Description

[Technical field]

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

[0002] Myopia is defined as a condition in which the ciliary muscles inside the eye, which are responsible for adjusting the focus, are at their physiologically most relaxed level and distant scenes are focused in front of the central retina. It is well known that this condition can cause poor vision, such as blurred vision and reduced vision.

[0003] When a person looks at a near target, the central near reflex pathway in the midbrain is activated, resulting in changes in three areas: (1) Reflex constriction of the pupil.

[0004] (2) The medial rectus muscles of both eyes contract to keep the visual axes of both eyes aligned on the same target, thereby avoiding diplopia (Hering's law, maintaining binocular monovision).

[0005] (3) Due to the contraction of the ciliary muscles, the curvature of the lens surface becomes more pronounced, the anterior-posterior diameter increases, accommodation is increased, and the entire scene is kept in focus on the central retina, resulting in a clear visual image. When the eye is shifted to view a distant target (6 meters or more away), the central part of the midbrain near reflex pathway is inhibited, and the pupils, medial rectus muscles, ciliary muscles, lens surface curvature, and anterior-posterior diameter of both eyes relax and return to normal, returning to the physiologically relaxed level that is normally observed when viewing distant objects.

[0006] Acquired myopia is generally caused by excessive reading or working at close distances or distances that are too close. When reading or working at close distances for a long time, the target and image are displayed at a relatively close distance, but the center of the near reflex pathway requires long-term activation to increase and maintain binocular accommodation, in which case the ciliary muscle inside the eye and the internal rotator muscle outside the eye need to maintain a contracted state for a long time. Over time, when the center of the near reflex pathway needs to be inhibited to see far away, the eyes no longer converge, and the ciliary muscle may not fully return from the contracted state to the relaxed state because the pupils no longer contract, so that the increased portion of accommodation is maintained when looking at a near object (accommodative spasm), and at this time, the eye is looking at a distant target, but the already increased portion of accommodation is maintained, so the target or image is not focused on the retina, causing vision problems such as blurred vision and reduced vision.

[0007] Accommodative spasm caused by continuous contraction of the ciliary muscle causes a condition known clinically as pseudomyopia, and if this condition continues, the eye axis will grow excessively beyond its normal rate, resulting in true myopia. If this accommodative spasm is not alleviated, pseudomyopia will continue and true myopia will continue to worsen, which is the phenomenon often seen in clinical practice, where students have a high rate of myopia and their myopia increases by 100 to 200 degrees each year.

[0008] Looking at a nearby object for a long time means that the visual axis of both eyes is inward for a long time, and in this position, the medial rectus muscle needs to be activated for a long time, and according to Sherrington's law, the lateral rectus muscle is also inhibited at the same time, and over time, the medial rectus muscle becomes overly strong (more and more developed, with stronger muscle tone) and is easily activated, while the lateral rectus muscle becomes overly weak (more and more weak, with less muscle tone), causing a decrease in performance. In this way, the muscle tone of the two resisting groups of extraocular muscles becomes unbalanced, and there is a tendency for more inward movement, and a vicious cycle promotes the occurrence and progression of pseudomyopia and true myopia.

[0009] The methods of myopia treatment and correction currently used in clinical and commercial practice include the following categories: 1. Measures to offset the refractive error of physical or invasive myopia include the following:

[0010] 1. Wear myopic lenses (non-invasive) or contact lenses (invasive).

[0011] Lenses worn in cases of myopia to correct refractive errors are concave lenses that shift the central and peripheral focal points of the central and peripheral images after refraction by the cornea and crystalline lens backwards in order to focus on the central distant image, but at the same time shift the distant peripheral image further backwards, exacerbating the hyperopic blurring phenomenon around the retina.

[0012] What's more, if a myopic person wears a concave lens that corrects myopic refractive error and continues to read or work at close range, the central and peripheral visual images will be closer to the eye, so the focus of the central and peripheral visual images will move further back, causing hyperopic refractive error. At this time, the out-of-focus central and peripheral visual images will stimulate the visual center of the cerebrum, and in order to obtain a relatively clear image, the latter will activate the center of the near reflex pathway in the midbrain to contract the ciliary muscle (long-term contraction may cause spasms), expand the curvature and anterior-posterior diameter of the lens surface (continuous expansion when the ciliary muscle spasms), and cause an increase in accommodation (continuous increase during ciliary muscle spasms) to focus the visual image, and to achieve the focusing of the peripheral visual image, a stronger accommodation is required, so generally, only the focusing of the central visual image can be achieved, but in this case, the focus of the central visual image will move forward of the central retina, causing a new myopic refractive error. Therefore, correcting myopia by wearing concave lenses for myopic refractive errors can easily cause the development and progression of pseudomyopia or true myopia, which can lead to a rapid increase in the degree of myopia, which can easily increase by 100 or 200 degrees in a year.

[0013] 2.OK lenses (invasive), the cornea is easily damaged, infected and scarred causing permanent vision loss, keratoconus can also sometimes occur.

[0014] 3. Use of atropine mydriasis and cycloplegics (invasive).

[0015] The disadvantages of this type of pupil dilation are:

[0016] (1) As the pupil dilates, a large amount of peripheral vision that is normally blocked by the iris enters the eyeball, causing light pollution to the retina and interference with visual images.

[0017] (2) A large amount of light coming from the visual target image passes through and is refracted in the off-center area of ​​the lens, and because there is a difference in diopters between the central area of ​​the lens and the off-center area, this causes astigmatism and the blurring of the visual target and the visual image.

[0018] (3) Because atropine has a very long half-life, the pupils often remain dilated for two to three weeks after administration, causing many problems such as photophobia.

[0019] In addition, atropine drugs are toxic and can cause side effects such as increased heart rate, fever, dry eyes and mouth, and long-term use can increase the risk of harmful ultraviolet rays entering the eyeball, which can lead to retinal degeneration and macular degeneration. Therefore, although the concentrations used have been significantly reduced over the past few years, the toxicity still exists and there is no significant therapeutic effect. The toxicity of the latest ultra-low concentration atropine 0.01% is still unclear, but the therapeutic effect is not ideal.

