[0002] In recent years, with breakthroughs and developments in science and technology, and the increasingly diversified demands of people's lifestyles and entertainment needs, smart wearable and VR wearable devices have ushered in unprecedented development opportunities, resulting in a growing variety of products. Among them, VR devices are seeing more and more application scenarios and their technology is becoming increasingly mature. It is expected that VR products will experience explosive growth in the near future. Based on VR devices, wearable glasses have emerged. Due to their small size, thin and light structure, and powerful functions, more and more companies are developing related products. However, in this technology, wearable glasses have relatively limited functionality, especially in situations where light intensity changes drastically, failing to take appropriate measures to ensure the wearer's safety. Summary of the Invention

[0003] One object of this disclosure is to provide an eyewear device, a safety assistance system, a method and apparatus for eyewear safety.

[0004] According to a first aspect of this disclosure, a glasses safety assistance system is provided, the system comprising:

[0005] A lens, the light transmittance of which is variable;

[0006] A camera is used to capture image information around the glasses;

[0007] A photosensor is used to collect information about the light intensity around the glasses; and

[0008] The control module is used to receive the image information and the light intensity information, and control the lens according to the image information and the light intensity information.

[0009] Specifically, when the control module determines, based on the light intensity information, that the change in light intensity around the glasses exceeds a predetermined threshold, it changes the light transmittance of the lens based on the image information.

[0010] Optionally, the control module determines, based on the light intensity information, that when the increase in light intensity around the glasses exceeds a first predetermined threshold, it reduces the light transmittance of the lens based on the image information; or,

[0011] The control module determines, based on the light intensity information, that when the decrease in light intensity around the glasses exceeds a second predetermined threshold, that the light transmittance of the lens is increased based on the image information.

[0012] Optionally, the image information includes a target image of the target object.

[0013] Specifically, the control module determines, based on the light intensity information, that when the change in light intensity around the glasses exceeds a predetermined threshold, it changes the light transmittance of the lens so that the light transmittance of the portion of the lens corresponding to the target image is greater than or less than the light transmittance of other portions.

[0014] Optionally, when the control module determines the target object based on the image information, it controls the lens to display a prompt message.

[0015] Optionally, the control module includes a computing unit and a reminder unit.

[0016] The calculation unit determines the target object based on the image information and instructs the reminder unit to issue a first reminder message based on the condition of the target object.

[0017] Optionally, where, if the target object is a lane, the calculation unit determines a first position of the lane relative to the glasses based on the image information, and if the first position indicates that the glasses are deviating from the lane, instructs the alerting unit to issue the first alert message; and / or,

[0018] In the case where the target object is a vehicle or a pedestrian, the calculation unit determines the second position of the vehicle or pedestrian relative to the glasses based on the image information, and if the second position is within a dangerous distance range, instructs the reminder unit to issue the first reminder information.

[0019] Optionally, the image information includes information about the target object, and the changed transmittance is determined based on the light intensity of the target object.

[0020] According to a second aspect of this disclosure, an eyeglass device is provided, comprising:

[0021] Eyeglass frames;

[0022] Based on the eyewear safety assistance system described in the first aspect above

[0023] The lens, camera, and photosensor are mounted on the eyeglass frame.

[0024] The control module is located on the frame or outside the frame, or part of the control module is located on the frame and another part is located outside the frame.

[0025] Optionally, the eyewear device includes a first frame and a second frame, with the lenses, camera, and photosensor disposed on the first frame.

[0026] When the first frame is in the wearing state, the control module determines that the change in light intensity around the glasses is less than or equal to a predetermined threshold based on the light intensity information around the glasses collected by the photosensitive sensor, and determines that the target object is not included based on the image information around the glasses collected by the camera. Then, the control reminder unit issues a second reminder message. The second reminder message is used to remind the wearer to switch the first frame to the second frame.

[0027] According to a third aspect of this disclosure, a method for eyeglass safety is provided, applied to the eyeglass safety assist system described in the first aspect above, wherein the method includes:

[0028] Acquire image information around the glasses;

[0029] Collect light intensity information around the glasses;

[0030] When the change in light intensity around the glasses is greater than a predetermined threshold based on the light intensity information, the light transmittance of the lens is changed based on the image information.

[0031] Optionally, the light intensity information includes first light intensity information behind the glasses and second light intensity information in front of the glasses.

