Abstract
Description
Technical Field
[0001] This application relates to the field of vision training technology, and in particular to a vision training method, apparatus and device based on dynamic field of view. Background Technology
[0002] Eye fusion and accommodation / convergence training are important training methods specifically targeting the visual system, offering significant benefits and implications for eye health. Eye fusion training, through a series of visual activities, enhances binocular coordination, improving the eyes' ability to fuse different images into a single stereoscopic image. This helps eliminate visual inhibition, expands the fusion range, enhances stereoscopic vision, and provides adjunctive treatment for visual problems such as strabismus and amblyopia. Eye accommodation / convergence training, by exercising the eyes' accommodation and convergence functions, improves the speed and accuracy of the eyes adapting to objects at different distances, enhances convergence response, and improves visual perception efficiency, helping to prevent the occurrence and development of vision problems such as myopia. Both eye fusion and accommodation / convergence training not only help improve existing visual problems but also enhance the eyes' adaptability and overall visual quality, playing a crucial role in protecting eye health. However, current eye fusion and accommodation / convergence training methods are based on a single two-dimensional plane, failing to fully consider the interaction between spatial changes and the eye fusion and accommodation / convergence systems, resulting in poor visual training effects.
[0003] Currently, there are various training devices on the market based on technologies such as naked-eye 3D, red-green (blue) beam splitting, polarized beam splitting, and virtual reality (VR) for eye fusion and accommodation / convergence. These devices generally achieve the training effect by processing stereoscopic image pairs on a two-dimensional plane to create binocular disparity and generate a sense of depth. The main mechanisms of these training devices include: binocular disparity principle, fusion mechanism, and accommodation / convergence mechanism. The binocular disparity principle refers to these devices presenting slightly different images to the left and right eyes, simulating the situation in the real world where both eyes view the same object from different angles; this difference is interpreted by the brain as depth information, thus forming a sense of depth. The fusion mechanism refers to the merging of the images received by both eyes into a clear stereoscopic image in the brain; this process depends on the eye's fusion ability; training devices promote this ability by providing accurate binocular disparity images. The accommodation / convergence mechanism refers to the need for the eyes to constantly adjust focus (accommodation) and line-of-sight angle (convergence) to maintain binocular single vision.
[0004] The training devices described above simulate the convergence and divergence requirements of the eyes under different fixation states by presenting stereoscopic images with different parallax gradients on the same plane, and the corresponding accommodative responses triggered when convergence and divergence occur, thereby training binocular fusion and accommodative convergence and divergence abilities. The actual training process using these devices typically includes a preparation phase, a training phase, and a conclusion phase.
[0005] The preparation stage begins with selecting the equipment: based on individual circumstances and training needs, choose suitable training equipment, such as a naked-eye 3D vision trainer, a red-green (blue) beam splitter, a polarization beam splitter, or VR training equipment. Next, adjust the equipment: ensure the training equipment is in the correct position and angle so that both eyes can comfortably receive the image; for VR equipment, the tightness and focus of the headset also need to be adjusted to ensure image clarity.
[0006] During the training phase, naked-eye 3D devices using AI pupil tracking technology can be employed, allowing each eye to see two different images. The brain then constructs a virtual three-dimensional image based on the visual information. The eyes then need to track the images in all directions to achieve visual training. Alternatively, red-green (blue) beam splitters can be used with red-green (blue) glasses. By adjusting the position and angle of the red-green (blue) images, visual training can be performed. Polarized beam splitters use polarized lenses to allow each eye to see polarized light images at different angles. These images are then fused to achieve the training objective. VR devices can also be used to enter virtual scenes, training the eyes' fusion and accommodation / convergence abilities by focusing on and tracking virtual objects. As training progresses, the difficulty is gradually increased, such as by increasing image complexity and improving the speed of fixation and tracking, to comprehensively train the eyes' fusion and accommodation / convergence abilities.
