Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of optical eyewear technology, and more specifically to a device for controlling the amount of red light radiation emitted by the eye axis. Background Technology

[0002] In the fields of visual health care and specific light applications, red light is widely used in red light vision training scenarios due to its specific physiological effects. However, the red light component in natural light sources (such as the sun) and artificial light sources is mixed with other wavelengths of light, and direct exposure can easily damage the human eye. Moreover, the brightness of the light is difficult to control, failing to meet the needs of safe training. Existing filter glasses are the core application solution, but they suffer from insufficient filtering precision, only achieving a single filtering effect, making it difficult to accurately control the transmission of target wavelength red light, and exhibiting poor stray light cutoff. Therefore, there is a need for binocular smart glasses with precise red light filtering, flexible interpupillary distance adjustment, safe brightness control, and multi-light source adaptation capabilities to address the core shortcomings of traditional solutions.

[0003] However, in practice, it has been found that the following technical problems often exist when using traditional red light radiation modulation devices: Because existing filter glasses use a fixed filter structure, they cannot accurately filter red light in the target wavelength band and have poor cutoff effect on near-infrared light outside the target wavelength band. This results in insufficient purity of red light application, which can easily damage the eyes and fail to meet the needs of safe training. Furthermore, the interpupillary distance adjustment of existing filter glasses mostly relies on moving the entire frame or lenses, resulting in a complex mechanical design and cumbersome adjustment operation. This also fails to adapt to the individual interpupillary distance needs of different users, causing the red light to not be accurately aligned with the eyeball, affecting training effectiveness. Finally, existing filter glasses lack an effective real-time brightness monitoring and adaptive adjustment mechanism and are not equipped with photosensor detection and intelligent adjustment components, making it impossible to dynamically adjust the intensity of light entering the eye according to the brightness of the light source, thus posing a potential eye safety hazard.

[0018] The above embodiments of this disclosure have the following beneficial effects: Through the red light radiation regulation device for controlling the eye axis of some embodiments of this disclosure, the situation that the irradiation is likely to cause damage to the human eye due to insufficient purity of red light application can be reduced, thus meeting the needs of safe training. At the same time, it can be aligned with the eyeball to reduce the impact on the training effect, and the intensity of light entering the eye can be dynamically adjusted according to the brightness of the light source to reduce the potential eye safety hazards. Specifically, the reasons for the numerous technical problems with existing red light radiation regulation devices are as follows: Firstly, existing filter glasses use a fixed filter structure, making it impossible to accurately select the target wavelength of red light. Secondly, the cutoff effect for near-infrared light outside the target wavelength is poor, resulting in insufficient purity of red light application and potential eye damage, failing to meet safe training requirements. Thirdly, existing filter glasses rely heavily on moving the entire frame or lenses for interpupillary distance adjustment, resulting in complex mechanical designs, cumbersome adjustment operations, and an inability to adapt to the individual interpupillary distance needs of different users, causing the red light to be inaccurately aligned with the eyeball, affecting training effectiveness. Finally, existing filter glasses lack effective real-time brightness monitoring and adaptive adjustment mechanisms, and are not equipped with photosensitive detection and intelligent adjustment components, making it impossible to dynamically adjust the intensity of light entering the eye according to the light source brightness, leading to potential eye safety hazards. Based on this, some embodiments of this disclosure provide a red light radiation modulation device for controlling the axial length of the eye. The device comprises a frame, an optical functional group, and a controller. The optical functional group includes symmetrically distributed optical components, each of which is provided with a photosensitive driving structure, a transmittance adjustment component, and a red narrowband filter. The photosensitive driving structure includes a photosensitive chip and a spring-loaded driving device, which drives the photosensitive chip to move within the aperture range of the red narrowband filter. The device is mounted on a mounting base, which slides in conjunction with the adjustment rail of the eyeglass frame to achieve interpupillary distance adjustment. The photosensitive drive structure, the transmittance adjustment component, and the controller are all communicatively connected, and the controller can adjust the transmittance of the transmittance adjustment component based on the illuminance value detected by the photosensitive chip. A display component is located on the outer side of the eyeglass frame to display device status information. The red light radiation control device also includes auxiliary functional components, including a magnetic connection component for connecting an external light source component to the eyeglass frame. Because the red light radiation control device is equipped with a red wide-narrow filter, it can reduce the risk of eye damage caused by insufficient purity of red light, thus meeting safe training requirements. Because the red light radiation control device places a narrow red filter on the mounting base and moves in coordination with the adjustment rail inside the eyeglass frame, it can be aligned with the eyeball, reducing factors that could affect training effectiveness.Because the aforementioned red light radiation regulation device is equipped with a photosensitive drive structure, a controller, and a transmittance adjustment component working together, it can dynamically adjust the intensity of light entering the eye according to the brightness of the light source, thereby reducing potential eye safety hazards.

