Description

Technical Field

[0001] The present invention relates to a vision correction device and a correction method which can improve and correct the vision of patients with myopia, strabismus, astigmatism, presbyopia and cataract through physical therapy means, and belongs to the field of eye vision therapy device manufacturing. Background Art

[0002] CN118058954A, entitled "A method for improving vision by extraocular muscle movement and its application", has the following steps: moving the viewed image left and right and up and down to shorten the distance between the lens and the retina to improve vision; since there are six muscles on the outer wall of each human eyeball, namely the medial rectus muscle, lateral rectus muscle, superior rectus muscle, inferior rectus muscle, superior oblique muscle and inferior oblique muscle, these muscles contract and relax under the control of the optic nerve to play the role of rotating the eyeball, when the viewed image moves left and right and up and down, the eyeball will rotate due to viewing; when the viewed image moves outward, the eyeball will rotate outward, and the lateral rectus muscle and the medial rectus muscle will contract; the contraction of the extraocular muscles will pull the eye lens toward the retina, thereby shortening the length between the lens and the retina, so that the line of sight can be focused on the retina, and the distant image can be seen clearly; according to the principle of optometry, myopia is reduced by 300 degrees for every millimeter reduction in the length of the eye axis; if this method is performed frequently, vision can be improved. Its shortcomings are: people cannot watch the image moving left and right and up and down at the same time; secondly, when the image being watched moves left and right, up and down, if the eyeballs rotate due to watching, it will cause the eyes to become tired, not only will the superior rectus and inferior rectus muscles of the eyes not be contracted, but the superior rectus and inferior rectus muscles of the eyes will also be overly tired, resulting in ineffective eye vision training (physical therapy) and even increasing the burden on the eyes. Summary of the invention

[0003] Design purpose: To avoid the shortcomings of the background technology, a vision correction device and correction method are designed that can correct myopia, strabismus, astigmatism, presbyopia and cataracts unconsciously by watching 3D videos played on a flat-panel display on a 3D viewer.

[0004] Design plan: The abductor and adductor muscles of the eyeball are the medial rectus, lateral rectus, superior rectus, inferior rectus, superior oblique and inferior oblique muscles. These six muscles ensure that the eyes rotate their sight in different directions to obtain a comprehensive field of vision. Their functions are as follows: First, the superior rectus and inferior rectus are the main abductor fascia that make the eyeball move up or down. When a person's eyes want to look at the top of the head or the bottom of the feet, these two abductor fascia will play a role. Second, the medial rectus and lateral rectus are the main abductor fascia that control the left and right movement of the eyeball. When a person's eyes want to look to the left or right, these two abductor fascia will play a role. Third, the superior oblique and inferior oblique muscles are the main abductor fascia that make the eyeball rotate upward or downward. When a person's eyes want to see above or below, these two abductor fascia will play a role. From the structure of the eye, it is found that the six abductor fasciae of the eye are closely related to the imaging focal point. During binocular vision, the six abductor fasciae must coordinate with each other to keep the eyeball balanced, symmetrical, and able to make corresponding adjustments according to the distance and size of the object. The six abductor fasciae of the eyeball will automatically reflexively coordinate according to visual stimulation to achieve the best visual effect. On the contrary, if the six abductor fasciae of the eye are deformed, the imaging focal point will change, leading to myopia, hyperopia, strabismus, astigmatism, presbyopia, and cataracts.

[0005] 1. The cause of myopia is: when the human eye looks at an object, the image focal point is in front of the retina. The greater the distance between the focal point and the retina, the higher the degree of myopia. Conversely, the closer the image focal point is to the retina, the smaller the degree of myopia. When the image focal point is on the retina, myopia does not exist, that is, vision returns to normal.

[0006] 2. The cause of hyperopia is: when the human eye looks at an object and the image is focused on the retina, the greater the distance between the focus point and the retina, the higher the degree of hyperopia; conversely, the closer the image is focused on the retina, the smaller the degree of hyperopia; when the image is focused on the retina, there is no hyperopia, that is, vision returns to normal.

