Description

Technical Field

[0002] In today's digital age, myopia is an increasingly serious problem among children and adolescents, and its prevention and control has become a focus of widespread social attention. Myopia not only affects children's daily lives and studies but may also limit their future career options. This is why the technology combining optical lenses with smart wearable devices has emerged.

[0003] Traditional prevention and control glasses have played a certain role in the field of myopia prevention and control, but they have many limitations. Most existing defocus lenses use a single optical design and cannot be dynamically adapted to different eye use scenarios. Especially in the use of eyes by children and adolescents, bad eye habits, such as reading too close, long-term close-up use of the eyes, and incorrect head posture, are important factors that lead to the deepening of myopia. However, traditional glasses cannot detect and correct these bad habits in a timely manner. It is also difficult for parents and teachers to constantly supervise children's eye behavior, which makes children continue to be in an environment at risk of myopia in their daily lives.

[0082] Traditional prevention and control glasses have played a certain role in the field of myopia prevention and control, but they have many limitations. Most of the existing defocus lenses adopt a single optical design and cannot be dynamically adapted according to different eye use scenarios. At the same time, traditional glasses generally lack real-time behavior monitoring and personalized intervention capabilities. Especially in the use of eyes by children and adolescents, bad eye habits, such as reading too close, long-term close-up use of eyes, incorrect head posture, etc., are important factors that lead to the deepening of myopia. However, traditional glasses cannot obtain the user's eye behavior through the user's movements when wearing glasses, and when the eye behavior has a negative impact on the user's vision and vision development, these bad habits cannot be discovered and corrected in time. It is also difficult for parents and teachers to always supervise their children's eye behavior, which makes children continue to be in a myopia risk environment in their daily lives.

[0083] Based on this, in order to improve the problem in the related art that traditional prevention and control glasses cannot promptly detect and correct the user's bad eye behavior, the embodiment of the present application provides the following solution.

[0084] See also Figure 1 , the smart prevention and control glasses 100 provided in an embodiment of the present application are now described.

[0085] The smart prevention and control glasses 100 include a frame 10, two multi-zone defocus lenses 20, a sensor assembly 30, a feedback device 40 and a control device 50; the two multi-zone defocus lenses 20 are connected to the frame 10; the sensor assembly 30 is arranged on the frame 10, for detecting ambient light, the user's reading distance and the posture of the user's head; the feedback device 40 is arranged on the frame 10, for compensating for light and driving the frame 10 to vibrate; the control device 50 is arranged on the frame 10, and the control device 50 is electrically connected to the multi-zone defocus lenses 20, the sensor assembly 30 and the feedback device 40.

[0086] It can be understood that the frame 10 serves as the basic supporting structure of the smart prevention and control glasses 100, similar to the ordinary glasses frame, and provides an installation position for the multi-zone defocus lens 20, the sensor assembly 30, the feedback device 40 and the control device 50 to ensure the stability and relative position relationship of each component.

[0087] The multi-zone defocus lens 20 is a lens having multiple defocus zones, and a microlens structure is integrated inside the lens. The control device 50 can control and adjust the defocus and micro-transmittance of the multi-zone defocus lens 20 through voltage.

[0088] The feedback device 40 may be a combined device integrating the lighting function and the vibration function, or may be a comprehensive device in which the lighting device and the vibration device are separated.

[0089] The control device 50 is used to analyze the data obtained by the sensor assembly 30 and to control the multi-zone defocus lens 20 and the feedback device 40 to work. For example, the control device 50 can be an integrated chip, a micro single-chip microcomputer, etc., but is not limited thereto.