[0032] When the change in light intensity around the glasses is determined to be greater than a predetermined threshold based on the light intensity information, the light transmittance of the lens is changed based on the image information, including:

[0033] When the first light intensity information is less than the second light intensity information, and the first difference value between the second light intensity information and the first light intensity information is greater than a first predetermined threshold, the light transmittance of the lens is reduced according to the first difference value and the image information.

[0034] When the first light intensity information is greater than the second light intensity information, and the second difference value between the first light intensity information and the second light intensity information is greater than the second predetermined threshold, the light transmittance of the lens is increased according to the second difference value and the image information.

[0035] According to a fourth aspect of this disclosure, a device for eyeglass safety is provided, applied to the eyeglass safety assistance system described in the first aspect above, wherein the device comprises:

[0036] The first acquisition module is used to acquire image information around the glasses;

[0037] The second acquisition module is used to acquire light intensity information around the glasses;

[0038] The determination module is used to change the light transmittance of the lens based on the image information when the change in light intensity around the glasses is greater than a predetermined threshold, based on the light intensity information.

The camera is used to collect image information around the glasses, the photosensor is used to collect light intensity information around the glasses, and the control module is used to change the light transmittance of the lens based on the image information when it determines that the change in light intensity around the glasses exceeds a predetermined threshold. That is, when the light intensity information collected by the photosensor determines that the change in light intensity around the glasses exceeds a predetermined threshold and affects the wearer's ability to see, the eyewear safety assistance system will change the light transmittance of the lens based on the image information collected by the camera to control the light intensity around the glasses within a suitable range, thereby ensuring the wearer's safety.

[0051] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0052] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0053] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0054] <System Implementation Example>

[0055] Figure 1 This is a block diagram of the hardware configuration of the glasses safety assistance system 10 according to an embodiment of the present disclosure. (Refer to...) Figure 1 As shown, the glasses safety assistance system 10 includes a lens 110, a camera 120, a photosensor 130, and a control module 140. (Referring to...) Figure 3 As shown, the lens 110, camera 120, and photosensor 130 are integrated on the frame 20 of the glasses.

[0056] The light transmittance of the lens 110 is variable. The lens 110 can be made directly from electrochromic glass, or an electrochromic film can be directly attached to the lens 110.

[0057] Among them, the photosensitive sensor 130 is used to collect information on the light intensity around the glasses.

[0058] The camera 120 is used to collect image information around the glasses. Specifically, the camera 120 can collect image information of the environment within the field of view in front of the glasses wearer.

[0059] The control module 140 receives image information and light intensity information, and controls the lens 110 based on the image information and light intensity information. Specifically, when the change in light intensity around the glasses exceeds a predetermined threshold based on the light intensity information, the control module 140 changes the light transmittance of the lens 110 based on the image information.

[0060] In this embodiment, the changes in ambient light intensity around the glasses can be monitored in real time using a photosensor 130. Under normal circumstances, the human eye has a maximum threshold of light intensity that it can tolerate. Exceeding this threshold makes it difficult for the eye to see objects in the environment normally, or causes extreme eye discomfort. Electrochromic glass or electrochromic film is a novel material whose optical properties can undergo stable and reversible color changes under the influence of an external electric field. This manifests as reversible changes in color and transparency, allowing the fabrication of a lens 110 whose transmittance changes with ambient light intensity.

[0061] In this embodiment, the camera 120 can capture image information around the glasses, including information about the target object. The target object is typically anything that may pose a danger to the glasses wearer, such as, but not limited to, lanes, vehicles, or pedestrians. In real-world scenarios, when the glasses deviate from the lane, it indicates a potential threat to the wearer's safety; conversely, when a vehicle or pedestrian gets closer to the glasses, it indicates a possible threat to the wearer's safety.

[0062] In one specific embodiment, when the change in light intensity around the glasses exceeds a predetermined threshold and the image information includes information about the target object, the control module 140 will change the light transmittance of the lens 110 so that the light intensity transmitted through the lens 110 is within the range acceptable to the human eye, ensuring that the light intensity that the human eye can receive does not change too much, thus ensuring driving safety.