[0007] 3. The causes of strabismus are: First, genetic factors. If both parents or one of them has strabismus, the possibility of their children inheriting the disease is relatively high, higher than that of the general population; second, bad eye habits, such as myopia and hyperopia without corresponding treatment measures, and severe symptoms, which may also lead to esotropia or exotropia; third, abnormalities in the delivery process: if there are factors during the delivery process, such as dystocia, intrauterine asphyxia, and cesarean section, it may cause damage to the eyes, causing abnormalities in the nerves and muscles that control the eye, thus forming strabismus.

[0008] 4. The causes of astigmatism are: First, genetic factors. If both parents or one of them has astigmatism, the possibility of their children inheriting it is relatively high, and the probability of astigmatism is relatively high; second, eye trauma. If the eye is traumatized, irregular scars will form on the conjunctiva, and astigmatism will also form at the scar; third, bad eye habits. If you have close contact with electronic products for a long time, or sit incorrectly when reading, or read with your body tilted or sideways for a long time, it may cause astigmatism; fourth, age factors: the risk of astigmatism caused by the cornea. With age, the lens will have varying degrees of turbidity, which may increase the risk of astigmatism; fifth, if the child is obese, the astigmatism detection rate is also relatively high in adolescence; sixth, nutritional factors. If you do not pay attention to your personal diet, are overly picky or have malnutrition, it may lead to a decrease in corneal hardness, which will increase the risk of astigmatism; seventh, other diseases: eye astigmatism may also be caused by other diseases, such as Down syndrome, spina bifida, nystagmus and other diseases may induce astigmatism.

[0009] 5. The causes of presbyopia are: First, age factors. With age, the lens of the eye gradually hardens and thickens, and the adjustment ability of the eye muscles also decreases, resulting in a decrease in zoom ability. Therefore, when looking at close objects, since the image cannot be fully focused when projected on the retina, close objects will become blurry; second, refractive error. People with hyperopia will experience presbyopia earlier than those with myopia, and people who wear contact lenses will also experience presbyopia earlier; third, drug factors. Taking diuretics, antidepressants, antispasmodics, etc. will affect the ciliary muscles, leading to early presbyopia; fourth, the way of using the eyes. Long-term close-up fine work or excessive use of the eyes will increase the chance of presbyopia; fifth, geographical location. People living near the equator or in high-temperature areas will experience presbyopia earlier because high temperatures will affect the adjustment of the lens; sixth, congenital factors. People with congenital flat corneas, flat lens problems or corneal trauma are prone to presbyopia.

[0010] 6. The cause of cataracts is a degenerative disease in which the transparency of the lens changes or the color becomes abnormal, which subsequently causes a decline in the optical quality of the human eye.

[0011] The above six eye diseases are closely related to the structure of the eye. The research and development test found that people with normal vision have a relatively healthy state of the six abductor fascia of the eyeball; people with vision problems have a decline in the muscle function of the six abductor fascia of the eyeball. The older they are, the more serious the decline in muscle function. Not only does it take a long time for vision physical therapy to recover, but it also takes a longer time to fix the six abductor fascia muscles (no recurrence) after vision returns to normal.