[0090] As can be seen from the above, the smart prevention and control glasses 100 provided in the embodiment of the present application can monitor the user's eye conditions and current environment through the sensor assembly 30, and control the frame 10 to provide feedback based on the eye conditions through the coordinated action of the control device 50 and the feedback device 40, reminding the user to adjust their posture in a timely manner in an intuitive tactile manner. The multi-zone defocus lens 20 can adjust the defocus amount and micro-transmittance density of different areas of its lens through the control device 50, and can adjust the lens area in a targeted manner to better relieve the eye's adjustment pressure, prevent excessive growth of the eye axis, and achieve the purpose of delaying the progression of myopia. Through real-time and automatic intelligent feedback and adjustment functions, there is no need for manual operation by the user, which is convenient and fast. According to the different eye conditions of the user, a personalized prevention and control plan is customized for each user. That is, through the coordinated work of the frame 10, the multi-zone defocus lens 20, the sensor assembly 30, the feedback device 40 and the control device 50, real-time monitoring and intelligent control of the user's eye environment and eye behavior are achieved. It can promptly detect and correct bad eye habits, and at the same time utilize the special optical design of the multi-zone defocus lens 20 to effectively prevent and control the development of myopia, providing comprehensive and intelligent protection for the user's vision health.

[0091] In some embodiments, the multi-zone defocus lens 20 adopts an asymmetric annular distribution, and the defocus gradient is +1.50D to +3.50D.

[0092] It can be understood that the asymmetric annular distribution means that the microlens structure of the multi-zone defocus lens 20 has at least two areas with different densities, symmetrical about the lens's central axis, in different areas of the lens. The microlens structure is distributed in an annular structure centered around the center of the lens. A defocus gradient of +1.50D to +3.50D means that the defocus of the multi-zone defocus lens 20 varies from +1.50D to +3.50D, such as, but not limited to, +1.50D, +2.50D, +3.50D, and so on.

[0093] This arrangement, with its asymmetric annular zone distribution and specific defocus gradient design, more precisely matches the physiological characteristics and eye habits of the human eye. It provides the appropriate defocus for different eye usage scenarios, effectively reducing the strain on the eyes, improving myopia prevention and control, and providing users with a more comfortable and clearer visual experience while reducing the risk of further myopia progression.

[0094] In some embodiments, see Figure 1 The frame 10 includes a frame 11, a nose pad 12, and two temples 13. The frame 11 is hinged to the temples 13, the multi-zone defocus lens 20 is connected to the frame 11, and the nose pad 12 is connected to the frame 11. The feedback device 40 includes a light-emitting device 41 and a reminder device 42. The light-emitting device 41 is arranged at the top of the frame 11, and the reminder device 42 is arranged on the temples 13. The sensor assembly 30 includes a light sensor 31, a distance sensor 32, and at least two motion sensors 33. The light sensor 31 is arranged at one end of the frame 11 near the temples 13; the distance sensor 32 is arranged on the nose pad 12; and the two motion sensors 33 are arranged one-to-one at the hinges between the two temples 13 and the frame 11. The control device 50 is electrically connected to the light-emitting device 41, the reminder device 42, the light sensor 31, the distance sensor 32, and the motion sensor 33.

[0095] It is understandable that the light emitting device 41 can be an LED lamp with fixed brightness and color temperature, or an LED lamp group capable of adjusting different brightness and different color temperatures, etc., but is not limited thereto.

[0096] The reminder device 42 can be a vibrator (such as a micro motor, a piezoelectric ceramic vibrator, etc.) or a sound transmitter (such as a micro speaker, a buzzer, etc.), or a combination of a vibrator and a sound transmitter, etc., but is not limited thereto.

[0097] The photosensor 31 refers to a sensor that can obtain the intensity of the light in the reading environment, and uses the sensitive characteristics of the photosensor to light to convert the intensity change of the ambient light into an electrical signal change. When the ambient light becomes stronger, the electrical signal is enhanced; when the ambient light becomes weaker, the electrical signal is weakened, that is, the light intensity can be obtained by the size of the electrical signal. For example, it can be a photodiode, a photoresistor or a silicon photocell, etc. Here, a photodiode can be preferably used. When there is light, the reverse current of the photodiode will change with the change of light intensity, and it has the characteristics of fast response speed and good linearity. In the smart prevention and control glasses 100, it can quickly capture subtle changes in the intensity of ambient light, and accurately convert the light signal into an electrical signal and transmit it to the control device 50. At the same time, it separates natural light and artificial light sources through dual photodiodes (visible light + infrared), providing technical support for automatic compensation of color temperature deviation.

