Description

Technical Field

[0001] The present invention relates to the field of smart wearable technology, and in particular to glasses for preventing and controlling improper eye use, a control method thereof, and a system for preventing and controlling improper eye use. Background Art

[0002] In recent years, 3C electronic products have been widely popularized and even penetrated into the children's market. While providing entertainment for children, they have also brought about problems such as excessive eye strain from using electronic screens and the hazards of blue light. This has led to a gradual increase in the myopia rate among children, and has shown a trend of younger age.

[0003] As a result, prevention and control devices have come into the spotlight, and they come in a wide variety, including chest-mounted, head-mounted, and desktop-mounted posture correctors. These devices generally use proximity sensors to detect distance and integrate vibration and voice prompts for close-range notifications. While these devices can be effective, they also have certain design flaws. For example, head-mounted posture correctors have a poor appearance, chest-mounted posture correctors have low detection accuracy, and desktop-mounted posture correctors have very limited application scenarios. Furthermore, the close-range notification methods are not clear and intuitive, are complex to operate, and fail to achieve effective reminders, and can easily bore children. Summary of the Invention

DETAILED DESCRIPTION

[0073] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive efforts.

[0074] The first embodiment of the present invention is a pair of glasses 100 for preventing and controlling improper eye use, comprising: a frame body, provided with a PNLC partitioned lens 110, wherein the PNLC partitioned lens 110 includes a plurality of independent partitions; two temples, respectively connected to the two ends of the frame body; an improper eye use prevention and control parameter sensing module 120, provided on the frame body or the temples, for sensing improper eye use prevention and control parameters; a main control module 130, provided in the frame body or the temples, independently connected to each partition in the PNLC partitioned lens 110 and connected to the improper eye use prevention and control parameter sensing module 120, for controlling the fogging state of each partition in the PNLC partitioned lens 110 according to the improper eye use prevention and control parameters, as shown in the control diagram. Figure 1 shown.

[0075] In this embodiment, the frame body may include multiple components, including a frame, nose pads, etc. in addition to the PNLC partitioned lens 110. The two temples are respectively a first temple and a second temple, wherein one end of the frame body is connected to the first temple and the other end is connected to the second temple, and the two temples can be connected to one end of the frame body by any form of connector.

[0076] Each partition in the PNLC partition lens 110 is independently connected to the corresponding control terminal in the main control module 130, and is connected to the common terminal of the main control module 130 to access the common potential. There is no limitation on the shape and number of the partitions in the PNLC partition lens 110, and they can be configured according to actual needs, as long as the control circuit corresponding to the partition design is used to achieve independent control of each partition. In order to achieve the purpose of partition control, the PNLC partition lens 110 includes a first glass layer and a second glass layer that are bonded together, and a PNLC liquid crystal poured between the first glass layer and the second glass layer. The control circuit is etched on the glass layer, and the control circuit is used to realize the atomization control of the PNLC liquid crystal between the first glass layer and the second glass layer of each partition, including controlling it to enter the atomized state and controlling it to eliminate the atomization and become a fully transparent state.

[0077] In the process of controlling the PNLC partitioned lens 110 to enter the atomization state, a PWM modulation signal is output to the common terminal through the control circuit, and a voltage level opposite to the common terminal is output to the regional control terminal (each partition of the PNLC partitioned lens 110 shares a common terminal, and each partition includes a regional control terminal), forming a pressure difference with a gradually increasing duty cycle, so that each partition in the PNLC partitioned lens gradually becomes atomized (a single partition gradually enters the atomized state from the transparent state within a preset time, such as 2s, 3s, etc.). In the process of controlling the PNLC partitioned lens 110 to enter the transparent state, a PWM modulation signal is output to the common terminal through the control circuit, and a voltage level identical to the common terminal is output to the regional control terminal (each partition of the PNLC partitioned lens 110 shares a common terminal, and each partition includes a regional control terminal), forming a pressure difference with a gradually decreasing duty cycle, so that each partition in the PNLC partitioned lens gradually becomes transparent.

[0078] In one embodiment, the first and second glass layers are made of ITO glass. During the partitioning process, the ITO glass is exposed, developed, and acid-etched to separate it into an inner zone and several outer zones. Each zone is then wired so that the resulting PNLC zoned lens 110 achieves zoned atomization. The control circuitry can be designed using a flexible circuit board and wired according to control requirements. Specifically, if partial zone control is required, wiring is performed only on the zones requiring atomization control. For example, if wiring is performed only on the outer zones, some of the inner zones are left blank, resulting in better transparency and minimal visual impact while still providing a user reminder. Alternatively, if wiring is performed only on the inner zones, some of the outer zones are left blank, achieving both a user reminder and light blocking.

[0079] like Figure 2The diagram shows the structure of a PNLC segmented lens 110 in one embodiment. As can be seen, a single lens comprises four segments: Segment 1, Segment 2, Segment 3, and Segment 4, from outer to inner. Each segment has its own independent control circuit, corresponding to SEG1, SEG2, SEG3, and SEG4, sharing a common terminal, COM. In other embodiments, when implementing inner and outer segmentation, the number of segments can be adjusted based on the lens size, and a single lens can even be controlled as a single segment.

[0080] To meet the diverse needs of users for glasses, in other embodiments, the glasses 100 for preventing and controlling eye problems also have a blue light protection function. That is, a blue light protection layer is also attached to the surface of the PNLC partitioned lens 110, which achieves the blue light protection function through film reflection. For this blue light protection layer, the transmittance requirement is: the overall transmittance reaches more than 80%. For the blue light band above 455nm, the transmittance is higher than 80%; the transmittance of short-wave harmful blue light of 415-445nm is less than 80%, and the transmittance of blue-violet light of 385-415nm is less than 75%. The filter rate requirement is: the overall filter rate is about 20%, and shall not exceed 25%. In addition, the glasses 100 for preventing and controlling improper eye use can also meet the functions of explosion-proof, anti-fingerprint, anti-oil, anti-scratch, waterproof, anti-static, anti-reflective film, anti-UV, etc. according to needs, and corresponding treatment can be performed on the surface of the PNLC partitioned lens 110. For example, an anti-fingerprint layer is adhered to the surface of the PNLC partitioned lens 110 to achieve the anti-fingerprint function, and an explosion-proof layer (ARAF explosion-proof layer, etc.) is adhered to the surface of the PNLC partitioned lens 110 to achieve anti-reflective film, anti-fingerprint, explosion-proof and other functions.