[0012] To this end, the present invention aims at the deficiencies existing in the background technology, and based on the theory of eye vision training (physical therapy) proposed by Bates, through repeated theoretical verification and repeated experimental verification, a method is found that can effectively avoid the deficiencies existing in the background technology and verify the feasibility of Bates theory. The scheme is as follows: Solution 1: Set the left and right synchronized images in the 3D video playback software to be able to move synchronously left and right or move oppositely left and right, and the movement amplitude cannot exceed the maximum range of the human eye looking directly at the screen. The purpose of this design is: when the 3D picture planes displayed on the flat panel display, that is, the left picture and the right picture move towards each other, it is equivalent to zooming in on the 3D picture being watched; when the left picture and the right picture move oppositely, it is equivalent to zooming out on the 3D picture being watched, and the alternation between zooming in and zooming out constitutes a complete 3D video training software. Before watching the video, the viewer adjusts the focal length of the focusing device composed of the zoom shell and the viewing shell in the 3D film viewer to make the image slightly blurred when the viewer watches it, and then opens the eyes wide with naked eyes and repeatedly watches the video images until they can see clearly. After the training, the myopia degree of the viewer's glasses should be 50 to 200 degrees lower than the degree of normal glasses, and then adjusts the focal length of the focusing device composed of the zoom shell and the viewing shell in the 3D film viewer until the image is slightly blurred again when the viewer watches it, and then opens the eyes wide with naked eyes. Eyes, watch the video images repeatedly until they can see clearly. After the training, the myopia degree of the glasses worn by the viewer is reduced by 50 to 200 degrees based on the degree of the glasses worn after the previous training. This cycle is repeated until the focal length of the 3D viewer is adjusted to the maximum. Then open your eyes wide with naked eyes and watch the video images repeatedly. In this way, the contraction of the six abductor and adductor muscles that make up the eyeball can be effectively trained, and the imaging focus can be close to the retina or overlapped with the retina, until the desired vision value is reached.

[0013] Solution 2: Driven by the control motor, the viewing lens board in the 3D viewer repeatedly deepens or shortens the distance between the viewing lens board and the viewer's viewing window according to the set time and speed, just like deepening or shortening the 3D image played on the flat-panel display and the viewer's viewing vision. Before watching, the viewer adjusts the focal length of the focusing device composed of the zoom shell and the viewing shell in the 3D viewer to make the image slightly blurred when the viewer watches it, and then repeatedly watches the video image with naked eyes wide open until the 3D video image can be seen clearly. After the training, the myopia degree of the glasses worn by the viewer should be 50 to 200 degrees lower than that of the normal glasses; then adjust the focal length of the 3D viewer until the image is slightly blurred again when the viewer watches it, and then repeatedly watches the video image with naked eyes wide open. Until they can see clearly, the myopia degree of the glasses worn by the viewer after the training is reduced by another 50 to 200 degrees on the basis of the previous reduction, and this cycle is repeated until the focal length of the 3D viewer is adjusted to the maximum. Then the viewer watches the video image repeatedly with naked eyes wide open until it is clear. In this way, the contraction of the six abductor and adductor muscles that make up the eyeball can be effectively trained, and the imaging focus can be close to or coincide with the retina to achieve the desired vision value. However, at this time, it is necessary to persist in training for several months to consolidate the training results.

[0014] Compared with the background technology, the present invention has the following advantages: first, for teenagers: if the myopia of the eyes is below 600 degrees, the myopia can be reduced by 100 to 300 degrees, astigmatism can be significantly improved, and strabismus can be improved after 30 days of treatment with the vision correction device of the present invention; if the myopia of the eyes is above 600 degrees, the myopia can be reduced by 80 to 200 degrees, astigmatism can be significantly improved, and strabismus can be improved after 30 days of treatment with the vision correction device of the present invention; second, for middle-aged and elderly people: if the myopia of the eyes is below 600 degrees, the vision correction device of the present invention can be used for physical treatment of 30 days. After 30 days of physical treatment with the vision correction device of the present invention, myopia can be reduced by 80 to 250 degrees, astigmatism and presbyopia can be significantly improved, and cataracts can be improved to some extent; if the myopia of the eyes is above 600 degrees, 30 days of physical treatment with the vision correction device of the present invention can reduce the myopia by 50 to 150 degrees, astigmatism and presbyopia can be significantly improved, and cataracts can be improved to some extent; thirdly, the present invention uses the VR film viewer used for watching stereoscopic videos for vision correction, which has achieved unexpected positive technical and social effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 This is a schematic diagram of a vision correction device.