[0020] 4. Laser corrective surgery (invasive, involving removal of corneal tissue) is not suitable for the underdeveloped eyes of those under the age of 18.

[0021] Surgery often causes glare and dry cornea, and can lead to infection. Over time, myopia can recur after surgery, and there is an increased risk of retinal rupture and detachment.

[0022] 5. Massage, eye exercises, etc. 6. Acupuncture (invasive) 7. Steam compress (invasive) 8. Improving eyesight with herbal medicine (invasive) Items 5 to 8 of the above methods have been proven clinically ineffective and lack a scientific rationale or explanation.

[0023] Second, in addition to the above-mentioned physical or intrusive means for compensating for myopic refractive error, existing methods of vision training for compensating for myopic refractive error include the following:

[0024] 1. A common method is to alternate between looking at a target in front of you and a thumb or fingertip in front of you. Another common method is to look at a similar target such as a thumb, pen, or ruler moving back and forth. Some training centers use a near-point training machine for this, where the target moves quickly forward and away, then quickly backward and closer (this machine makes a noticeable noise that affects the trainer).

[0025] What they have in common is that the target moves back and forth a certain distance, and moving the target far away is expected to fully relax the accommodation of the eye by utilizing the distance that the target moves away from the eye.However, in reality, the target in the distance is still on the central line, so the eye needs to use the medial rectus muscle to maintain single vision, and cannot fully relax accommodation, and if the target quickly returns to the front of the eye, this is the same situation as inducing the increase of the accommodation effect when reading a book, so these far-point and near-point training methods not only cannot effectively relax accommodation, but also train to increase accommodation when both eyes look at a nearby target, which may cause accommodation spasm.

[0026] 2. Eye movement training carried out in hospitals, ophthalmology clinics, vision training centers, etc. involves moving both eyes 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 inward. When both eyes look to the lower left, the right eye is inward and the left eye is abducted downward. Inward-turned eyes, especially downward-turned eyes, may cause increased accommodation through activation of the center of the near reflex pathway, and at the same time strengthen the medial rectus and superior oblique muscles, which increase myopia. Therefore, this type of training is disadvantageous to the weakening of the medial rectus and superior oblique muscles, which cause increased accommodation and worsen myopia, by at least one downward-turned monocular.

[0027] 3. In other target training, the target is moved in different directions in front of the visual field, in a circular motion (0, ∞, 8, etc.), and the right eye moves inward in both cases. This type of eye movement is a non-purposeful method, and when both eyes are turned inward to look at the target, the ciliary muscles of each eye need to contract. When one eye is abducted and the other eye is turned inward, this can cause the ciliary muscle of the turned in eye to contract. In both of these cases, whether binocular or monocular, the target causes an increase in accommodation.

[0028] All three of the above are bad and incorrect training methods that, far from reducing myopia, maintain or increase the contraction of the ciliary muscle, maintain accommodation and even cause spasms, which in turn maintain or increase pseudomyopia or true myopia, and are therefore undesirable for achieving the goal of delaying or reducing myopia or improving eyesight.

The previous and subsequent operations are not necessarily performed in exact order. Conversely, steps can be processed in reverse order or simultaneously. At the same time, other operations can be added to these processes, or operations of a particular step or steps can be removed from these processes.

[0053] The present invention uses a method of training both eyes separately and uses a training display screen similar to the shape of a rice field during training. The technical solutions for using such training are as follows.

[0054] 1. Use a specially designed partition to divide the common visual field and visual acuity range of both eyes into the individual visual fields and visual acuity ranges of each monocular eye, and each monocular eye cannot see the visual targets and visual fields of the other monocular eye.

[0055] 2. Divide the monocular visual field into the form of a "rice field", and the visual field ranges beneficial for training are selected in the upper quadrant on the temporal side and the lower quadrant on the temporal side.

[0056] Briefly explained, if the present invention defines the entire visual field in front of the monocular eye and the range of the rotational visual axis of the eyeball in the shape of a "rice field", the relative position of the visual target in the "rice field" visual field determines the relative position of the visual axis in the "rice field" range after the eyeball rotates. In normal situations, when the eyes are in the primary eye position, the visual axis is at the position of the center point of the "rice field" shape. According to Hering's law, the brain moves the visual axis directions of both eyes so as to overlap on the visual target. When the visual target is at a distance of more than 6 meters, the visual target in space is located directly in front of the eyeball visual axis, so there is no need for both eyes to converge or abduct. When the visual target is at a short distance of less than 6 meters, both eyes need to converge so that the visual axis directions of both eyes overlap on the visual target. In this case, the brain activates the center of the near vision reflex pathway in the midbrain to converge both eyes and align the visual axis with the visual target. At the same time, the ciliary muscle contracts to change the curvature and anteroposterior diameter of the lens to focus on the near visual target relatively close to this eyeball in order to increase accommodation, and the pupil contracts to reduce the influence of the peripheral visual field.

[0057] In the following cases, at specific positions within the "rice field" range, the central training visual target may cause visual impairment or myopia: Here, take the common example of a child reading with his head down, his eyes move downward and inward so that the visual axis of each eye is completely aligned on the target to be read. The target position is on the nasal and lower side of the "T" range, and is moved to the lower left grid of the "T" for the right eye, and to the lower right grid of the "T" for the left eye. Since the visual axis of each eye needs to face the nasal and lower side, the visual axis of each eye needs to rotate inward and downward to meet the needs of target observation and reading. At this time, the medial rectus muscle, inferior rectus muscle, and superior oblique muscle contract, and the lateral rectus muscle, superior rectus muscle, and inferior oblique muscle relax. The effect of the near reflex pathway contracts the ciliary muscles of both eyes of the child reading a book with his head down, increasing accommodation, and when he looks into the distance again, the effect of the near reflex pathway is no longer needed, and the ciliary muscles and accommodation should completely return from the tense state to the original relaxed state. However, when repeated close-up viewing and reading are repeated frequently over a long period of time, the ciliary muscle and accommodation often do not fully return to their original relaxed state, resulting in the common development of pseudomyopia and true myopia.