[0007] The final stage refers to the end of training. The training effect is evaluated by comparing individual results with historical training data, with a focus on assessing improvements in the eye's fusion and accommodative convergence abilities. Based on this evaluation, subsequent training plans are adjusted according to individual circumstances. Summary of the Invention

This dynamic field-of-view-based visual training method can more realistically simulate visual changes in daily life, allowing the eyes to "truly move" during training, thereby significantly improving the training effect of eye fusion and accommodation / convergence functions.
[0105] It should be noted that this dynamic field-of-view-based visual training method combines near-field devices, far-field devices, and flickering vision enhancers (such as red-green / red-blue spectacle glasses) to simulate visual scenes in real-world environments, making the training process more closely resemble actual eye needs. This natural training method not only increases user engagement but also reduces discomfort during training and enhances the sustainability of training.
[0106] This application provides a visual training method based on dynamic field of view, comprising: acquiring detection data and a training duration threshold for the user to be trained; the detection data including far-distance data, near-distance data, and measurement accuracy; conducting tests on the user to be trained based on the detection data to obtain pre-training visual acuity data; determining training data based on the visual acuity data; and performing alternating cyclic training of the user to be trained in far-field and near-field according to the training data until the training duration threshold is reached, thus completing the visual training for the user to be trained. This visual training method based on dynamic field of view first acquires the visual acuity data detected by the user to be trained to determine the training data, and then performs alternating cyclic training of the user to be trained in far-field and near-field according to the training data and the training duration threshold. This allows the user's eyes to "truly move" during the training process, thereby significantly improving the training effect of eye fusion and accommodation convergence functions. It solves the technical problem that existing eye fusion and accommodation convergence function training methods are based on a single two-dimensional plane and do not fully consider the linkage between spatial changes and the eye fusion and accommodation convergence systems, resulting in poor visual acuity training effects.
[0107] In one embodiment of this application, determining training data based on vision data includes:
[0108] The number of farsightedness targets for the training data is calculated based on the distance vision data; the number of nearsightedness targets for the training data is calculated based on the near vision data.
[0109] The far-set separation distance of the training data is calculated based on the far-set fusion separation distance; the far-spread separation distance of the training data is calculated based on the far-set fusion separation distance; and the far-set fusion duration of the training data is calculated based on the far-set fusion duration and the near-set fusion duration.
[0110] The near-convergence separation distance of the training data is calculated based on the near-convergence divergence separation distance; the near-convergence duration of the training data is calculated based on the near-convergence fusion required duration;
[0111] Among them, the far convergence separation distance is not greater than the far-distance fusional convergence separation distance, the far divergence separation distance is not greater than the far-distance fusional divergence separation distance, the far fusional duration is not less than 5 times the near fusional duration, the near convergence separation distance is not greater than the near fusional convergence separation distance, the near divergence separation distance is not greater than the near fusional divergence separation distance, and the near fusional duration is not less than 2 times the near fusional duration required.
[0112] It should be noted that this dynamic field-of-view-based visual training method determines training data based on visual acuity data before conducting visual training on the users to be trained. In determining the training data, one step is to set the optotype size: the farsighted optotype pole number E is set. y0 =E y / 2, setting the myopia target level size E j0 =E j / 2. The higher the optotype level, the greater the training difficulty. The maximum optotype level for training should be ≤ the optimal visual acuity level, such as: E. y0 ≦E y E j0 ≦E j Second, set the far / near fusion separation distance: far fusion separation distance Y j0 =50%Y j Dispersion distance Y s0 =50%Y s Near set separation distance J j0 =50%J j Nearly dispersed separation distance J s0 =50%J s The larger the separation distance, the greater the training difficulty; the maximum limiting factor is the far set separation distance Y. j0≦Y j The maximum divergence separation distance Y s0 ≦Y s The largest near set separation distance J j0 ≦J j The maximum near-dispersion separation distance is J s0 ≦J s Third, set the training duration and the far / near fusion switching time; the default training duration is 5 minutes, and the training time threshold X is limited. t ≥5 minutes; Duration of far-field fusion imaging Y t0 =max(1000%Y t 1000%J t ), duration of near-fusion imaging J t0 =200%J t Limit the shortest possible duration of near-fusion imaging J t0 ≥200%J t And Y t0 ≧5*J t0 .
