Contrast balance training method and system for two eyes in fovea centralis and peripheral visual fields

Abstract

The invention provides a fovea centralis and peripheral view binocular contrast balance training method and system, and the method comprises the steps: setting an initial contrast in a fovea centralis region, carrying out the multi-time adjustment through dynamic Gabor spot stimulation and user feedback information, obtaining a first binocular contrast balance point, taking the first binocular contrast balance point as a reference, and carrying out the training of the fovea centralis and peripheral view binocular contrast balance. A second binocular contrast balance point and contrast balance states of all directions of the inner ring are obtained in the inner ring area according to a central concave area training mode, and in the same way, contrast balance points of the middle ring and the outer ring and corresponding contrast balance states are correspondingly obtained. Starting from a central concave area with most sensitive visual perception, the method is gradually expanded to a peripheral visual field area. In each training stage, the balance point of the two eyes in the previous area is used as a reference, and the balance and coordination of the contrast of the two eyes are gradually improved. Meanwhile, a self-adaptive feedback mechanism is introduced, so that effect unevenness possibly caused by standardized training is avoided.

Description

Technical Field

[0001] This invention relates to the field of visual training technology, and in particular to a method and system for training binocular contrast balance between the fovea and peripheral vision. Background Technology

[0002] In recent years, the prevalence of myopia has continued to rise globally, especially among adolescents, becoming a serious public health problem. Traditional myopia correction methods, such as eyeglasses, contact lenses, and surgery, primarily target the optical correction of myopia; however, they do not fundamentally address the binocular coordination issues related to the fovea and peripheral vision during the development of myopia. Although these methods can effectively improve vision, they fail to effectively intervene in the eye's retinal accommodation mechanisms, particularly regarding binocular visual integration in the peripheral vision, and thus remain limited.

[0003] The development of myopia is closely related to excessive eyeball extension and retinal defocusing, especially the blurring and incoordination of peripheral visual perception, which can accelerate the progression of myopia. Therefore, how to improve binocular visual coordination through scientific training methods, especially enhancing the contrast balance and visual integration ability of foveal and peripheral visual perception, has become an urgent problem to be solved in the field of myopia prevention and control.

[0004] Therefore, providing a method and system for training binocular contrast balance in the fovea and peripheral vision to solve the above problems is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a method for training binocular contrast balance between the fovea and peripheral visual fields. This method is logically clear, starting with the fovea region, where visual perception is most sensitive, and gradually expanding to the peripheral visual field. Each training stage uses the binocular balance point of the previous region as a benchmark, progressively improving binocular contrast balance and coordination. This design ensures the scientific and rational nature of the training process, avoids overstimulation, and gradually improves visual integration ability, conforming to the natural laws of visual adaptation.

[0006] A method for training binocular contrast balance between the fovea and peripheral visual fields includes the following steps: In the foveal region, the initial contrast of the foveal region is set, and the phase-matched targets are adjusted multiple times through dynamic Gabor spot stimulation and user feedback information so that the two eyes are in a phase-matched balance state, thus obtaining the first binocular contrast balance point. In the inner circle region, the initial contrast of the inner circle region is set according to the first binocular contrast balance point. The phase-same targets in multiple positions of the inner circle are adjusted multiple times according to the dynamic Gabor spot stimulation and the user feedback information so that the two eyes are in a phase-same balance state, thereby obtaining the second binocular contrast balance point and the contrast balance state of each position of the inner circle. In the middle circle region, the binocular contrast is adaptively adjusted according to the first rule based on the second binocular contrast balance point and the contrast balance state of each position in the inner circle, and the initial contrast of the middle circle region is set. Based on the dynamic Gabor spot stimulation and the user feedback information, the phase-opposite targets in multiple positions in the middle circle are adjusted multiple times to make the two eyes in a phase-opposite balance state, so as to obtain the third binocular contrast balance point and the contrast balance state of each position in the middle circle. In the outer ring region, the binocular contrast is adaptively adjusted according to the second rule based on the third binocular contrast balance point and the contrast balance state of each position in the middle ring. The initial contrast of the outer ring region is set, and the phase-opposite targets in multiple positions in the outer ring are adjusted multiple times according to the dynamic Gabor spot stimulation and the user feedback information so that the two eyes are in a phase-opposite balance state, thus obtaining the fourth binocular contrast balance point and the contrast balance state of each position in the outer ring.