[0098] The distance sensor 32 is disposed on the nose pad 12, which is located at the center of the glasses near the user's eyes and the reading object, and can effectively measure the distance between the eyes and the reading object. For example, the distance sensor 32 can be a 60GHz millimeter wave radar chip (such as the TI AWR6843), an infrared distance sensor 32 (such as the Sharp GP2Y0A21YK0F), or an ultrasonic distance sensor 32 (such as the HC-SR04), etc., but is not limited to these.

[0099] The motion sensor 33 refers to a sensor that can monitor the movement of the user's head. For example, it can be a six-axis IMU (accelerometer + gyroscope, such as STLSM6DSO). The accelerometer in the six-axis IMU can measure the acceleration change of the object in three axes (usually X, Y, and Z axes). When applied to the smart prevention and control glasses 100, the accelerometer can sense the acceleration, deceleration and changes in the direction of gravity of the user's head in real time, such as the acceleration change caused by the user suddenly lowering his head, raising his head or turning his head quickly. Taking the user's head-down action as an example, the accelerometer can detect the change in the acceleration of the head in the vertical direction, thereby judging the change in the user's head posture in the vertical direction. The gyroscope mainly measures the angular velocity of the object and is used to detect the rotational motion of the object. In the glasses application scenario, the Kalman filter can be used to fuse the accelerometer (static angle) and gyroscope (dynamic angular velocity) data to calculate the head-down angle and the deflection angle. The motion sensor 33 can also be a geomagnetic sensor that determines the direction by sensing the earth's magnetic field, etc., but is not limited to this.

[0100] This arrangement, combined with the rational layout of its components, enables the sensor assembly 30 to comprehensively and accurately collect information such as ambient light, eye distance, and head posture, and promptly transmit it to the control device 50. The control device 50 analyzes and processes this information, precisely controlling the operation of the light-emitting device 41 and the reminder device 42. This collaborative approach provides users with a timely and appropriate lighting environment while effectively reminding them to correct unhealthy eye habits, comprehensively safeguarding their eye health and further enhancing the practicality and effectiveness of the smart prevention and control glasses 100.

[0101] The embodiment of the present application also provides a method for controlling smart prevention and control glasses, which is applied to the smart prevention and control glasses 100 of any of the above embodiments. The smart prevention and control glasses 100 are the executor of the method for controlling smart prevention and control glasses.

[0102] The control methods of smart prevention and control glasses include:

[0103] S100: Acquire ambient light information.

[0104] It will be appreciated that when photosensor 31 is operating, its internal photosensitive element responds to ambient light, generating light signals, which represent ambient light information. These light signals are then converted into electrical signals. Control device 50, through an electrical connection to photosensor 31, reads these electrical signals in real time and converts them into specific information, such as ambient light intensity and illumination changes.

[0105] S200: Determine whether to turn on the light emitting device 41 according to the ambient light information.

[0106] For example, after receiving ambient light information from the photosensor 31, the control device 50 compares the current ambient light intensity with a preset suitable lighting range. If the ambient light intensity is below the lower limit of the preset range, the control device 50 determines that the current ambient light is insufficient and turns on the light-emitting device 41. If the ambient light intensity is within the suitable range, the light-emitting device 41 is turned off.

[0107] S300 , continuously acquiring user posture information based on the distance sensor 32 and the motion sensor 33 ; wherein the user posture information is used to reflect the user's current eye status.

[0108] For example, the distance sensor 32 continuously measures the distance between the eyes and the reading target, and the motion sensor 33 monitors the movement of the user's head in real time, including the amplitude and frequency of actions such as lowering the head, raising the head, and turning the head. This information is summarized as the user posture information.

[0109] S400: Determine feedback information according to user posture information.

[0110] For example, distance and head posture data can be integrated into a composite feature vector using timestamp alignment technology. Head features can then be analyzed based on the composite feature vector to generate corresponding feedback information. Alternatively, user posture information can be input into a learning model, which can then output corresponding feedback information. The learning model is trained using multiple sets of training data, each of which includes user posture information and corresponding feedback information.

