[0002] With increasing awareness of vision protection, eye massagers, as external therapeutic devices that use low-intensity laser light to irradiate the eyes, have been widely used in the field of vision care. Traditional eye massagers are mainly designed based on red lasers. By irradiating the eyes with low-intensity red light, they improve microcirculation in the fundus and stimulate the retina to secrete dopamine to regulate the eye's axis, thereby controlling vision. However, current red light eye massagers have many problems: uncontrolled light power may cause burns to the user's fundus; uneven light power distribution can easily cause fundus damage; at the same time, red light can also easily cause psychological panic among buyers, affecting product sales.

[0003] Existing eye massagers often require prolonged wear with a fixed strap for extended periods of multi-frequency biophoton irradiation therapy. This method can easily cause eye fatigue, eye burning, excessive tear production, and other discomforts, affecting the user experience. Furthermore, conventional eye massagers often lack sufficient artificial light source frequencies or have insufficient frequency abundance, resulting in poor light therapy effects on the eyes.

[0004] Therefore, there is an urgent need to develop a new type of eye care device that can effectively avoid the drawbacks of red light eye care devices while meeting the needs of users with different vision conditions. At the same time, the product should also be portable, safe, and comfortable to improve the user experience. Utility Model Content

It can be a lens with a specific curvature made of optical grade resin or glass material, used to realize the convergence, divergence or parallel transmission of light. The symmetrical arrangement means that the two sets of light-transmitting lenses 51 are arranged on the left and right sides respectively with the vertical central axis of the front shell 11 as the reference and have the same structure and optical parameters. This symmetrical structure design aims to ensure that the light characteristics received by the left and right eyes are consistent, providing a balanced optical environment for binocular vision. This is crucial for achieving a uniform visual experience and coordinated eye accommodation, and meets the basic requirement of the eye protection device to perform synchronous and consistent optical processing on the left and right eyes.

[0040] In this embodiment, the use of symmetrically arranged light-transmitting modules 5 provides balanced and stable optical performance for the eye protection device. The symmetrical layout of the two sets of light-transmitting lenses 51, based on the vertical central axis of the front shell 11, ensures that the light received by the left and right eyes is completely consistent in optical characteristics. This symmetrical structure creates a balanced optical environment for the user's binocular vision, effectively eliminating visual discomfort that may be caused by differences in light received by the left and right eyes. This design ensures that both eyes can obtain a uniform visual experience and promotes the coordination of eye accommodation, which plays an important role in maintaining visual comfort and achieving effective eye protection functions, fully meeting the basic requirement of the eye protection device to perform synchronous and consistent optical processing for both eyes.

[0041] Furthermore, in some embodiments, the two sets of light-transmitting mirrors 51 of the light-transmitting module 5 are plano-convex lenses.

[0042] In this embodiment, a plano-convex lens refers to a common optical lens, characterized by one optical surface being a complete plane and the other being an outwardly convex spherical surface. This type of lens can be precisely manufactured from light-transmitting materials such as optical glass or polymers, and is used to converge passing light. When two sets of plano-convex lenses are symmetrically arranged in the light-transmitting module 5, each lens corresponds to one of the user's eyes. This configuration provides both eyes with consistent imaging characteristics, ensuring the coordination and synchronization of light transmission. Its symmetrical optical structure forms an important foundation for maintaining visual balance, achieving coordinated eye accommodation, and obtaining a comfortable visual experience.

[0043] In this embodiment, a plano-convex lens is used as the core optical element of the light-transmitting module 5, bringing significant advantages to the eye massager through its unique optical characteristics. One optical surface of the plano-convex lens is flat, and the other is a convex spherical surface; this structure gives it excellent light-convexity. When the two sets of plano-convex lenses are symmetrically arranged, they provide the user's two eyes with completely consistent imaging effects. This configuration ensures that the light received by the left and right eyes maintains a high degree of coordination and synchronization during transmission, establishing a balanced optical foundation for binocular vision. The symmetrical optical structure effectively maintains the balance of the visual system, promotes the coordinated operation of the eye's accommodation mechanism, and thus creates a more comfortable and natural visual experience for the user, which plays a crucial supporting role in realizing the basic functions of the eye massager.

[0044] Furthermore, in some embodiments, the color-changing film assembly 7 is provided in two sets, with each set of the color-changing film assembly 7 corresponding to one of the two sets of light-transmitting lenses 51.

[0045] In this embodiment, the photochromic film assembly 7 refers to a complete functional unit composed of the photochromic film 71 and its driving circuit. The photochromic film 71 is a functional thin film capable of changing its light transmission characteristics under the action of an applied electric field, and the driving circuit is an electronic control circuit that provides a specific voltage signal to the photochromic film 71. The two-set configuration refers to two independent and structurally identical photochromic film assemblies 7 arranged symmetrically with the vertical central axis of the front shell 11 as a reference. The light-transmitting lens 51 refers to the optical lens constituting the core of the light-transmitting module 5. The correspondence means that each photochromic film assembly 7 is precisely matched with a light-transmitting lens 51 in the optical path, forming an independent optical adjustment channel. This one-to-one correspondence configuration allows each photochromic film assembly 7 to independently control the light transmission characteristics of its corresponding light-transmitting lens 51, providing the necessary structural basis for independent adjustment of the optical path parameters of the left and right eyes, and ensuring the consistency and coordination of binocular visual experience.