[0007] Preferably, it further includes: Monitor the user's eye movement trajectory; The first determination is whether the user's eye movement trajectory conforms to a preset movement trajectory; If the first judgment result is negative, then retraining is performed until the user's eye movement trajectory matches the preset movement trajectory.

[0008] Preferably, after determining whether the user's eye movement trajectory conforms to a preset movement trajectory, the method further includes: Divided into four quadrants based on the user's field of vision; Based on the spatial position of the outermost viewpoint in each quadrant, obtain the vertical pixel distance between the spatial position of the outermost viewpoint in each quadrant and the preset central concave point, and set the deviation range benchmark according to the vertical pixel distance; If the first judgment result is negative, the second judgment is whether the user's eye movement trajectory is greater than the deviation range benchmark. If so, it is defined as an abnormal user eye movement deviation. The third step is to determine whether the user feedback information is correct. If so, retrain until the user's eye movement trajectory matches the preset movement trajectory.

[0009] Preferably, the step of repeatedly adjusting the visual targets with the same phase through the dynamic Gabor spot stimulation and the user feedback information to achieve a first binocular contrast balance point by having both eyes in a balanced state of phase equality includes the following steps: Based on the initial contrast of the foveal region, the same phase targets are adjusted multiple times according to the preset rule of increasing the contrast of abnormal eyes and simultaneously decreasing the contrast of normal eyes through the dynamic Gabor spot stimulation and the user feedback information. When both eyes are integrated, the center of the visual target appears as a white line, which is defined as a state of phase balance between the two eyes. Under the condition that the phases of both eyes are equal and balanced, the contrast of the normal eye and the contrast of the abnormal eye are obtained as the first binocular contrast balance point.

[0010] Preferably, the step of repeatedly adjusting the phase-equal targets at multiple locations within the inner circle based on the dynamic Gabor spot stimulation and the user feedback information, so that both eyes are in a phase-equal balance state, and obtaining the second binocular contrast balance point and the contrast balance state at each location within the inner circle, includes the following steps: Based on the initial contrast of the inner circle region, the phase-same targets in multiple positions of the inner circle are adjusted multiple times according to the preset rule of increasing the contrast of abnormal eyes and simultaneously reducing the contrast of normal eyes through the dynamic Gabor spot stimulation and the user feedback information. When both eyes are integrated, the center of the visual target appears as a white line, which is defined as a state of phase balance between the two eyes. Under the condition that the phases of both eyes are equal and balanced, the contrast of the normal eye and the contrast of the abnormal eye are obtained as the second binocular contrast balance point; Fourth, determine whether the user feedback information is correct; The contrast balance state of each direction of the inner circle is obtained based on the fourth judgment result.

[0011] Preferably, in the middle circle region, the binocular contrast is adaptively adjusted according to the first rule based on the second binocular contrast balance point and the contrast balance state of each direction in the inner circle, and the initial contrast of the middle circle region is set, including the following steps: If the fourth determination result is yes, the viewpoint with the same phase on the corresponding inner circle orientation is defined as the first viewpoint; If the first determination result is negative, the viewpoint with the same phase on the corresponding inner circle azimuth is defined as the second viewpoint; Based on the initial contrast of the inner circle region, the first visual target is adjusted by a preset rule that increases the contrast of the abnormal eye and simultaneously decreases the contrast of the normal eye with an adjustment range of N, through the dynamic Gabor spot stimulation and the user feedback information. Based on the initial contrast of the inner circle region, the second visual target is adjusted according to a preset rule that increases the contrast of the abnormal eye and simultaneously reduces the contrast of the normal eye with an adjustment range of 2N, based on the dynamic Gabor spot stimulation and the user feedback information. The initial contrast of the middle circle region is set based on the adjusted first and second visual targets.

