Description

Technical Field

[0001] The invention mainly relates to the field of vision training for improving poor vision and inhibiting myopia progression, in particular to a vision training device and method thereof. Background Art

[0002] As we all know, when the muscle tension of the ciliary muscle responsible for focus adjustment inside the eye is at the most relaxed level physiologically, and distant scenes are focused in front of the central retina, this is defined as myopia, which also causes blurred and decreased vision, resulting in poor vision.

[0003] When people look at a near sight target, the near reflex pathway center in the midbrain is activated, causing three changes:

[0004] (1) Pupil reflex constriction.

[0005] (2) The extraocular muscles that converge the two eyes will contract to maintain the overlap of the visual axes of the two eyes on the same sight mark and avoid diplopia (Hering's law, maintaining binocular single vision).

[0006] (3) The contraction of the ciliary muscle makes the curvature of the lens surface more prominent and the anterior-posterior diameter larger, thereby increasing the accommodation to keep the scene focused on the central retina to obtain a clear vision. When the eyes change to look at the distant sight mark (6 meters or more away), the near reflex pathway center of the midbrain will be suppressed. At this time, the pupils of both eyes, the cohesive extraocular muscles, the ciliary muscles, the curvature of the lens surface and the anterior-posterior diameter will relax and return to normal, and return to the level of physiological relaxation of accommodation when looking at the distance normally.

[0007] The occurrence of acquired myopia is generally caused by excessive reading or close work and the distance is too close. When reading or working at close range for a long time, the sight mark and the image are presented at a relatively close distance. The near reflex pathway center needs to be activated for a long time to increase and maintain the accommodation of both eyes. At this time, the ciliary muscle and the external internal rotation muscle in the eye need to be maintained in a contracted state for a long time. Over time, when looking at distant objects and the reflex pathway center needs to be suppressed, although the eyes no longer converge and the pupils no longer contract, the ciliary muscles may not completely return to a relaxed state from the contracted state, resulting in partial maintenance of the increased accommodation when looking at close objects (accommodative spasm). At this time, although the eyes are looking at the sight mark in the distance, due to the partial maintenance of the increased accommodation, the sight mark and the image are not focused on the retina, resulting in blurred vision and decreased vision and other poor vision.

[0008] The continuous contraction of the ciliary muscle causes accommodative spasm, which is clinically known as pseudomyopia. If this situation continues, it will cause the eye axis to overextend beyond the normal growth rate, resulting in true myopia. When this accommodative spasm is not relaxed, pseudomyopia will continue to exist and continue to aggravate true myopia, which is the high myopia rate of students and the phenomenon that myopia increases by 100 or 200 degrees every year that we often see in clinical practice.

[0009] Looking at close objects for a long time means that the visual axes of both eyes are coherent for a long time. This position requires long-term activation of the extraocular muscles responsible for coherence. According to Sherrington's law, the extraocular muscles responsible for abduction will be inhibited at the same time. Over time, the extraocular muscles responsible for coherence will be over-strengthened (becoming more and more developed and with stronger muscle tension) and easily activated, while the extraocular muscles responsible for abduction will be over-weakened (becoming weaker and with reduced muscle tension), resulting in reduced ability. In this way, the muscle tension of the two groups of antagonistic extraocular muscles will become unbalanced and tend to tilt more towards the coherent direction, which in a vicious cycle assists the occurrence and progression of pseudomyopia and true myopia.

[0010] The myopia treatment and correction methods currently used in clinical practice and on the market include the following categories:

[0011] 1. Physical or invasive means of offsetting myopic refractive error include:

[0012] 1. Wearing myopia spectacle lenses (non-invasive) or contact lenses (invasive).

[0013] The lenses worn to correct refractive errors for myopia are concave lenses, which move the central and peripheral focal points of the central and peripheral images after refraction by the cornea and lens backwards, with the aim of focusing the central image in the distance. However, at the same time, they move the peripheral image in the distance further backwards, thereby aggravating the hyperopic defocus phenomenon in the peripheral retina.

[0014] What is even more unfavorable is that when myopes continue to wear concave lenses to correct myopic refractive errors for close reading and work, the focus of the central and peripheral images will move further back because the central and peripheral images are closer to the eyes, causing hyperopic refractive errors. At this time, the unfocused central and peripheral images will stimulate the visual center of the brain, which has to activate the near reflex pathway center of the midbrain in order to obtain relatively clear images, causing the ciliary muscles to contract (long-term contraction can cause spasm), making the curvature and anterior-posterior diameter of the lens surface larger (continues to increase when the ciliary muscles spasm), and producing increased accommodation (continues to increase when the ciliary muscles spasm) to focus the image, which generally only achieves the focus of the central image, because the focus of the peripheral image requires stronger accommodation to achieve, and at this time, the focus of the central image will move forward to the front of the central retina, causing a new round of myopic refractive errors. Therefore, wearing concave lenses with myopic refractive errors to correct myopia can easily cause and aggravate the occurrence and development of pseudomyopia and true myopia, leading to a rapid increase in the degree of myopia, which can easily increase by one or two hundred degrees in a year.

[0015] 2. OK lenses (invasive), the cornea is easily damaged and infected and scarred, causing permanent vision loss, and keratoconus often occurs.

[0016] 3. The use of atropine to dilate the pupil and paralyze the ciliary muscle (invasive).

[0017] The disadvantages of this type of mydriasis include:

[0018] (1) The dilation of the pupil allows a large amount of peripheral light that was originally blocked by the iris to enter the eyeball, causing light damage to the retina and interference with vision.

[0019] (2) A large amount of light from the sight mark and image enters and refracts through the deviated middle area of ​​the lens. Because the refractive power of the central area of ​​the lens is different from the refractive power of the deviated middle area, astigmatism occurs and blurred sight marks and images are formed.

[0020] (3) Atropine has a long half-life, so the pupils often remain dilated for about 2-3 weeks after taking the drug, causing many problems, including photophobia.

[0021] In addition, atropine is toxic and has side effects, such as accelerated heartbeat, fever, dry eyes and mouth. Long-term use can easily cause harmful ultraviolet rays to enter the eyeball, causing retinal and macular degeneration. Therefore, the concentration used in the past years has been decreasing significantly, but the toxicity remains and the effect is not significant. The toxicity of the latest ultra-low concentration atropine of 0.01% remains to be observed, but the treatment effect is not ideal.