[0016] Figure 2 This is a diagram of the structure of the eye. DETAILED DESCRIPTION

[0017] Example 1: Refer to the attached Figure 1A vision corrector comprises a headband 3, a binocular lens assembly is mounted on one end of a corrector housing 1, the spacing between binocular lenses in the binocular lens assembly is adjusted by an adjusting knob 5, the focal length of each eyepiece in the binocular lens assembly is adjusted by a focal length adjusting knob 6, a binocular lens eye cover 2 is connected to one end surface of the corrector housing, a 3D video display screen 4 is mounted on the other end of the corrector housing 1, and the corrected eyes watch the 3D video images played on the 3D video display screen 4 through the binocular lenses to achieve the correction of myopia, presbyopia, astigmatism and hyperopia.

[0018] The lens in the binocular lens is a double-sided aspherical lens. The screen resolution of the 3D video display screen 4 is equal to or greater than 4K. The left and right images played by the 3D video player software built into the 3D video display screen 4 move toward and away from each other alternately. The left and right images move toward each other, which means that the images are close to the binoculars, and the opposite is far away from the binoculars. The amplitude of the movement toward and away from each other is proportional to the degree of myopia, presbyopia, and astigmatism.

[0019] The 3D video display screen 4 has a built-in 3D video player software. After the 3D player software is placed, the 3D picture, i.e., the left picture and the right picture, can be displayed on the display screen. The present invention designs the left picture and the right picture played by the 3D video player software on the flat panel display screen to move synchronously towards each other or move synchronously in the opposite direction, and the two are alternated continuously. The time for the left picture and the right picture to move towards each other and in the opposite direction (i.e., the amplitude of the movement) is proportional to the degree of myopia and presbyopia. The technology of designing the video picture to move towards each other or in the opposite direction is itself an existing technology and is not described here. For example: 1. Adobe Premiere Pro: In this software, after selecting the clip you want to move, open the "Move / Scale" option, and the moving operation can be achieved by dragging the picture. 2. Final Cut Pro X: By selecting the target clip, clicking the "Deform" option, and then in the "Position" drop-down menu, find and move the picture to the desired position. 3. iMovie: When using this software, after selecting the target clip, open the "Adjustment" tab and adjust the picture position by sliding the "Offset" slider. 4. Filmora: The operation is more intuitive. First, select the target clip, click the "Motion" option, and use manual mode or preset mode to easily move the picture.

[0020] Embodiment 2: A correction method of a vision correction device, 1) A 3D video display screen has built-in 3D video playback software and 3D movies, and then after selecting the 3D video to be watched, click to play, at this time adjust the distance between the binocular lenses to match the viewer's pupil distance, and then adjust the focal length of the binocular lenses so that the image on the screen watched by the viewer is in a clear state or slightly unclear state; 2) The person being corrected watches the 3D video screen played on the display screen through the binocular lenses, or the person being corrected watches the 3D movie screen through the binocular lenses, which is a combination of intermittent left-right opposite movement and intermittent left-right opposite movement, and both The left and right images are displayed on the display screen for the same time and alternately at the same time; 3) The person being corrected watches the 3D video image with naked eyes wide open, and watches it many times until the image can be seen clearly again, and then adjusts the binocular focal length until the image is slightly blurred when the person being corrected watches through the binocular lens, and then watches the 3D video image with naked eyes wide open until the image can be seen clearly again, and so on, until the binocular focal length is adjusted to the maximum, and then watches the video image with naked eyes wide open until the image can be seen clearly again.

[0021] The amplitude of the left and right images in the 3D images played by the 3D video display screen cannot exceed the maximum range of the eyes of the person being corrected to look directly at the screen. After the person being corrected corrects his vision by watching the vision corrector, the myopia of the glasses he wears is 50 to 100 degrees lower than the glasses he wore before correction. The myopia of the glasses worn by the person being corrected after each stage of focus correction is 50 to 200 degrees lower than the glasses worn after the correction in the previous stage, until the correction is completed.