[0012] Preferably, the step of repeatedly adjusting the visual targets with opposite phases at multiple locations in the central circle based on the dynamic Gabor spot stimulation and the user feedback information, so that the two eyes are in a balanced state of opposite phases, and obtaining the third binocular contrast balance point and the contrast balance state of each location in the central circle, includes the following steps: Based on the initial contrast of the central region, the same phase targets are adjusted multiple times according to the preset rule of increasing the contrast of abnormal eyes and simultaneously decreasing the contrast of normal eyes through the dynamic Gabor spot stimulation and the user feedback information. When both eyes are integrated, the center of the visual target appears as a white line, which is defined as a state of phase imbalance between the two eyes. In the binocular phase-opposite balance state, the contrast of the normal eye and the contrast of the abnormal eye are obtained as the third binocular contrast balance point; Fifth, determine whether the user feedback information is correct; The contrast balance state of each direction of the middle circle is obtained based on the fifth judgment result.

[0013] Preferably, in the outer ring region, the binocular contrast is adaptively adjusted according to the second rule based on the third binocular contrast balance point and the contrast balance state of each direction in the middle ring region, and the initial contrast of the outer ring region is set. If the fifth judgment result is yes, the viewpoint with the same phase on the corresponding center circle azimuth is defined as the third viewpoint; If the fifth judgment result is negative, the viewpoint with the same phase at the corresponding center circle position is defined as the fourth viewpoint; Based on the initial contrast of the inner circle region, the third visual target is adjusted by a preset rule that increases the contrast of the abnormal eye and simultaneously decreases the contrast of the normal eye with an adjustment range of M, through the dynamic Gabor spot stimulation and the user feedback information. Based on the initial contrast of the inner circle region, the fourth visual target is adjusted according to a preset rule that increases the contrast of the abnormal eye and simultaneously reduces the contrast of the normal eye with an adjustment range of 2M, based on the dynamic Gabor spot stimulation and the user feedback information. The initial contrast of the outer ring region is set based on the adjusted third and fourth visual targets.

[0014] Preferably, the visual targets with opposite phases at multiple locations in the middle circle are adjusted multiple times based on the dynamic Gabor spot stimulation and the user feedback information, so that the two eyes are in a balanced state of opposite phases, thereby obtaining the fourth binocular contrast balance point and the contrast balance state of each location in the middle circle. Based on the initial contrast of the outer ring region, the same phase targets are adjusted multiple times according to the preset rule of increasing the contrast of abnormal eyes and simultaneously decreasing the contrast of normal eyes through the dynamic Gabor spot stimulation and the user feedback information. When both eyes are integrated, the center of the visual target appears as a white line, which is defined as a state of phase imbalance between the two eyes. In the binocular phase-opposite balance state, the contrast of the normal eye and the contrast of the abnormal eye are obtained as the fourth binocular contrast balance point; Sixth, determine whether the user feedback information is correct; The contrast balance state of each direction of the outer ring is obtained based on the sixth judgment result.

[0015] A binocular contrast balance training system for foveal and peripheral vision includes: The foveal training module is used to set the initial contrast of the foveal region and adjust the phase-matched targets multiple times through dynamic Gabor spot stimulation and user feedback information so that the two eyes are in a phase-matched balance state, thus obtaining the first binocular contrast balance point. The inner circle training module is used to set the initial contrast of the inner circle region according to the first binocular contrast balance point, and adjust the phase-same targets in multiple positions of the inner circle multiple times according to the dynamic Gabor spot stimulation and the user feedback information, so that the two eyes are in a phase-same balance state, and obtain the second binocular contrast balance point and the contrast balance state of each position of the inner circle. The middle circle training module is used to adaptively adjust the contrast of the two eyes according to the second binocular contrast balance point and the contrast balance state of each position of the inner circle in the middle circle region according to the first rule, and set the initial contrast of the middle circle region. Based on the dynamic Gabor spot stimulation and the user feedback information, the phase-opposite targets in multiple positions of the middle circle are adjusted multiple times to make the two eyes in a phase-opposite balance state, so as to obtain the third binocular contrast balance point and the contrast balance state of each position of the middle circle. The outer ring training module is used to adaptively adjust the binocular contrast in the outer ring region according to the second rule based on the third binocular contrast balance point and the contrast balance state of each position in the middle ring. It also sets the initial contrast of the outer ring region and adjusts the phase-opposite targets in multiple positions in the outer ring multiple times according to the dynamic Gabor spot stimulation and the user feedback information, so that the two eyes are in a phase-opposite balance state, thereby obtaining the fourth binocular contrast balance point and the contrast balance state of each position in the outer ring.