[0058] From the above, when the visual target is on the nasal side of the "T" shape, in order to achieve binocular single vision (Herling's law), the visual axis of each eye must face the nasal side, and in this inward rotation movement, the contraction of the medial rectus muscle and the relaxation of the lateral rectus muscle of both eyes must be performed synchronously to achieve the effect of both eyes simultaneously inwardly rotating the axis of the eye. To achieve the effect of inward rotation, the brain needs to activate the center of the near reflex pathway and at the same time contract the ciliary muscle to increase accommodation. Therefore, placing the visual target in the nasal position of a "T" shape is not good, and even worse for people with pseudomyopia or true myopia. This causes the activation of the near reflex pathway, causing inward rotation, contraction of the ciliary muscle and increased accommodation, which are exactly what we want to avoid.

[0059] Therefore, the axis of the eye must avoid entering the nasal space, especially the space below the nose, and the temporal space is the most preferable because the medial rectus, superior oblique, and inferior oblique muscles do not need to be used when the axis of the eye is moved to this area. Therefore, the visual field range useful for training is selected to be the upper and lower quadrants of the temporal side of the "T-shaped" shape.

[0060] Therefore, the square range description is an appropriate training display.

[0061] According to the above explanation useful for training, the square-shaped training target can achieve a beneficial training effect when it appears in a specific position in the visual field corresponding to the upper and lower temporal quadrants of the square-shaped target.

[0062] 3. Based on this, the present invention trains with a visual target of a specific movement direction (adjusted to the main movement direction and angle of the specially trained extraocular muscles, applying Hering's law and Sherrington's law).

[0063] The training induces both eyes to make simultaneous temporal abductive eye movements through the direction of target movement, while simultaneously suppressing the need for inward movement, so that the brain inhibits central activation of the midbrain near reflex pathway, causing the ciliary muscles in pseudomyopic and true myopic eyes to contract and spasm, increasing accommodation of the lens and giving the eye a chance to return to normal.

[0064] 4. Reverse integration of targeted induction and training (application of Hering's Law and Sherrington's Law) If one simply relies on training with a specific monocular target in the temporal quadrant of the monocular's "T-shaped" visual field, one can adequately train specific extraocular muscles such as the lateral rectus, superior rectus, and inferior rectus of one eye, while simultaneously strengthening the medial rectus, superior scalene, and inferior scalene of the other eye, according to Hering's law. Thus, training relying on a specific monocular target cannot maintain maximum central inhibition of the near reflex pathway, nor can it simultaneously strengthen the lateral rectus and weaken the medial rectus in the most efficient manner.

[0065] Therefore, during training, similar visual targets are provided to the two monoculars simultaneously, and the distance between the two visual targets is equal to or greater than the interpupillary distance in the first eye position. The visual processing center of the brain is used to recognize each visual target collected by the two monoculars, and then fuse them together to obtain the effect of binocular single vision, which can simultaneously increase the inhibition of central activation of the near reflex pathway, relax the ciliary muscle from a contracted or spasmodic state, and return the anterior-posterior diameter of the lens from an expanded state to normal, while simultaneously strengthening the lateral rectus muscle and weakening the medial rectus muscle.

[0066] 5. Formation and maintenance of specific 3D stereoscopic targets (application of Hering's law and Sherrington's law) The same type of targets provided to each of the two monoculars can also be specially designed to have complementary differences. In this case, the visual processing center of the brain can conveniently recognize the targets collected by the two monoculars and then fuse them to obtain the effect of binocular single vision 3D stereo target. The 3D stereo target and vision feedback greatly strengthen the central inhibition of the near reflex pathway, strengthen the lateral rectus muscle, weaken the medial rectus muscle, eliminate the spasm of the ciliary muscle, and relax accommodation.

[0067] There are three stages in binocular single vision, from the first stage where the brain recognizes that the same target is seen simultaneously by the maculae of both eyes, to the second stage where the brain fuses the same target seen by both eyes and maintains the fusion, to the third stage where the brain fuses the same target seen by both eyes into a stereo target and maintains the stereo fusion. The three training methods related to 3 to 5 above can comprehensively train binocular single vision to reach different levels of trainees.

[0068] All three of these training methods use the reverse fusion mechanism in the visual center of the brain to achieve the goal of binocular single vision. These training methods improve the reverse fusion ability (reverse fusion becomes easier) and range (e.g., reverse fusion range progresses from 0-40mm to 0-50mm). Look at it from 45cm away ) at the same time, so that the purpose of training can be achieved and strengthened.

[0069] In addition, with respect to the training targets, the present invention further specifically provides the following: 1. Exchange of various types of training targets (images, text, numbers, etc.) 2. Special expression change methods and formats of the training targets (size, ratio, color change, dotted outline and solid outline, etc.) 3. Display time of the training target (length of time) 4. Static and dynamic states of the target (dynamic, static, combined dynamic and static, and mosaic integration) Due to the natural need and tendency of binocular monocular vision, the brain statically fuses similar targets in each of the two monoculars (when the target does not move) or dynamically fuses them (when the target moves, the brain's slow tracking mechanism needs to be applied), so that the target can be represented using a static-dynamic mixed method to achieve the stimulation effect.

[0070] The above training targets 1 to 4 setting For, some of the objectives are to avoid the "Troxler effect" to avoid visual fatigue, to maintain the concentration of training, and to extend the stimulation time, thereby achieving the effects of increasing central inhibition of the near reflex pathway, strengthening the extraocular muscles, weakening the extraocular muscles, relieving ciliary muscle spasms, relieving ciliary muscle spasms, and relaxing accommodation.

[0071] Based on this, it is possible to design a series of consecutive training symbols that are further related to each other in meaning, or to link the symbols with audio and have story elements appear between them to form a logical plot or scene with the elements that can be related.