[0022] 4. Laser corrective surgery (invasive, including removal of corneal tissue) is not suitable for under-developed eyes under 18 years old.

[0023] Surgery often causes glare and corneal dryness, and can also cause infection. Myopia will rebound over time after surgery, increasing the risk of retinal holes and detachment.

[0024] 5. Massage, eye exercises, etc.

[0025] 6. Acupuncture (invasive)

[0026] 7. Steam hot compress (invasive)

[0027] 8. Chinese medicine for improving eyesight (invasive)

[0028] Methods 5-8 mentioned above have been clinically proven to be ineffective and lack scientific theoretical basis and explanation.

[0029] 2. In addition to the above-mentioned physical or invasive methods of offsetting myopic refractive error, existing methods of visual acuity training to offset myopic refractive error include the following:

[0030] 1. The common practice is to look back and forth at the sight mark in front and the thumb or finger placed in front. Another common way is to look at the thumb or finger or similar sight mark moving back and forth, such as a pen, ruler, etc. Some training centers use a near and far point training device for this operation, where the sight mark moves away quickly and then moves back quickly (this machine will produce obvious noise that affects the trainee).

[0031] What they have in common is that the sight mark moves back and forth at a fixed distance. When the sight mark moves far away, it is hoped that the distance between the sight mark and the eyes can be used to completely relax the eye's accommodation. However, in fact, the sight mark that is far away is still on the center line, so both eyes have to use the adducted extraocular muscles to maintain single vision, resulting in the inability to completely relax the accommodation; when the sight mark returns to the eyes quickly, this is the same as reading a book, which is the same as guiding the increase of accommodation effect. Therefore, these near and far point training methods not only cannot effectively relax accommodation, but when the eyes look at the near sight mark, they are training to increase accommodation and can produce accommodation spasm.

[0032] 2. The eye movement training promoted by hospitals, optometry shops, vision training centers, etc. is that both eyes move in one direction at the same time. For example, when both eyes look to the right at the same time, the right eye is abducted and the left eye is adducted. When both eyes look to the lower left, the right eye is adducted downward and the left eye is abducted downward. The adducted eye, especially the eye that is adducted downward, may activate the near reflex pathway center and cause an increase in accommodation, while strengthening the medial rectus and superior oblique muscles that increase myopia. Therefore, this type of training can cause an increase in accommodation and is not conducive to weakening the medial rectus and superior oblique muscles that increase myopia by at least having one eye adducted downward.

[0033] 3. Other sight mark training uses sight marks to move in different directions in front of the visual field. When the sight mark moves in circles (shapes such as 0, ∞, 8, etc.), the eyeballs will move inward. This eye movement is a purposeless method. When the eyes focus on the sight mark, the ciliary muscles of each eye need to contract. When one eye is abducted and the other eye is adducted, the ciliary muscle of the adducted eye can be contracted. In both cases, binocular or monocular sight marks can cause an increase in accommodation.

[0034] The above three items are all bad and wrong training methods. Instead of reducing, they will maintain or increase the contraction of the ciliary muscle, leading to the maintenance of accommodation and even spasm, causing the maintenance or increase of pseudo-or true myopia. Therefore, they cannot achieve the purpose of slowing down or reducing myopia and improving vision, and are not advisable. Summary of the invention

[0035] Based on the formation of myopia, the present invention has developed a set of new and unique devices and systematic training methods for its development, the purpose of which is to intervene in the poor vision caused by myopia at an early stage to restore and maintain peak vision.

[0096] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the following is a brief introduction to the drawings required for the description of the embodiments. Obviously, the drawings described below are only some examples or embodiments of the present application. For ordinary technicians in this field, the present application can also be applied to other similar scenarios based on these drawings without creative work. Unless it is obvious from the language environment or otherwise explained, the same reference numerals in the figures represent the same structure or operation.

[0097] As shown in this application and claims, unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not refer to the singular and may also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0098] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so that once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0099] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0100] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0101] In addition, it should be noted that the use of words such as "first" and "second" to define components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above words have no special meaning and cannot be understood as limiting the scope of protection of this application. In addition, although the terms used in this application are selected from well-known and commonly used terms, some terms mentioned in the specification of this application may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article. In addition, it is required to understand this application not only by the actual terms used, but also by the meaning implied by each term.

[0102] Flowcharts are used in the present application to illustrate the operations performed by the system according to the embodiments of the present application. It should be understood that the preceding or following operations are not necessarily performed accurately in order. On the contrary, various steps may be processed in reverse order or simultaneously. At the same time, other operations may be added to these processes, or one or more operations may be removed from these processes.

[0103] The present invention adopts a method of binocular isolation and training, and uses a training display interface similar to a grid during training. The technical solution of this training is described as follows:

[0104] 1. Use specially designed partitions to divide the common visual field and visual range of both eyes into independent visual fields and visual ranges for each eye, so that each eye cannot see the visual mark and visual field of the other eye.

[0105] 2. Divide the monocular visual field into a "grid" shape, and select the upper and lower temporal quadrants as the visual field that is beneficial for training.

[0106] Briefly explain that in the present invention, the forward field of view of a single eyeball and the range of the visual axis during eyeball rotation are both defined in the shape of a "field" character. Then, the relative position of the visual target in the "field" character visual field will determine the relative position of the visual axis within the "field" character range after the eyeball rotates. Generally, when the eyes are in the primary position, the visual axis falls on the center point of the "field" character grid. According to Hering's law, the brain will move the visual axes of both eyes to overlap on the visual target. When the visual target is at a distance of 6 meters or more, the two eyes do not need to converge or diverge because the visual target in space is located directly in front of the visual axes of the eyeballs. When the visual target is at a short distance, less than 6 meters, the two eyes need to converge to make the visual axes of both eyes overlap on the visual target. At this time, the brain will activate the near reflex pathway center in the midbrain to require the two eyes to converge and move so that the visual axes are directly facing the visual target. At the same time, the ciliary muscle will contract to change the curvature and anteroposterior diameter of the lens to increase accommodation for focusing on this relatively close visual target near the eyeball, and the pupil will contract to reduce the influence of peripheral residual light.