[0016] The present invention provides a binocular contrast balance training method for the fovea and peripheral visual fields. The method involves setting an initial contrast in the fovea region, making multiple adjustments based on dynamic Gabor spot stimulation and user feedback to obtain a first binocular contrast balance point. Using the first binocular contrast balance point as a reference, the method is applied to the inner circle region in the same way as the fovea region training method to obtain a second binocular contrast balance point and the contrast balance state of each position in the inner circle. This process is repeated to obtain the corresponding contrast balance points and contrast balance states of the middle and outer circles.

[0017] This invention begins with the fovea region, where visual perception is most sensitive, and gradually expands to the peripheral visual field. Each training phase uses the binocular balance point of the previous region as a benchmark to progressively improve binocular contrast balance and coordination. Simultaneously, an adaptive feedback mechanism is introduced to avoid the uneven results that may result from standardized training.

[0018] The present invention also discloses a binocular contrast balance training system for foveal and peripheral vision. Since it belongs to the same technical concept as the method and solves the same technical problem, it should have the same beneficial effect, and will not be described in detail here.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] The embodiments of this invention are written in a progressive manner.

[0023] This invention provides a method and system for training binocular contrast balance in the fovea and peripheral vision. It primarily addresses the technical problem that existing technologies have limitations in effectively intervening in the eye's retinal accommodation mechanism, particularly in the binocular visual integration ability of the peripheral vision.

[0024] like Figure 1 As shown, based on this, the present invention provides a method for training binocular contrast balance between the fovea and peripheral visual fields, comprising the following steps: S1. In the foveal region, set the initial contrast of the foveal region, and adjust the visual targets with the same phase multiple times through dynamic Gabor spot stimulation and user feedback information so that the two eyes are in a balanced state of phase, and obtain the first binocular contrast balance point. S2. In the inner circle region, the initial contrast of the inner circle region is set according to the first binocular contrast balance point. Based on the dynamic Gabor spot stimulation and user feedback information, the phase-same targets in multiple positions of the inner circle are adjusted multiple times to make the two eyes in a phase-same balance state, so as to obtain the second binocular contrast balance point and the contrast balance state of each position of the inner circle. S3. In the middle circle region, according to the second binocular contrast balance point and the contrast balance state of each direction in the inner circle, the binocular contrast is adaptively adjusted according to the first rule, and the initial contrast of the middle circle region is set. Based on the dynamic Gabor spot stimulation and user feedback information, the phase-opposite targets in multiple directions in the middle circle are adjusted multiple times to make the two eyes in a phase-opposite balance state, so as to obtain the third binocular contrast balance point and the contrast balance state of each direction in the middle circle. S4. In the outer ring region, according to the third binocular contrast balance point and the contrast balance state of each direction in the middle ring, the binocular contrast is adaptively adjusted according to the second rule, and the initial contrast of the outer ring region is set. Based on the dynamic Gabor spot stimulation and user feedback information, the phase-opposite targets in multiple directions of the outer ring are adjusted multiple times to make the two eyes in a phase-opposite balance state, so as to obtain the fourth binocular contrast balance point and the contrast balance state of each direction in the outer ring.

[0025] Dynamic Gabor spot stimulation is an amblyopia training method based on visual neuroplasticity. Its core principle is to activate visual cortical neurons and optimize neural pathway structure through dynamic visual stimulation of specific frequencies, directions, and contrasts. This technology can effectively improve the contrast sensitivity of amblyopic patients, enhance their ability to distinguish low-contrast objects, and thus improve overall visual function. User feedback refers to the questions posed to users by trainers during contrast balance training, and the answers obtained by users based on binocular visual perception. The fovea is the concave structure in the center of the macula of the retina, which is the area with the most acute vision. Optotypes are standardized test graphics used in ophthalmological examinations to assess visual acuity, refractive status, and visual function. Their design is based on the principle that the human eye can only resolve the smallest angle of view (1 minute angle of view). Different optotypes are used for targeted testing of specific visual functions. Phase refers to the core parameter describing the signal or vibration state in periodic phenomena, and its definition and application cover multiple fields such as physics, engineering, and neuroscience.