[0111] In one possible implementation, see Figure 3 In step S400, feedback information is determined according to the user posture information, including:

[0112] S410, analyzing multiple user posture information to obtain a spatiotemporal feature chain; wherein the spatiotemporal feature chain is used to reflect the changes in the user's eye status over time.

[0113] It can be understood that multiple user posture information received over a period of time is arranged and integrated in chronological order. Each posture information contains spatial information such as eye distance and head posture at a specific moment. In this way, a feature chain containing both time and space dimensions is formed, which is called a spatiotemporal feature chain.

[0114] S420, analyzing the spatiotemporal feature chain to obtain a first spatiotemporal feature and a second spatiotemporal feature; wherein the first spatiotemporal feature is used to reflect the change in the distance between the user's eyes and the reading target, and the second spatiotemporal feature is used to reflect the change in the user's head posture.

[0115] As can be understood, key information related to the distance between the user's eyes and the reading target and head posture is extracted from the spatiotemporal feature chain to form the first spatiotemporal feature and the second spatiotemporal feature. The first spatiotemporal feature focuses on the dynamic changes in the distance between the user's eyes and the reading target, such as the trend of shortening or lengthening the distance and the rate of change of the distance. The second spatiotemporal feature focuses on changes in the user's head posture, including the angle changes of lowering and turning the head, and the distribution of these changes along the time axis.

[0116] S430: Determine feedback information according to the first spatiotemporal feature and the second spatiotemporal feature.

[0117] It is understood that the first spatiotemporal feature can be used to analyze changes in a user's reading distance, generating corresponding feedback information when the reading distance is too close. The second spatiotemporal feature can be used to analyze changes in a user's head posture, generating corresponding feedback information when the head posture affects vision development and health, that is, when the posture change is abnormal. For example, by comparing a preset distance with the current reading distance, and comparing the head posture with a preset head posture, combined with the duration of the current reading posture, it can be determined whether the user is in an abnormal reading state. If so, preset feedback information can be generated. Alternatively, the first and second spatiotemporal features can be input into a learning model, which then outputs corresponding feedback information, and so on, but is not limited to this.

[0118] This setup builds a spatiotemporal feature chain by collecting multiple user posture information over a period of time, comprehensively recording the dynamic changes in the user's eye state over time. This approach can capture the continuous changes in eye distance and head posture, rather than just static information at a single moment. The first and second spatiotemporal features are extracted from the spatiotemporal feature chain, focusing on changes in eye distance and head posture, respectively, to enable targeted analysis of different factors affecting eye use. This segmentation helps to more accurately determine the impact of different factors on vision. Feedback information is generated through a comprehensive analysis based on the first and second spatiotemporal features, combining the two key factors of distance and posture to avoid the limitations of single-factor judgment.

[0119] In one possible implementation, see Figure 4 In step S430, feedback information is determined based on the first spatiotemporal feature and the second spatiotemporal feature, including:

[0120] S431: Analyze the first spatiotemporal feature to obtain an abnormal feature, wherein the abnormal feature is used to indicate that the distance between the user's eyes and the reading target is less than a preset distance.

[0121] It is understood that the preset distance can be manually input or obtained from a control database, etc., but is not limited thereto. A control database refers to a database containing preset data such as preset distances. This data can be obtained through laboratory experiments, on-site measurements and monitoring, and past experience. Once obtained, the collected data is organized, classified, and archived to extract useful information and patterns. The relevant data is then saved to the database to form a control database. When the distance between the user's eyes and the reading target is less than the preset distance, it indicates that the user's eye distance is too close, which may have an adverse effect on vision, i.e., the current distance feature is confirmed to be an abnormal feature.

[0122] S432: Analyze the abnormal characteristics to obtain first feedback information.

[0123] It is understood that different first feedback information can be obtained by analyzing the distance value reflected by the abnormal feature and its duration. For example, if the eye distance is only slightly less than the preset distance and the duration is short, a relatively mild reminder message may be generated; if the eye distance is too close and the duration is long, a stronger reminder message will be generated. It is also possible to analyze the distribution of the abnormal feature in the spatiotemporal feature chain to obtain the trend of the abnormal feature, and obtain different first feedback information based on the trend analysis, and so on, but not limited to this.

