; the eye blood circulation is improved, the eye circulation power reserve is enhanced, the supply capacity of nutrient components of each part of the eyeball is improved, and a material basis is provided for the rehabilitation of eyesight; meanwhile, the capability of eliminating daily metabolites of each part of the eyeball is improved, so that 'refraction interstitial transparency' is recovered; stimulating the peripheral visual field at the far and near parts of the eyeground to drive any one of the light-emitting viewpoints at eight directions of the omnibearing eye yoga movement to flicker, wherein the peripheral visual field is stimulated initially, and then the visual axis is rotated by the eyeballs to point to the light-emitting viewpoint, so that the process can simultaneously improve the blood circulation of the peripheral visual fields at the far and near parts of the eyeground, and for myopia, the tensile tension reserve of the sclera is increased to form the force for gradually shortening the visual axis; for hyperopia, the developmental vitality reserve of the sclera is increased, and the axial length of the eye is promoted to gradually approach the emmetropic direction.
Secondly, the five-linkage visual binocular imaging movement is derived from the unique eye using habit of hawk animals, and the movement parts are extraocular muscles, ciliary muscles, pupil sphincters and crystalline lenses. The change of the eye muscle adjustment and the change of the pupil size are driven by the change of the set, the change of the visual angle and the comparison and judgment of the brain and the empirical data. The traditional elasticity and functions of ciliary muscles and crystalline lenses are quickly recovered, the capacity accumulation and the regulation capacity accumulation of eyeballs are increased, the regulation sensitivity of the eyeballs is quickly recovered, the refractive power in the refractive power conforming to the length of the axis of the eye is recovered, conditions are created for conforming the refractive power to the length of the axis of the eye, the pressure of non-conforming length of the axis of the eye and the refractive power is reduced, the double asthenopia formed by rigidity of the ciliary muscles and elongation of the axis of the eye is eliminated, the object image is drawn close to the retina, and a foundation is laid for quick recovery of myopia.
Peripheral visual field stimulation movement comes from the sensitivity of wild animals to peripheral visual field dynamic targets, and the movement part is located in peripheral visual field visual cells and sclera of corresponding part. When a plurality of luminous viewpoints flash simultaneously, the user mainly looks at the central luminous viewpoint or mainly looks at books, computers, televisions and natural scenery, and the flash, rotation and change of the luminous viewpoints of the peripheral vision field are observed by using the residual light, so that the length of the eye axis can be effectively shortened from the optical angle and the mechanical angle, and the object image gradually falls on the retina: wherein, the object image formed by the peripheral visual field stimulation falls to the outer side of the retina near the equator of the peripheral visual field of the eyeball, and in order to see the object image clearly, the diameter of the equator of the eyeball can be effectively increased and the length of the eye axis can be effectively shortened from the optical angle, thereby solving the problem that the length of the eye axis of the modern medicine can not be shortened. More importantly, the peripheral visual field participates in vision, can effectively improve the blood circulation of the sclera part of the peripheral visual field of the eyeball (data show that the sclera and the visual cells of the corresponding part are supplied with blood by the same blood vessels), and for myopia, the tensile tension reserve of the sclera is increased, the force for gradually shortening the axis of the eye is formed, the length of the axis of the eye is gradually shortened, the length of the axis of the eye in the process that the refractive power is consistent with the length of the axis of the eye is recovered, and conditions are created for the refractive power is consistent with the length of the axis of the eye; for hyperopia, the sclera development vitality reserve is increased, the axial length of the eye is promoted to gradually approach towards the emmetropia direction, the axial length of the eye in the process that the refractive power is consistent with the axial length of the eye is recovered, and conditions are created for the consistency of the refractive power and the axial length of the eye.
Vision acuity training and superfine eyesight training, which are derived from the unique eye use habit of hawk animals, and the exercise parts are retina fine visual cells and eye and brain passages. Through the fixation of an infinite number of tiny viewpoints in the luminous viewpoints of the eye yoga vision enhancement instrument, the improvement of the resolving power of a user for watching the sighting target with a small visual angle is facilitated. Meanwhile, the luminous viewpoint can simultaneously activate thousands of visual cells and optic nerve cells once per flash, and compared with the traditional medical method, the luminous viewpoint can improve the working efficiency of the activation of the visual cells and optic nerve cells by hundreds of times and thousands of times, efficiently complete the awakening of retina fine visual cells, is beneficial to the storage of retina vision, can stably promote the retina vision, recovers the middle section capacity of 'normal vision passage', and stably promotes the retina vision of amblyopia or high-degree myopia eyes. Meanwhile, the time of each treatment of amblyopia is greatly shortened, the super fine eyesight training treats amblyopia, and the family fine eyesight training can be free from optical gratings, rear images, beads stringing, pin pricking and the like.
The luminous visual points of the left eye and the right eye alternately flash respectively, the luminous visual points can be used by two eyes of wild animals respectively, and the moving parts are visual cells of weak eyes and the eye and brain passages. Can increase the chances and abilities of the affected eye or the weak eye to participate in training, vision and vision recovery. Meanwhile, in the process that the left and right eye luminous viewpoints alternately flicker, the visual residual of healthy eyes can modulate the visual desire of weak eyes, get through the visual nerve channel, enhance the storage of the eye-brain communication capacity, enhance the compensation capacity and the fusion capacity of the left and right brains, recover the posterior segment capacity of the 'normal' visual channel and rapidly improve the weak eye vision.
And seventhly, eye closing visual training is realized by closing eyes, seeing the sun, charging energy into eyeballs, moving eyeground blood vessels, transmitting the energy of visible light emitted by the instrument to far infrared light converted by eyelid, irradiating the far infrared light to the eyeground through pupils, and utilizing the blood rheology improvement characteristic of the far infrared light to clean garbage in the eyeground blood vessels, improve the blood circulation of eyeground retina, choroid and sclera, and meet the condition of 'eye blood receiving and visual' of traditional Chinese medicine.