[0081] During the process of preventing and controlling improper eye use, the improper eye use prevention and control parameter sensing module 120 senses the improper eye use prevention and control parameters, and then the main control module 130 controls the fogging state of each partition in the PNLC partition lens 110 according to the improper eye use prevention and control parameters.

[0082] In one embodiment, the parameter sensing module 120 for preventing and controlling improper eye use includes a distance sensing module, which is configured on the surface of the frame body and is used to sense the distance parameter between the configured direction and the target object and send it to the main control module 130. After receiving the distance parameter, the main control module 130 compares it with the preset distance threshold. When the sensed distance parameter is less than the preset distance threshold, it is determined that the current distance is too close, and the main control module 130 starts to control each partition in the PNLC partition lens 110 to enter the fogging state; when the sensed distance parameter is not less than the preset distance threshold, it is determined that the current state is normal. The above-mentioned preset distance threshold can be set according to actual conditions, such as being set to 20cm, 30cm, etc. or even farther; in addition, the preset distance threshold can also be an interval value (such as 5-30cm, etc.). When the sensed distance parameter changes between the interval values, it is determined that the distance is too close. This embodiment has been improved. In addition to including a parameter comparison unit for comparing the distance parameter sensed by the distance sensing module with a preset distance threshold, the main control module 130 also includes a timing unit, a duration judgment unit, and a fog control unit. The timing unit is configured to start timing when the parameter comparison unit determines that the distance is currently too close; the duration judgment unit is configured to determine whether the duration of the too close state is greater than a first preset time threshold; and the fog control unit is configured to control each partition to enter a fog state according to a preset rule when the duration judgment unit determines that the state has lasted for greater than the first preset time threshold. The PNLC partition lens has independent partitioning rules, the order in which each partition enters the fog state under different partitioning rules, and the fogging time. The first preset time threshold can be set according to actual conditions, such as 3s, 4s, or even longer. The distance sensing module is a distance sensor that can be configured in the middle of the frame body, i.e., above the nose pads and between the two lenses, to improve the accuracy of the sensing data.

[0083] The independent partitions of the PNLC partitioned lens can be divided according to actual application requirements. Any solution that achieves the purpose of preventing and controlling poor eye use by partitioning the lens and then controlling the fogging state of each partition through the PNLC in the lens is included in this embodiment, such as:

[0084] 1) A single lens is divided into inner and outer partitions that surround each other in a nested manner. Specifically, when there are 0 outer partitions, the entire lens is considered as the inner partition; when there is 1 inner partition and 1 outer partition, the inner partition is nested within the outer partition; when there is 1 inner partition and multiple outer partitions, the multiple outer partitions are nested layer by layer, and the inner partition is nested within the innermost outer partition. Figure 2In the illustrated PNLC zoned lens, a single lens is divided into one inner zone (zone 4) and three outer zones (zones 1, 2, and 3). Zone 1 is the outermost zone, zone 2 is the middle zone, and zone 3 is the innermost zone. As shown, zone 4 is nested within zone 3, zone 3 is nested within zone 2, and zone 2 is nested within zone 1, forming three outer ring zones. The direction from zone 1 to zone 4 is the direction from outer ring to inner ring. In this zoned arrangement, the shapes of the zones are not specifically limited and can be regular or irregular. In practical applications, for ease of etching, the zones can be formed into regular shapes, such as the outer and inner zones each having a circular / elliptical / regular polygonal outer shape; in another example, the inner zone has a circular / elliptical outer shape, while the outer zone has a regular polygonal outer shape; in another example, the outer zone has a circular / elliptical outer shape, while the inner zone has a regular polygonal outer shape. When multiple outer circle partitions are included, the outer circle shapes of the outer circle partitions can be the same or different. In order to enhance the fun, irregular shaped partitions can be selectively formed, such as forming an inner circle partition in the shape of a certain animal; Figure 2 As shown, the inner and outer circles are divided into corresponding shapes according to the shape of the lens. In order to facilitate the wiring of the common end of each partition and to be more ergonomic, a single lens can be divided into 1-4 circle partitions, especially divided into Figure 2 The four partitions shown include one inner partition and three outer partitions.

[0085] 2) Forming a number of independent partitions on a single lens by segmenting. In this partitioning method, the shapes of the partitions are also not specifically limited and can be regular or irregular. For example, a single lens can be divided into four block-shaped partitions: upper left, upper right, lower left, and lower right. Another example is etching a number of independent square partitions (one, two, three, four, or even more) on the lens. Another example is etching a number of parallel strip-shaped partitions (two, three, or even more) in the horizontal or vertical direction on the lens.

[0086] In the above two partition division methods, each partition is independent of each other, that is, the outermost circles of the partitions will not cross each other. In other partitioning methods, partitions can also be formed by crossing each other. For example, by etching two intersecting circular areas on the lens, three control partitions are finally formed (including the intersection area and the non-intersection area of the two circular areas), and so on, as long as the partitions finally formed can facilitate wiring for partition control.

[0087] The order in which each partition enters the atomized state can also be set according to actual conditions. To improve the user experience, atomization control can be performed on a partition-by-partition basis according to the layout, or the partitions can be grouped and atomized according to the layout (even all blocks can be divided into a single group for synchronous control). For example, when a single lens is divided into an inner ring partition and several outer ring partitions that surround each other through a nested approach, when entering the atomized state, the control can be implemented by gradually atomizing from the outer ring partition to the inner ring partition; correspondingly, when entering the transparent state, the control can be implemented by gradually transparentizing from the inner ring partition to the outer ring partition. For another example, when several independent partitions are formed on a single lens through a block approach, when entering the atomized state, the control can be implemented by gradually atomizing from left to right / top to bottom / outer ring block to inner ring block; correspondingly, when entering the transparent state, the control can be implemented by gradually atomizing from right to left / bottom to top / inner ring block to outer ring block, etc. In addition, in actual applications, it is also possible to choose to atomize only some of the partitions, and then wire the control to the partitions that need to be atomized. The time for each partition to gradually enter the fog state from the transparent state and the time for gradually entering the transparent state from the fog state can also be adjusted according to actual conditions, such as 4s, 5s, 7s or even more. In order to improve the user experience, the time for gradually entering the transparent state from the fog state can be designed to be shorter than the time for gradually entering the fog state from the transparent state.