[0026] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Figure 2 This is a schematic diagram of the optical functional group of the red light radiation modulation device for controlling the axial length of the eye according to the present disclosure. Figure 2 It may include a protective sheet 1, a fixed light-blocking sheet 2, a photosensitive chip 3, a transmittance adjustment component 4, and a red narrowband filter 5.

[0029] Figure 3 This is a schematic diagram of the structure of the light-adjustable component of the red light radiation modulation device for controlling the axial length of the eye according to the present disclosure.

[0030] In some embodiments, such as Figure 1 As shown, the aforementioned red light radiation modulation device may include a frame, an optical functional group, and a controller. The frame can be used to integrate the optical functional group. The controller can be an instrument that processes various types of information. For example, the controller can be a central processing unit. The frame supports the optical functional group, providing it with structural support.

[0031] In some embodiments, such as Figure 2 As shown, the optical functional group includes optical functional components that can be symmetrically distributed. Each optical functional component in the optical functional group can be provided with a photosensitive driving structure, a transmittance adjustment component 4, and a red narrowband filter 5. The photosensitive driving structure, transmittance adjustment component 4, and red narrowband filter 5 can be stacked, and the stacking order is not limited. For example, the transmittance adjustment component 4 can be located between the photosensitive driving structure and the red narrowband filter 5. The optical functional group can include two optical functional components, which can be symmetrically distributed in a binocular configuration. The red narrowband filter 5 can achieve efficient transmission of 600-700nm red light, has a high cutoff rate for stray light, and improves the purity of red light. For example, the red narrowband filter 5 can be a circular filter element prepared by an optical coating process.

[0032] In some embodiments, such as Figure 2As shown, the aforementioned photosensitive driving structure may include a photosensitive chip 3 and a spring-loaded driving device. The spring-loaded driving device can drive the photosensitive chip 3 to move within the aperture range of the aforementioned red narrowband filter 5. The photosensitive chip 3 can detect in real time the illuminance of light (natural light or light emitted by an external light source component) after passing through the red narrowband filter 5. For example, the photosensitive chip 3 is an ambient light sensor chip. The spring-loaded driving device can receive controller commands and drive the photosensitive chip 3 to move flexibly radially within the aperture range of the red narrowband filter 5. For example, the spring-loaded driving device is a miniature electromagnetic actuator. One end of the spring-loaded driving device can be fixed to the aforementioned frame to achieve the driving of the photosensitive chip 3 through extension and retraction.

[0033] In some embodiments, such as Figure 2 As shown, the aforementioned narrow-band red filter 5 can be mounted on a mounting base, which slides in conjunction with the adjustment rail of the frame to achieve interpupillary distance adjustment. Specifically, the mounting base can be used to fix the narrow-band red filter 5 and slide in conjunction with the adjustment rail within the main beam of the frame to achieve interpupillary distance adjustment. For example, the mounting base is a one-piece injection-molded annular component. The mounting base can be embedded within the adjustment rail, thereby allowing the narrow-band red filter 5 to move left and right along the adjustment rail to achieve interpupillary distance adjustment.

[0034] In some embodiments, the photosensitive driving structure, the transmittance adjustment component 4, and the controller can all be communicatively connected. The controller can adjust the transmittance of the transmittance adjustment component 4 according to the illuminance value of the light source (natural light or light emitted by an external light source component) detected by the photosensitive chip 3, thereby adjusting the illuminance value. The communication connection can include, but is not limited to, 3G / 4G, WiFi, Bluetooth, WiMAX, Zigbee, UWB (ultra-wideband), and other currently known or future-developed communication methods. In practice, when the illuminance value detected by the photosensitive chip 3 differs from a preset illuminance value, the controller adjusts the transmittance of the transmittance adjustment component 4 to ensure that the illuminance value detected by the photosensitive chip 3 is the desired illuminance value (preset illuminance value) for eye contact. The specific value of the preset illuminance value is not limited and can be set according to actual needs. The illuminance value characterizes the light intensity of the light source detected by the photosensitive chip.

[0035] In some embodiments, a display component may be provided on the outer side of the eyeglass frame, which is used to display device status information. This device status information may represent the current amount of radiation entering the eye, the illuminance level, remaining battery power, and operating time of the red light radiation control device. For example, the display component may be an OLED screen. The display component may be embedded on the outer side of the eyeglass frame. The current amount of radiation entering the eye may represent the illuminance value entering the human eye at the current moment after adjustment by the transmittance adjustment component 4. The illuminance level may represent the level corresponding to the illuminance value of the red light radiation control device at the current moment. The level may represent a preset parameter corresponding to different illuminance values. For example, the illuminance value may be 750 lux, and the level may be level 1.