[0026] In steps S1 to S4, an initial contrast is set in the fovea region. Dynamic Gabor spot stimulation and user feedback are used to repeatedly adjust the phase-equal targets, achieving a phase-equal balance between the two eyes, thus obtaining the first binocular contrast balance point. Using this first point as a benchmark, phase-equal targets in multiple locations within the inner circle are further adjusted in the same manner to obtain the second point and contrast values ​​for each location within the inner circle. This process is repeated to obtain the third point and contrast balance for the middle circle region, and the fourth point and contrast balance for the outer circle region. The binocular contrast balance training method employs a progressive training design, starting from the most visually sensitive fovea region and gradually expanding to the peripheral visual field. Each training stage uses the binocular balance point of the previous region as a benchmark, gradually improving binocular contrast balance and coordination. This design ensures the scientific and rational nature of the training process, avoids overstimulation, and progressively improves visual integration ability, conforming to the natural laws of visual adaptation.

[0027] In one embodiment, this application is implemented as follows. In the foveal region, dynamic Gabor spot stimulation is used to adjust the contrast and find an initial balance point. This is typically adjusted in real time based on patient feedback until visual perception in both eyes is consistent. The visual targets are presented as binocular split images, with an initial binocular contrast of 50% for the poorer eye and 50% for the better eye. The visual targets viewed by the poorer and better eyes are continuously adjusted until a white line appears at the center of the visual target when the eyes integrate. The system records the contrast between the left and right eyes at this point as the binocular contrast balance point (e.g., 65% for the poorer eye and 35% for the better eye) and uses this balance point as the training benchmark. When the eyes achieve perceptual consistency in the foveal region, peripheral visual training begins. The balance point obtained from the first stage of foveal training is used, for example, 65% for the poorer eye and 35% for the better eye. The training process is the same as the foveal training process. Visual targets with the same phase are randomly presented in 12 directions within the inner circle. After the patient integrates their eyes, they report a balance state, and the system automatically records the contrast balance in that direction. The initial contrast of the middle circle is set based on the balance point of the inner circle. If the inner circle balance point is 65% for the poor eye and 35% for the good eye, then the contrast of the middle circle is adaptively adjusted based on the contrast balance of the inner circle. Opposite-phase targets are randomly presented in 12 locations within the middle circle; after binocular integration, the patient reports a balance state, and the system automatically records the contrast balance at that location. The contrast of the outer circle is usually higher than the foveal contrast, so the contrast is adaptively set according to the adaptive rules of the inner and middle circles. The training process involves randomly presenting opposite-phase targets in 12 locations within the outer circle; after binocular integration, the patient reports a balance state, and the system automatically records the contrast balance at that location. This ensures a smooth transition of visual balance between different visual areas.

[0028] Preferably, it further includes: Monitor the user's eye movement trajectory; The first step is to determine whether the user's eye movement trajectory matches the preset movement trajectory; If the first judgment result is negative, retraining is performed until the user's eye movement trajectory matches the preset movement trajectory.

[0029] The eye movement trajectory includes the following: horizontal movements: horizontal saccadic movements are achieved through the antagonistic action of the medial and lateral rectus muscles. Vertical movements: vertical eye movements are completed through the coordinated action of the superior and inferior rectus muscles. Rotational movements: the superior and inferior oblique muscles adjust the rotation of the eyeball around the visual axis.

[0030] The above steps involve tracking the user's eye movement trajectory with an eye tracker, determining whether the eye movement trajectory conforms to a preset trajectory, and retraining until the user's eye movement trajectory conforms to the preset trajectory when it does not conform.

[0031] In one embodiment, this application is implemented as follows: The training process incorporates eye-tracking to monitor eye movements. If the eye movements do not meet the system's set criteria, a second training session is required at the same location until the eye movements meet the criteria before proceeding to the next step. A precise visual feedback mechanism ensures that the patient continuously focuses on the center of the screen, preventing eye movement deviation from affecting the training results.

[0032] like Figure 2 As shown, preferably, after first determining whether the user's eye movement trajectory conforms to a preset movement trajectory, the method further includes: A1. Divided into four quadrants based on the user's field of vision; A2. Using the spatial position of the outermost viewpoint in each quadrant as a reference, obtain the vertical pixel distance between the spatial position of the outermost viewpoint in each quadrant and the preset central concave point, and set the deviation range reference based on the vertical pixel distance; A3. If the first judgment result is negative, the second judgment is whether the user's eye movement trajectory is greater than the deviation range benchmark. If so, it is defined as abnormal user eye movement deviation. A4. Third, determine whether the user feedback information is correct; A5. If so, retrain until the user's eye movement trajectory matches the preset movement trajectory.