[0063] In this embodiment, the eyewear safety assistance system includes a lens made of electrochromic glass, a camera, a photosensor, and a control module. The camera is used to acquire image information about the area around the glasses, the photosensor is used to acquire light intensity information about the area around the glasses, and the control module is used to adjust the light transmittance of the lens based on the image information when the change in light intensity around the glasses exceeds a predetermined threshold. That is, when the light intensity information acquired by the photosensor determines that the change in light intensity around the glasses exceeds a predetermined threshold and affects the wearer's visual ability, the eyewear safety assistance system will adjust the light transmittance of the lens based on the image information acquired by the camera to control the light intensity around the glasses within a suitable range, thereby ensuring the safety of the eyewear wearer.

[0064] In one embodiment, when the control module 140 determines, based on the light intensity information, that the increase in light intensity around the glasses is greater than a first predetermined threshold, it reduces the light transmittance of the lens 110 based on the image information.

[0065] The first preset threshold can be a value set according to the actual application scenario and actual use. When the increase in light intensity around the glasses exceeds the first preset threshold, it indicates that the light intensity has increased drastically, affecting the human eye's observation ability. At this time, if the image information includes information about the target object, the light transmittance of the lens is reduced to control the light intensity within a suitable range.

[0066] In a specific scenario, such as when a driver encounters oncoming high beams, experiences strong glare due to mirror reflection at night, or experiences a sudden increase in ambient light upon exiting a tunnel during the day—that is, when the increase in light intensity around the glasses exceeds a first predetermined threshold—the control module 140 can instantly reduce the lens transmittance. This addresses situations where the light intensity around the glasses increases beyond a predetermined threshold. Simultaneously, the camera 120 can capture image information about the area around the glasses. When the image information contains information about the target object, and the increase in light intensity around the glasses exceeds the first predetermined threshold, the control module 140 can instantly reduce the lens transmittance. On one hand, this protects the wearer from the safety hazards posed by sudden strong light at night or sudden changes in ambient light upon exiting a tunnel during the day, ensuring safety while preventing strong light from irradiating the eyes and protecting eye health. On the other hand, it reduces lens transmittance based on the captured image information about the area around the glasses. If there are hazardous factors in the current environment and the ambient light suddenly increases, the lens transmittance is immediately reduced, thus mitigating driving safety hazards.

[0067] In one embodiment, when the control module 140 determines, based on the light intensity information, that the decrease in light intensity around the glasses is greater than a second predetermined threshold, it increases the light transmittance of the lens 110 based on the image information.

[0068] The second preset threshold can be a value set according to the actual application scenario and actual use. When the decrease in light intensity around the glasses is greater than the second preset threshold, it indicates that the light intensity has decreased drastically, affecting the human eye's observation ability. At this time, if the image information includes information about the target object, the transmittance of the lens is increased to control the light intensity within a suitable range.

[0069] In a specific scenario, such as when a wearer is driving during the day and suddenly enters a tunnel, the ambient light suddenly decreases—that is, the decrease in light intensity around the glasses exceeds a second predetermined threshold. Simultaneously, camera 120 can capture image information around the glasses. When the image information contains information about a target object and the light intensity drops drastically, control module 140 can instantly increase the lens transmittance. This greatly mitigates the safety hazards caused by sudden changes in ambient light when entering a tunnel during the day. Furthermore, by increasing lens transmittance based on the captured image information around the glasses, if there are hazardous factors in the current environment and the ambient light suddenly decreases, the immediate increase in lens transmittance reduces safety risks while driving.

[0070] In one embodiment, the image information includes information about the target object, and the altered transmittance is determined based on the light intensity of the target object.

[0071] In this embodiment, when the change in light intensity around the glasses is greater than a predetermined threshold and the image information includes information about the target object, the control module 140 can change the light intensity of the target object based on the light intensity of the target object, so that the target object can be most prominent.

[0072] In a specific scenario, such as when a wearer is driving during the day and the ambient light suddenly decreases while entering a tunnel, posing a danger to driving, the light transmittance of the lens can be increased based on the light intensity of the target object in the image information. This can protect the wearer from the safety hazards caused by the sudden increase in ambient light when entering a tunnel during the day.

[0073] In specific scenarios, such as when a driver encounters oncoming high beams, experiences strong light due to mirror reflection at night, or experiences a sudden increase in ambient light when exiting a tunnel during the day, the lens transmittance can be reduced based on the light intensity of the target object in the image information. This ensures the wearer's safety when encountering sudden strong light at night or when the ambient light changes abruptly when exiting a tunnel during the day, thus protecting their eyes from strong light and safeguarding their eye health.

