[0002] Myopia is one of the most common ophthalmic diseases globally and is expected to affect nearly 50% of the global population by 2050. Although existing optical, pharmacological, and behavioral intervention measures can control myopia progression to a certain extent, their specific mechanisms are still not fully understood.

[0003] In recent years, stress events prevalent in the educational environment have been found to be causally related to the high incidence of myopia. These events may cause psychological stress, which in turn affects the ocular structure and function through the autonomic nervous system.

[0004] Existing myopia control technologies mainly focus on optical correction, pharmacological treatment, and behavioral intervention. However, the effects of these methods are limited and cannot fundamentally solve the problem of myopia progression. In addition, the impact of psychological stress on the ocular structure has not been fully studied, and there is a lack of effective technical means to intervene in this process. Summary of the Invention

[0027] Figure 3 FIG. is a schematic structural diagram of another angle of a multifunctional glasses for controlling the progression of myopia provided by an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical content of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] The core concept of the embodiment of the present invention is: by applying specific electrical stimulation to the cymba conchae area (specifically, the vagus nerve in the cymba conchae), improving the regulation of the autonomic nervous system on the eyes, reducing the negative impact of psychological stress on the eye structure, thereby effectively increasing the choroid thickness and slowing down the elongation speed of the eye axis, and providing a safe and effective means for myopia control.

[0030] As Figure 1 shown, a multifunctional glasses for controlling the progression of myopia provided by an embodiment of the present invention includes a frame 1, two temple arms 2, two lenses 3, a control chip 4, two stimulators 5 and two eye trackers 6. Among them, the control chip 4 is arranged on the frame 1. The two stimulators 5 are respectively arranged on the two temple arms 2 and are electrically connected to the control chip 4 for applying specific electrical stimulation to the cymba conchae area. The two eye trackers 6 are respectively arranged on the two lenses 3 and are electrically connected to the control chip 4 for collecting eye movement data. Thus, in specific use, the control chip 4 controls the stimulator 5 to emit a preset electrical stimulation to the vagus nerve area of the ear; and, the eye tracker 6 is controlled to collect eye movement data to adjust the stimulation frequency of the stimulator 5 based on the eye movement data.

[0031] As Figure 1 shown, in this embodiment, a concave portion 11 is formed at the top of the frame 1, the control chip 4 is arranged in the concave portion 11, and a protective cover 12 is provided outside the control chip 4 to ensure the safety of the control chip 4. As Figure 2As shown, in this embodiment, the control chip 4 includes a data receiving unit 41, a data processing unit 42, a main control unit 43, and an intensity adjustment unit 44. Among them, the data receiving unit 41 is connected to the eye tracker 6 to receive the user's eye movement data. The data processing unit 42 is connected to the data receiving unit 41 and is used to process the eye movement data. One end of the main control unit 43 is connected to the data processing unit 42, and the other end is connected to the stimulator 5 to receive the processing result of the data processing unit 42 and control the stimulation frequency of the stimulator 5 based on this processing result. In addition, the intensity adjustment unit 44 is connected to the main control unit 43, and the stimulation intensity can be freely set by using the intensity adjustment unit 44. After the stimulation intensity is set, the main control unit 43 controls the stimulator 5 to apply corresponding electrical stimulation according to the set stimulation intensity. It can be understood that the stimulation intensity depends on the user's own situation. When wearing this multifunctional glasses, the user can start adjusting from 0, increase it slowly in steps of 1 until feeling a tingling sensation, then reduce the amplitude by 1, and then adapt for 2 minutes to determine whether the amplitude is appropriate.

[0032] As Figure 1 shown, in this embodiment, a shaping member 7 is provided in the area of the temple 2 close to the ear, and the stimulator 5 is installed at one end of the shaping member 7 away from the temple. Specifically, the shaping member 7 is made of a shaping material, has a certain hardness, can be freely bent, and maintains the bent shape, so that the position of the stimulator 5 in the ear can be adjusted through the shaping member 7 to adapt to the ear contours of different users and improve the applicability of the multifunctional glasses.