[0033] Quadrants are important tools in mathematics and science used for classifying and analyzing data. They are divided into four regions by the Cartesian coordinate system, in counter-clockwise order: Quadrant I (x>0, y>0), Quadrant II (x<0, y>0), Quadrant III (x<0, y<0), and Quadrant IV (x>0, y<0). The coordinate axes and the origin do not belong to any quadrant. In the complex plane, quadrants represent the phase angle range of complex numbers; vertical pixel distance refers to the pixel difference between two points in an image or display device in the vertical direction.

[0034] Steps A1 to A5 are the specific implementation details after the first judgment. They involve virtually dividing the user's field of vision into four quadrants, obtaining the spatial position of the visual target in each quadrant, and using the spatial position of the outermost visual target as a reference to calculate the vertical pixel distance between the spatial position of the outermost visual target in each quadrant and the preset central concave point. A deviation range reference is set based on this vertical pixel distance. If the first judgment result is negative, i.e., the user's eye movement trajectory does not conform to the preset movement trajectory, a second judgment is made to determine whether the user's eye movement trajectory is greater than the deviation range reference. If it is, it is defined as an abnormal user eye movement deviation. After the second judgment, a third judgment is made to determine whether the user's feedback information is correct. If it is, retraining is performed until the user's eye movement trajectory conforms to the preset movement trajectory.

[0035] In one embodiment, this application is implemented as follows: The visual field is virtually divided into four quadrants, and the position and number of visual targets within each quadrant are randomly distributed. To detect eye movement, the system uses the position of the outermost visual target in each quadrant as a reference, and the vertical pixel distance between this visual target and the fovea as the maximum allowable range. The maximum allowable eye movement range within each quadrant is set to 1 / 3 of the vertical distance between the outermost region of each visual field and the center point. During training, if the eye movement exceeds the vertical pixel distance between the reference visual target and the fovea when the eye moves to the first quadrant, it is considered an abnormal eye movement. If the user can still answer the question correctly under these circumstances, training needs to be repeated at the current location until the user's eye movement conforms to the specified range; if the answer is incorrect, training is allowed to continue. The system does not intervene when the eye moves to the second, third, or fourth quadrants, and this does not affect the training process.

[0036] like Figure 3 As shown, preferably, by repeatedly adjusting the visual targets with the same phase through dynamic Gabor spot stimulation and user feedback information, so that the two eyes are in a balanced state of phase equality, the first binocular contrast balance point is obtained, including the following steps: B1. Based on the initial contrast of the foveal region, the same phase targets are adjusted multiple times according to the preset rule of increasing the contrast of abnormal eyes and simultaneously decreasing the contrast of normal eyes through dynamic Gabor spot stimulation and user feedback information. B2. When both eyes are integrated, the center of the visual target appears as a white line, which is defined as a state of phase balance between the two eyes. B3. Under the condition of equal phase balance in both eyes, obtain the contrast of the normal eye and the contrast of the abnormal eye as the first binocular contrast balance point.

[0037] Steps B1 to B3 are the specific implementation details of step S1. After setting the initial contrast of the inner circle region based on the first binocular contrast balance point, the initial contrast of the fovea region is used as a reference. Through dynamic Gabor spot stimulation and user feedback information, the phase-equivalent targets are adjusted multiple times according to the preset rule of increasing the contrast of the abnormal eye and simultaneously decreasing the contrast of the normal eye. When the two eyes are integrated, a white line appears in the center of the target, which indicates that the two eyes are in a phase-equivalent balance state. In this state, the contrast of the normal eye and the abnormal eye is obtained as the first binocular contrast balance point.

[0038] In one embodiment, this application is implemented as follows. In the foveal region, dynamic Gabor spot stimulation is used to adjust contrast, finding an initial equilibrium point. This is typically adjusted in real-time based on patient feedback until visual perception in both eyes is consistent. The optotype is presented as a binocular split image, with an initial binocular contrast of 50% for the poorer eye and 50% for the better eye. The user wears polarized glasses for training. During this stage, based on whether a white line appears at the center of the optotype, the user manually adjusts the optotype viewed by the poorer and better eyes using the mouse. The adjustment criterion is to increase the contrast of the poorer eye and decrease the contrast of the better eye. This adjustment is continuously performed until a white line appears at the center of the optotype when both eyes are integrated. The system records the left and right eye contrast at this point as the first binocular contrast equilibrium point (e.g., 65% for the poorer eye and 35% for the better eye), and uses this equilibrium point as the training benchmark.