[0113] Figure 3 This is a flowchart illustrating the framework of iterative training in the visual training method based on dynamic field of view described in the embodiments of this application.
[0114] like Figure 3 As shown, in one embodiment of this application, the visual training of the user to be trained is performed by alternating between far field of vision and near field of vision based on training data until the training duration reaches a training duration threshold, thereby completing the visual training of the user to be trained.
[0115] The operation of the far field of view equipment is controlled according to the far field of view pole number and the duration of far fusion to conduct far field of view training, and the first total training duration at this time is obtained.
[0116] If the first total training time is less than the training time threshold, the operation of the myopia field device is controlled according to the myopia target pole number and the duration of myopia fusion to carry out myopia field training, and the second total training time at this time is obtained.
[0117] If the total training time is less than the training time threshold, return to the step of controlling the operation of the far field of vision device according to the far field of vision pole number and the duration of far fusion to carry out far field of vision training, and then perform far field of vision training and near field of vision training in a loop until the total training time reaches the training time threshold, and complete the visual training of the user to be trained.
[0118] If the first total training time or the second total training time is not less than the training time threshold, the visual training of the user to be trained is completed.
[0119] The training for the far field of view includes: gradually increasing the red-green target separation distance of the far field of view device from 0cm to the far convergence separation distance, then gradually changing from the far convergence separation distance to the far divergence separation distance, and then gradually changing from the far divergence separation distance to the far convergence separation distance, and so on until the duration of operation of the far field of view device reaches the duration of far fusion, and then controlling the far field of view device to be turned off;
[0120] The training content for the myopia field includes: gradually increasing the red-green target separation distance of the myopia field device from 0cm to the near convergence separation distance, then gradually changing the near convergence separation distance to the near divergence separation distance, and then gradually changing the near divergence separation distance back to the near convergence distance. This cycle continues until the duration of operation of the myopia field device reaches the near fusion duration, at which point the myopia field device is turned off.
[0121] It should be noted that during the alternating training of the far-field and near-field devices for the user to be trained based on training data and training duration thresholds, the user is first trained in the far-field mode. The screen of the near-field device is turned off, the screen of the far-field device is turned on, and the user is prompted to carefully observe the screen of the far-field device. The separation distance between the red and green visual targets on the far-field device gradually changes from 0cm to Y. j0 Then Y j0 Stepwise transformation to Y s0 Then Y s0 Then gradually transform to Y j0 This cycle continues until the duration reaches the far-field fusion imaging duration Y. t0 When the total training time is less than the training time threshold, the screen of the far-field device is turned off, the screen of the near-field device is turned on, and the user is prompted to carefully observe the screen of the near-field device. The separation distance between the red and green targets of the near-field device gradually changes from 0 cm to J. j0 Then J j0 Stepwise transformation to J s0 Then J s0 Then gradually transform to J j0 This cycle continues until the duration reaches J. t0 If the total training time is less than the training time threshold, switch back to far field of view training and repeat the far and near field of view training until the total training time reaches the set training time threshold X. t This concludes the visual training for the user.

Figure 5 This is a flowchart illustrating the duration detection framework in the dynamic field-of-view-based visual training method described in this application embodiment.
[0123] like Figure 4 and Figure 5 As shown, in one embodiment of this application, the vision data of the user to be trained is obtained by testing based on the detection data, including:
[0124] Visual acuity data for the trainee was obtained by using a visual acuity chart with the optotypes on the chart from largest to smallest, and by using a visual acuity chart with the optotypes on the chart from largest to smallest.