[0107] In this case, the central training visual target at certain positions within the "field" character range will lead to the occurrence of poor vision and myopia:

[0108] Now take a common example of a child reading a book with his head down. His two eyes move downward and inward to make the visual axes of both eyes overlap on the visual target to be read. The position of the visual target is on the nasal side and the lower side within the "field" character range. For the right eye, it moves to the lower left grid of the "field" character, and for the left eye, it is the lower right grid. The visual axes of both eyes need to turn towards the nasal side and the lower side, so the visual axes of both eyes need to internally rotate and turn downward to meet the needs of observing the visual target and reading. At this time, the medial rectus muscle, inferior rectus muscle, and superior oblique muscle contract; the lateral rectus muscle, superior rectus muscle, and inferior oblique muscle relax. The function of the near reflex pathway will cause the ciliary muscles of the two eyes of this child reading a book with his head down to contract and the accommodation to increase. When looking at a distance again, the function of the near reflex pathway is no longer needed, and the ciliary muscle and accommodation should fully recover from the tense state to the original relaxed state. However, after long-term and frequent repetitive close observations and readings, the ciliary muscle and accommodation often do not fully recover to the original relaxed state, resulting in the common occurrence of pseudo-myopia and true myopia.

[0109] It can be seen that when the visual target is on the nasal side within the "field" character range, the visual axes of both eyes need to turn towards the nasal side to achieve binocular single vision (Hering's law). This internal rotation action requires the synchronous contraction of the medial rectus muscle and the relaxation of the lateral rectus muscle to achieve the effect of simultaneous internal rotation of the eye axes of both eyes. To achieve the effect of internal rotation, the brain needs to activate the near reflex pathway center, and at the same time cause the ciliary muscle to contract and the accommodation to increase. Therefore, the position of the visual target on the nasal side of a "field" character is not good, and for a person with pseudo-myopia or true myopia, this situation is even worse because it will cause the activation of the near reflex pathway, resulting in internal rotation movement, ciliary muscle contraction, and increased accommodation, which are exactly what we need to avoid.

[0110] Therefore, the eye axis should avoid entering the nasal side, especially the space below the nose, which needs to be avoided. The temporal space is the best because the medial rectus, superior oblique and inferior oblique muscles do not need to be used when the eye axis moves to this area. Therefore, the visual field range that is beneficial for training is selected in the upper and lower quadrants of the temporal side of the "field grid".

[0111] Therefore, the range description of the Tianzi grid is a more suitable training display interface.

[0112] According to the above description which is beneficial to vision training, the appearance of the Tianzi grid training sight mark in a special position of the visual field, corresponding to the upper and lower quadrants on the temporal side of the "Tianzi grid", can achieve a beneficial training effect.

[0113] 3. On this basis, the present invention trains the specific moving direction of the sight mark (coordinated with the main movement direction and angle of the specific extraocular muscles to be trained, and the application of Hering's law and Sherrington's law).

[0114] The training guides both eyes to make abduction eye movements toward the temporal side at the same time by moving the sight mark, while suppressing the need for convergence movement. Therefore, the brain needs to suppress the activation of the near reflex pathway center in the midbrain, thereby increasing the contraction spasm of the ciliary muscles and the adjustment of the lens in pseudo- and true myopia eyes, giving them a chance to return to normal.

[0115] 4. Targeted guidance and training reverse integration (application of Hering's law and Sherrington's law)

[0116] If we simply rely on a monocular sight mark to be in the temporal quadrant of the monocular "grid" visual field for training, the specific extraocular muscles of this eye, such as the lateral rectus, superior rectus, and inferior rectus, can be properly trained. According to Hering's law, the medial rectus, superior oblique, and inferior oblique muscles of the other eye will be strengthened at the same time. Therefore, relying on a monocular sight mark for training cannot maximize the maintenance of the center of the inhibition of the near reflex pathway, nor can it most efficiently strengthen the abduction extraocular muscles and weaken the cohesion extraocular muscles at the same time.

[0117] Therefore, during training, we provide two similar monocular sight marks at the same time, and the distance between the two sight marks is not less than the pupil distance of the first eye position. After using the visual processing center of the brain to sense the respective sight marks collected by the two eyes, they will be merged together to obtain the binocular single vision effect, which can simultaneously increase the inhibition of near reflex pathway central activation, relax the ciliary muscle from the contraction and spasm state, restore the anterior-posterior diameter of the lens from the enlarged state to normal, and at the same time strengthen the abductor extraocular muscles and weaken the cohesion extraocular muscles.

[0118] 5. Formation and maintenance of specific 3D stereoscopic sight marks (application of Hering's law and Sherrington's law)

[0119] The same type of sight mark provided to each of the two monocular eyes may be specially designed to have complementary differences. In this case, after the visual processing center of the brain senses the sight marks collected by the two monocular eyes, it will be easy to fuse them together to obtain the 3D stereoscopic sight mark effect of binocular single vision. The 3D stereoscopic sight mark and vision will feedback greatly enhance the inhibition of the near reflex pathway center, strengthen the abduction extraocular muscles and weaken the cohesion extraocular muscles, and achieve the effect of eliminating ciliary muscle spasm and relaxing accommodation.

[0120] There are three advanced levels of binocular single vision, from the first level where the brain senses that both macula see the same visual mark at the same time, to the second level where the brain fuses the same visual mark seen by both eyes and maintains the fusion, to the third level where the brain fuses the same visual mark seen by both eyes into a stereoscopic visual mark and maintains the stereoscopic fusion. The three training methods mentioned in 3 to 5 above can inclusively train binocular single vision to reach different levels of trainees.

[0121] All three training methods require the brain's visual center to use the reverse fusion mechanism to achieve binocular single vision. Since these training methods are training and increasing the ability of reverse fusion (easier to perform reverse fusion) and range (for example: the reverse range is improved from 0-40mm to 0-50mm) at the same time, the purpose of training will be achieved and strengthened.

[0122] In addition, in terms of training sight marks, the present invention also specifically provides:

[0123] 1. Training various types of conversion of sight signs (images, text, numbers, etc.)

[0124] 2. Train the special presentation changes and forms of visual indicators (size, proportion, color changes, virtual and real contours, etc.).

[0125] 3. Training the display time of the sight mark (how long it lasts)

[0126] 4. Train the static and dynamic visual indicators (dynamic, static, and the integration of static and dynamic into mosaics).