[0036] In some embodiments, the aforementioned red light radiation modulation device may further include auxiliary functional components, which may include a magnetic connection component. This magnetic connection component connects an external light source component to the eyeglass frame. Specifically, the magnetic connection component magnetically attracts and secures the external light source component to the eyeglass frame, and detects whether the external light source component is installed. The magnetic connection component can be disposed within the eyeglass frame; its specific location is not predetermined, as long as the connected external light source component can illuminate the eye.

[0037] Optionally, the aperture range of the aforementioned red narrowband filter 5 can be 3~30mm. This aperture range enhances precise filtering while also ensuring structural adaptability.

[0038] Optionally, the transmittance adjustment component 4 can be an electrochromic lens, a light-adjustable component, and a stepper motor, or a polarization adjustment component and a stepper motor. The electrochromic lens can be made of WO3-based electrochromic material, and the transmittance adjustment range of the electrochromic lens can be 5% to 80%. The transmittance of the electrochromic lens is adjusted by regulating the voltage of the electrochromic lens. The light-adjustable component includes a lens group and a diffusion plate. The brightness intensity of the incident light after passing through the diffusion plate is adjusted by regulating the distance between the lens group and the diffusion plate. The brightness intensity range is 20% to 150% of the incident light before passing through the diffusion plate. The lens group can be coaxially arranged with the diffusion plate to adjust the angle of divergence or convergence of the incident light. The polarization adjustment component can include a polarizer group, which includes at least one polarizer. The stepper motor is communicatively connected to the controller. The aforementioned light-adjustable component includes a lens group connected to a stepper motor to control the movement of the lens group. The stepper motor can then adjust the distance between the lens group and the diffusion plate. It should be noted that the lens group can be movable and not fixedly connected to the frame. The transmittance adjustment range of the electrochromic lens can adapt to different light source brightness scenarios, ensuring that the amount of red light radiation entering the eye remains stable within a safe range. The transmittance of the electrochromic lens can be adjusted according to the voltage value. For example, if the voltage is 0.5V, the transmittance is 65%. The range of light intensity can be adjusted according to the distance between the lens group and the diffusion plate. In practice, the controller can adjust the light intensity of the incident light by controlling the stepper motor to adjust the distance between the lens group and the diffusion plate. The lens group can be a fixed lens, a fixed lens assembly, a liquid crystal lens, a liquid lens, a fixed lens + liquid lens, or a fixed lens + liquid crystal lens. The specific composition of the lens group is not specifically limited here. The aforementioned range of light intensity can adapt to diverse light source scenarios and improve the accuracy and effectiveness of the amount of red light radiation entering the eye. The aforementioned diffusion plate can be frosted glass adapted to the shape of the aforementioned lens group. For example, if the distance between the lens group and the diffusion plate is 3mm, then the aforementioned light intensity is 150%. The aforementioned stepper motor drives any polarizer in the aforementioned polarizer group to rotate, and the transmittance is adjusted by changing the polarization direction angle. For example, if the angle of the polarizer group is 30°, the transmittance is approximately 75%.

[0039] The controller is also configured to: The first step involves controlling the stepper motor to drive any one of the polarizers in the polarizer group to rotate in response to a received start command. The start command can represent a user's instruction to activate the red light radiation modulation device.

[0040] The second step is to determine the expected angle value corresponding to the aforementioned polarizer group based on its preset transmittance. The preset transmittance represents the transmittance that the polarizer group is required to achieve. The expected angle value represents the angle between the polarization directions that at least two polarizers in the polarizer group must achieve. In practice, the controller can determine the expected angle value corresponding to the preset transmittance from a set of preset polarization angle correspondence information. The preset polarization angle correspondence information in the set of preset polarization angle correspondence information represents the correspondence between the preset transmittance and the expected angle value. For example, the preset polarization angle correspondence information could be: "Preset transmittance: Target value for red light transmittance entering the eye is 75%; Expected angle value can be: 30°".

[0041] Third, in response to detecting that the polarization angle of the aforementioned polarizer group is the expected angle value, the aforementioned stepper motor is turned off. The aforementioned polarization angle can characterize the angle between the polarization directions of at least two polarizers included in the aforementioned polarizer group at the current moment.