[0088] In one embodiment, a single lens includes Figure 2 The four partitions shown are (area A, area B, area C, and area D, from the outer circle to the inner circle, in order). When the distance sensing module detects that the distance to the target in front is between 5 and 30 cm and this state persists for 3 seconds, it is determined to be in a too-close state. The main control module 130 controls both lenses to gradually fog from the outer circle to the inner circle, and completely fogs within 8 seconds (area A is completely fogged), issuing a mandatory reminder. The corresponding haze changes at different times are shown in Table 1, where Hmax represents the peak haze, and Eg:Hmax25% represents 1 / 4 of the peak haze, that is, the haze percentages in the table represent the percentage of the haze peak value Hmax.

[0089] Table 1: Fog changes at different times during distance sensing

[0090] time Area and fog 3-4s A:0-25%, B:0, C:0, D:0 4-5s A:25%-50%, B:0-25%, C:0, D:0 5-6s A:50%-75%, B:25%-75%, C:0-25%, D:0 6-7s A:75%-100%, B:50%-75%, C:25%-50%, D:0 7-8s A:100%—, B:75%-100%, C:50%-100%, D:0 8-9s A:100%—, B:100%—, C:75%-100%, D:0-33% 9-10s A:100%—, B:100%—, C:100%—, D:33-66% 10-11s A:100%—, B:100%—, C:100%—, D:66%-100%

[0091] In the process of the main control module 130 controlling each partition to enter the fogging state, the distance sensing module continuously detects the distance between the configuration direction and the target object and determines whether it is still in a state of being too close. If it is determined to be in a normal state, the main control module 130 controls each partition to restore to full transparency within a second preset time threshold (such as 1s, 2s, etc.) to prevent misjudgment. In the above example, at any time during the period of 3-9s, if the distance sensing module senses that the distance parameter has returned to normal (the sensed distance parameter is not less than the preset distance threshold), the main control module 130 further controls the lens to return to full transparency within 1.5s, and the fogging process is terminated. It should be clear that the above only exemplifies the fog changes at different times and in different areas. In actual applications, they can be adjusted according to needs.

[0092] In another embodiment, the parameter sensing module 120 for preventing and controlling improper eye use includes a sitting posture sensing module, which is configured on the frame body or the temple (the first temple or the second temple) and is used to sense the tilt parameter of the wearer's head and send it to the main control module 130. After receiving the tilt parameter, the main control module 130 compares it with a preset tilt threshold. When the sensed tilt parameter is greater than the preset tilt threshold, it is determined that the current sitting posture is improper, and the main control module 130 begins to control each partition in the PNLC partition lens 110 to enter a fogging state; when the sensed tilt parameter is not greater than the preset tilt threshold, it is determined that the current state is normal. The above-mentioned preset tilt threshold can be set according to actual conditions, such as 15°, 20°, or even larger. This embodiment is improved. In addition to a parameter comparison unit for comparing the sensed tilt parameter with a preset tilt threshold, the main control module 130 also includes a timing unit, a duration judgment unit, and a fog control unit. The timing unit is used to start timing when the parameter comparison unit determines that the current distance is too close; the duration judgment unit determines whether the duration of the improper sitting posture is greater than a first preset time threshold; the fog control unit is used to control each partition to enter the fog state according to preset rules when the duration judgment unit determines that the state lasts for longer than the first preset time threshold. The preset rules include the division rules of the PNLC partition lens into independent partitions, the order in which each partition enters the fog state under different division rules, and the fog change time. The above-mentioned first preset time threshold can be set according to actual conditions, such as being set to 3s, 4s, or even more. PNLC partitioned lenses can also be divided into independent partitions according to actual application needs. Any solution that uses the PNLC inside the lens to control the fogging state of each partition after partitioning the lens to achieve the purpose of preventing and controlling poor eye use is included in this embodiment. For example, as mentioned above, a single lens is divided into an inner circle partition and several outer circle partitions (the outer circle can be 0, in which case the entire lens is regarded as an inner circle partition); for example, a single lens is divided into four partitions: upper left, upper right, lower left, and lower right. In actual applications, in order to facilitate the wiring of the common end of each partition and to be more ergonomic, a single lens can be divided into 1-4 circle partitions, especially divided into the following: Figure 2 The four zones shown, including one inner zone and three outer zones, facilitate the goal of gradually transitioning from outer to inner zones to achieve a gradual fogging or transparency. The order and timing of each zone entering the fogging state can also be set based on actual conditions. For example, in one example, a single lens includes one inner zone and one outer zone. During the fogging process, the outer zone gradually fogs toward the inner zone, with the inner zone beginning fogging two seconds after the outer zone begins fogging, and both the inner and outer zones require seven seconds to fully fog. Furthermore, the posture sensing module can be a gyroscope, an angle sensor, or the like.

[0093] In one embodiment, a single lens includes Figure 2 The four partitions shown are (area A, area B, area C, and area D, respectively, from the outer circle to the inner circle). The sitting posture sensing module is a gyroscope. When the gyroscope detects that the wearer's head is tilted more than 20 degrees and this state lasts for 3 seconds, it is determined to be in an improper sitting posture (head tilt). The main control module 130 controls both lenses to gradually fog from the outer circle to the inner circle, and completely fogs within 8 seconds (area A), issuing a mandatory reminder. The corresponding haze changes at different times are shown in Table 2, where Hmax represents the peak haze, and Eg:Hmax25% represents 1 / 4 of the peak haze, that is, the haze percentage in the table represents the percentage of the haze peak value Hmax.

[0094] Table 2: Changes in fog at different times during tilt angle sensing

[0095] time Area and fog 3-4s A:0-25%, B:0, C:0, D:0 4-5s A:25%-50%, B:0-25%, C:0, D:0 5-6s A:50%-75%, B:25%-75%, C:0-25%, D:0 6-7s A:75%-100%, B:50%-75%, C:25%-50%, D:0 7-8s A:100%—, B:75%-100%, C:50%-100%, D:0 8-9s A:100%—, B:100%—, C:75%-100%, D:0-33% 9-10s A:100%—, B:100%—, C:100%—, D:33-66% 10-11s A:100%—, B:100%—, C:100%—, D:66%-100%

[0096] During the process of the main control module 130 controlling each partition to enter the fogging state, the sitting posture sensing module continuously detects the wearer's tilt parameters and determines whether the wearer is still in an improper sitting posture. If it is determined to be in a normal state, the main control module 130 controls each partition to restore to full transparency within a second preset time threshold (such as 1s, 2s, etc.) to prevent misjudgment. In the above example, at any time during the period of 3-11s, if the sitting posture sensing module senses that the tilt parameter has returned to normal (the sensed tilt parameter is not greater than the preset tilt threshold), the main control module 130 further controls the lens to return to full transparency within 1.5s, and the fogging process is terminated. It should be clear that the above only exemplifies the fog changes at different times and in different areas. In actual applications, they can be adjusted according to needs.