[0074] In one embodiment, the image information includes a target image of the target object.

[0075] The control module 140 determines, based on the light intensity information, that when the change in light intensity around the glasses exceeds a predetermined threshold, the light transmittance of the lens 110 is adjusted so that the light transmittance of the portion of the lens 110 corresponding to the target image is greater than or less than the light transmittance of other portions. In other words, the light transmittance varies in different areas of the lens 110, which highlights the target object. This protects the wearer's eyes while also making it easier for the wearer to observe the object.

[0076] In one example, when the increase in light intensity around the glasses exceeds a first predetermined threshold based on light intensity information, and the image information contains an image of the target object, to avoid directly reducing the lens transmittance and thus affecting the wearer's observation of the target object, this example reduces the overall lens transmittance while ensuring that the transmittance of the portion of the lens corresponding to the target image is greater than that of other portions. This protects the wearer's glasses while allowing them to clearly observe the target object, thereby ensuring driving safety.

[0077] In one example, when the decrease in light intensity around the glasses is determined to be greater than a second predetermined threshold based on light intensity information, and the image information contains an image of the target object, to avoid directly increasing the lens transmittance and thus affecting the wearer's observation of the target object, this example increases the overall transmittance of the lens while ensuring that the transmittance of the portion of the lens corresponding to the target image is lower than that of other portions.

[0078] In one embodiment, when the control module 140 determines the target object based on the image information, it controls the lens 110 to display a prompt message.

[0079] In this embodiment, when the control module 140 determines the lane, vehicle or pedestrian based on the image information, it controls the lens 110 to display the lane, vehicle or pedestrian, thereby enabling the wearer to track the lane, vehicle or pedestrian in real time.

[0080] In one embodiment, refer to Figure 2 The control module 140 includes a calculation unit 141 and an alert unit 142. The calculation unit 141 determines the target object based on the image information and instructs the alert unit 142 to issue a first alert message based on the condition of the target object.

[0081] In one example, when the target object is a lane, the calculation unit 141 determines a first position of the lane relative to the glasses based on the image information, and if the first position indicates that the glasses are deviating from the lane, instructs the reminder unit 142 to issue the first reminder information.

[0082] In a specific scenario, when the target object is a lane, the calculation unit 141 locks onto the lane trajectory based on image information and calculates the lane's initial position relative to the glasses in real time. If the initial position indicates that the glasses are deviating from the lane, a dangerous lane departure situation may occur at any time. In this case, the calculation unit 141 instructs the warning unit 142 to issue a first warning message. For example, the warning unit 142 can be a horn, which can emit a warning sound. Alternatively, the warning unit 142 can be a warning light, connected to the vehicle control system via Bluetooth. By sending a signal to the vehicle control system to reduce vehicle speed and activate the vehicle's warning lights, it ensures vehicle safety while reminding following vehicles to slow down and avoid the area.

[0083] In one example, when the target object is a vehicle or a pedestrian, the calculation unit 141 determines the second position of the vehicle or pedestrian relative to the glasses based on the image information, and if the second position is within a dangerous distance range, instructs the alert unit 142 to issue the first alert information.

[0084] In a specific scenario, when the target object is a vehicle or pedestrian, the calculation unit 141 determines the second position of the vehicle or pedestrian relative to the glasses based on image information. If the second position is within a danger distance, it instructs the alert unit 142 to issue a first alert. For example, the alert unit 142 can be a horn, which can emit a warning sound. Alternatively, the alert unit 141 can be a warning light, connected to the vehicle control system via Bluetooth. By sending a signal to the vehicle control system to reduce vehicle speed and activate the vehicle warning light, it ensures vehicle safety while alerting following vehicles to slow down and avoid the vehicle.

[0085] <Equipment Example>

[0086] Figure 4 This is a structural schematic diagram of an eyeglass device according to one embodiment. (See diagram below.) Figure 4 As shown, the eyewear device 400 includes a frame 20 and an eyewear safety assistance system 10.

[0087] Among them, such as Figure 3 As shown, the lens 110, camera 120 and photosensor 130 are mounted on the frame 20.

[0088] The control module 140 is located on the frame 20 or outside the frame 20, or a portion of the control module 140 is located on the frame 20 and another portion is located outside the frame 20.