[0042] Fourthly, in response to detecting that the polarization angle of the aforementioned polarizer group is not the expected angle value, the polarization angle of the aforementioned polarizer group is changed to adjust the transmittance of the aforementioned polarizer group. The adjustment of the polarization angle represents the adjustment of the transmittance of the aforementioned polarizer group. In practice, the stepper motor drives the angle of a single polarizer in the aforementioned polarizer group to the expected angle value.

[0043] Optionally, a silicone protective layer is further provided on the surface of the photosensitive chip 3, and the radial travel range of the photosensitive chip 3 is 0~30mm. The silicone protective layer can reduce damage to the fixed light-shielding sheet 2 or the transmittance adjustment component 4 caused by the movement of the photosensitive chip 3.

[0044] Optionally, the aforementioned magnetic connection assembly includes a magnetic interface and a Hall sensor. The magnetic interface connects the external light source assembly to the eyeglass frame, securing it with magnetic force. The Hall sensor is positioned adjacent to the magnetic interface. Upon detecting a magnetic signal, the Hall sensor determines the connection status based on signal stability. This signal stability indicates that the effective duration of the continuous output of the magnetic electrical signal detected by the Hall sensor exceeds a preset 1 second. The connection status indicates the magnetic engagement between the external light source assembly and the eyeglass frame. The external light source assembly can stably output target red light, meeting eye safety illumination standards. For example, the external light source assembly can be a red LED light source module. For example, the wavelength range of the target red light is 600-700 nm.

[0045] The controller is also configured to: The first step involves switching the operating mode of the red light radiation control device to an external light source mode in response to the magnetic attraction signal detected by the Hall sensor. The magnetic attraction signal represents the connection between the external light source component and the magnetic interface. The operating mode can represent either an external light source mode or a non-external light source mode. The external light source mode represents the operating state of the red light radiation control device when it is paired with an external light source component. The non-external light source mode represents the operating state of the red light radiation control device when it is paired with a natural light source.

[0046] Optionally, the controller further includes a timer. Each optical component in the optical function group is also provided with a protective sheet 1 and a fixed light-shielding sheet 2. The timer can be used to count the time the user uses the red light radiation control device. One side of the fixed light-shielding sheet 2 is adjacent to one side of the photosensitive chip 3, and the protective sheet 1 is adjacent to the other side of the fixed light-shielding sheet 2. Both the fixed light-shielding sheet 2 and the protective sheet 1 are disposed on the lens frame. The other side of the photosensitive chip 3 is adjacent to the transmittance adjustment component 4.

[0047] The controller is also configured to: First, in response to the detection of the stop information of the aforementioned timer, the protective plate 1 is controlled to spring back. The stop information indicates that the red light radiation modulation device has been discontinued.

[0048] The second step involves controlling the protective sheet 1 to spring back in response to the detection that the illuminance increase received by the red light radiation regulation device exceeds a preset value or the red light radiation regulation device is turned off. The illuminance increase can characterize the growth rate of red light illuminance transmitted through the red narrowband filter 5 per unit time, as well as the upward trend of red light radiation entering the eye. For example, the preset value could be 50% / s, and the unit time could be 1 second.

[0049] The controller is also configured to: The first step involves, in response to the detection that the battery level of the aforementioned red light radiation regulation device is less than the target battery level, switching the red light radiation regulation device to standby mode and controlling the display component to display a charging reminder message. The target battery level represents the minimum battery threshold required for the red light radiation regulation device to maintain stable operation of its core regulation functions. For example, the target battery level could be 20%. The core regulation function represents the function of controlling the red light radiation regulation device to keep the amount of red light radiation entering the eye within a safe range. The specific value of this safe range is not limited and can be adjusted according to actual needs. The charging reminder message represents the remaining battery level of the aforementioned red light radiation regulation device at the current moment.