[0022] The 3D video playback software designs the left and right images of the 3D film to be played as a combination of left and right synchronous images moving in opposite directions, and the left image and the right image are displayed on the flat screen at the same time and alternately at the same time (that is, the left image and the right image on the screen move in the same direction for 0.5 to 1 second or several seconds, and then move in the opposite direction for 0.5 to 1 second or several seconds, if it is cyclic; or the left image and the right image on the screen move in the same direction for 0.5 to 1 second or several seconds, pause for 0.5 to 1 second or several seconds, then move in the opposite direction for 0.5 to 1 second or several seconds, pause for 0.5 to 1 second or several seconds, and then move in the opposite direction for 0.5 to 1 second or several seconds, and then pause for 0.5 to 1 second or several seconds. seconds, if looped); 3) Before watching the video, the viewer first adjusts the focus of the 3D viewer to make the image slightly blurred when the viewer is watching, and then watches the 3D video image with naked eyes wide open, through multiple viewings (usually once or twice a day, 30-60 minutes each time) until the image can be seen clearly again; then adjust the focus of the 3D viewer until the image is slightly blurred again when the viewer is watching, and then watch the 3D video image with naked eyes wide open until the image can be seen clearly again, and repeat this cycle until the focus of the 3D viewer is adjusted to the maximum, and then watch the video image with naked eyes wide open until it can be seen clearly again.

[0023] The amplitude of the movement of the left and right images in the played 3D image towards or away from each other cannot exceed the maximum range of the human eye viewing the screen directly.

[0024] After the film viewer has trained at the focal length adjusted by the film viewer, the myopia of the glasses he wears is 50 to 200 degrees lower than the normal glasses. Only in this way can the effect of the training be guaranteed. If after the training, the glasses still have the same degree as before the training, it is almost equivalent to a waste of training. In other words, the myopia of the glasses worn by the film viewer after each stage of the training at the focal length adjusted by the film viewer is 50 to 200 degrees lower than the glasses worn after the previous stage of training, until the end of the training.

[0025] Example 3: Refer to the attached Figure 2. A vision corrector, wherein a binocular lens assembly is mounted at one end of the corrector housing 1, and the spacing between binocular lenses in the binocular lens assembly is adjusted by an adjusting knob 5, and the focal length adjustment between the lens in the binocular lens assembly and the screen cloth is achieved by a controller and a driver, that is, the focal length adjustment knob 6 is achieved by a controller and a driver, and the controller 7 is mainly composed of a time controller and a speed controller, both of which are prior arts and are not described here. The driver is a micro motor, and the micro motor can be a servo motor or a synchronous motor, and its power supply is derived from a battery provided by a 3D video display screen 4. A binocular lens eye cover 2 is connected to one end face of the corrector housing, and a 3D video display screen 4 is mounted at the other end of the corrector housing 1. The corrected eyes watch the 3D video images played on the 3D video display screen 4 through the binocular lenses to achieve correction of myopia, presbyopia, astigmatism, and hyperopia.

[0026] Before watching the video, the person who is being corrected adjusts the focal length of the vision corrector to a state where the image is slightly blurred when the person is watching it, then starts the controller, which instructs the micromotor to drive the lens to move forward and backward according to the set time and speed, and the person who is being corrected watches the 3D video image with naked eyes wide open until he can see the image clearly again and again; then the focal length of the vision corrector is adjusted to a state where the image is slightly blurred when the person is watching it, then starts the controller, which instructs the micromotor to drive the lens to move forward and backward according to the set speed and time, and the person who is being corrected watches the video image with naked eyes wide open until he can see the image clearly again and again, and repeats this cycle until the focal length of the vision corrector is adjusted to the maximum, and then the person who is being corrected watches the video image with naked eyes wide open until he can see it clearly again and again, until the clarity expected by the person who is being corrected is reached, and then continuous correction is performed for several months as needed.