[0097] In another embodiment, the parameter sensing module 120 for preventing and controlling improper eye use includes a distance sensing module and a sitting posture sensing module. The working principle of the module is the same as in the above embodiment and will not be elaborated here. The difference is that, during operation, the distance sensing module and the sitting posture sensing module work separately. When the main control module 130 adjusts the fogging state of the lens according to the distance parameter sensed by the distance sensing module, the sitting posture sensing related functions are shielded; when the main control module 130 adjusts the fogging state of the lens according to the tilt parameter sensed by the sitting posture sensing module, the distance sensing related functions are shielded. In other words, when the main control module 130 controls the fogging state of the lens according to the sensing parameters of one of the sensing modules, even if the other sensing module also senses that the lens needs to be controlled to enter the fogging state, no processing is performed. After the previous control process is completed, if it is still determined that the lens needs to be controlled to enter the fogging state, processing will be performed again.

[0098] The above embodiment is improved to obtain the present embodiment. In the present embodiment, the glasses 100 for preventing and controlling improper eye use further include a temple state sensing module 140, which is arranged in the temple (the first temple or the second temple) and is connected to the main control module 130 for sensing the opening and closing state of the temple. The main control module 130 controls the on / off state of the glasses' improper eye use prevention and control function according to the opening and closing state of the temple.

[0099] In this embodiment, the temple state sensing module 140 disposed within the first temple or the second temple is used to sense whether the temple is in an unfolded or folded state. When the temple is detected to have transitioned from a folded state to an unfolded state, the function for preventing and controlling improper eye use of the glasses is enabled, i.e., the glasses enter an on state. When the temple is detected to have transitioned from an unfolded state to a folded state, the function for preventing and controlling improper eye use of the glasses is disabled, i.e., the glasses enter an off state. The temple state sensing module 140 can be of various types, such as one or more of a Hall sensor, a gyroscope, and an angle sensor (sensing angle change data), and can determine the open or closed state of the temple by sensing relevant data from the temple. In one example, the temple state sensing module 140 is a Hall sensor. To achieve the sensing purpose, a Hall sensor can be set on one of the temples and a magnet can be set on the other temple. In this way, when the first temple and the second temple are in a folded state, the distance between the Hall sensor and the magnet is close, and the induced magnetic field strength is large (greater than a preset magnetic field strength threshold); when the first temple and the second temple are in an unfolded state, the distance between the Hall sensor and the magnet is far, and the induced magnetic field strength is small (not greater than a preset magnetic field strength threshold), so that the opening and closing state of the temple is determined according to the magnetic field strength induced by the Hall sensor.

[0100] To enhance the user experience, the glasses can also be equipped with a power-on / off indicator module. For example, when the main control module 130 controls the glasses to enter the power-on state, the indicator module lights up for a certain period of time (e.g., 2 seconds, 5 seconds, etc.) and then automatically turns off, prompting the user to enter the power-on state. In one embodiment, a Hall effect sensor is placed inside the temple. When the temple is detected to be in the extended state, the glasses automatically enter the power-on state; when the temple is detected to be in the folded state, the glasses automatically enter the power-off state. After the power-on detection is completed, the indicator light on the temple side lights up for 5 seconds and then automatically turns off, notifying the user that the glasses have been turned on.

[0101] The present embodiment is obtained by improving the above embodiment. In the present embodiment, the glasses for preventing and controlling improper eye use 100 further include a wearing status sensing module 150, which is arranged on the inner side of the frame body or the temple (the first temple or the second temple) and is connected to the main control module 130, and is used to sense the wearing status of the glasses and send it to the main control module 130. The main control module 130 controls the working status of the improper eye use prevention and control function according to the wearing status of the glasses.

[0102] In this embodiment, the wearing state sensing module 150 is used to sense whether the user is wearing the glasses 100 for preventing and controlling improper eye use. When it is detected that the user is wearing glasses, it enters the "working" state, and the main control module 130 controls the parameter sensing module 120 for preventing and controlling improper eye use to start working; when it is detected that the user takes off the glasses, it enters the "standby" state, and the main control module 130 controls the parameter sensing module 120 for preventing and controlling improper eye use to start sleeping, thereby realizing intelligent control of the working state of the entire system. In actual applications, the wearing state sensing module 150 can be an infrared sensor. When the user wears glasses, the infrared sensor receives the reflected infrared light to realize intelligent detection of the wearing state of the glasses. In other instances, the wearing state sensing module 150 can also be other forms of sensing modules, such as a gravity sensing module (which achieves the purpose by sensing the change of gravity acceleration), etc. There is no specific limitation here, as long as the purpose of the invention can be achieved.

[0103] In such Figure 3 In the embodiment shown, the eyeglasses 100 for preventing and controlling improper eye use include both a temple state sensing module 140 and a wearing state sensing module 150. The temple state sensing module 140 first senses whether the temple is in an unfolded or folded state. Upon detecting that the temple has transitioned from a folded state to an unfolded state, the eyeglasses' improper eye use prevention and control function is activated, and the system enters a power-on state. In the power-on state, if the wearing state sensing module 150 detects that the user is wearing the glasses, the system enters a "working" state, and the main control module 130 controls the improper eye use prevention and control parameter sensing module 120 to begin operating. Upon detecting that the user has taken off the glasses, the system enters a "standby" state, and the main control module 130 controls the improper eye use prevention and control parameter sensing module 120 to enter a dormant state, thereby achieving intelligent control of the entire system's operating state.

[0104] In the above embodiment, to improve detection accuracy and prevent misjudgments, when the wearing status sensing module 150 detects that the user has removed their glasses, after a preset time (e.g., 1 second, 2 seconds, etc.) has expired, the main control module 130 controls the poor eye use prevention parameter sensing module 120 to enter a dormant state. In one example, when the system is powered on and detects that the user is wearing glasses, it automatically enters the "working" state. If it detects that the user has removed their glasses, it enters the "standby" state after 1 second, and the system enters a dormant state.