[0050] In addressing the technical problems mentioned above, and considering the application scenario—users using natural light for red light training at home (e.g., with windows open)—the significant spectral differences in natural light at different times of day often lead to the following technical problem: traditional filter glasses rely solely on fixed filters for single-color filtering, failing to accurately identify changes in the proportion of target red light and stray light. This results in a consistently insufficient effective dose of red light for visual training, making it difficult to achieve the desired effect. Consequently, red light visual training becomes completely ineffective or yields poor results, wasting users' time and investment, and potentially impacting visual health improvement due to prolonged ineffective training. To meet the following requirements for this application scenario: adaptability to multiple filtering needs, adaptability to significant spectral differences in natural light, and adaptability to active triggering adjustment, we have decided to adopt the following solution: Optionally, the aforementioned red light radiation control device may further include a spectral recognition component, which is communicatively connected to the aforementioned controller. The aforementioned display component may also be used to display spectral detection information, and is configured to display text indicating a replacement light source when the red light purity is lower than a preset value. The aforementioned spectral recognition component may include a spectral sensor and a spectral analysis chip, wherein the detection wavelength coverage range of the spectral sensor is 550~750nm. The aforementioned spectral analysis chip is used to process the spectral data collected by the spectral sensor. The spectral sensor and the aforementioned spectral analysis chip may be mounted on the aforementioned mounting base. The spectral sensor and the aforementioned spectral analysis chip may be mounted between the aforementioned fixed light-shielding plate 2 and the aforementioned red narrowband filter 5 via a snap-fit ​​structure, and are coaxially arranged with the optical path of the aforementioned optical functional group. The aforementioned spectral detection information can characterize whether the light source meets the usage requirements. For example, the preset value may be 60% red light purity. The aforementioned spectral sensor may be a sensor that collects light spectral signals, and the aforementioned spectral analysis chip can process the raw spectral signals collected by the spectral sensor into quantized spectral data. For example, red light is 600~700nm, and the intensity of red light accounts for 60%. The spectral sensor can be a miniature spectral sensor, and the spectral analysis chip can be a digital signal processor.

[0051] The controller is also configured to: The first step involves controlling the aforementioned spectral sensor to acquire spectral data in response to the activation of the red light radiation modulation device. The aforementioned spectral analysis chip processes the raw signal acquired by the spectral sensor into spectral data. This spectral data characterizes the proportion of red light intensity at the current moment. For example, if the red light intensity is 750 lux, the red light intensity accounts for 75%.

[0052] The second step is to determine the difference adjustment information for the corresponding spectral data based on the aforementioned spectral data. This difference adjustment information characterizes the difference between the actual red light intensity ratio and the preset value. In practice, the controller can determine the difference between the actual red light intensity ratio and the preset value as the difference adjustment information. The specific value of the preset light intensity ratio is not limited and can be adjusted according to actual needs.

[0053] The third step involves determining the aforementioned difference adjustment information as target parameter information and controlling the transmittance adjustment component 4 to perform a difference adaptation operation. The target parameter information characterizes the target parameters of the transmittance adjustment component 4. In practice, the difference adaptation operation can be achieved by the controller adjusting the transmittance adjustment component 4 according to the target parameter information to suppress stray light interference.

[0054] The above-described technical solution, as an inventive point of this disclosure, solves the technical problem of "red light visual training being completely ineffective or significantly less effective." The reasons for this ineffectiveness are as follows: When users conduct red light training at home using natural light (e.g., with windows open), traditional filter glasses rely solely on a fixed filter for single-color filtering, making it impossible to accurately identify changes in the proportion of target red light and stray light. This results in a consistently insufficient effective red light dose for visual training, making it difficult to achieve the expected effect. Consequently, red light visual training becomes completely ineffective or significantly less effective, wasting the user's time and effort, and potentially impacting visual health improvement due to prolonged ineffective training. Solving these factors allows for accurate identification of changes in the proportion of red light and stray light, reducing the insufficient effective red light dose for visual training, improving effectiveness, and minimizing wasted time and effort. To achieve this effect, the controller described in some embodiments of this disclosure can collect current spectral data through the spectral sensor, analyze the difference between the light intensity ratio of red light data and preset values ​​in real time, and control the transmittance adjustment component 4 to perform corresponding transmittance adjustment, thereby reducing the situation where the effective red light dose for actual visual training is insufficient.

[0055] In addressing the technical problems mentioned above, and considering the application scenario—where multiple students in a school frequently use a single red light radiation control device for red light training—the following technical problem often arises: Traditional red light radiation control glasses lack the function of automatically generating appropriate illuminance levels based on pupillary distance. This results in mismatched pupillary distance and illuminance levels when students switch between devices, leading to red light radiation levels that cannot meet the eye tolerance needs of students with different pupillary distances, or insufficient red light radiation affecting training effectiveness. Furthermore, the lack of interruption detection and red light pause linkage mechanisms means there is a lack of recognition and response to interruptions in the wearing state. This results in red light continuing to be emitted even when students remove the glasses, leading to strong light irradiation and safety risks, and wasted energy. To address the following requirements for this application scenario: adaptability to multiple users, suitability for interrupted use, and adaptability to training interruptions, we have decided to adopt the following solution: Optionally, the aforementioned auxiliary function components include a capacitive contact sensor and an eye distance recognition sensor, both of which are communicatively connected to the controller. The capacitive contact sensor can be a sensor that determines whether the red light radiation modulation device is in contact with the user. For example, the capacitive contact sensor can be a patch-type miniature capacitive touch sensor. The eye distance recognition sensor can be a sensor capable of determining the user's eye distance. For example, the eye distance recognition sensor can be a binocular vision miniature recognition sensor. Both the capacitive contact sensor and the eye distance recognition sensor are embedded in the frame.