[0124] In a possible implementation, in step S430, analyzing the abnormal characteristics to obtain first feedback information includes:

[0125] S4321: Analyze the abnormal characteristics to obtain a first abnormal duration; wherein the first abnormal duration is used to reflect the duration of the abnormal characteristics.

[0126] It can be understood that the mark is made from the moment the abnormal feature is detected, and the duration of the abnormal state of using the eyes too close is recorded according to the number or length of the marks. This length of time is the first abnormal duration.

[0127] S4322: When the first abnormal duration is greater than or equal to the first preset duration, generate a first vibration pattern of the first feedback information.

[0128] It can be understood that the first preset duration is a preset duration value, which can be manually input by a person, or obtained from a prevention and control database, etc., but is not limited to this. The first vibration pattern is a preset feedback information, which can also be manually input by a person, or obtained from a prevention and control database, etc., but is not limited to this. When the duration of using the eyes too close reaches or exceeds the preset first preset duration, it indicates that this bad eye behavior has lasted for a long time and has a greater potential harm to vision. At this time, the control device 50 will generate a vibration instruction with a specific frequency, amplitude and duration, that is, the first vibration pattern of the first feedback information.

[0129] With this setting, by judging and analyzing the abnormal duration, it can effectively reduce false alerts caused by short-term abnormal fluctuations compared to the traditional feedback based on instantaneous abnormal characteristics. This makes the reminder more accurately targeted at the bad eye behaviors that really need attention, which not only ensures the protection of the user's eyesight, but also does not excessively interfere with the user's normal eye activities. In the process of calculating the first abnormal duration, the time information of each abnormal eye use of the user will be recorded. These data can be stored and analyzed, which helps to understand the user's eye habits and provide strong data support for the subsequent further optimization of prevention and control strategies, so as to achieve precise intervention and continuous optimization of user vision protection.

[0130] In a possible implementation, in step S430, analyzing the abnormal characteristics to obtain first feedback information further includes:

[0131] S4323, if there is a second abnormal duration after the first abnormal duration of the abnormal feature, generate a first defocus signal of the first feedback information; wherein the second abnormal duration is used to reflect that the duration of the abnormal feature continuous with the first abnormal duration is greater than the second preset duration.

[0132] It is understood that the first defocus signal is a signal instruction requiring a specific defocus adjustment of the multi-zone defocus lens 20. For example, by increasing the defocus amount, the peripheral retinal image is positioned in front of the retina, thereby inhibiting the growth of the axial length of the eye and playing a role in preventing and controlling myopia. The second preset duration and the first defocus signal are both pre-set information, which can be manually input or obtained from a prevention and control database, etc., but are not limited to these.

[0133] In this way, when there is a second abnormal duration after the first abnormal duration of the abnormal feature, it means that the user still has not adjusted the reading distance after receiving the vibration signal output by the feedback device 40 based on the first vibration mode. At this time, by generating the first defocus signal, the passive is turned into active, and the negative impact of the current reading distance on the user's vision is reduced by actively adjusting the defocus amount of the lens.

[0134] S433: Analyze the second spatiotemporal feature to obtain first angle information and second angle information; wherein the first angle information is used to indicate the angle change when the user lowers his head, and the second angle information is used to indicate the angle change when the user turns his head.

[0135] It can be understood that by extracting the vector features, the corresponding first angle information and second angle information are extracted from the second spatiotemporal features.

[0136] S434: Analyze the first angle information to obtain second feedback information.

[0137] It is understood that the first angle information can be analyzed to obtain the angle value and the corresponding duration, and the corresponding feedback information can be matched. For example, if the angle value is only slightly greater than the preset angle and the duration is short, a relatively mild reminder message may be generated; if the angle value is significantly greater than the preset angle and the duration is long, a stronger reminder message will be generated. Alternatively, the distribution of the angle value in the spatiotemporal feature chain can be analyzed to obtain the overall change trend of the angle value. Based on the trend analysis, the degree of influence of the angle value can be predicted to match different feedback information, and so on, but not limited to this.