[0089] According to an embodiment of this disclosure, a glasses safety assistance system includes a lens made of electrochromic glass, a camera, a photosensor, and a control module. The camera is used to acquire image information about the area around the glasses, the photosensor is used to acquire light intensity information about the area around the glasses, and the control module is used to change the light transmittance of the lens based on the image information when the change in light intensity around the glasses exceeds a predetermined threshold. That is, when the light intensity information acquired by the photosensor determines that the change in light intensity around the glasses exceeds a predetermined threshold and affects the wearer's ability to see, the glasses safety assistance system will change the light transmittance of the lens based on the image information acquired by the camera to control the light intensity around the glasses within a suitable range, thereby ensuring the wearer's safety.

[0090] In one embodiment, the eyewear device 400 includes a first frame and a second frame (both shown in the figure), and the lens 110, camera 120 and photosensor 130 are disposed on the first frame.

[0091] In this embodiment, when the first frame is being worn, the control module 140 determines, based on the light intensity information around the glasses collected by the photosensitive sensor 130, that the change in light intensity around the glasses is less than or equal to a predetermined threshold, and determines, based on the image information around the glasses collected by the camera 120, that the target object is not included, that the control reminder unit issues a second reminder message; wherein, the second reminder message is used to remind the wearer to switch the first frame to the second frame.

[0092] In a specific scenario, since the lens 110, camera 120, and photosensor 130 are mounted on the first frame, when the wearer is wearing the first frame, the photosensor 130 can detect and collect light intensity information around the glasses, and the camera 120 can collect image information around the glasses. When the change in light intensity around the glasses is less than or equal to a predetermined threshold, the control module 140 indicates that the light intensity around the glasses is relatively stable. At the same time, when the image information does not include the target object, it indicates that there are no dangerous factors around the glasses. At this time, the control module 140 can control the reminder unit to issue a second reminder message. This second reminder message is used to remind the wearer that the current environment is stable and that the first frame can be switched to the second frame to reduce the power consumption of the device.

[0093] In one embodiment, the photosensor 130 may include a first photosensor 131 and a second photosensor 132, wherein the first photosensor 131 is used to collect first light intensity information behind the glasses, and the second photosensor 132 is used to collect second light intensity information in front of the glasses.

[0094] <Method Implementation>

[0095] Figure 5 An embodiment of this disclosure illustrates a method for eyeglass safety, which can be, for example, by... Figure 1 or Figure 2 The eyeglasses safety assistance system 10 shown is implemented.

[0096] like Figure 5 As shown, the method for eyeglass safety provided in this embodiment may include the following steps S5100 to S5300.

[0097] Step S5100: Acquire image information around the glasses.

[0098] In this embodiment, the light intensity information around the glasses can be collected based on the photosensitive sensor 130.

[0099] Step S5200: Collect light intensity information around the glasses.

[0100] In this embodiment, image information of the environment within the field of view in front of the glasses wearer can be collected based on the camera 120.

[0101] Step S5300: When the change in light intensity around the glasses is greater than a predetermined threshold based on the light intensity information, the light transmittance of the lens is changed based on the image information.

[0102] According to embodiments of this disclosure, when it is determined that the change in the light intensity around the glasses exceeds a predetermined threshold based on the light intensity information of the environment around the glasses, affecting the human eye's observation ability, the transmittance of the lens will be changed based on image information to control the light intensity around the glasses within a suitable range, thereby ensuring the wearer's safety.

[0103] In one embodiment, the light intensity information includes first light intensity information behind the glasses and second light intensity information in front of the glasses.

[0104] In this embodiment, step S5300 above, where it is determined based on the light intensity information that the change in light intensity around the glasses is greater than a predetermined threshold, and the light transmittance of the lens is changed based on the image information, may further include:

[0105] When the first light intensity information is less than the second light intensity information, and the first difference value between the second light intensity information and the first light intensity information is greater than a first predetermined threshold, the light transmittance of the lens is reduced according to the first difference value and the image information.

[0106] In a specific scenario, such as when a wearer is driving and the ambient light suddenly increases as they exit a tunnel, causing the first light intensity information behind the glasses to be much less than the second light intensity information in front of the glasses, if the image information includes a target object, the control module 140 needs to reduce the light transmittance of the lens based on the first difference value between the two.