[0056] The aforementioned controller is also configured to: The first step involves, in response to the activation of the aforementioned red light radiation modulation device and the detection of a stable contact signal by the capacitive contact sensor, controlling the eye distance recognition sensor to collect eye distance data and controlling the capacitive contact sensor to collect contact signals at preset time intervals. The stable contact signal indicates whether the capacitive contact sensor continuously detects whether the user is wearing the device within a preset time period. The eye distance data indicates the distance between the user's left and right eyes. For example, the preset time could be 3 seconds, and the preset time interval could be 0.5 seconds.

[0057] The second step involves determining the user type of the red light radiation regulation device based on the aforementioned interpupillary distance (IPD) data. The user type represents the population category to which the user of the red light radiation regulation device belongs. For example, the population category could be elementary school students or junior high school students. The controller can determine the preset IPD corresponding information from a preset IPD corresponding information set, and then use the user type determination criteria included in the determined preset IPD corresponding information as the basis for triggering the determination of the user type. The user type determination criteria can represent the relationship between different IPD value ranges and corresponding population categories (e.g., IPD ≤ 55mm corresponds to children). The preset IPD corresponding information in the preset IPD corresponding information set can represent the correspondence between IPD data, user type determination criteria, and red light adaptation parameters for the corresponding population. The red light adaptation parameters can represent a set of parameters that ensure the safety and effectiveness of red light entering the eyes for the user type. This parameter set may include user type, transmittance, and illuminance level. For example, the preset eye distance information can be: "Current eye distance data: 48mm; User type determination criteria: eye distance ≤ 55mm is for children; Red light adaptation parameters for the corresponding group: target value of red light transmittance into the eye is 50%, illuminance level is low (300-500 lux); User type: children".

[0058] The third step is to control the display component to show gear selection information based on the user type mentioned above. This gear selection information indicates the recommended gear for the user type.

[0059] Fourth, in response to the detection that the contact signal interruption exceeds a preset time, a control command is generated. The aforementioned contact signal interruption can indicate that the capacitive contact sensor detected the user removing the red light radiation control device. For example, the preset time could be 10 seconds. The control command can indicate that the red light radiation control device cuts off the power supply to the red light source and transmittance adjustment component 4 to enter standby mode, and remembers the current setting, transmittance adjustment parameters, and other usage statuses so that the user can directly restore the previous settings when wearing and activating the device again.

[0060] Fifth, according to the aforementioned control instructions, the transmittance of the transmittance adjustment component 4 is controlled to a preset transmittance, and the timing is paused. The display component is also controlled to display a preset pause message. The preset transmittance can be a transmittance that will not affect the user's vision through direct sunlight. For example, the preset transmittance could be 15%. The preset pause message could indicate that the device has been paused (removed for more than 10 seconds) and will resume after 2 seconds of being put back on.

[0061] Step six: In response to the detection that the contact signal has recovered for more than a preset time, a recovery command is generated. This recovery command indicates that the transmittance adjustment component 4 should be restored to its transmittance parameters before the pause, the timing for resuming training should be initiated, the display component should be switched to show information indicating the resumption of use, and the red light adaptation parameters (such as illuminance level and target transmittance) corresponding to the current user type should be maintained. In practice, if the capacitive contact sensor detects the recovery of the contact signal and it lasts for 2 seconds, it is determined that the device should be worn again.

[0062] Step 7: According to the aforementioned recovery command, control the transmittance adjustment component 4 to the target transmittance and resume timing, and control the display component to return to normal operation. The target transmittance can characterize the transmittance parameter of the device before the red light radiation regulation device is paused. For example, the target transmittance is 50%. The normal operation state can characterize the display component continuously displaying real-time red light adaptation parameters.

