Abstract
Description
Technical Field
[0001] This utility model relates to the field of smart glasses technology, and in particular to myopia prevention and control lenses and smart glasses. Background Technology
[0002] With the increasing amount of time spent using eyes at close range in modern society, especially among teenagers, myopia is becoming increasingly serious. Myopia not only affects visual clarity but can also lead to excessive elongation of the axial length of the eye, ultimately resulting in a series of eye diseases such as retinal degeneration. Therefore, how to effectively prevent and control the development of myopia has become an important issue in the current eyewear industry and optical research field. To this end, glasses incorporating smart technology and specially designed myopia-preventing lenses are gradually becoming effective means of myopia control. Myopia-preventing lenses aim to slow down excessive elongation of the axial length of the eye by optimizing optical design, reducing low-order aberrations, and improving visual comfort. Smart glasses, on the other hand, integrate sensors to monitor eye behavior during wear, helping users develop healthy eye habits and achieving better myopia control.
[0003] In existing technologies, many myopia control lenses employ specific optical structures, such as graduated focus designs and aspherical designs, to reduce aberrations and improve retinal image quality. Meanwhile, smart glasses technology is gradually being integrated into this field, incorporating features such as wear time monitoring, eye distance measurement, and voice prompts. Some products integrate pressure sensors and distance sensors into the frame, achieving an intelligent wearing experience and using embedded systems to help users adjust their eye habits, thereby reducing the negative impact of prolonged eye strain. However, existing myopia control lenses and smart glasses still face some technological bottlenecks, failing to fully optimize visual quality and user experience during wear.
[0004] Current myopia control lenses are still not effectively designed to reduce low-order aberrations, resulting in insufficient retinal image quality. This is especially true for children and adolescents, where excessive axial elongation is often closely related to the accumulation of low-order aberrations. The presence of low-order aberrations not only affects visual acuity but may also lead to instability in axial development, thereby exacerbating the occurrence and progression of myopia. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides myopia prevention and control lenses and smart glasses, aiming to improve the problem that the design of existing myopia prevention and control lenses is still difficult to effectively reduce low-order aberrations, resulting in insufficient retinal imaging quality.

[0007] The protective component includes a dot-diffusion frosted layer and a hollow portion. The dot-diffusion frosted layer is disposed on one side of the outer wall of the lens, and the hollow portion is disposed in the middle of the dot-diffusion frosted layer. A double-sided anti-reflective film and a high-transmittance and high-cleanliness UV film are sequentially disposed on both sides of the outer wall of the lens. The lens is made of resin material.
[0008] Furthermore, an earphone is mounted on the outer wall of one of the eyeglass frames, a power supply is provided inside the other eyeglass frame, and a monitoring component is provided on the outer wall of the nose bridge frame.
[0009] Furthermore, the monitoring component includes a miniature pressure sensor and a distance sensor. The miniature pressure sensor is installed on the upper side of the outer wall of the nose bridge, and the distance sensor is fixedly connected to one side of the outer wall of the eyeglass frame. A buzzer is installed inside the eyeglass frame.
[0010] Furthermore, the lens is designed to be thinner in the center and thicker at the edges to reduce peripheral low-order aberrations.
[0011] Furthermore, the dots inside the dot diffusion frosted layer are arranged in a ring array, and the dot diffusion frosted layer adopts a gradient defocusing design and is attached to the outer wall of the lens.
[0012] Furthermore, the ranging sensor is positioned above the miniature pressure sensor to monitor the position of the lens.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, the dot-diffusion frosted layer and gradient defocus design optimize retinal imaging, reduce low-order aberrations, and lower the risk of excessive axial elongation, effectively preventing the development of myopia. At the same time, the outer wall of the lens is covered with a double-sided anti-reflective film and a high-transmittance and high-cleanliness UV film, which improves light transmittance and blocks ultraviolet rays, protecting the eyes from damage.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figures 1-4The present invention provides an embodiment of a myopia prevention and control lens, including a frame 1. The frame 1 serves as the basic frame of the smart glasses, providing the structural foundation to support all other components, bearing and connecting all key functional parts. Both ends of the frame 1 are rotatably connected to a frame 2. The frame 2 is connected to the frame 1 and surrounds the lens 4. Its function is to stabilize the position of the glasses so that they can be securely worn on the user's face. An anti-slip sleeve 3 is fixedly connected to the outer wall of the frame 2. The lens 4 is fixedly connected to one side of the outer wall of the frame 1. A nose bridge 5 is fixedly connected to the middle of the outer wall of the frame 1. A protective component is provided on the outer wall of the lens 4.