[0072] The content and presentation method of the above training targets can achieve sustained attraction, concentration, interactivity, entertainment, and education. With the most economical time cost, it is possible to obtain the most efficient inhibition of the center of the near reflex pathway, strengthening of the lateral rectus muscle, weakening of the medial rectus muscle, elimination of ciliary muscle spasm, and relaxation of accommodation.

[0073] The configuration of the training device of the present invention will be described below with reference to FIGS.

[0074] The training device includes a binocular field splitter 100 and a display screen 200, the former of which is used to split the binocular field into separate viewing regions for each of the monoculars, and the latter of which is used to provide movable training targets for the monoculars.

[0075] Here, the visual field splitting device includes two partitions 1, each of which is open on one side and connected to the other side to form a certain angle, and the size of each partition is: bottom side length 42 cm (between 40 cm and 45 cm, not limited to this length range), height range 15 cm to 45 cm (not limited to this height range, determined according to the height of the display screen 200). The color of both partitions 1 is matte charcoal black. The training side 6 is configured on the opposite side of the connected side, and one side of the opening constitutes the side 3 close to the display screen, which is used to approach the display screen 200. And the binocular visual field splitting device 100 can be folded to adjust the included angle of the two partitions.

[0076] The preferred embodiment shown in FIG. 2 shows the structure of an adjustment unit 5, which is disposed between the two partition boards on the side 3 close to the display screen, and includes an adjustment knob 51 and an adjustable telescopic bracket 52, where the adjustable telescopic bracket 52 is telescopically connected to the two partition boards and is telescopically adjusted via the adjustment knob 51 disposed thereon, thereby adjusting the included angle between the two partition boards.

[0077] In order to obtain a more comfortable training effect, the joint of the two partition plates 1 of the binocular visual field splitting device 100 is the training side 6, i.e., a curved surface designed to fit the contours of the head and face of the person close to the trainee.

[0078] The open ends of both dividers 1 form the side 3 near the display screen, i.e., near the display screen 200, and cooperate with an adjustment knob 51 for adjusting the size of the opening to make a corresponding adjustment according to the interpupillary distance when the trainee's eyes are in the first eye position, so that the interpupillary distance during training is equal to or greater than the interpupillary distance when the eyes are in the first eye position, and there is also a non-slip bottom edge 2 for placing both dividers 1 stably on a flat desktop, and a removable forehead rest 7 or chin rest 8 for the trainee's comfort.

[0079] The binocular field splitting device 100 is disposed between a display screen 200 and the trainee's eyes, and training is performed below The above two disadvantageous factors can be avoided. By using both partitions, when each monocular looks at the target, it is not attracted or disturbed by the target in the opposite visual field. With the above design of the two partitions, the size of the opening of the two partitions can be adjusted according to the different interpupillary distances of each trainee, thereby avoiding the target appearing in the nasal visual field of each monocular and achieving the training purpose that the target appears only in the temporal visual field favorable to the trainee.

[0080] This will be explained in further detail below. 2 is a schematic diagram showing the combination of the binocular visual field splitting device 100 and the display screen 200 of the present invention. The display screen 200 displays two cross-shaped combinations, and the side 3 of the binocular visual field splitting device 100 close to the display screen approaches the surface of the display screen 200, and the binocular visual field splitting device 100 divides the entire display screen into the display screens 200 on both sides and the central blocking area 4, and the central training target 300 on the display screen 200 moves according to a certain rule, and the trainee on the training side 6 can observe the moving trajectory of the central training target 300 to obtain a training effect.

[0081] When the central training target 300 moves on the display screen 200, the trainee's description of the observation situation is as follows: 1. Special position displayed by the central training target 300 (1)Quadrant visual field range composed of the X-axis and Y-axis: Role of the position of the central training target in the quadrant The coordinate position of the selective central training target 300 and its application. When both eyes look straight ahead at the primary eye position, the interpupillary distance exactly matches the pupillary distance when both eyes are neither converging inward nor abducting outward. In this case, the coordinates of the central training target are exactly at the center point of a "field" - shaped visual quadrant. The Y-axis passing through the center point defines the visual field ranges of the nasal and temporal quadrants. The visual field range of the nasal quadrant is likely to activate the near reflex pathway. The x-axis passing through the center point defines the visual field ranges of the upper and lower quadrants. The visual field range of the lower nasal quadrant is most likely to activate the near reflex pathway. Based on the previously mentioned "the most suitable quadrant visual field ranges for training are the upper and lower temporal quadrants" (the directions of the four diagonal arrows on the display screen 200 in Figure 2) in the advantageous position of the above "field" shape, for the trainee, the first and fourth quadrants of his right eye, and the second and third quadrants of his left eye are the most advantageous quadrant visual field ranges for vision training. Therefore, the central training target we use is only displayed within these ranges. Since it is necessary to maximize the strengthening of the three extraocular muscles, the lateral rectus, superior rectus, and inferior rectus, while avoiding the activation of the near reflex pathway, the other quadrants are not used.

[0082] (2)Adjust the starting point position of the central training target to match the eye position of the trainee.

[0083] Some people have latent strabismus, so there may be horizontal (left - right) or vertical (up - down) deviations in the left and right eyes. The most serious deviation is the vertical deviation, and even a slight deviation may cause visual interference. Therefore, before starting the training, there is an operation function to adjust and correct the target position so that the eye axes of both eyes are in a state and position where the deviation is neutralized, and the left and right eyes are in their original relatively neutral state and position from the beginning. When the pupils of both eyes of the trainee are at the most accurate training starting point with respect to the X-axis and Y-axis, the deviations caused by the trainee's head irregularities or latent strabismus are already eliminated, and the unwanted interference caused by the deviation of both eyes in the horizontal and vertical lines is avoided.

[0084] (3) Distance between the central training target and the trainee The distance between the central training target and the trainee is adjusted according to the type of monitor, but for general PC and tablet PC monitors it is at least 45 cm, and when using a television or large screen projection, it should conform to the normal viewing distance.