[0039] like Figure 4 As shown, preferably, the phase-equivalent targets at multiple locations within the inner circle are adjusted multiple times based on dynamic Gabor spot stimulation and user feedback information to achieve a phase-equivalent balance state for both eyes, thereby obtaining the second binocular contrast balance point and the contrast balance state at each location within the inner circle. This includes the following steps: C1. Based on the initial contrast of the inner circle region, the phase-same targets in multiple positions of the inner circle are adjusted multiple times according to the preset rule of increasing the contrast of abnormal eyes and simultaneously reducing the contrast of normal eyes through dynamic Gabor spot stimulation and user feedback information. C2. When both eyes are integrated, the center of the visual target appears as a white line, which is defined as a state of phase balance between the two eyes. C3. Under the condition of equal phase balance in both eyes, obtain the contrast of the normal eye and the contrast of the abnormal eye as the second binocular contrast balance point; C4. Fourth, determine whether the user feedback information is correct; C5. Obtain the contrast balance state of each position in the inner circle based on the fourth judgment result.

[0040] Steps C1 to C5 are the specific implementation details of step S2. After setting the initial contrast of the inner circle region through the first binocular contrast balance point, the second binocular contrast balance point of the inner circle region is obtained by training according to the training process of steps B1 to B3, and the contrast balance state of each position of the inner circle is obtained accordingly.

[0041] In one embodiment, this application is implemented as follows. The balance point obtained from the first stage of foveal training is used; for example, 65% for the poor eye and 35% for the good eye, and the training process is consistent with the foveal training process. Visual targets with the same phase are randomly presented in 12 directions within the inner circle. After the patient integrates their binoculars, they report the balance state, and the system automatically records the contrast balance in that direction.

[0042] like Figure 5 As shown, preferably, in the middle circle region, the binocular contrast is adaptively adjusted according to the first rule based on the second binocular contrast balance point and the contrast balance state of each direction in the inner circle, and the initial contrast of the middle circle region is set, including the following steps: D11. If the fourth judgment result is yes, define the target with the same phase on the corresponding inner circle azimuth as the first target; D12. If the first judgment result is negative, the corresponding inner circle azimuth with the same phase is defined as the second azimuth; D21. Based on the initial contrast of the inner circle region, the first visual target is adjusted by dynamically stimulating Gabor spots and using user feedback information to increase the contrast of the abnormal eye while simultaneously decreasing the contrast of the normal eye, with the adjustment range being N. D22. Based on the initial contrast of the inner circle region, the second visual target is adjusted according to the preset rule of increasing the contrast of the abnormal eye and simultaneously decreasing the contrast of the normal eye with an adjustment range of 2N, through dynamic Gabor spot stimulation and user feedback information. D3. Based on the adjusted first and second visual targets, set the initial contrast of the center circle area.

[0043] Steps D11 to D3 are the specific implementation details of the adaptive adjustment and setting of the initial contrast of the middle circle region in step S3. They involve defining the first visual target as the one with the same phase in the inner circle corresponding to correct user feedback, and defining the second visual target as the one with the same phase in the inner circle corresponding to incorrect user feedback. Based on the initial contrast of the inner circle region, the first visual target is adjusted using a preset rule that dynamically increases the contrast of the abnormal eye and simultaneously decreases the contrast of the normal eye, with the adjustment range limited to N, based on dynamic Gabor spot stimulation and user feedback. The second visual target is adjusted in the same way but with the adjustment range limited to 2N. The initial contrast of the middle circle region is then set based on the adjusted first and second visual targets.

[0044] In one embodiment, this application is implemented as follows: The contrast of the middle circle is adaptively adjusted according to the contrast balance of the inner circle: within the middle circle, for the position corresponding to an incorrect answer in the inner circle, the contrast of the poor eye is 75%, and the contrast of the good eye is 25%; for the position corresponding to a correct answer in the inner circle, the contrast of the poor eye is 70%, and the contrast of the good eye is 30%.