[0105] The above embodiment is improved to obtain this embodiment. In this embodiment, Figure 4As shown, the glasses for preventing and controlling improper eye use 100 also include a speaker module 160 and a wireless communication module 170, wherein the speaker module 160 is arranged in the temple (the first temple or the second temple) and is connected to the main control module 130, and is used to start or stop playing multimedia files under the control of the main control module 130, and to play call voice (answering calls) under the control of the main control module; the wireless communication module is arranged in the temple (the first temple or the second temple) and is connected to the main control module 130, and is used to receive multimedia files sent by an external smart terminal and play them through the speaker module, and to transmit voice with an external smart terminal.

[0106] In this embodiment, multimedia files are played through the speaker module 160, including playing a "wearing detection prompt tone" after detecting that the user is wearing glasses, playing music files, learning course audio files, etc.; the speaker module 160 is also used for the glasses to play voice when making a voice call with an external smart terminal. The position of the speaker in the first temple and / or the second temple can be adjusted according to actual conditions, close to the user's ear, so that the user can receive the files it plays. In order to save resources, when it is detected that the user takes off the glasses, the main control module 130 controls the speaker module 160 to stop playing. The wireless communication module 170 is used to interact with the outside world for data, including receiving control information, uploading sensing parameters, etc., and can be a wifi module, a bluetooth module, an infrared module, etc.

[0107] In one embodiment, the wireless communication module is a Bluetooth module, which cooperates with the speaker module 160 to realize the functions of a Bluetooth headset and the transmission of multimedia files and call voice. The Bluetooth module can be connected to an external smart terminal independently by ordinary connection or through an APP. Among them, ordinary connection is used for users (children) to listen to music, take online classes, and answer calls on a daily basis, such as connecting to a smart terminal such as a learning machine that is also equipped with a Bluetooth module. The APP connection is used for parents to obtain information such as their children's eye data through a mobile phone APP via a BLE connection.

[0108] During the first pairing process, turn on the Bluetooth function of the glasses and the smart terminal at the same time, search for the device name and complete the pairing and connect directly; or follow the instructions in the APP, search for the device name, click to complete the pairing and connect directly.

[0109] After completing the first pairing, during normal connection:

[0110] [Connect]: Users can directly search for the device name through the device's settings module to connect, without the need for multiple pairings. After the connection is successful, the main control module 130 controls the player module in the glasses to play a "connection success prompt tone" to prompt the user.

[0111] [Disconnect]: When the smart terminal disconnects the Bluetooth or the Bluetooth connection is disconnected due to over-distance, the main control module 130 controls the player module in the glasses to play the "disconnect prompt tone".

[0112] [Reconnect]: After a certain period of disconnection (such as 2s, 3s, etc.), the glasses will automatically reconnect to the first device in the history connection list. Each time you turn on the glasses, they will automatically reconnect to the first device in the history connection list.

[0113] APP connecting:

[0114] [APP Connection]: When the user enters the APP data page, they can directly connect to the glasses via BLE by refreshing or clicking connect to obtain data or make settings. During the APP connection, the normal connection between the user device and the glasses and the playback of multimedia files are not affected and are independent of each other.

[0115] [Disconnect]: Automatically disconnect when the user exits the APP data page.

[0116] The above examples illustrate how the glasses are connected to external user devices or apps when a Bluetooth module is configured. In other examples, adjustments can be made based on actual conditions and are not specifically limited here.

[0117] The above embodiment is improved to obtain the present embodiment. In this embodiment, the glasses 100 for preventing and controlling improper eye use also include: a power module, which is arranged in the temple (the first temple and / or the second temple), and is used to power each module in the glasses; a first power display module, which is arranged on the side of the temple (the first temple or the second temple), and is connected to the main control module 130, and is used to display the power of the power module under the control of the main control module 130, including the remaining power display at startup and / or the low power display and / or the charging power display.

[0118] In the present embodiment, power module is configured in the first temple and / or the second temple, so that each electronic component in the glasses is powered. Simultaneously, the first electric quantity display module is configured on the first temple or the second temple side, and the electric quantity in the power module is displayed. For the first electric quantity display module concrete form, it can be arranged according to actual demand, such as configuring liquid crystal display module in the temple, and battery power is displayed in real time; For another example, the indicator lights of several different colors are configured to prompt different electric quantities. The electric quantity of the power module can be adjusted according to the electronic device configured in the glasses, and under normal conditions, the power module needs to meet the guarantee of battery life certain time (such as 5h etc.) when starting multimedia playback and reverse PNLC reminder (atomization control). For the charging of the power module, the mode of configuring charging interface on one side of the temple of the configuration power module can be adopted to realize the purpose, or other methods can be adopted to realize the purpose, and no specific limitation is done here.

[0119] In one embodiment, the first power display module includes a red and green light. During operation, the first power display module displays once when the device is turned on and lasts for a preset time (such as 2s, 3s, 5s, etc.) to prompt the user. After turning on the device, if the power module is less than the preset low power threshold (such as 20% or 25% of the full power), it displays red. If the power of the power module exceeds the preset low power threshold, it displays green. When the battery capacity reaches the preset low power threshold and the preset minimum power threshold (such as 5% of the full power), a low power reminder is given respectively. A "low power reminder sound effect" is emitted through the speaker module 160, and the device enters low power mode. The power indicator light turns red and flashes. The flashing cycle and duration can be set according to actual conditions, such as flashing for 3 seconds with a cycle of 200ms. During the charging process, if the power is less than the preset low power threshold, the indicator light is in a red flashing state. The flashing cycle and duration can be set according to actual conditions, such as flashing for 1 second with a cycle of 200ms. If the power module's charge level is ≥ the preset low-charge threshold but < the full charge level, the indicator light flashes green. The flashing cycle and duration can also be configured based on actual conditions, such as flashing for 1 second at a 200ms cycle and turning green when fully charged. The above configuration information for the power module charge indicator is merely an example. In other instances, the notification method, the light, and the duration of the notification can be adjusted based on actual conditions and are not specifically limited here.

[0120] The present invention also provides a system for preventing and controlling improper eye use, which includes, in addition to the above-mentioned improper eye use prevention and control glasses 100, a glasses case 200 matching the improper eye use prevention and control glasses 100, and is equipped with a power supply battery, a charging interface and a second power display module, wherein the power supply battery is arranged in the glasses case 200, for powering the power module in the improper eye use prevention and control glasses 100; the charging interface is arranged on the glasses case 200, for charging the power supply battery; the second power display module is arranged on the glasses case 200, for displaying the power supply battery power, including low power display and / or charging power display.