[0138] In a possible implementation, in step S434, analyzing the first angle information to obtain second feedback information includes:

[0139] S4341: Analyze the first angle information to obtain a first angle value and a first real-time duration value; wherein the first real-time duration value is used to reflect the duration of the corresponding first angle value.

[0140] It can be understood that when multiple angle values are within the same set angle range, they can be classified as the same angle value. For example, if the angle range includes 0-10°, 10-30° and greater than 30°, when the angle values are 5°, 6°, 15°, and 20°, then 5° and 6° are determined to be the same angle value, and 15° and 20° are the same angle value. If within 1 minute, the user's head-down angle changes from 5° to 6°, wherein the time maintained at 5° is 20s and the time maintained at 6° is 40s, then the first angle value includes 5° and 6°, and the first real-time duration value is 1 minute; if within 1 minute, the user's head-down angle changes from 9° to 15°, wherein the time maintained at 9° is 20s and the time maintained at 15° is 40s, then the first angle value includes 9° and 15°, the first real-time duration value of 9° is 20s, the first real-time duration value of 15° is 40s, and so on.

[0141] S4342: When the first angle value is greater than or equal to the preset angle value, and the first real-time duration value is greater than or equal to the second preset duration, generate a second vibration pattern of the second feedback information.

[0142] It is understood that the preset angle value is a pre-set angle value, and the second vibration pattern is a pre-set vibration pattern. These can be manually input or retrieved from a prevention and control database, etc., but are not limited to these. When the user's head-down angle reaches or exceeds the preset angle value, and this large head-down angle lasts for a period of time that reaches or exceeds a second preset duration, it indicates that there is a problem with the user's current head-down posture, and continuing this posture may pose a significant threat to vision and neck. At this time, the control device 50 generates a second vibration pattern of the second feedback information.

[0143] S4343, monitor the second angle value and the second real-time duration value corresponding to the second angle value after the second vibration pattern is generated, and when the second angle value is greater than or equal to the preset angle value and the second real-time duration value is greater than or equal to the third preset duration, generate a third vibration pattern of the second feedback information.

[0144] It is understood that the third preset duration is a pre-set duration value, which can be manually input by a human, or obtained from a control database, etc., but is not limited thereto. When the second angle value is greater than or equal to the preset angle value, and the second real-time duration value is greater than or equal to the third preset duration, it indicates that the user may not have adjusted their posture in a timely manner or the adjustment effect is poor, and is still in an abnormal state. At this time, the control device 50 will generate a third vibration pattern of the second feedback information of the feedback information, and this vibration pattern may be more intense than the second vibration pattern to further remind the user to adjust to the correct eye posture as soon as possible to effectively protect their eyesight.

[0145] This setup, through multi-stage monitoring of the user's head-down angle and duration and providing different vibration patterns, can gradually strengthen intervention against poor head-down posture. By timely adjusting the reminder method based on the user's actual response, it can more effectively guide users to maintain correct head posture, reduce vision problems caused by poor posture, and enhance the vision protection effect of the smart prevention and control glasses 100.

[0146] S435: Analyze the second angle information to obtain third feedback information.

[0147] It is understood that a user's head tilt to read may be due to vision problems. The third feedback information can be used to provide both vibration and correction, i.e., vibration can be used to reduce the likelihood of the user developing this reading habit. By adjusting the defocus and micro-transmittance density in the multi-zone defocus lens 20, the negative impact of this reading style on vision can be reduced. For example, the user can monitor the angle of head tilt, i.e., analyze the tilt angle and the corresponding duration to determine whether the user has tilted their head and the reason for the tilt, thereby matching the corresponding feedback information. Alternatively, the second angle information can be input into a learning model, which will then output the corresponding third feedback information, and so on, but is not limited to this.