[0125] Using a far-field-of-view device, the beam-splitter is used to test the fusion convergence capability of the user to be trained according to the fusion convergence rule, and the far-distance fusion convergence separation distance is obtained; using a far-field-of-view device, the beam-splitter is used to test the fusion divergence capability of the user to be trained according to the fusion divergence rule, and the far-distance fusion divergence separation distance is obtained.
[0126] Using a myopic field device, the spectroscopic target is used to test the fusion convergence ability of the user to be trained according to the fusion convergence rule, and the near-range fusion convergence separation distance is obtained; using a myopic field device, the spectroscopic target is used to test the fusion divergence ability of the user to be trained according to the fusion divergence rule, and the near-range fusion divergence separation distance is obtained.
[0127] The duration of the training user was measured using a far-field-of-view device according to the far-field fusion duration rule to obtain the required duration of far-field fusion; the duration of the training user was measured using a near-field-of-view device according to the near-field fusion duration rule to obtain the required duration of near-field fusion.
[0128] It should be noted that the visual acuity data for visual training is obtained by testing the users to be trained based on the test data. In this embodiment, during the visual acuity test of the users to be trained, the distance visual acuity test is performed by activating the screen of the distance vision device to display a standard distance visual acuity chart (such as a logarithmic visual acuity chart or a children's special graphic visual acuity chart, which can be switched as needed). The optotypes (such as letters, numbers, or graphics) on the visual acuity chart are displayed in descending order of size. The users to be trained identify and report the content of the optotypes they see line by line according to the optotypes on the screen. The distance visual acuity value (such as 5.0, 4.9, etc.) corresponding to the smallest number of optotype lines that the users to be trained can clearly identify is recorded as distance visual acuity data, and the distance visual acuity data is also saved to the user's profile. Near vision testing involves activating the near vision field device and displaying a standard near vision chart (such as the Jaeger or LogMAR near vision chart, which can be switched as needed). The optotypes (such as letters, numbers, or graphics) on the chart are displayed sequentially from largest to smallest. The user to be trained identifies and reports the content of the optotypes seen on the screen line by line. The near vision value corresponding to the smallest number of optotype lines that the user can clearly identify is recorded as near vision data and saved to the user's profile.

[0130] It should be noted that during the testing of far-field fusional convergence ability, red-green (blue) spectroscopic targets (target level = best distance visual acuity level / 2) are displayed on the screen of the far-field device. The user to be trained is asked to look at the screen of the far-field device and whether they see a single, clear image. The horizontal separation distance of the red and green targets is gradually increased towards the inner (nasal) side of the eye, according to the step size of each far-field movement (using binocular convergence ability). When the user sees the targets as split or blurred, the separation distance is recorded. This process is repeated three times, and the average of the three separation distances is taken as the far-field fusional convergence separation distance Y. j Calculate the long-distance fusion ensemble capability (Δ) = Y j / Y. During the testing of far-field fusional divergence ability, red-green (blue) spectroscopic targets (target level = best distance visual acuity level / 2) are displayed on the screen of the far-field device; the user to be trained is asked to look at the screen of the far-field device and whether they see a single, clear image; the horizontal separation distance of the red and green targets is gradually increased outwards with each step of far-field movement (using binocular divergence ability); when the target seen by the user is split or blurred, the separation distance is recorded, and this is repeated three times. The average of the three separation distances is taken as the far-field fusional divergence separation distance Y. s Calculate the long-distance fusion divergence capability (Δ) = Y s / Y. During the near-field fusional convergence test, red-green (blue) spectroscopic targets (target level = best near visual acuity level / 2) are displayed on the screen of the near-field device. The user to be trained is asked to look at the screen of the near-field device and whether they see a single, clear image. The horizontal separation distance of the red and green targets is gradually increased towards the inner eye (nasal side) according to the near-field movement step (using binocular convergence ability). When the user sees the targets as split or blurred, the separation distance is recorded. This is repeated three times, and the average of the three separation distances is taken as the near-field fusional convergence separation distance J. jCalculate the near-range fusion convergence capability (Δ) = J j / J.