[0121] In this embodiment, the glasses case 200 is compatible with the glasses 100 for preventing and controlling eye problems. Besides being used to store the glasses, the glasses case also provides power to the power module inside the glasses through the power supply battery installed therein. When charging, the temples are folded up and placed in the glasses case 200. The power supply battery then supplies power to the power module inside the glasses. Charging can be achieved by configuring a matching interface. When the power supply battery is exhausted, charging is performed through the charging interface (e.g., a Type-C interface) located on the back of the glasses case 200.

[0122] The second battery level indicator module configured in the glasses case 200 is similar to the first battery level indicator module configured in the glasses and is used to display the battery level. The specific form of the second battery level indicator module can be configured according to actual needs, such as configuring an LCD module in the temple to display the battery level in real time, or configuring a plurality of different colored indicator lights to indicate different battery levels. The battery level is adjusted based on the power level of the power module in the glasses.

[0123] In one example, the second power display module includes a red and green light. When charging using the charging port, the indicator light provides a power indication: If the battery level is less than a preset low-battery threshold, the indicator light flashes red. The flashing cycle and duration can be set according to actual conditions, such as flashing for 1 second with a cycle of 200ms. If the battery level is ≥ the preset low-battery threshold but less than the full battery level, the indicator light flashes green. The flashing cycle and duration can also be set according to actual conditions, such as flashing for 1 second with a cycle of 200ms. When fully charged, the indicator light flashes green.

[0124] In the embodiment where the glasses are equipped with a Bluetooth module, the glasses case 200 is also equipped with a Bluetooth pairing function key, and pairing indicators (such as blue indicators) are provided on the glasses and the glasses case 200. During the first pairing process, place the glasses in the glasses case 200 and long-press the function key (such as 2s, 3s, etc.). The indicator lights on the glasses case 200 and the glasses will flash synchronously. At this time, turn on the device Bluetooth to search for the device name and complete the pairing and direct connection. Alternatively, follow the instructions in the app to search for the device name and click to complete the pairing and direct connection.

[0125] In another embodiment, Figure 5 As shown, the system for preventing and controlling eye problems includes, in addition to the eye problems prevention and control glasses 100 and the glasses case 200, a control terminal 300, which is connected to the eye problems prevention and control glasses 100 via a built-in wireless communication module 170. The control terminal 300 is used to receive eye problems prevention and control parameters including wearing time data and / or close-range use time data and / or distance parameters and / or tilt parameters sent by the eye problems prevention and control glasses 100, and to generate statistical reports on the wearing conditions of the eye problems prevention and control glasses 100 based on the eye problems prevention and control parameters, generate eye health recommendations, and send instructions to the eye problems prevention and control glasses 100 based on the wearing time data to remind the wearer of the wearing time.

[0126] In this embodiment, after the control terminal 300 connects to the glasses via an app, the user can also set a single usage time for the glasses through the control terminal 300, such as 30 minutes, 40 minutes, etc. When the user is detected wearing the glasses, the timing unit in the main control module 130 starts counting, and the control terminal 300 obtains the timing data (wearing time). If the wearing time reaches the set time, a command is sent to the glasses to control the speaker module 160 through the main control module 130 to issue a voice reminder. To improve the accuracy of the usage time statistics, if the user interrupts wearing (takes off the glasses) within the set time, and the time exceeds a preset time (such as 3 minutes, 5 minutes, etc.), the time is reset when the glasses are put on again. For time statistics, its statistical rules can be set according to actual conditions. For example, in one example, time statistics are not affected by standby or shutdown, that is, shutdown and standby cannot reset time statistics; the time indicator light is off when the glasses are off and remains on in standby and working mode; and the time statistics are reset when the user does not wear the glasses for 8 consecutive hours.

[0127] The terminal device collects data on wearing time, close-range use time, distance parameters, tilt parameters, and other parameters related to poor eye use prevention and control, and generates statistical reports and eye health recommendations. Close-range use time refers to the distance pre-set by the user, such as the time the distance to the target object is less than 60cm. The app also allows for custom rest time, atomization reminder switches, voice reminder switches, and ear protection modes.

[0128] In order to strengthen monitoring, a light sensing module is also configured in the glasses to sense the light intensity information and color temperature information of the ambient light and record and send it to the control terminal 300. Parents can automatically obtain the data when connecting the glasses via BLE on the APP side.

[0129] In one example, Figure 6 As shown, the bad eye prevention glasses 100 include a frame body, a PNLC partition lens 1, and a single PNLC partition lens 110 includes Figure 2 The four partitions shown (area A, area B, area C, and area D, from the outer circle to the inner circle) are shown. The main control module 4 is located on one of the temples, the speaker module 3 is located on both the first and second temples near the ears, and the power module 5 is located at the ends of the first and second temples. A charging module 6 is also located on one side of the speaker module 3 on one temple, and the distance sensor 2 is located between the two lenses. During operation, the main control module 4 controls the fogging state of the PNLC partitioned lens 1 using the distance parameter sensed by the distance sensor 2, while also emitting a prompt tone through the speaker module 3.

[0130] The present invention also provides a control method for glasses for preventing and controlling bad eye use, which is applied to the above-mentioned glasses for preventing and controlling bad eye use, such as Figure 7 As shown, the control method of the glasses for preventing and controlling improper eye use includes: S10 obtaining improper eye use prevention and control parameters sensed by an improper eye use prevention and control parameter sensing module, and the improper eye use prevention and control parameter sensing module is configured on the frame body or the temple; S20 controlling the fogging state of each partition in the PNLC partitioned lens according to the improper eye use prevention and control parameters, and the PNLC partitioned lens is configured on the frame body.

[0131] Obtaining the improper eye use prevention and control parameters sensed by the improper eye use prevention and control parameter sensing module includes: a distance parameter between the sensing configuration direction and the target object, and / or a tilt parameter of the wearer's head; controlling the fogging state of each partition in the PNLC partitioned lens according to the improper eye use prevention and control parameters includes: controlling the fogging state of each partition in the PNLC partitioned lens according to the distance parameter sensed by the distance sensing module and / or the tilt parameter sensed by the sitting posture sensing module.