[0127] Because of the natural need and tendency of binocular single vision, the brain will statically fuse the similar visual marks of the two eyes (when the visual marks are stationary) or dynamically fuse (when the visual marks move, the brain's slow tracking mechanism needs to be used). Therefore, the visual marks can be presented in static, dynamic and mixed ways to achieve a stimulating effect.

[0128] The above regulations for training sight marks 1 to 4 are partly intended to avoid the "Trexler vanishing effect" to avoid visual fatigue, maintain training concentration, and prolong the stimulation time. This can increase the inhibition of the near reflex pathway center, strengthen the abductor extraocular muscles and weaken the cohesion extraocular muscles, thereby achieving the effect of eliminating ciliary muscle spasm and relaxing accommodation.

[0129] On this basis, you can also design a series of training sight signs that are related in meaning, or coordinate with audio to create story elements between the sight signs, which can form associative elements and compose logical plots or scenes.

[0130] The above training sight mark content and presentation method can achieve continuous attraction, concentration, interactivity, fun and education. It can also achieve the most efficient inhibition of the near reflex pathway center with the most economical time cost, strengthen the abductor extraocular muscles and weaken the cohesive extraocular muscles, eliminate ciliary muscle spasm, and relax accommodation.

[0131] The following is combined with Figure 1 , 2 , introduces the composition of the training device of the present invention.

[0132] The training device comprises a binocular visual field separation device 100 and a display screen 200, wherein the former is used to separate the binocular visual field into independent visual field areas of each eye, and the latter is used to provide movable training sight marks for each eye in the independent visual field areas.

[0133] The binocular visual field separation device 100 includes a double partition 1, which is composed of two partitions with one side open and opposite sides connected and at a certain angle. The size of each partition is: the bottom side length is about 42 cm (between 40 cm and 45 cm, not limited to this length range), and the height range is about 15 cm to 45 cm (not limited to this height range, determined according to the height of the display screen 200). The color of the double partition 1 is matte carbon black. The opposite sides connected constitute the training side 6, and the open side constitutes the near-screen side 3, which is used to approach the display screen 200. And the double partition 100 can be folded to adjust the angle between the two partitions.

[0134] Figure 2 A preferred embodiment shown illustrates the structure of an adjustment unit 5, which is arranged between two partitions on the near-screen side 3, and includes an adjustment knob 51 and an adjustment telescopic bracket 52, wherein the adjustment telescopic bracket 52 can telescopically connect the two partitions and can be telescopically adjusted by the adjustment knob 51 arranged thereon, thereby adjusting the angle between the two partitions.

[0135] In order to achieve a more comfortable training effect, the connection point of the double partitions 1 of the binocular visual field separation device 100 is the training side 6, that is, close to the head and face of the trainee, and is designed to be a curved surface that conforms to the human facial contour.

[0136] The open end of the double partition 1 forms a near-screen side 3, that is, close to the display screen 200, and cooperates with the opening size adjustable knob 51. When in use, it is adjusted according to the pupil distance of the trainee's eyes in the first eye position, so that the pupil distance of the two eyes during training is not less than the pupil distance in the first eye position. In addition, a non-slip bottom edge 2 is used to firmly place the double partition 1 on a flat desktop. And a detachable forehead support 7 or chin support 8 is used for the comfort of the trainee.

[0137] This double partition 100 is placed between the display screen 200 and the trainee's eyes, which can prevent the above two unfavorable factors from being mentioned above. Through the use of the double partition, when each eye looks at the sight mark, it will not be attracted or disturbed by the sight mark in the opposite visual field. Through the above double partition design, according to the different pupil distances of the trainees, the size of the double partition opening will be adjusted to match his pupil distance, thus avoiding the appearance of the nasal visual field of each eye, and achieving the training purpose of making the sight mark appear only in the temporal visual field that is beneficial to the trainee.

[0138] This is described in further detail below.

[0139] Figure 2 The schematic diagram of the combination of the partition device 100 and the display screen 200 of the present invention is further illustrated. The display screen 200 presents two grids, the near-screen side 3 of the partition device 100 is close to the surface of the display screen 200, and the partition device 100 divides the entire display screen into the display screens 200 on both sides and the shielding area 4 in the middle. The central training sight mark 300 of the display screen 200 moves according to a certain rule, and the trainee on the training side 6 observes the moving track of the central training sight mark 300 to achieve the training effect.

[0140] When the central training sight mark 300 moves on the display screen 200, the trainee's observation is described as follows:

[0141] 1. Special position of the central training sight mark 300

[0142] (1) The quadrant visual field formed by the X-axis and Y-axis: The role of the central training sight mark in the quadrant

[0143] Coordinate position and application of the selective central training target 300. When both eyes are looking straight ahead in the primary position, the interpupillary distance is exactly the distance between the pupils when the eyes are neither converging nor diverging. At this time, the coordinates of the central training target are exactly at the center point of a "field" - shaped visual field quadrant. The Y - axis passing through the center point defines the nasal and temporal quadrant visual field ranges. The nasal quadrant visual field range is likely to trigger the near - reflex pathway. The X - axis passing through the center point defines the upper and lower quadrant visual field ranges. The lower nasal quadrant visual field range is the most likely to trigger the near - reflex pathway. Based on the "most favorable quadrant visual field ranges for training are the upper and lower temporal quadrants" mentioned in the favorable position of the above - mentioned "field grid" ( Figure 2 the directions of the four diagonal arrows in the display screen 200), for the trainee, the first and fourth quadrants of his right eye, and the second and third quadrants of his left eye, are the quadrant visual field ranges most favorable for vision training. Therefore, the central training target we adopt will only appear in these ranges. Other quadrants are not used because we want to maximize the strengthening of the three extraocular muscles, namely the lateral rectus, superior rectus, and inferior rectus muscles, while avoiding activating the near - reflex pathway center.

[0144] (2) Adjust the starting position of the central training target to correspond to the position of the trainee's eyes

[0145] Because some people have latent strabismus, there may be horizontal (left - right) or vertical (up - down) deviations between the left and right eyes. The most affected deviation is the vertical deviation. Even a small deviation may cause visual interference. So there is an operation function to adjust and correct the position of the target before training to bring the eye axes of both eyes to a state and position where the deviation is neutralized, so that the left and right eyes are initially in a relatively neutral state and position. When the pupils of the trainee's both eyes are at the most accurate training starting point relative to the X - axis and Y - axis, the deviations caused by factors such as the trainer's head not being straight and latent strabismus are eliminated, avoiding the adverse interference caused by the deviations of both eyes on the horizontal and vertical lines respectively.