[0107] When the first light intensity information is greater than the second light intensity information, and the second difference value between the first light intensity information and the second light intensity information is greater than the second predetermined threshold, the light transmittance of the lens is increased according to the second difference value and the image information, so that the light transmittance can be adjusted according to the actual scene, which is more in line with the user's needs.

[0108] In a specific scenario, such as when a wearer is driving and the ambient light suddenly decreases as they enter a tunnel, the first light intensity information behind the glasses is much greater than the second light intensity information in front of the glasses. In this case, if the image information includes a target object, the control module 140 needs to increase the light transmittance of the lens based on the second difference value between the two, so that the light transmittance can be adjusted according to the actual scene to better meet the user's needs.

[0109] <Example>

[0110] The following example illustrates a method for eyeglass safety, in which reference is made to... Figure 1 , Figure 6 The method for eyeglass safety may include:

[0111] (1) The control module 140 acquires image information around the glasses captured by the camera 120, and the calculation unit 141 identifies feature points in the image information and matches the feature points with a preset model to determine the target object. If the target object is a lane, the calculation unit 141 will determine the first position of the lane relative to the glasses.

[0112] The control module 140 acquires ambient light intensity information collected by the photosensor 130. When the change in light intensity around the glasses exceeds a predetermined threshold, and the lane position relative to the glasses indicates that the glasses are deviating from the vehicle, an emergency protection mode is activated. This emergency protection mode includes, for example, changing the light transmittance of the lens 110; for example, emitting a warning sound via the alert unit 142, such as a horn; or for example, connecting to the vehicle control system via Bluetooth, sending a signal to the vehicle control system to reduce vehicle speed, and activating the alert unit 142, such as a vehicle warning light, to ensure vehicle safety while alerting following vehicles to slow down and avoid the area.

[0113] The control module 140 acquires ambient light intensity information collected by the photosensor 130. If the change in light intensity around the glasses exceeds a predetermined threshold, and the lane position relative to the glasses indicates that the glasses are not deviating from the vehicle, the control module 140 activates a normal protection mode. For example, it changes the light transmittance of the lens 110.

[0114] The control module 140 acquires ambient light intensity information collected by the photosensor 130. When the change in light intensity around the glasses is less than or equal to a predetermined threshold, and the lane's position relative to the glasses indicates that the glasses are deviating from the vehicle, the warning mode is activated. For example, a warning sound is emitted via the warning unit 142, such as a horn. Alternatively, by connecting to the vehicle control system via Bluetooth, a signal is sent to the vehicle control system to reduce vehicle speed and activate the warning unit 142, such as a vehicle warning light, thus ensuring vehicle safety while alerting following vehicles to slow down and avoid the area.

[0115] (2) If the target object is a vehicle or a pedestrian, it means that a vehicle or pedestrian appears in front of the driver during the driving process, and the calculation unit 141 will determine the second position of the vehicle or pedestrian relative to the glasses.

[0116] The control module 140 acquires ambient light intensity information collected by the photosensor 130. When the change in light intensity around the glasses exceeds a predetermined threshold, and a vehicle or pedestrian is within a dangerous distance relative to the glasses, an emergency protection mode is activated. This emergency protection mode includes, for example, changing the light transmittance of the lens 110; for example, emitting a warning sound via the alert unit 142, such as a horn; or for example, connecting to the vehicle control system via Bluetooth, sending a signal to the vehicle control system to reduce vehicle speed, and activating the alert unit 142, such as a vehicle warning light, to ensure vehicle safety while alerting following vehicles to slow down and avoid the area.

[0117] The control module 140 acquires ambient light intensity information collected by the photosensor 130. If the change in light intensity around the glasses exceeds a predetermined threshold and the second position is not within a dangerous distance range, the control module 140 activates a normal protection mode. For example, it changes the light transmittance of the lens 110.

[0118] The control module 140 acquires ambient light intensity information collected by the photosensor 130. If the change in light intensity around the glasses is less than or equal to a predetermined threshold, and the second position is within a dangerous distance range, the warning mode is activated. For example, a warning sound is emitted via the warning unit 142, such as a horn. Alternatively, by connecting to the vehicle control system via Bluetooth, a signal is sent to the vehicle control system to reduce vehicle speed and activate the warning unit 142, such as a vehicle warning light, thus ensuring vehicle safety while alerting following vehicles to slow down and avoid the area.