[0027] It should be noted that: 1) When the viewer first uses the focus adjustment distance selected by the viewer for training, the myopia degree of the glasses worn is 50 to 200 degrees lower than the normal glasses. 2) After each stage of the viewer's focus adjustment training, the myopia degree of the glasses worn by the viewer is 50 to 200 degrees lower than the glasses worn after the previous stage of training, until the end of the training.

[0028] It should be noted that the "flat panel display" mentioned in the present invention refers to a display screen that can play 3D images and videos, including but not limited to flat panel displays, smart phones, and non-smart phones.

[0029] The "correction" mentioned in the present invention refers to the training (exercise) of the six abductor fasciae muscles of the human eyeball by watching 3D video images in a vision corrector. Through training, the six abductor fasciae muscles can be improved and rehabilitated, thereby improving and rehabilitating myopia, hyperopia, strabismus, astigmatism, presbyopia and cataracts.

[0030] The "left picture and the right picture move towards and inversely alternately" mentioned in the present invention means that the left picture and the right picture of the flat panel display screen move towards or inversely for 1 second or several seconds within a set time, then start to move inversely or towards each other for 1 second or several seconds, and then move towards or inversely for 1 second or several seconds, and so on. The length of time for the left picture and the right picture to move towards or inversely depends on the degree of the trained eyes (myopia, hyperopia, presbyopia). If the degree of myopia, hyperopia, presbyopia is small (low), the relative movement time of the left and right pictures is short, and if the degree of myopia, hyperopia, presbyopia is large (high), the relative movement time of the left and right pictures is long, but the longest movement time cannot exceed the line of sight of the human eye.

[0031] The "3D images" described in the present invention refer to 3D film and television works, which are films, TV series, cartoons and other film and television works produced using three-dimensional technology (such as 3D modeling, animation, special effects, etc.), as well as 3D films shot using 3D technology.

[0032] The invention is still in the experimental stage for hyperopia training because there are relatively few hyperopia patients and they think that it has little impact on their lives. Therefore, the final result has not yet been achieved.

[0033] The "isochronous alternation between the two" mentioned in the present invention means that the time for the left and right images displayed on the display screen to move toward each other at the same time is equal to the time for the left and right images to move in the opposite direction, and the two change alternately. For example, the left and right images move toward each other for 0.5 to 1 second or several seconds, and then move in the opposite direction for 0.5 to 1 second or several seconds, that is, return to the starting point; then move toward each other for 0.5 to 1 second or several seconds, and then move in the opposite direction for 0.5 to 1 second or several seconds, and so on, forming a continuous 3D display picture.

[0034] The "watching video images with naked eyes wide open" mentioned in the present invention generally refers to watching video images with naked eyes wide open. The effect of watching directly with eyes wide open is: the action of opening eyes wide drives the superior rectus and inferior rectus muscles to expand up and down, while driving the medial rectus, lateral rectus, superior rectus, inferior rectus, superior oblique and inferior oblique muscles to work together and keeping eyes wide open as much as possible, so that the originally changed functions of the medial rectus, lateral rectus, superior rectus, inferior rectus, superior oblique and inferior oblique muscles are gradually improved through uninterrupted daily training. Therefore, when training with eyes wide open, do not move the eyeballs left and right and up and down, otherwise not only the training effect is not good, but it may also aggravate eye fatigue.

[0035] It should be understood that although the above embodiments provide a relatively detailed textual description of the design ideas of the present invention, these textual descriptions are only simple textual descriptions of the design ideas of the present invention, rather than limitations on the design ideas of the present invention. Any combination, addition or modification that does not exceed the design ideas of the present invention shall fall within the protection scope of the present invention.