[0085] 2. Specific movement direction and trajectory of the central training target (1) The angle and trajectory of the direction of movement of the central training target when it is in primary position relative to the eye (using Hering's law and Sherrington's law to match the primary direction and angle of movement of the particular trained extraocular muscle).

[0086] The contact points of the extraocular muscles and the eyeball have a relatively fixed positional relationship, and the contact points of the medial rectus, lateral rectus, superior rectus, and inferior rectus muscles with the eyeball are in front of the equator of the eyeball. The contact points of the superior oblique and inferior oblique muscles with the eyeball are all behind the equator of the eyeball. There are also relatively fixed angles between the extraocular muscles and the visual axis. In primary position, the angle between the superior and inferior oblique muscles and the visual axis is 51°, and the angle between the superior and inferior rectus muscles and the visual axis is 23°. Because the medial rectus and the medial orbit are nearly parallel, the angle with the visual axis is close to 0°, and because the lateral rectus and the lateral orbit are nearly parallel, the angle with the visual axis is close to 45°.

[0087] Because the contact points of the extraocular muscles are in front of or behind the equator of the eye, and based on the various angles relative to the axis of the eye when in primary position, each extraocular muscle has a primary, secondary, and tertiary effect on the rotation of the axis of the eye whenever it contracts. When the axis of the eye is rotated so that it is not in primary position, then the secondary or tertiary effect of a particular extraocular muscle can exceed or be different from its own primary effect.

[0088] According to Sherrington's law, when an agonist muscle is activated, the nervous system simultaneously inhibits the opposing antagonist muscle. Taking advantage of this feature, our designed training intentionally shifts the eye axis into the favorable "cross-shaped" quadrant of the visual field to target and train and strengthen specific extraocular muscles that are weakened in pseudomyopia and true myopia, while simultaneously weakening specific extraocular muscles that are strengthened in pseudomyopia and true myopia.

[0089] According to Hering's law, when viewing a target in the nasal quadrant visual field for a long time, in order to obtain and maintain binocular single vision, the eyes must use the medial rectus muscle for a long time to move inward (the main function of the medial rectus muscle is to move inward), so that the eye axis is kept biased to the nasal infranasal quadrant visual field, which is likely to cause the onset and progression of myopia. Furthermore, when reading, when both eyes view a target in the nasal infranasal quadrant visual field, the medial rectus muscle and superior oblique muscle must be used to move the visual axis to the nasal infranasal quadrant visual field, which is likely to cause the onset and progression of myopia (when the medial rectus muscle moves the eye axis inward, the secondary action of the superior oblique muscle exceeds the primary action to move the eye axis downward to the nasal infranasal). When viewing a target in the nasal upper quadrant visual field with both eyes, the medial rectus muscle and inferior oblique muscle must be used to move the visual axis to the nasal upper side, which is likely to cause the onset and progression of myopia (when the medial rectus muscle moves the eyeball inward, the secondary action of the inferior oblique muscle exceeds the primary action to move the eye axis upward to the nasal infranasal). According to Sherrington's law, the lateral rectus, superior rectus, and inferior rectus muscles are inhibited and weakened over time.

[0090] In order to counter the visual field of the nasal quadrant, especially the inferonasal quadrant, which is likely to cause the onset and progression of myopia, the direction of movement of the visual target during training should move the trainee's eye axis to the favorable temporal, superior, or inferior temporal side (i.e., the first and fourth quadrants of the right eye, and the second and third quadrants of the left eye). When both eyes simultaneously view a visual target located in the visual field of the temporal quadrant during training, according to Hering's law, in order to achieve and maintain binocular monovision, the visual center of the cerebrum instructs the corresponding extraocular muscle nerve nucleus in the brainstem to use the lateral rectus muscle to simultaneously abduct both eyes (the main function of the lateral rectus muscle is abduction) to maintain the temporal deviation of the eye axis. When the visual target is moved to the superior temporal quadrant visual field, the lateral rectus muscle and superior rectus muscle must be used (when the lateral rectus muscle abducts the eye axis, the primary action of the superior rectus muscle is strengthened to abduct the eye axis to the superior temporal side). Moving the visual target into the inferotemporal visual field requires the use of the lateral and inferior rectus muscles (as the lateral rectus abducts the eye axis, the primary action of the inferior rectus is strengthened, advancing the eye axis in the inferotemporal direction). According to Sherrington's Law, this achieves the strengthening of the lateral, superior, and inferior rectus muscles while inhibiting and weakening the tone of the medial rectus, superior oblique, and inferior oblique muscles.

[0091] Specifically, the operation rules of the central training target 300 of the present invention are as follows: When the trainee’s eyes are in the first eye position, that is, the central position of the square, corresponding to the positions A1 and A2 in FIG. 2, the training starts, and the direction and trajectory of the movement of the central training target 300 are as follows: First, move outward along the horizontal line to the C1 and C2 positions and perform targeted training on the lateral rectus muscle to abduct the eye axis from 0° (90° toward the temporal side).

[0092] Second, move upward along the oblique line to the temporal side (23° toward the superior temporal side), i.e., to positions B1 and B2, while simultaneously training the superior rectus muscle to rotate the eye axis upward.

[0093] Third, move along the oblique line downward toward the temporal side to positions D1 and D2, and abduct the eye axis. under Targeted training of the rectus muscles (23° temporal direction).

[0094] In addition to the above-mentioned movement trajectories, the movement directions of the central training target 300 can be arbitrarily combined, for example: first outward, then up (or down), then outward, etc.

[0095] The first eye position is when both eyes are gazing at a target at a long distance (6 m or more) on a true horizontal plane, and the gaze lines of both eyes are parallel to the front in the same direction. The distance between the two central training targets 300 is slightly larger than the interpupillary distance of the trainee in the first eye position, and is usually at least the interpupillary distance + 2 mm, and the starting positions of the two central training targets correspond to A1 and A2 in FIG. 2, respectively. For a specific extraocular muscle to be trained, the central training target 300 advances along the angle or direction of the eye axis movement required for training. The end point is when the maximum value of reverse fusion is reached, that is, when it is observed that the central training target 300 cannot be reverse fused in the brain on the display screen 200 with both eyes and multiple shadows appear, this is the end position.