[0146] (3) The distance between the central training target and the trainee

[0147] The distance between the central training target and the trainee is adjusted according to the type of display. For the displays of general computers and tablet computers, it is maintained at no less than 45 cm; when using a TV or a large projection screen, it is based on the normal viewing distance.

[0148] 2. Specific moving directions and trajectories of the central training target

[0149] (1) When relative to the primary position of the eyes, the angle and trajectory of the moving direction of the central training target (cooperating with the main movement directions and angles of the specific extraocular muscles to be trained, and the application of Hering's law and Sherrington's law).

[0150] The contact points of the extraocular muscles and the eyeball have a relatively fixed positional relationship. The contact points of the medial rectus, lateral rectus, superior rectus and inferior rectus with the eyeball are all in front of the eyeball equator. The contact points of the superior oblique and inferior oblique muscles with the eyeball are all behind the eyeball equator. There is also a relatively fixed angle between the extraocular muscles and the visual axis. In the first eye position, the angle of the superior oblique and inferior oblique muscles relative to the visual axis is 51°, while the angle of the superior and inferior rectus muscles relative to the visual axis is 23°. The medial rectus and the inner side of the orbit are nearly parallel, so the angle with the visual axis is close to 0°. The lateral rectus and the outer side of the orbit are nearly parallel, so the angle with the visual axis is close to 45°.

[0151] Based on the fact that the contact point of the extraocular muscles is in front of or behind the equator of the eyeball, and at different angles relative to the eye axis in the first eye position, each extraocular muscle will have its primary, secondary, and tertiary effects on the rotation of the eye axis when it contracts. When the eye axis is rotated to a point that is not in the first eye position, the secondary or tertiary effect of a certain extraocular muscle can override or be different from its own primary effect.

[0152] According to Sherrington's law, when an agonist muscle is activated, the nervous system will simultaneously inhibit the opposite antagonist muscle. Taking advantage of this feature, the training we designed is to intentionally move the eye axis to the favorable "field grid" quadrant visual field range to specifically train and strengthen specific extraocular muscles that are weakened in pseudomyopia and true myopia, while weakening specific extraocular muscles that are strengthened in pseudomyopia and true myopia.

[0153] When looking at the visual target in the nasal quadrant visual field for a long time, in order to obtain and maintain binocular single vision, according to Hering's law, both eyes need to use the medial rectus muscle to converge for a long time (the primary function of the medial rectus muscle is adduction) to maintain the eye axis deviation to the nasal quadrant visual field, which is easy to cause the occurrence and development of myopia. What's worse is that when the eyes look at the visual target in the inferior nasal quadrant visual field when reading, the medial rectus muscle and the superior oblique muscle need to be used to move the visual axis to the inferior side of the nose, which is more likely to cause the occurrence and development of myopia (when the medial rectus muscle adducts the eye axis, the secondary function of the superior oblique muscle exceeds the primary function and turns the eye axis downward to the inferior side of the nose). When the eyes look at the visual target in the superior nasal quadrant visual field, the medial rectus muscle and the inferior oblique muscle need to be used to move the visual axis to the superior side of the nose, which causes the occurrence and development of myopia (when the medial rectus muscle adducts the eye axis, the secondary function of the inferior oblique muscle exceeds the primary function and turns the eye axis upward to the superior side of the nose). According to Sherrington's law, the lateral rectus, superior rectus, and inferior rectus muscles will all be chronically inhibited and weakened.

[0154] In order to resist the nasal quadrant visual field that is prone to the occurrence and development of myopia, especially the inferior nasal quadrant visual field, the direction of movement of the sight mark during training is to move the trainee's eye axis to the favorable temporal side, superior temporal side or inferior temporal side (i.e. the first and fourth quadrants of the right eye, the second and third quadrants of the left eye). During training, when both eyes look at the sight mark located in the temporal quadrant visual field at the same time, in order to achieve and maintain binocular single vision, according to Hering's law, the brain's visual center will guide the corresponding extraocular muscle nerve nucleus of the brainstem to make both eyes use the lateral rectus muscle for abduction at the same time (the primary function of the lateral rectus muscle is abduction) to maintain the eye axis deviated to the temporal side. If the sight mark moves to the superior temporal quadrant visual field, the lateral rectus muscle and superior rectus muscle need to be used (when the lateral rectus muscle abducts the eye axis, the primary function of the superior rectus muscle is strengthened, and the eye axis is turned upward to the superior temporal side). If the sight mark moves to the inferotemporal quadrant, the lateral rectus and inferior rectus muscles need to be used (when the lateral rectus abducts the eye axis, the primary function of the inferior rectus is strengthened, and the eye axis is turned downward to the inferotemporal side). According to Sherrington's law, this will strengthen the lateral rectus, superior rectus, and inferior rectus muscles, while inhibiting and weakening the tension of the medial rectus, superior oblique, and inferior oblique muscles.

[0155] Specifically, the movement rule of the central training sight mark 300 of the present invention is as follows:

[0156] The trainee's eyes are at the first eye position, that is, the center of the grid, corresponding to Figure 2 The training starts at the A1 and A2 positions in the image. The direction and trajectory of the central training sight mark 300 are:

[0157] First, along the horizontal line outward to the C1 and C2 positions, train the lateral rectus muscle to abduct the eye axis from 0° (toward 90° on the temporal side).

[0158] Second, follow the oblique line upward to the temporal side (23° to the superior temporal side), that is, to the B1 and B2 positions, and simultaneously train the superior rectus muscle to rotate the eye axis upward.

[0159] Third, follow the oblique line downward to the temporal side to the D1 and D2 positions, and specifically train the lateral rectus muscle to abduct the eye axis (23° to the inferior temporal side).

[0160] Not limited to the above movement trajectory, the order of the movement direction of the central training sight mark 300 can also be arbitrarily combined, for example: first outward, then upward (or downward), then outward again...etc.