[0132] In one embodiment, controlling the fogging state of each partition in the PNLC partitioned lens according to the distance parameter sensed by the distance sensing module includes: determining whether the distance parameter sensed by the distance sensing module is less than a preset distance threshold; if so, determining that the distance is currently too close; determining whether the duration of the too close state is greater than a first preset time threshold; if so, controlling each partition to enter the fogging state according to preset rules, the preset rules including the division rules of the PNLC partitioned lens into independent partitions, the order in which each partition enters the fogging state under different division rules, and the fog change time. The above-mentioned preset distance threshold can be set according to actual conditions, such as being set to 20cm, 30cm, etc. or even farther. The first preset time threshold can be set according to actual conditions, such as being set to 3s, 4s, etc. or even more. In actual applications, the distance sensing module is a distance sensor, which can be configured in the middle position of the frame body, that is, above the nose pad and in the middle of the two lenses, to improve the accuracy of the sensing data.

[0133] The independent partitions of the PNLC partitioned lens can be divided according to actual application requirements. Any solution that achieves the purpose of preventing and controlling poor eye use by partitioning the lens and then controlling the fogging state of each partition through the PNLC in the lens is included in this embodiment, such as:

[0134] 1) A single lens is divided into inner and outer partitions that surround each other in a nested manner. Specifically, when there are 0 outer partitions, the entire lens is considered as the inner partition; when there is 1 inner partition and 1 outer partition, the inner partition is nested within the outer partition; when there is 1 inner partition and multiple outer partitions, the multiple outer partitions are nested layer by layer, and the inner partition is nested within the innermost outer partition. Figure 2In the illustrated PNLC zoned lens, a single lens is divided into one inner zone (zone 4) and three outer zones (zones 1, 2, and 3). Zone 1 is the outermost zone, zone 2 is the middle zone, and zone 3 is the innermost zone. As shown, zone 4 is nested within zone 3, zone 3 is nested within zone 2, and zone 2 is nested within zone 1, forming three outer ring zones. The direction from zone 1 to zone 4 is the direction from outer ring to inner ring. In this zoned arrangement, the shapes of the zones are not specifically limited and can be regular or irregular. In practical applications, for ease of etching, the zones can be formed into regular shapes, such as the outer and inner zones each having a circular / elliptical / regular polygonal outer shape; in another example, the inner zone has a circular / elliptical outer shape, while the outer zone has a regular polygonal outer shape; in another example, the outer zone has a circular / elliptical outer shape, while the inner zone has a regular polygonal outer shape. When multiple outer circle partitions are included, the outer circle shapes of the outer circle partitions can be the same or different. In order to enhance the fun, irregular shaped partitions can be selectively formed, such as forming an inner circle partition in the shape of a certain animal; Figure 2 As shown, the inner and outer circles are divided into corresponding shapes according to the shape of the lens. In order to facilitate the wiring of the common end of each partition and to be more ergonomic, a single lens can be divided into 1-4 circle partitions, especially divided into Figure 2 The four partitions shown include one inner partition and three outer partitions.

[0135] 2) Forming a number of independent partitions on a single lens by segmenting. In this partitioning method, the shapes of the partitions are also not specifically limited and can be regular or irregular. For example, a single lens can be divided into four block-shaped partitions: upper left, upper right, lower left, and lower right. Another example is etching a number of independent square partitions (one, two, three, four, or even more) on the lens. Another example is etching a number of parallel strip-shaped partitions (two, three, or even more) in the horizontal or vertical direction on the lens.

[0136] In the above two partition division methods, each partition is independent of each other, that is, the outermost circles of the partitions will not cross each other. In other partitioning methods, partitions can also be formed by crossing each other. For example, by etching two intersecting circular areas on the lens, three control partitions are finally formed (including the intersection area and the non-intersection area of the two circular areas), and so on, as long as the partitions finally formed can facilitate wiring for partition control.

[0137] The order in which each partition enters the atomized state can also be set according to actual conditions. To improve the user experience, atomization control can be performed on a partition-by-partition basis according to the layout, or the partitions can be grouped and atomized according to the layout (even all blocks can be divided into a single group for synchronous control). For example, when a single lens is divided into an inner ring partition and several outer ring partitions that surround each other through a nested approach, when entering the atomized state, the control can be implemented by gradually atomizing from the outer ring partition to the inner ring partition; correspondingly, when entering the transparent state, the control can be implemented by gradually transparentizing from the inner ring partition to the outer ring partition. For another example, when several independent partitions are formed on a single lens through a block approach, when entering the atomized state, the control can be implemented by gradually atomizing from left to right / top to bottom / outer ring block to inner ring block; correspondingly, when entering the transparent state, the control can be implemented by gradually atomizing from right to left / bottom to top / inner ring block to outer ring block, etc. In addition, in actual applications, it is also possible to choose to atomize only some of the partitions, and then wire the control to the partitions that need to be atomized. The time for each partition to gradually enter the fog state from the transparent state and the time for gradually entering the transparent state from the fog state can also be adjusted according to actual conditions, such as 4s, 5s, 7s or even more. In order to improve the user experience, the time for gradually entering the transparent state from the fog state can be designed to be shorter than the time for gradually entering the fog state from the transparent state.

[0138] In another embodiment, the process of controlling the fogging state of each partition in the PNLC partition lens according to the distance parameter sensed by the distance sensing module also includes: determining whether the distance parameter sensed by the distance sensing module is less than a preset distance threshold; if not, controlling each partition to restore to full transparency within a second preset time threshold.

[0139] In this embodiment, the main control module controls each partition to enter the atomization process, and the distance sensing module continuously detects the distance between the configuration direction and the target object and determines whether the distance is still too close. If it is determined to be in a normal state, the main control module controls each partition to restore to full transparency within a second preset time threshold (such as 1s, 2s, etc.) to prevent misjudgment.