[0096] The above training is based on the application of Hering's law and Sherrington's law, with the aim of using static or dynamic training target presentations in the superior and inferior temporal visual fields of both eyes, achieving and maintaining the training objectives by targeted induction of the activation of the reverse fusion mechanism through the requirements of Hering's law for binocular monovision.

[0097] At the same time, the above training process also inhibits the central activation of the near reflex pathway, controls specific binocular abduction movements to train and strengthen the extraocular muscles of the abducted muscles, controls specific binocular abduction movement training, and applies Sherrington's law to weaken the extraocular muscles of the medial rectus.

[0098] Since the center of the near reflex pathway of a person with pseudomyopia and true myopia is easily activated, the more training, the easier it is to inhibit the center of the near reflex pathway, and the less prone it is to be activated. The central training target 300 is displayed statically or dynamically along the main movement direction and range of a specific extraocular muscle, so that the lateral rectus muscle can be most effectively activated and strengthened, and at the same time, the extraocular muscle that is brought inward can be weakened.

[0099] FIG. 3a shows the left and right eyes of the trainee when the central training target 300 in FIG. 2 moves horizontally from A1 to C1 and from A2 to C2. temporal side A schematic diagram of the visual field and its subsequent back-fusion with the visual centre of the brain is shown.

[0100] The left and center columns show the left and right images of the central training target 300 as it moves from A1 and A2 to C1 and C2, respectively, and then returns to the positions of A1 and A2. temporal side Each column shows an image of the visual field, and the right column shows the binocular single vision state image formed after the two images are defused by the visual center of the brain.

[0101] When the binocular single vision state disappears and binocular multiple shadows appear, the central training target 300 stops moving toward the temporal side and starts moving in the opposite direction back to the starting position.

[0102] FIG. 3b shows a schematic diagram of the left and right visual fields of the trainee when the central training target 300 in FIG. 2 moves diagonally upward from A1 to B1 and A2 to B2, and after it is inversely fused with the visual center of the cerebrum.

[0103] The left and center columns show images of the left and right visual fields, respectively, when the central training target 300 moves from A1, A2 to B1, B2, and then back to the positions of A1, A2. The right column shows the images in the binocular single vision state formed after the two images are reverse-fused by the visual center of the cerebrum.

[0104] When the binocular single vision state disappears and binocular multiple shadows appear, the central training target 300 stops moving upward toward the temporal side and starts moving in the opposite direction back to the starting position.

[0105] FIG. 3c shows a schematic diagram of the left and right visual fields of the trainee when the central training target 300 in FIG. 2 moves diagonally downward from A1 to D1 and A2 to D2, and after it is inversely fused with the visual center of the cerebrum.

[0106] The left and center columns show images of the left and right visual fields, respectively, when the central training target 300 moves from A1, A2 to D1, D2, and then back to the positions of A1, A2. The right column shows the images in the binocular single vision state formed after the two images are reverse-fused by the visual center of the cerebrum.

[0107] When the binocular single vision state disappears and binocular multiple shadows appear, the central training target 300 stops moving downward toward the temporal side and starts moving in the opposite direction back to the starting position.

[0108] As can be seen from the right column of Figures 3a to 3c above, when the central training target is visible to each of the trainee's left and right monocular eyes, the two eyes fuse together to combine the two geometric targets into one complete and clear target as the target continues to move, and multiple shadows appear on the complete and clear target, at which point the movement of the target is stopped.

[0109] It is necessary to explain that, in contrast to the 2D flat target that can only be obtained by the visual processing area of ​​the brain during monocular observation, the formation of a 3D stereo target obtained during binocular observation improves the visual processing function of the brain. Therefore, the central training target 300 of the present invention is It can form a better 3D stereoscopic target, and the training effect can be enhanced compared with the above 2D training target.

[0110] In fact, the visual processing area of ​​the brain continues to function to pay more attention to and maintain the continuity of the stereo target, so the visual processing area of ​​the brain feedback-guids the nuclei of certain extraocular muscles in the brainstem to maintain or move the visual axis of the eyes to maintain the continuity of the stereo target of interest. At this time, both eyes can simultaneously stay still, move inwards (inward movement of the eyes is avoided during training, and the two eyes move inward in opposite directions at the same time), move outwards (outward movement of the eyes is encouraged during training, and the two eyes move outward in opposite directions at the same time), move up, down, left, right, or diagonally at the same time (moving left, right, or diagonally at the same time is avoided during training). Eyes shaft The continuous visual maintenance of the stereo target during movement will feedback guide both eyes to move forward along the original movement trajectory until the limit of the fusion mechanism of the visual processing area of ​​the brain is exceeded, at which point the fused stereo target will be decomposed into two 2D flat targets, resulting in diplopia. Taking advantage of the visual superiority of 3D stereo target over 2D flat target, the visual processing area of ​​the brain will be strengthened, the center of the near reflex pathway will be repeatedly inhibited, the ciliary muscle will be relaxed, and the accommodation of the lens will be restored to the state before the increase, and at the same time, the outward movement of both eyes will be encouraged, thus strengthening the lateral rectus muscle, which is relatively weakened by myopia, and the medial rectus muscle, which is relatively strengthened by myopia.

[0111] Example: Visually perfect and incomplete target patterns for the left and right eyes, respectively. The target pattern may be complete for the left and right eyes respectively, and the goal is for the left and right eyes to combine together two complete target patterns to form one complete (3D) target and background. The target pattern may be incomplete for the left and right eyes respectively, and for example a lion pattern is intermittent, broken and incomplete, and the goal is for the left and right eyes to combine together two broken and incomplete target patterns to form one particular complete (3D) target and background.

[0112] In order to reliably obtain the above-mentioned training effect, the moving speed of the central training target 300 used in the present invention is in the range of 0.1° to 3° per second.