[0148] This setting reduces the risk of myopia caused by behaviors such as using the eyes too close, lowering the head or turning the head in an improper posture by monitoring and reminding users of various bad eye behaviors, providing comprehensive protection for users' eyesight.

[0149] In a possible implementation, in step S435, analyzing the second angle information to obtain third feedback information includes:

[0150] S4351. Analyze the second angle information to obtain angle deflection information; wherein the angle deflection information includes the deflection direction and deflection amount of the user's head.

[0151] It is understood that the deflection direction includes left deflection and right deflection. When the user deflects to the left, the user's right eye is closer to the reading target than the left eye; when the user deflects to the right, the user's left eye is closer to the reading target than the right eye. The deflection amount refers to the deflection angle of the user's head.

[0152] S4352, when the deflection amount is greater than or equal to the preset deflection amount, determine the microlens density improvement target and the defocus compensation target according to the deflection direction, and determine the microlens density improvement target and the defocus compensation target as the third feedback information of the feedback information; wherein, the microlens density improvement target is used to reflect the multi-zone defocus lens 20 with increased micro-transmittance on the side close to the nose pad 12, and the defocus compensation target is used to reflect the multi-zone defocus lens 20 with increased defocus on the side close to the nose pad 12.

[0153] It is understood that the preset deflection amount is a pre-set deflection angle, which can be manually input or retrieved from a control database, etc., but is not limited to these. When deflecting to the left, the target for microlens density increase is the multi-zone defocus lens 20 corresponding to the left eye, and the target for defocus compensation is the multi-zone defocus lens 20 corresponding to the right eye. When deflecting to the right, the target for microlens density increase is the multi-zone defocus lens 20 corresponding to the right eye, and the target for defocus compensation is the multi-zone defocus lens 20 corresponding to the left eye. The values for increasing microlens density and defocus can be preset. The adjustment area is the area of the lens near the nose pad 12.

[0154] With this configuration, when the deflection is greater than or equal to the preset deflection, the microlens density increase target and the defocus compensation target are determined based on the deflection direction. This personalized adjustment method allows for precise parameter adjustments of the multi-zone defocus lens 20 based on the specific deflection of the user's head. For example, when the deflection is left, the microlens density of the multi-zone defocus lens 20 corresponding to the left eye is increased, while the defocus of the multi-zone defocus lens 20 corresponding to the right eye is increased. This allows the optical performance of the lens to better adapt to the user's current eye state, providing the user with a clearer and more comfortable visual experience.

[0155] S500: Control the feedback device 40 to perform feedback based on the feedback information.

[0156] It can be understood that the control device 50 sends instructions to the feedback device 40 based on the generated feedback information, allowing the light-emitting device 41 to fill in the light, the reminder device 42 to vibrate, and the multi-zone defocus lens 20 to adjust the parameters, thereby realizing real-time intervention in the user's eye status and vision control.

[0157] With this setting, the feedback information obtained from the analysis is converted into actual control operations, timely reminding users and adjusting glasses parameters, effectively protecting users' eye health and achieving the purpose of myopia prevention and control.

[0158] In a possible implementation, in step S500, controlling the feedback device 40 to perform feedback based on the feedback information includes:

[0159] S510 , controlling the feedback device 40 to perform vibration feedback based on the first vibration pattern of the first feedback information.

[0160] It can be understood that when the eye distance is too close and reaches the set time, the control device 50 allows the reminder device 42 to vibrate at a specific frequency and amplitude according to the first vibration mode instruction in the first feedback information to remind the user to adjust the eye distance.

[0161] S520, controlling the feedback device 40 to perform defocus increment feedback based on the first defocus signal of the first feedback information; wherein the defocus increment is used to indicate that the defocus amounts of the two multi-zone defocus lenses 20 are increased by a first defocus increment.

[0162] It can be understood that if the distance between eyes is too close and the duration is too long, the control device 50 controls the multi-zone defocus lens 20 to increase the defocus amount according to the first defocus signal, thereby enhancing the ability to prevent and control myopia and reducing damage to vision caused by using eyes too close.