[0140] In another embodiment, controlling the fogging state of each partition in the PNLC partitioned lens according to the tilt parameter sensed by the sitting posture sensing module includes: determining whether the tilt parameter sensed by the sitting posture sensing module is greater than a preset tilt threshold; if so, determining that the current sitting posture is improper; determining whether the duration of the improper sitting posture is greater than a first preset time threshold; if so, controlling each partition to enter the fogging state according to preset rules, the preset rules including the division rules of the PNLC partitioned lens for independent partitioning, the order in which each partition enters the fogging state under different division rules, and the fog change time. The independent partitions of the PNLC partitioned lens can also be divided according to actual application requirements. Any scheme that achieves the purpose of preventing and controlling poor eye use by partitioning the lens and then further controlling the fogging state of each partition through the PNLC in the lens is included in this embodiment, such as dividing a single lens into an inner circle partition and several outer circle partitions (the outer circle can be 0, in which case the entire lens is regarded as an inner circle partition) as mentioned above; for example, dividing a single lens into four partitions: upper left, upper right, lower left, and lower right. In practical applications, in order to facilitate the wiring of the common end of each partition and to be more ergonomic, a single lens can be divided into 1-4 circular partitions, especially divided into Figure 2 The four partitions shown, including one inner ring partition and three outer ring partitions, facilitate the purpose of gradually fogging or gradually becoming transparent from the outer ring to the inner ring. The order and time for each partition to enter the fog state can also be set according to actual conditions. For example, in one example, a single lens includes one inner ring partition and one outer ring partition. Then, during the fogging process, fogging begins from the outer ring to the inner ring, and the inner ring starts fogging 2 seconds after the outer ring starts fogging. It takes 7 seconds for both the inner and outer rings to be completely fogged. The above-mentioned preset tilt threshold can be set according to actual conditions, such as 15°, 20°, or even larger. The first preset time threshold can be set according to actual conditions, such as 3s, 4s, or even more. In actual applications, the sitting posture sensing module can be a gyroscope, an angle sensor, or the like.

[0141] In another embodiment, the process of controlling the fogging state of each partition in the PNLC partitioned lens according to the tilt parameter sensed by the sitting posture sensing module also includes: determining whether the tilt parameter sensed by the sitting posture sensing module is greater than a preset tilt threshold; if so, controlling each partition to restore to full transparency within a second preset time threshold.

[0142] In this embodiment, the main control module controls each partition to enter the atomization process, and the sitting posture sensing module continuously detects the wearer's tilt parameters and determines whether the wearer is still in an improper sitting posture. If it is determined to be in a normal state, the main control module controls each partition to restore to full transparency within a second preset time threshold (such as 1s, 2s, etc.) to prevent misjudgment.

[0143] In another embodiment, before obtaining the bad eye use prevention and control parameters sensed by the bad eye use prevention and control parameter sensing module, the method includes: receiving the opening and closing state of the temples sensed by the temple state sensing module, the temple state sensing module being configured in the temples and connected to the main control module; controlling the on and off state of the bad eye use prevention and control function of the glasses according to the opening and closing state of the temples;

[0144] In this embodiment, the temple state sensing module disposed within the first or second temple is used to sense whether the temple is in an unfolded or folded state. When the temple is detected to have transitioned from a folded state to an unfolded state, the glasses' improper eye use prevention and control function is activated, i.e., the glasses enter an on state. When the temple is detected to have transitioned from an unfolded state to a folded state, the glasses' improper eye use prevention and control function is deactivated, i.e., the glasses enter an off state. The temple state sensing module can be of various types, such as one or more of a Hall sensor, a gyroscope, and an angle sensor (sensing angle change data), and can determine the temple's open or closed state by sensing relevant temple data. In one example, the temple state sensing module is a Hall sensor. To achieve the sensing purpose, a Hall sensor can be set on one of the temples and a magnet can be set on the other temple. In this way, when the first temple and the second temple are in a folded state, the distance between the Hall sensor and the magnet is close, and the induced magnetic field strength is large (greater than a preset magnetic field strength threshold); when the first temple and the second temple are in an unfolded state, the distance between the Hall sensor and the magnet is far, and the induced magnetic field strength is small (not greater than a preset magnetic field strength threshold), so that the opening and closing state of the temple is determined according to the magnetic field strength induced by the Hall sensor.

[0145] In another embodiment, before obtaining the improper eye use prevention and control parameters sensed by the improper eye use prevention and control parameter sensing module, it includes: receiving the glasses wearing status sensed by the wearing status sensing module, the wearing status sensing module is configured on the frame body or the inner side of the temple; controlling the working status of the improper eye use prevention and control function according to the wearing status of the glasses.

[0146] In this embodiment, the wearing state sensing module is used to sense whether the user is wearing the glasses for preventing and controlling bad eyesight. When it is detected that the user is wearing glasses, it enters the "working" state, and the main control module controls the bad eyesight prevention and control parameter sensing module to start working; when it is detected that the user takes off the glasses, it enters the "standby" state, and the main control module controls the bad eyesight prevention and control parameter sensing module to start sleeping, thereby realizing intelligent control of the working state of the entire system. In actual applications, the wearing state sensing module can be an infrared sensor. When the user wears glasses, the infrared sensor receives the reflected infrared light to realize intelligent detection of the wearing state of the glasses. In other examples, the wearing state sensing module can also be other forms of sensing modules, such as a gravity sensing module (which achieves the purpose by sensing the change of gravity acceleration), etc. There is no specific limitation here, as long as the purpose of the invention can be achieved.

[0147] In another embodiment, the control method for glasses for preventing and controlling improper eye use further includes: connecting with an external smart terminal through a wireless communication module; receiving multimedia files sent by the external smart terminal and playing them through a speaker module, or performing voice transmission with the external smart terminal and playing them through the speaker module.

[0148] In this embodiment, multimedia files are played through the speaker module, including playing a "wearing detection prompt tone" after detecting that the user is wearing glasses, playing music files, learning course audio files, etc.; the speaker module is also used for the glasses to play voice when making a voice call with an external intelligent terminal. The position of the speaker in the first temple and / or the second temple can be adjusted according to actual conditions, close to the user's ear, so that the user can receive the files it plays. In order to save resources, when it is detected that the user takes off the glasses, the main control module controls the speaker module to stop playing. The wireless communication module is used to interact with the outside world for data, including receiving control information, uploading sensing parameters, etc., and can be a wifi module, a bluetooth module, an infrared module, etc.

[0149] In one example, the wireless communication module is a Bluetooth module, which works with a speaker module to realize the functions of a Bluetooth headset and the transmission of multimedia files and call voice. The Bluetooth module can be connected to an external smart terminal independently through a normal connection or through an APP. Among them, the normal connection is used for users (children) to listen to music, take online classes, and answer calls on a daily basis, such as connecting to a smart terminal such as a learning machine that is also equipped with a Bluetooth module. The APP connection is used for parents to obtain information such as their children's eye data through a mobile phone APP via a BLE connection.

[0150] During the first pairing process, turn on the Bluetooth function of the glasses and the smart terminal at the same time, search for the device name and complete the pairing and connect directly; or follow the instructions in the APP, search for the device name, click to complete the pairing and connect directly.