[0063] The above-mentioned technical solution, as an inventive point of this disclosure, solves the technical problem of "red light radiation not being able to adapt to the eye tolerance needs of users with different interpupillary distances, and strong light irradiation causing safety risks." The reasons for the situation where red light radiation cannot be adapted to the eye tolerance needs of users with different interpupillary distances and strong light irradiation causes safety risks are as follows: When multiple students in a school frequently use a single red light radiation control device for red light training, traditional red light radiation control glasses do not have the function of automatically generating an appropriate illuminance level based on interpupillary distance. As a result, when students switch to use the red light radiation control device, they rely solely on the students to manually adjust the interpupillary distance and illuminance level selection. This mismatch between interpupillary distance and illuminance level leads to the red light radiation not being able to adapt to the eye tolerance needs of students with different interpupillary distances, or the red light radiation being insufficient, affecting the training effect. Furthermore, due to the lack of a usage interruption detection and red light pause linkage mechanism, there is a lack of recognition and response to interruptions in the wearing state. This results in the red light continuing to be emitted even when students remove the glasses, leading to strong light irradiation causing safety risks, and ineffective light emission causing waste. If the above factors are addressed, the situation where the device cannot adapt to the eye tolerance needs of users with different interpupillary distances can be reduced, thereby lowering the risk of safety hazards caused by accidental exposure to strong light. To achieve this effect, the controller described in some embodiments of this disclosure can determine the user type by collecting interpupillary distance data from the interpupillary distance recognition sensor, and suggest the recommended setting. This can reduce the situation where the device cannot adapt to the eye tolerance needs of users with different interpupillary distances. Furthermore, the controller can detect whether the device is in normal use by using the capacitive contact sensor. If it is determined that the device is not in use, the red light exposure is stopped and the timer is paused until the device is put on again for continued operation, thus reducing the risk of safety hazards caused by accidental exposure to strong light.

[0064] In addressing the technical problems mentioned above, and considering the application scenario—where multiple students in a school frequently use a single red light radiation modulation device for red light training—the following technical problem often arises: Because existing technologies lack a hardware detection mechanism for the filter, the inability to effectively block stray light after filter wear or contamination is overlooked. This results in non-target wavelength light mixed in with the incoming light, posing a potential risk of eye damage to individuals with sensitive eyes. To meet the following requirements for this application scenario: adaptability to high-frequency user needs, suitability for wear detection, and provision of replacement prompts, we have decided to adopt the following solution: Optionally, the aforementioned red light radiation regulation device may further include a transmittance detection sensor, which is communicatively connected to the aforementioned controller. The transmittance detection sensor may be a sensor capable of detecting the output of the transmittance adjustment component 4. For example, the transmittance detection sensor is an integrated transmittance detection chip sensor. The location of the transmittance detection sensor is not limited; it only needs to detect the transmittance of the aforementioned red narrowband filter 5. For example, the transmittance detection sensor may be mounted on the eyeglass frame.

[0065] The aforementioned controller is also configured to: First, in response to the detection of the activation of the aforementioned red light radiation modulation device, the following detection steps are performed: The first sub-execution step involves controlling the transmittance detection sensor to acquire the transmittance of the red narrowband filter 5. The transmittance characterizes the ability of the red narrowband filter 5 to transmit target red light. For example, the transmittance could be 70%.

[0066] The second sub-execution step involves determining the attenuation rate of the red narrowband filter 5 based on the aforementioned transmittance and the preset transmittance. The preset transmittance characterizes the standard transmittance of red light by the red narrowband filter 5 under normal conditions. The attenuation rate characterizes the extent to which the filtering performance of the red narrowband filter 5 deteriorates due to factors such as long-term use, thus determining whether the filter needs replacement. For example, the preset transmittance could be 85%. In practice, the attenuation rate can be used to characterize the ratio between the difference between the actual measured transmittance and the preset transmittance and the preset transmittance itself.

[0067] The third sub-execution step, in response to determining that the attenuation rate is greater than a preset threshold, controls the aforementioned red light radiation regulation device to enter a preset standby state. The preset threshold represents the maximum attenuation limit at which the aforementioned red narrowband filter 5 can function normally, and is a critical value used to determine whether the filter is contaminated or needs to be discontinued and replaced. The preset standby state represents cutting off the power supply to the red light radiation regulation device, maintaining only low-power operation of the controller and display components, while simultaneously informing the user of the filter's status. For example, the preset threshold is 30%.

[0068] The fourth sub-execution step involves controlling the red light radiation regulation device to enter a normal start-up mode in response to determining that the attenuation rate is less than the aforementioned preset threshold. This normal start-up mode indicates that the red light radiation regulation device is operating normally and has entered a stable working state.

[0069] The second step involves re-executing the aforementioned detection steps in response to the detection of a user-inputted re-inspection command. This re-inspection command can represent a user's instruction to the red light radiation control device to re-detect the attenuation rate of the filter after cleaning and maintaining it.

[0070] The third step involves determining that the red narrowband filter 5 is in a failed state in response to the detection that the number of times the user inputs a re-inspection command exceeds a preset number, and generating replacement information. The preset number represents the number of times the user attempts to clean and maintain the filter. Cleaning and maintenance can represent wiping the filter with a lens. The failed state indicates that the filter's attenuation rate remains above a preset threshold, resulting in a loss of filtering performance. The replacement information indicates that the controller drives the display component to display text indicating that the filter needs to be replaced. For example, the preset number could be 3 times.