[0163] S530, based on the microlens density improvement target, the side of the corresponding multi-zone defocus lens 20 close to the nose pad 12 is increased to the first preset micro-transmittance density, and based on the defocus amount compensation target, the side of the corresponding multi-zone defocus lens 20 close to the nose pad 12 is increased to the first preset defocus amount.

[0164] It can be understood that when the user's head deflection is too large, the microlens density and defocus amount on the side of the multi-zone defocus lens 20 close to the nose pad 12 are precisely adjusted according to the set microlens density enhancement target and defocus compensation target to optimize the optical performance of the lens and adapt to the vision needs under abnormal eye posture.

[0165] As an optional embodiment of this application, please refer to Figure 6 , the method further includes:

[0166] S10, obtaining user historical behavior data; wherein the user historical behavior data is used to reflect the user's eye usage in a previous period of time.

[0167] It is understood that by recording the user's past eye usage data, such as eye usage distance, reading time, outdoor eye usage time, etc. in different time periods, a comprehensive understanding of the user's eye usage habits and behavior patterns can be achieved. The time period is the observation period, which can be one week, half a month, one month, etc., but is not limited to this.

[0168] S20, analyzing the user's historical behavior data to obtain the user's close-up eye use time and outdoor eye use time; wherein, the user's close-up eye use time is used to indicate the user's average daily close-up reading time, and the outdoor eye use time is used to indicate the user's average daily outdoor eye use time.

[0169] It can be understood that the time information of close-range eye use and outdoor eye use is extracted from the user's historical behavior data to calculate the average daily duration.

[0170] S30, analyzing the time of using eyes at close range to obtain a myopia risk value.

[0171] It is understood that the longer the time spent using the eyes at close range, the greater the myopia risk value. A comparative analysis can be conducted between the user's average daily close-up eye use time and the myopia risk association model derived from research to assess the degree of myopia risk faced by the user due to prolonged close-up eye use and generate a corresponding myopia risk value. The close-up eye use time can also be matched against a prevention and control database to obtain a corresponding myopia risk value, and so on, but not limited to this.

[0172] S40, analyze the duration of outdoor eye use to obtain the prevention and control benefit value.

[0173] It is understandable that the longer the time spent using eyes outdoors, the greater the prevention and control benefits.

[0174] S50, calculating the ratio of the myopia risk value to the prevention and control benefit value to obtain the risk-benefit ratio.

[0175] It can be understood that the risk-benefit ratio = myopia risk value ÷ prevention and control benefit value.

[0176] S60, when the risk-benefit ratio is greater than or equal to the preset ratio, activating the high response mode; wherein the high response mode includes: the defocus amount of the central area of the two multi-zone defocus lenses 20 is increased to a second preset defocus amount, and the microlens density is increased to a second preset micro-transmittance density.

[0177] It is understood that the preset ratio, the second preset defocus amount, and the second preset micro-transmission density are all pre-set values, which may be manually input or retrieved from a prevention and control database, etc., but are not limited thereto. When the risk-benefit ratio reaches or exceeds the preset ratio, indicating that the user's myopia risk is high and the prevention and control effect is relatively insufficient, the high-response mode is activated to enhance the myopia prevention and control capabilities of the multi-zone defocus lens 20 and improve the level of protection for the user's eyesight.

[0178] With this setting, by analyzing the user's historical eye data, evaluating the risk of myopia and the effectiveness of prevention and control, the working mode of the glasses is automatically adjusted according to the evaluation results, realizing personalized and intelligent myopia prevention and control, and more effectively protecting the user's eyesight. Through the immediate feedback mode and long-term data evaluation, a comprehensive vision protection system is built. During the user's daily eye use process such as reading and using electronic devices, the glasses use sensors to monitor the eye status in real time, and send timely feedback reminders to correct bad eye habits; at the same time, based on the analysis results of long-term data, the glasses can automatically adjust the working mode to protect vision from an optical perspective. This multi-dimensional prevention and control method covers multiple links such as eye behavior monitoring, immediate reminders, personalized optical correction, and long-term data optimization, providing comprehensive and continuous protection for the user's vision health, and effectively reducing the risk of myopia occurrence and development.