[0161] The first eye position refers to when both eyes are looking at a target at a long distance (more than 6m) in the true horizontal plane, and the two eyes are looking forward and parallel. The eye position at this time is the first eye position. Regarding the distance between the two central training sight marks 300, the distance between the two is slightly larger than the interpupillary distance of the first eye position of the trainee, usually at least interpupillary distance + 2mm. The starting positions of the two central training sight marks correspond to Figure 2 A1 and A2 in the figure. For the specific extraocular muscles to be trained, the central training sight mark 300 is moved along the angle direction of the eye axis required for training. The end point is when the highest value of reverse fusion is reached, that is, when both eyes observe that the central training sight mark 300 on the display screen 200 cannot be reversely fused in the brain and double images begin to appear, it is the end position.

[0162] The above training is based on the application of Hering's law and Sherrington's law. The purpose is to use the static or dynamic training sight marks in the upper and lower temporal visual fields of both eyes. Through the requirements of Hering's law for binocular single vision, the activation of the reverse fusion mechanism is guided in a targeted manner to achieve and maintain the purpose of training.

[0163] At the same time, during the above training process, the activation of the near reflex pathway center is also inhibited, and specific binocular abduction movements are controlled to train and strengthen the extraocular muscles of the abduction muscles. Specific binocular abduction movement training is controlled, and Sherrington's law is applied to weaken the extraocular muscles of the cohesion muscles.

[0164] Since the near reflex pathway of people with pseudomyopia and true myopia is easily activated, the more training is done, the easier it is to inhibit the near reflex pathway center and reduce the tendency to be easily activated. The central training sight mark 300 is statically located or dynamically presented along the main movement direction and range of a specific extraocular muscle, so that the abductor extraocular muscles can be most effectively activated and strengthened while weakening the cohesive extraocular muscles.

[0165] Figure 3a Given Figure 2 Schematic diagram of the left and right visual fields of the trainee and their reverse fusion in the visual center of the brain when the central training sight mark 300 moves in the horizontal directions A1-C1 and A2-C2.

[0166] The left and middle columns respectively show the images of the left and right visual fields when the central training sight mark 300 moves from A1, A2 to C1, C2 and then returns to A1, A2. The right column shows the image of the binocular single vision state formed after the two images are reversely fused through the visual center of the brain.

[0167] When the binocular single vision state disappears and binocular ghosting begins to appear, the central training sight mark 300 stops moving toward the temporal side and starts moving in the opposite direction back to the starting position.

[0168] Figure 3b Given Figure 2 Schematic diagram of the left and right visual fields of the trainee and their reverse fusion in the visual center of the brain when the central training sight mark 300 moves obliquely upward in the directions A1-B1 and A2-B2.

[0169] The left and middle columns respectively show the images of the left and right visual fields when the central training sight mark 300 moves from A1, A2 to B1, B2 and then returns to A1, A2. The right column shows the image of the binocular single vision state formed after the two images are reversely fused through the visual center of the brain.

[0170] When the binocular single vision state disappears and binocular overlap begins to appear, the central training sight mark 300 stops moving upward to the temporal side and starts moving in the opposite direction back to the starting position.

[0171] Figure 3c Given Figure 2 Schematic diagram of the left and right visual fields of the trainee and their reverse fusion in the visual center of the brain when the central training sight mark 300 moves obliquely downward in the directions A1-D1 and A2-D2.

[0172] The left and middle columns respectively show the images of the left and right visual fields when the central training sight mark 300 moves from A1, A2 to D1, D2 and then returns to A1, A2. The right column shows the image of the binocular single vision state formed after the two images are reversely fused through the visual center of the brain.

[0173] When the binocular single vision state disappears and binocular overlap begins to appear, the central training sight mark 300 stops moving downward to the temporal side and starts moving in the opposite direction back to the starting position.

[0174] From the above Figure 3a to 3c As can be seen in the right column, the trainee's left and right eyes see the central training sight mark. When the sight mark moves, the two eyes fuse to combine the sight marks of the two graphics into a complete and clear sight mark. When the sight mark continues to move, the complete and clear sight mark will have overlapping images, and the sight mark should stop moving at this time.

[0175] It should be noted that, compared with the 2D planar sight mark that can only be obtained by the visual processing area of ​​the brain during monocular observation, the formation of the 3D stereoscopic sight mark obtained during binocular observation is an improvement in the visual processing function of the brain. Therefore, the central training sight mark 300 of the present invention can also use a 3D stereoscopic sight mark to replace the above 2D training sight mark.

[0176] In fact, the visual processing area of ​​the brain will be more interested in and pay attention to the stereoscopic sight mark, and will continue to function to maintain its continued existence, so the visual processing area of ​​the brain will feedback guide the specific extraocular muscle nerve nuclei in the brainstem to maintain or move the visual axis of the eyes to maintain the continuation of the stereoscopic sight mark of interest. At this time, the two eyes can be still at the same time, converge (this eye convergence movement is avoided during training, it is the two eyeballs moving inward in opposite directions at the same time), abduct (this eye abduction movement is encouraged during training, it is also the two eyeballs moving outward in opposite directions at the same time), up, down, left, right or diagonally at the same time in the same direction (movement to the left, right or diagonally at the same time in the same direction is avoided during training). The continuous maintenance of the vision of the stereoscopic sight mark when the eyeballs move will feedback guide the two eyes to move along the original movement trajectory until it exceeds the limit of the fusion mechanism of the visual processing area of ​​the brain. At this time, the sight mark fused into three dimensions will be decomposed into two 2D planar sight marks and produce double vision. By utilizing the visual advantages of 3D stereoscopic sight marks over 2D flat sight marks, the visual processing area of ​​the brain can be trained to repeatedly inhibit the center of the near reflex pathway, relax the ciliary muscles to restore the lens accommodation to its state before the increase, and at the same time encourage both eyes to perform abduction movements to strengthen the abduction extraocular muscles that are relatively weakened by myopia, and weaken the cohesion extraocular muscles that are relatively strengthened by myopia.

[0177] For example: complete or incomplete sight patterns in the left and right eyes

[0178] It can be a complete optotype pattern for the left and right eyes, and the purpose is to require the left and right eyes to put the two complete optotype patterns together to form a complete (3D) optotype and background. It can also be an incomplete optotype pattern for the left and right eyes, for example, the lion pattern is intermittent and incomplete. The purpose is to require the left and right eyes to put the two incomplete optotype patterns together to form a specific complete (3D) optotype and background.