[0071] Fourth, in response to the detection of a replacement operation and the attenuation rate being less than a preset threshold, the red light radiation regulation device is controlled to enter the normal startup mode. In practice, the replacement operation indicates that the user has replaced the filter, and then the attenuation rate is detected to be less than the preset threshold, at which point the red light radiation regulation device starts working normally.

[0072] The above-described technical solution, as an inventive point of this disclosure, solves the technical problem of "the inability to effectively block stray light after filter wear," which leads to the mixing of non-target wavelength light in the incoming light, posing a potential risk of eye damage to people with sensitive eyes. The reason for this is as follows: When multiple students in a school frequently use a single red light radiation control device for red light training, the lack of a filter hardware detection mechanism in the existing technology causes the problem of the filter being unable to effectively block stray light after wear or contamination to be overlooked. This results in the mixing of non-target wavelength light in the incoming light, posing a potential risk of eye damage to people with sensitive eyes. Solving the above factors can reduce the risk of potential eye damage to people with sensitive eyes caused by filter hardware failure. To achieve this effect, the controller in some embodiments of this disclosure uses the transmittance collected by a transmittance detection sensor to determine the attenuation rate, reminding the user that there is contamination on the lens. If the attenuation rate still exceeds a preset threshold after multiple attempts by the user, the user is reminded to replace the filter, thus reducing the potential risk of eye damage caused by filter hardware failure.

[0073] The above embodiments of this disclosure have the following beneficial effects: Through the red light radiation regulation device for controlling the eye axis of some embodiments of this disclosure, the situation that the irradiation is likely to cause damage to the human eye due to insufficient purity of red light application can be reduced, thus meeting the needs of safe training. At the same time, it can be aligned with the eyeball to reduce the impact on the training effect, and the intensity of light entering the eye can be dynamically adjusted according to the brightness of the light source to reduce the potential eye safety hazards. Specifically, the reasons for the numerous technical problems with existing red light radiation regulation devices are as follows: Firstly, existing filter glasses use a fixed filter structure, making it impossible to accurately select the target wavelength of red light. Secondly, the cutoff effect for near-infrared light outside the target wavelength is poor, resulting in insufficient purity of red light application and potential eye damage, failing to meet safe training requirements. Thirdly, existing filter glasses rely heavily on moving the entire frame or lenses for interpupillary distance adjustment, resulting in complex mechanical designs, cumbersome adjustment operations, and an inability to adapt to the individual interpupillary distance needs of different users, causing the red light to be inaccurately aligned with the eyeball, affecting training effectiveness. Finally, existing filter glasses lack effective real-time brightness monitoring and adaptive adjustment mechanisms, and are not equipped with photosensitive detection and intelligent adjustment components, making it impossible to dynamically adjust the intensity of light entering the eye according to the light source brightness, leading to potential eye safety hazards. Based on this, some embodiments of this disclosure provide a red light radiation modulation device for controlling the axial length of the eye. The device comprises a frame, an optical functional group, and a controller. The optical functional group includes symmetrically distributed optical components, each of which is provided with a photosensitive driving structure, a transmittance adjustment component, and a red narrowband filter. The photosensitive driving structure includes a photosensitive chip and a spring-loaded driving device, which drives the photosensitive chip to move within the aperture range of the red narrowband filter. The device is mounted on a mounting base, which slides in conjunction with the adjustment rail of the eyeglass frame to achieve interpupillary distance adjustment. The photosensitive drive structure, the transmittance adjustment component, and the controller are all communicatively connected, and the controller can adjust the transmittance of the transmittance adjustment component based on the illuminance value detected by the photosensitive chip. A display component is located on the outer side of the eyeglass frame to display device status information. The red light radiation control device also includes auxiliary functional components, including a magnetic connection component for connecting an external light source component to the eyeglass frame. Because the red light radiation control device is equipped with a red wide-narrow filter, it can reduce the risk of eye damage caused by insufficient purity of red light, thus meeting safe training requirements. Because the red light radiation control device places a narrow red filter on the mounting base and moves in coordination with the adjustment rail inside the eyeglass frame, it can be aligned with the eyeball, reducing factors that could affect training effectiveness.Because the aforementioned red light radiation regulation device is equipped with a photosensitive drive structure, a controller, and a transmittance adjustment component working together, it can dynamically adjust the intensity of light entering the eye according to the brightness of the light source, thereby reducing potential eye safety hazards.