[0033] Moreover, in this embodiment, preferably, a receiving groove 21 is formed at the bottom of the temple 2, and the shaping member 7 is flipably installed in the receiving groove 21 of the temple 2 to switch between a storage state (as Figure 3 shown) and an unfolded state (as Figure 1 shown). Among them, in the storage state, the shaping member 7 is parallel to the temple 2. At this time, the shaping member 7 and the stimulator 5 are jointly hidden in the receiving groove 21 of the temple 2, thus not affecting the normal use of the glasses and not affecting the aesthetics of the glasses. In the unfolded state, the shaping member 7 is perpendicular to the temple 2. At this time, by adjusting the shape of the shaping member 7, the stimulator 5 is stably in contact with the concha area of the user's ear.

[0034] In addition, as Figure 3As shown, in the above embodiment, a first conductive terminal 71 is provided at one end of the shaping member 7 close to the temple, and a second conductive terminal 22 is provided on the temple 2. In the storage state, the first conductive terminal 71 is disconnected from the second conductive terminal 22. At this time, the stimulator 5 is in a non-working state, and the multifunctional glasses are no different from ordinary glasses. In the unfolded state, the first conductive terminal 71 is electrically connected to the second conductive terminal 22. At this time, the stimulator 5 is in a working state, and the control chip 4 is used to control the stimulator 5 to apply an electrical stimulation of a specific intensity and continuously for a preset duration according to a preset frequency.

[0035] As Figure 1 shown, in this embodiment, the eye tracker 6 is disposed inside the lens 3 and fits on the edge of the lens 3 close to the nose pad to avoid the main visual field area of the lens 3. Thus, both the smooth acquisition of eye movement data is ensured, and a greater impact on the visual field is avoided. Preferably, in addition to being connected to the control chip 4, the eye tracker 6 can also be connected to the cloud by wireless connection to store the eye movement data of each user detection in the cloud. After a period of time, the eye movement data of the user within a period of time can be exported from the cloud, so that the stage vision change situation of the user can be analyzed, providing data support for subsequent myopia control.

[0036] In the above embodiment, preferably, the outer side of the lens 3 is coated with a film, and the film includes at least any one or more of an anti-reflection film, an anti-static film, or a durable top film. Thus, the use effect of the multifunctional glasses can be improved.

[0037] In the above embodiment, preferably, the frame 1 has a first hollow inner cavity inside, and the temple 2 has a second hollow inner cavity inside. The first hollow inner cavity is communicated with the second hollow inner cavity for accommodating wires, so as to connect the stimulator 5 and the eye tracker 6 to the control chip 4 by using the wires. It can be understood that since the wires are hidden inside the first hollow inner cavity and the second hollow inner cavity, the aesthetics and safety of use of the glasses are ensured.

[0038] As Figure 3 shown, in the above embodiment, preferably, a rechargeable power source 8 is further provided inside the temple 2, and the rechargeable power source 8 is electrically connected to the control chip 4. It can be understood that by using the rechargeable power source 8 to provide electrical energy, the multifunctional glasses can be used for a short time without being connected to an external power source, so as to improve the convenience of use of the multifunctional glasses. However, since the internal power of the rechargeable power source 8 is limited, if long-term use is required (for example, long-term work or reading), it is necessary to connect to an external power source using the power connection port 41 on the control chip 4.

[0039] In summary, the multifunctional glasses for controlling myopia progression provided by the embodiments of the present invention have the following beneficial effects:

[0040] (1) Innovatively apply transcutaneous auricular vagus nerve stimulation (taVNS) to the field of myopia control, opening up a new way to regulate the eye structure through the autonomic nervous system. This multifunctional glasses provides a safe and convenient means of myopia control by non-invasively electrically stimulating the concha area, avoiding the possible side effects of drug treatment and overcoming the limitations of optical correction.

[0041] (2) Use an eye tracker to monitor the changes in eye structure in real time, ensuring the optimization and individualized adjustment of stimulation parameters, thereby improving the treatment effect.