The average of the three separation distances is taken as the near-field fusional divergence separation distance J. s Calculate the near-range fusion divergence capability (Δ) = J s / J.

[0133] It should be noted that during the detection of the distance fusion duration, the screen of the near-field device is turned off, and the screen of the far-field device is turned on. The user is prompted to carefully observe the screen of the far-field device, and the distance separation distance is taken as Y. j 50%Yj Y s 50%Y s Five sets of red-green (blue) visual targets (0 and 0) are used as distance fusion time detection data. After binocular fusion is performed on the user, the five sets of red-green (blue) visual targets are presented from far to near. The positions of the five sets of red-green (blue) visual targets are randomly shuffled to generate distance target position data. The user is then asked to arrange the visual targets in order from far to near according to their perceived positions. The time required for the user to correctly complete the arrangement of all visual targets is recorded. This process is repeated three times, and the average of the three times is taken as the distance fusion time Y. t During the near-field fusion duration detection, the screen of the far-field device is turned off, and the screen of the near-field device is turned on.

[0160] Example 3:
[0161] Figure 7 This is a schematic diagram of the visual training system based on dynamic field of view described in an embodiment of this application.
[0162] like Figure 7 As shown, this application provides a vision training system based on dynamic field of view, including a dynamic field of view training unit and a far field of view device and a near field of view device connected to the dynamic field of view training unit. The far field of view device and the near field of view device are respectively connected to a flicker vision enhancer. The dynamic field of view training unit controls the operation of the far field of view device and the near field of view device according to the above-described vision training method based on dynamic field of view, so as to complete the vision training for the user to be trained.
[0163] It should be noted that the visual training method based on dynamic field of view has already been described in Embodiment 1, and will not be repeated in this embodiment. The flickering vision enhancer can be red-green (blue) spectacle glasses.
[0164] In the embodiments of this application, before testing the user to be trained based on the detection data and obtaining the vision data before training, the vision training method based on dynamic field of view includes adjusting the far field of view device, the near field of view device and the red-green (blue) spectrophotometer.
[0165] It should be noted that the debugging process includes: 1. Checking whether the near-field device, far-field device, and red-green (blue) spectrophotometer are working properly; 2. Correcting the brightness, contrast, and other parameters of the near-field and far-field devices to ensure clear display; 3. Confirming that the dynamic field-of-view training unit has been started and checking whether its program functions are normal; 4. Initializing the dynamic field-of-view training unit program to ensure that the position of the red-green (blue) optotypes displayed on the screen is consistent with the position of the red-green (blue) spectrophotometer (i.e., assuming the right eye has a red spectrophotometer, the red optotype is located on the right side of the screen, and the green (blue) optotype is located on the left side of the screen); 5. The dynamic field-of-view training unit program automatically obtains the dpi and resolution of the near / far-field devices and converts the pixel unit to centimeters. (Assuming screen resolution = W * H pixels and screen DPI = dpi, then the horizontal width of the screen Wcm = (W / dpi) * 2.54 cm; the vertical width of the screen Hcm = (H / dpi) * 2.54 cm).

The contents of the core training functions, user role management, system management, data analysis and reporting, security and privacy, and extended functions are shown in Table 1.
[0169] Table 1 shows the functional modules of the dynamic field-of-view training unit.
[0170]
[0171] In this embodiment, the dynamic field-of-view-based visual training system can automatically generate personalized training plans based on the user's visual acuity and training progress, and provide real-time feedback and adjustment suggestions. This personalized training method can better meet the needs of different users and help them achieve their training goals more quickly. This dynamic field-of-view-based visual training system significantly improves the effectiveness of visual training and the user experience, while also considering safety and universality, and has significant practical value and social significance.