[0179] In order to ensure the above training effect, the moving speed of the central training sight mark 300 adopted by the present invention is in the range of 0.1° to 3° / second.

[0180] In addition to the above-mentioned circle-shaped sight marks with complementary contrast, the following types can also be used:

[0181] Pattern sight signs include: animals, plants, landmarks, mountains and rivers, cars, ships, airplanes, daily necessities, restaurants, hotel lobbies and concert halls. These sight signs can be real photographic images, paintings or cartoon images.

[0182] Text sight signs, including: Chinese characters, Tang and Song poems, Three Character Classic, etc. Foreign languages: such as English, French, German, Latin, etc.

[0183] Pattern + text combination visual signs, for example: a lion pattern and the Chinese character or foreign word "lion" appear at the same time or one after the other.

[0184] Switching between various combinations in the scene, for example: patterns and patterns (lion and then tiger), patterns and text (lion pattern and Chinese or foreign lion appear at the same time or one after the other), text and text (Chinese first and then foreign language, etc.).

[0185] When viewed from a distance of 45 cm using a tablet computer, the size of the sight mark is approximately 15 mm x 15 mm (based on the relative training distance, the size can be appropriately changed to cater to the visual acuity level and training needs of the trainee).

[0186] It should be noted that the training sight mark 300 used in the present invention is on a 2D plane and satisfies the following ratio:length:width≤5:1, or width:length≤5:1.

[0187] This regulation is intended to eliminate the discomfort caused by the difficulty of the brain trying to fuse the visual signs seen by the left and right eyes, such as dizziness and headache. Therefore, when the trainee fuses the left and right images of the same size into a single image, the visual sign on one side can be enlarged or reduced, but the size deviation must be less than 10%, so as to stimulate the brain to achieve the purpose of fusion and training while keeping the relative distance and angle between the left and right eyes unchanged.

[0188] Regarding the color of the training sight mark, the changes in the background color and the application, for example:

[0189] a. The training sight mark can be a tiger with no color but only the outline, and then the outline is automatically filled with more colors gradually to obtain a complete tiger.

[0190] b. The colors on both sides can be the same or different to achieve a superposition or mixing effect, such as alternating colors, such as red, green, blue, yellow, etc. In addition, the visual center will superimpose similar sight marks of different colors from two monocular eyes to obtain a sight mark of a different color after mixing (a blue sight mark superimposed on a green sight mark of another monocular eye will obtain a light blue sight mark), forming a complete (3D) specific color sight mark and background.

[0191] c. The color can change in depth, for example: light green deepens to emerald green and then to dark green, or from dark to light.

[0192] d. The background color is gray to reduce unnecessary bright light stimulation, so as not to interfere with the trainees' concentration on the central and peripheral training visual targets.

[0193] Regarding the change of the brightness of the training sight mark, the brightness of the sight mark can be changed rhythmically, from relatively dark to relatively bright, or relatively bright to relatively dark, back and forth, to avoid the pupil reaction being affected by excessive brightness and unnecessary increase in accommodation.

[0194] In addition, train the static and dynamic modes of visual indicators (static, dynamic, combination of static and dynamic, integration of mosaics, and short film formats).

[0195] Training is performed by selecting a fixed or random program of static and dynamic patterns of training sight marks.

[0196] During static training, the sight mark does not move, and the sight marks seen by both eyes do not move.

[0197] During dynamic training, the sight mark moves in a step-by-step or jump-like pattern. For example, the training sight mark for one eye is a bird, and the training sight mark for the other eye is a birdcage (the size is just right to hold the bird, and the bird must be visually maintained in the cage during training).

[0198] a. The visual mark of each monocular eye is moving.

[0199] b. The sight mark of one monocular eye is fixed, while the sight mark of the other monocular eye is moving.

[0200] c. The visual mark of each eye moves alternately.

[0201] Mixed static and dynamic training:

[0202] Example 1: When making a mosaic image, the training sight marks are very incomplete at the beginning. It is necessary to piece together the image parts drawn by different curves bit by bit to finally get a complete mosaic image.

[0203] Example 2: Add shadows around the outline of the training sight mark, or add additional images (such as adding a bird on the back of a cow, or a tree next to the cow).

[0204] Example 3: Use cartoon short stories to present sight signs and conduct training.

[0205] In addition, in terms of the display time and movement speed (duration) of the training sight mark, the display time and movement speed of the training sight mark can be controlled to be faster or slower to produce a more efficient visual impact.

[0206] Considering that the average blink time is 0.3 to 0.4 seconds, the visual mark should be displayed for no less than 0.5 seconds. In addition, considering the "Trexler fading effect", after focusing on a visual mark for 20 seconds or more, the visual stimulus will fade and disappear, so the display time of the visual mark during training should be controlled to no more than about 10 seconds.

[0207] Start with a slow movement speed, using the brain's sight mark to slowly track the movement mechanism, so that the extraocular muscles that resist the near reflex pathway move along the primary movement direction, and determine the minimum distance of the monocular sight mark relative to the midline from the pupil distance of both eyes, which is used as the minimum value of reverse fusion, that is, the starting point, and proceed along the angle direction of the trained extraocular muscle connected to the eyeball to reach the highest value of reverse fusion, that is, the end point. When repeating the training, slowly increase the tracking speed to the maximum value.

[0208] After getting used to the faster tracking movement, the sight mark changes to a jumping form. At this time, the brain uses the sight mark to quickly scan the movement, and the pupil distance of both eyes is used to determine the minimum distance of the monocular sight mark relative to the midline. This is used as the minimum value of reverse fusion, that is, the starting point, and the angle direction of the trained extraocular muscle connected to the eyeball is followed to reach the highest value of reverse fusion, that is, the end point. When repeating the training, slowly increase the scanning speed to the maximum value.

[0209] For the relationship between a series of training sight signs that appear one after another, for example, the text of the Tang poetry sight sign is composed of the images seen by the left and right eyes. Through the movement, repetition and combination of each sight sign, a complete, coherent and meaningful text is formed. The image sight signs of various musical instruments and objects can also be combined in different forms to form a complete image. There can also be training in mathematical operation patterns, introduction to astronomy or historical knowledge, etc.