[0046] In this embodiment, by setting two sets of photochromic film assemblies 7 corresponding to the light-transmitting lenses 51 respectively, independent and precise control of the optical path parameters for the left and right eyes is achieved. Each photochromic film assembly 7 and its corresponding light-transmitting lens 51 form an independent optical adjustment channel, allowing the light transmission characteristics of each eye to be adjusted separately according to their respective needs. This one-to-one correspondence provides a structural basis for personalized visual adjustment, ensuring both consistency of visual experience for both eyes and coordination of optical processing. The independent adjustment channels enable the eye massager to adapt to different visual conditions of the user's eyes, while maintaining the balance and comfort of binocular vision, effectively improving the flexibility and adaptability of the eye massager and providing a more precise and comfortable optical adjustment experience for different users.

[0047] Furthermore, in some embodiments, the housing assembly 1 is made of plastic, and the first support leg 2 and the second support leg 3 are made of metal.

They are made of metal and can be manufactured using die casting or machining processes. They provide a stable mounting base and structural support for core components such as the control board and the light-transmitting module 5. The use of plastic for the outer shell assembly 1 helps reduce overall weight and improve design flexibility, while the use of metal for the first support leg 2 and the second support leg 3 ensures overall structural rigidity and long-term stability. This combination of materials achieves an optimized weight balance while ensuring product structural strength, meeting both portability requirements and ensuring accurate positioning of internal precision components.

[0049] In this embodiment, the overall performance of the eye massager is optimized and improved by combining the outer shell assembly 1 (made of plastic) with the first support leg 2 and the second support leg 3 (made of metal). The plastic outer shell assembly 1 not only effectively reduces the overall weight of the product but also provides good design flexibility while fully ensuring the containment and protection of the internal optical and electronic components. The metal first support leg 2 and the second support leg 3 provide reliable structural rigidity and a stable support foundation for the eye massager, ensuring that core components such as the control board and the light-transmitting module 5 maintain precise installation and positioning during long-term use. This material combination scheme allows the product to meet portability requirements while taking into account structural strength and operational stability, optimizing the user's holding experience and ensuring the long-term reliability of the internal precision optical system.

[0050] Furthermore, in some embodiments, the light sensing device 9 employs a photodiode.

[0051] In this embodiment, the light-sensing device 9 refers to an optical detection device installed at the front end of the housing, used to sense the ambient light intensity in real time.

In the eye protection device, the photodiode serves as the core photosensitive element, used to accurately detect the ambient light level and convert the light signal into a corresponding electrical signal, which is then transmitted to the control board. This photoelectric conversion mechanism provides accurate ambient light intensity data for the intelligent light control system of the eye protection device, enabling the control board to precisely adjust the light transmission state of the color-changing film 71 according to actual lighting conditions, thereby achieving adaptive management of incoming light, ensuring visual comfort, and improving the eye protection effect.

[0052] In this embodiment, a photodiode is used as the core component of the light sensor 9, significantly improving the eye protector's perception accuracy and response capability to ambient light. Based on the photoelectric conversion characteristics of a semiconductor PN junction, the photodiode can accurately convert ambient light intensity into a corresponding electrical signal, providing a reliable data foundation for the control board. This precise light intensity detection mechanism allows the eye protector to sense changes in ambient light in real time and adjust the light transmittance of the color-changing film 71 promptly through the control board.

The temperature sensor is a sensing element within the electrical sensing component 10 specifically designed to detect temperature changes. It is installed inside the second support leg 3 and positioned close to the battery 6 to monitor temperature changes in the battery 6 during operation. The thermistor is a semiconductor element whose resistance changes significantly with temperature; it can be a negative temperature coefficient thermistor, where its resistance decreases as the ambient temperature rises. This temperature-sensitive characteristic allows the thermistor to convert temperature changes into an accurate resistance signal, which is transmitted to the control board for real-time processing, providing reliable temperature data support for the eye protection device's thermal management system, thereby ensuring stable operation of the device within a safe temperature range.

[0055] In this embodiment, a thermistor is used as the temperature sensor in the electrical sensing component 10, establishing a reliable thermal management foundation for the eye protection device. The thermistor, with its sensitive resistance changing with temperature, can accurately monitor the temperature changes of the battery 6 during operation and convert these changes into accurate resistance signals transmitted to the control board. This real-time temperature monitoring mechanism allows the eye protection device to promptly grasp the thermal state of the battery 6, providing crucial data support for the device's thermal management system. Based on this real-time temperature data, the eye protection device can implement corresponding thermal management strategies, ensuring that all components operate within a safe temperature range, effectively preventing equipment failures caused by abnormal temperatures, and thus significantly improving the stability and safety of product use.
