These methods lack systematicity and scientificity, and the training effect is not obvious and difficult to last. Although existing vision training equipment can provide some visual stimulation to a certain extent, it generally has problems such as single function, fixed training mode, and lack of personalized customization. For example, some equipment can only perform simple near and far adjustment training, and cannot accurately design training programs according to the vision conditions and training needs of different users; during the training process, it is impossible to monitor and adjust the training parameters in real time, resulting in uneven training effects; and the control of visual contrast is not precise enough to effectively prevent excessive growth of the eye axis, making it difficult to effectively prevent the development of myopia.

[0064] During the training process, the data storage and analysis module records the user's training data in real time, including training time, training mode, eye adjustment times and other information. After the training is completed, the data is analyzed to generate a training effect evaluation report;

[0065] S5. Safety protection and reminders:

[0066] The protection and safety module works continuously during the training process, monitoring the device temperature. When the temperature is too high, it automatically reduces the device power or issues an alarm to remind the user. At the same time, it checks whether the user is using the device correctly.

[0067] S6. End of training:

[0068] When the training time reaches the set value, the device stops running and the display shows the training end interface. The user can view the detailed data and effect evaluation report of this training.

[0069] The specific steps are as follows:

[0070] (1) Composition and structure of the visual training instrument:

[0071] 1. Host and core component modules:

[0072] This module is the core control part of the visual training instrument, which contains hardware for processing visual signals, such as advanced microprocessors and image processing chips. These hardware can quickly and accurately process and convert visual signals to ensure the smoothness and stability of the flip image changes and the operation of the LED sight mark. For example, when processing high-frequency flip image switching, the microprocessor can quickly calculate and output the corresponding control signal to ensure the timeliness and accuracy of image switching, providing users with a stable visual training environment.

[0073] The operation panel is designed to be concise and clear. Users can easily set parameters such as training mode and time through intuitive buttons or sensitive touch functions. For example, users can easily select different training modes on the operation panel, such as the mode for eye adjustment ability training, the mode for preventing myopia, etc., and set the training time according to their own situation, such as 15 minutes, 30 minutes or 60 minutes, etc.;

[0074] The adjustable bracket is made of strong and flexible materials, which is convenient for users to adjust the height and angle of the device. Whether sitting on a chair or standing to use the visual trainer, users can adjust the bracket to accurately adjust the device to a position where the eyes can comfortably and accurately align with the sight mark, ensuring the effectiveness of the training effect.

[0075] 2. LED sight mark and aperture module:

[0076] LED sight marks use high-brightness, low-power LED lamp beads, which can emit stable and clear light to provide users with clear visual targets. During the training process, the brightness of the sight mark can be adjusted according to the user's needs and training stage. For example, in the initial training stage, the user can brighten the sight mark to better adapt to the training; as the training progresses, the brightness can be gradually reduced to increase the difficulty of training and further improve the eye's adjustment ability;

[0077] The aperture illumination zone is located within the range of 10-60 degrees outside the sight mark. Through the carefully designed optical structure and control system, the contrast of the visual area can be effectively reduced. In actual applications, when the user looks at the sight mark, the existence of the aperture illumination zone can reduce the high-intensity stimulation of the retina and help prevent excessive growth of the eye axis. At the same time, it improves the user's attention during training, allowing them to focus more on the sight mark and improve training accuracy.

[0078] 3. Power system module:

[0079] Adopt DC6V low-voltage DC power supply. This power supply mode ensures the stability and safety of the equipment during operation. Compared with high-voltage power supply, low-voltage power supply greatly reduces the electromagnetic interference generated during the operation of the equipment, reduces the impact on other electronic equipment, and also improves the adaptability of the equipment in different environments. It can be used normally in various places such as home, school, office, etc., and complies with the international medical equipment electrical safety standard "YY0505-2012 Medical Electrical Equipment", providing users with reliable safety protection;

[0080] The power system module is also equipped with a power management circuit, which can monitor the power status in real time and stabilize the voltage output. When the power voltage fluctuates, the power management circuit can be adjusted in time to ensure that each module of the device can obtain a stable power supply and prevent abnormal conditions such as overvoltage and overcurrent from causing damage to the equipment. At the same time, it has a battery power detection function. When the power is too low, the device will promptly prompt the user through the display or sound to charge or replace the power supply to ensure the continuity of the training process.