[0210] In addition, the training sight mark of the present invention can be combined with audio, and the audio content and the training sight mark can be organically coordinated, including language explanation, music or both, which can tell a story and can also be accompanied by various types of background music.

[0211] For example: the combination of music score and music sound. The sound can be the music itself or the background introduction of the music, including the composer, the background of the composition and the story related to the music. Purpose: To resonate with the sight mark, and add background commentary music to achieve educational effect and maintain concentration on training.

[0212] The combination of the above-mentioned training aims to continuously and effectively stimulate the visual processing center of the brain through efficient sight mark presentation methods, avoid the "Trexler vanishing effect" caused by a single, non-moving sight mark, thereby avoiding visual fatigue, prolonging the stimulation time, maintaining the focus of training, increasing attractiveness, and greatly enhancing the stimulation effect per unit time. In this way, the inhibition of the near reflex pathway center can be increased, the ciliary muscle can be relaxed to restore the lens accommodation to the state before the increase, the abduction extraocular muscles can be strengthened and the cohesion extraocular muscles can be weakened, thereby achieving the training goal of short time and high efficiency.

[0213] The present invention makes the training sight marks have connections or story elements, which can form associative elements to form logical plots or scenes. Through the interactive training media mode of vivid, interesting and informative sight marks (with related audio or background music), it can simultaneously achieve the improvement of knowledge and educational effects (teaching and learning benefit each other), and avoid the lack of concentration and low efficiency of training results caused by boring training process.

[0214] Use attractive sight marks. The sight marks will appear in the following ways: 3D stereoscopic sight marks, appearance and disappearance of sight marks, color changes, enlargement and reduction, slight additions or subtractions in appearance, alternating thickness and reality of contour lines, adding mosaic patterns, moving, jumping, stillness and adding features, contrast (such as synonyms, antonyms, etc.), etc. This will avoid the emergence of the "Trexler vanishing effect" and maintain the interest of training, so as to achieve continuous stimulation of the brain, maintain reverse fusion well for a longer time and achieve the training goals efficiently.

[0215] It should be noted that the important functions of peripheral vision are: recognition of common structures and forms, identification of similar forms and movements, and formation of a sense of visual background. The perception of central vision plus the contribution of peripheral vision constitute the panoramic and detailed vision that the eyes see in daily life.

[0216] Due to the spherical shape of the eye and the relationship between the size of the pupil in daily life and the relative position of the lens and the peripheral retina, the peripheral retina that clinically contributes significantly to overall vision refers to the range (approximately 25° to 60°) before and after the equator (approximately 43°). Since peripheral hyperopic defocus can also cause and aggravate the formation and progression of myopia, weakening or offsetting the peripheral hyperopic defocus can help inhibit the formation of pseudomyopia and true myopia.

[0217] therefore, Figures 4a to 4g An embodiment of peripheral vision training for unilateral visual field based on central training sight mark is given.

[0218] In this embodiment, the spacing of the central training sight mark 300 is the first eye position plus 2 to 30 mm. In the binocular single vision state, the peripheral training sight marks A and B move at the position of 25° to 60° on the temporal side of the visual field with reference to the central training sight mark.

[0219] in, Figure 4a The figure shows the situation where the peripheral training sight marks A and B are fixed;

[0220] Figure 4b~4d The figure shows that the peripheral training sight mark B is fixed, the peripheral training sight mark A moves toward B, and when A and B overlap, A stops moving;

[0221] Figure 4e~4gThe figure shows that the peripheral training sight mark A moves in the opposite direction away from the training sight mark B until A and B overlap, and then the peripheral training sight mark A stops moving.

[0222] The specially designed peripheral training sight marks A and B mentioned above are required to meet the following requirements:

[0223] (1) Background color of peripheral training sight mark: grayish.

[0224] (2) Color of peripheral training sight mark: Matte black graphics, such as a cartoon picture of a horse

[0225] (3) The location of the peripheral training sight mark: 25° to 60° on the temporal side of the visual field.

[0226] (4) The size of the peripheral training sight mark is 16 times the size of the central training sight mark.

[0227] (5) Static and dynamic movement modes of peripheral training sight marks: When the central training sight mark is set at the position of the first eye position pupil distance plus 2 to 30 mm (not limited to 2 to 30 mm), and binocular single vision is obtained.

[0228] The present invention can be implemented through a complete set of application software. This software can be installed on a computer, a mobile phone or a tablet computer. The trainee can freely select the required training content by directly operating on these interactive terminals, and train by watching the training sight marks on the computer screen, the TV screen or the projection screen. During the training process, the sight marks and background music can be changed according to actual needs.

[0229] The application is available in two versions: online APP and offline APP.

[0230] Through this whole set of special training methods, the following goals can be achieved efficiently:

[0231] Since each eye can only see the visual mark that appears only on the temporal side, and in order to achieve the requirements of binocular single vision and stereoscopic vision, the brain's visual center will apply visual reverse fusion, Hering's law, and Sherrington's law to command the brainstem to achieve the following effects.

[0232] 1. Control and inhibit the proximal reflex pathway center of the midbrain, making it less likely to activate.

[0233] 2. Relax the ciliary muscles, prevent spasms, and try to keep them relaxed.

[0234] 3. Restore the curvature and front-back diameter of the lens surface to a state without additional adjustment, thereby eliminating unnecessary adjustment.

[0235] 4. Instruct the brainstem-related extraocular muscle nerve nuclei to stimulate the abduction extraocular muscles of both eyes and the temporal side and inhibit the cohesion extraocular muscles of the nasal side in accordance with Hering's law so that both eyes can maintain binocular single vision during the abduction movement. In this way, the overdeveloped and overtonic cohesion extraocular muscles can be continuously inhibited, while the weakened abduction extraocular muscles can be strengthened and the decreased muscle tension can be increased.

[0236] 5. Improve poor vision, offset pseudomyopia, slow down or stop the deepening of true myopia and excessive extension of the eye axis.

[0237] 6. Greatly reduce the adverse changes in the eye structure caused by the increase in accommodation and aggravation of myopia, and reduce the complications of the eyes, especially the retina, in future life, such as retinal holes, retinal detachment, retinal hemorrhage, vitreous hemorrhage, vascular proliferation caused by retinal cracks, glaucoma, etc., and the risk of adverse consequences and risks.