[0113] In addition to using circular targets with complementary contrast as described above, the following categories may also be used: Pattern markers include: animals, plants, landmarks, landscapes, rivers, cars, boats, airplanes, everyday items, restaurants, hotel lobbies and concert halls. These markers may be actual photographed images, painted images or cartoon images.

[0114] Textual symbols, including: Chinese characters, Tang and Song dynasties poetry, three-character classics, etc. Foreign languages, such as English, French, German, Latin, etc.

[0115] Pattern + character combination, for example: lion pattern and Chinese character or foreign character "lion" appearing simultaneously or before and after each other.

[0116] Switch between different combinations in different scenes, for example: pattern vs. pattern (lion then tiger), pattern vs. text (lion pattern and Chinese or foreign language lion text appearing simultaneously or one after the other), text vs. text (Chinese first, then foreign language, etc.).

[0117] When observed from a distance of 45 cm using a tablet computer, the size of the target is approximately 15 mm × 15 mm (based on the relative training distance, the size can be appropriately modified to suit the trainee's visual acuity level and training needs).

[0118] It should be noted that the training target 300 used in the present invention is on a 2D plane and satisfies the length:width of the target≦5:1, or the width:length≦5:1.

[0119] Disturbing symptoms such as dizziness and headaches caused by the brain's difficulty in fusing visual cues seen by the left and right eyes AvoidTherefore, when the trainee fuses the left and right images of the same size to obtain one image, the target on one side can be enlarged or reduced, but the deviation in size must be less than 10%, and the brain is stimulated under the condition that the relative distance and angle between the left and right eyes do not change, thereby achieving the purpose of fusion and training.

[0120] For training target color, background color changes and applications, e.g.: a. The training target is just the outline of a tiger with no color, and gradually the outline is automatically filled in with more and more color until a complete tiger is obtained.

[0121] b. The colors on both sides can be the same or different, achieving overlapping or blending effects such as alternating colors of red, green, blue, yellow, etc. The visual center can also overlap two monocular similar targets of different colors to obtain a composite target with different colors (a blue target overlapped with another monocular green target to obtain a light blue target) to form a complete (3D) specific color target and background.

[0122] c. The color can change shade, for example light green can deepen to green and then to black-green, or from dark to light.

[0123] d. The background color is grayish to reduce unnecessary overly bright light stimuli and to avoid interfering with the trainee's concentration on the central and peripheral training targets.

[0124] Regarding the change in luminance of the training target, the luminance of the target can be changed rhythmically, from a relatively dark state to a bright state, from a relatively bright state to a dark state, or repeated, to avoid excessive pupillary response due to brightness and unnecessary increased accommodation.

[0125] In addition, the static and dynamic modes of the training targets (static, dynamic, combination of static and dynamic, mosaic integration, short film format)

[0126] Training is performed by selecting a fixed or random program of static and dynamic modes of training targets.

[0127] In static training, the target does not move, and neither do the two monocularly visible targets.

[0128] For dynamic training, the targets can be in a gradual or jump movement mode, for example, one monocular training target can be a bird and the other monocular target can be a birdcage (just large enough to fit the bird and visually maintain that the bird is in the cage during training).

[0129] a. The visual target of each monocular is moving.

[0130] b. One monocular target is fixed and the other monocular target is moving.

[0131] c. The visual targets of each monocular move alternately.

[0132] Mixed static and dynamic training: Example 1: In creating a mosaic image, the training target is initially very incomplete, and each image part drawn with a different curve needs to be pieced together bit by bit to finally obtain the complete mosaic image.

[0133] Example 2: Adding shadows around the outline of the training target or adding additional images (e.g. adding a bird on the cow's back, adding a tree next to the cow, etc.).

[0134] Example 3: Using a short animated story format to present targets and training.

[0135] In addition, the display time and movement speed (length of duration) of the training targets can be manipulated to be faster or slower in order to create a more efficient visual impact.

[0136] Since the average blink time is 0.3 to 0.4 seconds, it is desirable to display the target for 0.5 seconds or more. In addition, considering the "Troxler effect," if you focus on a specific target for more than 20 seconds, the visual stimulus will fade and disappear, so it is recommended to display the target for 0.5 seconds or more. Does not move The display time must be controlled to within about 10 seconds.

[0137] First, starting from a slow movement speed, the brain's motor mechanism is used to slowly track the target, and the extraocular muscles that resist the near reflex pathway are moved along the main movement direction, and the minimum distance from the interpupillary distance of the two eyes to the central line of the monocular target is determined, and this is called back fusion. ability The minimum value, i.e., the starting point, is set as the minimum value, and the training is performed along the angle direction of the extraocular muscle connected to the eyeball, and reverse fusion is performed. ability When training is repeated, the tracking speed is gradually increased to the maximum value.

[0138] Once the subject becomes accustomed to relatively fast tracking movements, the visual target changes to a jumping representation, and the brain uses the visual target to scan quickly, Stimulates specific trained extraocular muscles (these extraocular muscles are inhibited by the near reflex pathway). The minimum distance between the pupillary distance of both eyes and the center line of the monocular target is determined, and this is the reverse fusion. ability The minimum value, i.e., the starting point, is set as the minimum value, and the training is performed along the angle direction of the extraocular muscle connected to the eyeball, and reverse fusion is performed. ability When training is repeated, the scanning speed is gradually increased up to the maximum value.

[0139] Regarding the meaning of a series of sequential training symbols, for example, the text of Tang Poetry symbols is a synthesis of images seen by the left and right eyes, and the repeated movement of each symbol forms a complete and coherent meaningful text. The image symbols of various musical instrument items form a complete image using various forms of combination puzzles. It can also be used to train mathematical operation styles, introduce astronomical and historical knowledge, etc.

[0140] In addition, the training visual indicators of the present invention can be combined with audio, and the training visual indicators can be organically combined with audio content, including language commentary, music, or both, to tell a story or to enhance the background with various background music.