[0081] 4. Display screen and control panel module:

[0082] The LCD screen uses high-resolution and high-contrast screen technology, which can clearly and accurately display the training status, time, distance information of the sight mark, etc. During the training process, the user can monitor the training progress in real time through the display screen, such as the training time, remaining training time, current training mode and other information, which is convenient for the user to arrange the training process reasonably. For example, when conducting time-limited training, the user can check the remaining time at any time and adjust the training rhythm;

[0083] The buttons or touch functions on the control panel have good tactile feedback. Users can clearly feel the button presses or touch responses, making it convenient for users to perform various operations, such as easily setting training modes, accurately adjusting sight mark distances, or controlling LED brightness. In addition, the control panel also has an operation lock function. When users accidentally touch the control panel during training, it will not cause misoperation, ensuring the normal progress of training.

[0084] 5. Optical adjustment module:

[0085] The wavelength range of the LED sight mark is controlled between 460-700nm through precise optical filters and adjustment devices. The optical filter can filter out light in a specific wavelength range, and the adjustment device can fine-tune the wavelength according to the user's needs and training stage. Light of different wavelengths has different stimulation and training effects on the eyes. For example, in some training modes, you may need to use light with a longer wavelength to relax your eyes, while in other modes, you may need light with a shorter wavelength to enhance the eye's adjustment ability. By precisely controlling the wavelength range, the optical adjustment module can meet the differences in light sensitivity of different users and the diverse needs of different training stages.

[0086] 6. Training mode control module:

[0087] It has a variety of preset training modes, such as the basic adjustment training mode, which mainly trains the basic adjustment function of the eyes. Through simple flip-shot image switching and sight mark changes, it helps users become familiar with and adapt to the training process; the advanced visual response training mode increases the speed of image switching and the complexity of sight mark changes, improving the user's visual response speed and eye coordination ability; the myopia prevention and control training mode, combined with special optical parameter settings and training rhythm, focuses on preventing and slowing the development of myopia;

[0088] The personalized customized training mode allows users to freely set training parameters according to their own vision conditions, training goals and usage habits. Users can adjust the flip shot switching speed, such as starting from a slower speed and gradually increasing the switching speed to adapt to the improvement of the eye's adjustment ability; set the sight mark display time, and determine the appropriate sight mark display time according to their own concentration and reaction speed; adjust the training interval time, and reasonably arrange the rhythm of training and rest to make the training process more in line with personal needs and improve the effectiveness and comfort of training.

[0089] 7. Data storage and analysis module:

[0090] It can store a large amount of training data of users, including the time of each training, the selected training mode, the number of eye adjustments during training, gaze stability and other detailed information. These data are safely stored in the storage medium inside the device, such as flash memory chips. After the training, the data storage and analysis module will conduct an in-depth analysis of these data and use advanced algorithms to generate a training effect evaluation report. For example, by comparing data from different training stages, it analyzes indicators such as the improvement in the user's eye adjustment flexibility and the degree of improvement in gaze, and provides users with personalized improvement suggestions based on the analysis results, such as whether it is necessary to adjust the training mode, increase the training intensity or extend the training time, etc., to help users better train their vision.

[0091] 8. Protection and safety module:

[0092] The user's safety is fully taken into consideration during the design and manufacturing process of the equipment. An anti-glare design is adopted, and special optical coatings or structures are used to reduce the reflection and scattering of light to prevent damage to the eyes caused by strong light. Especially during long-term training, the user's eyes are protected from unnecessary stimulation. The device casing is made of safe materials, such as non-toxic, odorless, and impact-resistant plastic materials, to prevent users from being injured by contact with the device during use. At the same time, the design of the casing conforms to ergonomic principles, making it convenient for users to operate and hold the device.

[0093] The following is the specific use of the visual training instrument

[0094] Step 1: Equipment preparation and initialization

[0095] The user should first place the visual trainer on a stable desktop or a special bracket to ensure that the device does not shake or tilt to avoid affecting the training effect. Then, turn on the power and the device will automatically start the self-test program. During the self-test, the host and core component modules will check whether the internal hardware is working properly, such as whether the microprocessor, image processing chip, etc. can operate normally. The LED sight mark and aperture module will detect whether the LED sight mark is emitting light normally and whether the brightness adjustment of the aperture illumination area is normal. The power system module will check whether the power supply is stable and the battery power is sufficient. The display and control panel module will test whether the display is displaying normally and whether the buttons or touch functions are sensitive. After the self-test is completed, if all modules are working properly, the device will enter the standby state, and the display will show the initial interface, prompting the user to start parameter setting.