[0141] For example, the combination of sheet music and music sounds, the audio can be the music itself, or it can be an introduction to the music background including the composer, the background of the composition, the related story of the song, etc. Purpose: To create a sympathetic effect with the visual target, add background commentary and music, etc. to achieve educational effects, and maintain concentration on training.

[0142] The combination of the above several training methods aims to effectively stimulate the visual processing center of the brain through a highly efficient target presentation method, and avoid the "Troxler effect" caused by a single, stationary target, thereby avoiding visual fatigue, extending the stimulation time, maintaining training concentration, improving attraction, and greatly increasing the stimulation effect per unit time, thus increasing the central inhibition of the near reflex pathway, relaxing the ciliary muscle to return the accommodation of the lens to the state before the increase, strengthening the lateral rectus muscle and strengthening the medial rectus muscle, thereby achieving the purpose of short-time and highly efficient training.

[0143] The present invention adds connection and narrative elements between the training visual symbols, and the elements that can be related can form a logical plot or scene. Through the interactive training media of vivid, interesting and intelligent visual symbols (with associated voice or background music), it can simultaneously achieve the improvement of knowledge level and educational effect (with associated voice or background music), while avoiding carelessness and inefficient training results caused by boring training process.

[0144] When using attractive targets, the target appears in the following way: for example,Formation of 3D stereoscopic targets, appearance-disappearance of targets, color change, expansion-contraction, thick and thin contour lines, alternating dotted and solid lines, adding mosaic patterns, movement, jumping, adding static and related features, contrast (synonyms, antonyms, etc.), etc. In this way, the appearance of the "Troxler effect" can be avoided, the training remains interesting, the brain is continuously stimulated, and reverse fusion can be well maintained, so that the training goal can be achieved efficiently for a longer period of time.

[0145] Importantly, the key functions of peripheral vision are to recognize common structures and shapes, to distinguish between similar shapes and movements, and to form a sense of the visual context. Central vision perception, together with the contributions of peripheral vision, constitutes the panoramic and detailed view that the eye sees every day.

[0146] Due to the spherical shape of the eye and the relationship between the size of the pupil and the relative positions of the lens and peripheral retina in daily life, clinically, the peripheral retina plays an important role in overall vision. eyeball This refers to the range (approximately 25° to 60°) before and after the equator (approximately 43°). Peripheral hyperopic blurring can also cause and worsen the formation and progression of myopia, so weakening or offsetting peripheral hyperopic blurring can help inhibit the formation of pseudomyopia and true myopia.

[0147] Therefore, Fig. 4 shows the results of the training of the central target for one-sided visual field. Providing peripheral training targets, An embodiment for performing peripheral vision training has been given.

[0148] In this embodiment, the distance between the central training targets 300 is 2 to 30 mm greater than the first eye position, and in a state of single binocular vision, the peripheral training targets A and B move to a position 25° to 60° to the temporal side of the visual field with respect to the central training target.

[0149] Here, FIG. 4a shows a situation in which the peripheral training targets A and B are fixed and do not move. 4b to 4d show a case where the peripheral training target B is fixed, the peripheral training target A moves to B, and when A and B overlap, A stops moving. Figures 4e to 4g show that the peripheral training target A moves in the opposite direction away from the training target B, returns to the starting point This shows a situation where A stops moving when A moves to .

[0150] The specially designed peripheral training targets A and B are required to: (1) Background color of peripheral training targets: grayish. (2) Color of peripheral training target: Matte black figures such as cartoon images of horses. (3) Position of peripheral training target: For each eye It is located 25° to 60° temporally in the visual field. (4) Size of the peripheral training target: 16 times the size of the central training target. (5) Static and dynamic movement method of peripheral training target: When the central training target is fixed at a position that increases the interpupillary distance of the first eye position by 2 to 30 mm (not limited to 2 to 30 mm), and a state of single vision with both eyes is obtained.

[0151] The present invention can be realized by a complete set of application program software, which can be used on computers, mobile phones, tablet PCs, etc. etc. The trainee can freely select the training content he or she needs by directly operating these interactive terminals, and the training content can be displayed on a computer display screen, a television display screen, or a projection screen. etc. You can carry out the training by looking at the training targets above, and you can change the targets and background music according to your actual needs during the training process.

[0153] Through this series of special training methods, the following goals can be achieved with high efficiency:

[0154] Since each eye can only see targets that appear on the temporal side, the visual center of the cerebral cortex must undergo visual inverse fusion to meet the requirements of binocular single vision and stereoscopic vision. ability , Hering's Law, and Sherrington's Law are applied to instruct the brainstem to achieve the following effect:

[0155] 1. It controls and inhibits the center of the near reflex pathway, making it less active. 2. Ciliary muscle By preventing contractions and spasms , you can maintain a relaxed state. 3. The curvature of the lens surface and the anterior-posterior diameter are returned to a state without additional accommodation, thereby achieving the elimination of unnecessary accommodation. 4. Hering's law is applied to the relevant extraocular muscle nuclei in the brainstem. and Sherrington's Law This allows both eyes and the temporal field of view Related to the lateral rectus , superior rectus muscle, inferior rectus muscle and nose side field of view Related to the medial rectus , superior oblique muscle, inferior oblique muscle Instruct the patient to stimulate the Left and right Eyes When observing and tracking a target This allows the patient to maintain a single binocular vision, thus eliminating the overdeveloped medial rectus muscle. , superior oblique muscle, inferior oblique muscle, and tense extraocular muscles continuously The lateral rectus muscle is suppressed and weakened at the same time. , superior and inferior rectus muscles Strengthens the muscles and improves decreased muscle tone. 5. Improves poor vision, offsets pseudomyopia, and slows the progression of true myopia By them eye axis of Slows or stops excessive elongation. 6. Significantly reduce the harmful changes in ocular structure caused by the worsening of myopia due to increased accommodation, and reduce the adverse effects and risk rate of complications of the eyes, especially the retina, in the future, such as: retinal hole, retinal detachment, retinal hemorrhage, vitreous hemorrhage, vascular proliferation caused by retinal cracks, glaucoma, etc.