[0096] Step 2: User parameter settings

[0097] Users can set training parameters through the display screen and control panel module according to their own vision conditions, training goals and usage habits. During the operation, users can select different training modes by touching the screen or pressing buttons, such as basic adjustment training mode, advanced visual response training mode or myopia prevention and control training mode. For training time, users can choose the appropriate duration according to their schedule and eye fatigue, such as 15 minutes, 30 minutes or 60 minutes. At the same time, they can also adjust the sight mark distance as needed. For example, when the user feels that the eyes are tired, the sight mark distance can be adjusted farther to reduce the eye's adjustment burden; when you want to increase the difficulty of training, you can appropriately shorten the sight mark distance. In addition, users can also adjust the brightness and wavelength range of the LED sight mark according to their personal feelings to achieve the best training comfort and effect.

[0098] Step 3: Start training

[0099] After the user completes the parameter setting, press the start training button. After receiving the command, the host and core component modules immediately start the flip shot image change and LED sight mark operation. During the training process, the optical adjustment module controls the wavelength range of the LED sight mark in real time between 460-700nm according to the parameters set by the user to ensure that the wavelength of the light meets the training requirements. The LED sight mark and the aperture module form an aperture illumination area of ​​10-60 degrees outside the sight mark, effectively reducing the contrast of the visual area and reducing the high-intensity stimulation of the retina. The user's eyes look at the LED sight mark and follow the rapid image switching of the flip shot for adjustment training. The ciliary muscles of the eyes constantly switch between relaxation and tension, thereby stimulating the eye's adjustment function and improving the adjustment flexibility. For example, when the flip shot switches from the positive lens to the negative lens, the eyes need to quickly adjust from the state of looking at close objects to the state of looking at far objects, and vice versa. Through this repeated training, the dynamic adaptability and adjustment speed of the eye muscles are enhanced;

[0100] Step 4: Data recording and analysis

[0101] During the entire training process, the data storage and analysis module records the user's training data in real time. It uses sensors and algorithms to accurately count the number of eye adjustments, fixation time, sight mark tracking accuracy and other information, and stores these data together with parameters such as training time and training mode. After the training, the module uses complex data analysis algorithms to deeply process the stored data. For example, by comparing the changes in the number of eye adjustments in different time periods, the improvement trend of eye adjustment ability can be evaluated; the stability of fixation time can be analyzed to determine whether the user's fixation ability has improved. Based on these analysis results, a detailed training effect evaluation report is generated. The report will show the changes in various indicators of the user in this training in the form of intuitive charts and text descriptions, and provide targeted improvement suggestions based on the user's training situation, such as suggesting that the user increase the difficulty of training, adjust the training mode or extend the training time in the next training, etc., to help users better plan subsequent training plans;

[0102] Step 5: Safety protection and reminders

[0103] The protection and safety module is always in working condition during the training process to ensure the safety of users in all aspects. It monitors the temperature of the device in real time through the temperature sensor. When the temperature of the device is too high, it may affect the performance of the device or cause potential risks to the user. At this time, the module will automatically reduce the power of the device to prevent the device from overheating and damage. At the same time, it will sound an alarm or display a high temperature warning message on the display to remind the user to pay attention to the device status. In addition, the module is also equipped with distance sensors and posture sensors to detect the distance between the user's eyes and the visual mark and the placement of the device. If it is detected that the user's eyes are too close to the visual mark, it may affect the training effect and cause damage to the eyes. The module will issue a prompt sound in time to remind the user to adjust the distance; if the device shakes abnormally, it may cause the training to be interrupted or affect the training accuracy. The module will also suspend the training and prompt the user to readjust the device position to ensure that the user trains in a safe state;

[0104] Step 6: End the training

[0105] When the training time reaches the value pre-set by the user, or the user manually stops the training, the device receives the end command and stops all running modules, such as flip image changes, LED sight mark operation, etc. The display screen switches to the training end interface, showing the detailed data of this training, including the training duration.