[0025] The protective components include a dot-diffusing frosted layer 401 and a hollow portion 402. The dot-diffusing frosted layer 401 is disposed on one side of the outer wall of the lens 4. Through the dot distribution of the ring array, the gradient defocus design effectively reduces low-order aberrations in retinal imaging, avoids excessive elongation of the axial length, and prevents the development of myopia. The hollow portion 402 is disposed in the middle of the dot-diffusing frosted layer 401. A double-sided anti-reflective film 403 and a high-transmittance and high-cleanliness UV film 405 are disposed sequentially on both sides of the outer wall of the lens 4. The double-sided anti-reflective film 403 reduces light reflection and increases light transmittance, allowing the eyes to obtain a clearer visual effect. The high-transmittance and high-cleanliness UV film 405 effectively blocks ultraviolet rays and protects the eyes from ultraviolet damage. The lens 4 is made of resin material 404.
[0026] Specifically, a dot-diffusion frosted layer 401 is used, in which the dots are distributed in a ring array and combined with a gradient defocus design. By scientifically optimizing retinal imaging, peripheral low-order aberrations are reduced, thereby avoiding excessive elongation of the axial length and reducing the risk of myopia development. At the same time, the lens 4 adopts a multi-layer structure design, with the outer wall successively covered by a double-sided anti-reflective film 403 and a high-transmittance and high-cleanliness UV film 405. The double-sided anti-reflective film 403 can effectively reduce light reflection, improve light transmittance, and enhance visual clarity, while the high-transmittance and high-cleanliness UV film 405 can effectively block harmful ultraviolet rays from damaging the eyes, reduce visual fatigue, and improve the comfort of prolonged eye use. In addition, the lens 4 is made of resin material layer 404 and adopts a structure design that is thin in the middle and thick at the edges. This not only optimizes the distribution of optical focus and helps to relieve visual fatigue, but also reduces the interference of peripheral low-order aberrations on vision, thereby further optimizing visual quality and achieving effective myopia control.
[0027] Reference Figure 1 and Figure 5One of the frames 2 has an earphone 8 installed on its outer wall, and the other frame 2 has a power supply unit 10 inside. The nose bridge 5 has a monitoring component on its outer wall, which includes a miniature pressure sensor 6 and a distance sensor 7. The monitoring component is installed on the outer wall of the nose bridge 5 to monitor the wearing stability. By sensing the wearing pressure, it can determine whether the glasses are secure and whether adjustments are needed. The miniature pressure sensor 6 is installed on the upper side of the outer wall of the nose bridge 5. A distance sensor 7 is fixedly connected to one side of the outer wall of the frame 1 and is installed on the outer wall of the frame 1. It is responsible for measuring the distance between the eyes and the book or screen. A buzzer 9 is installed inside the frame 1. The buzzer 9 serves as an alert device and can emit an audible alarm to remind the wearer to adjust their posture and viewing distance, etc., to prevent myopia from worsening due to prolonged close-range use of the eyes. The lens 4 has an overall design that is thin in the middle and thick at the edges to reduce peripheral low-order aberrations. The dots inside the dot diffusion frosted layer 401 are arranged in a ring array. The dot diffusion frosted layer 401 adopts a gradient defocus design and is attached to the outer wall of the lens 4. The distance sensor 7 is located above the miniature pressure sensor 6 and is used to monitor the position of the lens 4.
[0028] Specifically, a miniature pressure sensor 6 is installed on the outer wall of the nose bridge 5. This sensor can accurately detect the wearing status of the glasses, including whether they are securely worn and whether they have been worn for a long time. The system records the user's wearing time to ensure reasonable use. In addition, a distance sensor 7 is fixedly connected to the outer wall of the frame 1. This sensor can monitor the distance between the wearer's eyes and the book or screen in real time. When it detects that the wearer's reading distance is less than the set safe range, it will trigger the buzzer 9 to sound an alarm, prompting the user to adjust the viewing distance and prevent myopia from worsening due to prolonged close-range use of the eyes. A power supply unit 10 is built into one side of the frame 2 to ensure a stable power supply for the entire intelligent monitoring system, enabling it to operate continuously and efficiently. An earphone 8 is installed on the other side, which can provide voice reminders, convey eye care suggestions to the user in real time, and guide them to develop scientific eye care habits.
[0029] Working principle: When myopia prevention and control lenses and smart glasses are needed, lens 4 adopts a dot diffusion frosted layer 401, in which the internal dots are arranged in a ring array. Combined with a gradient defocus design, it can optimize retinal imaging, reduce peripheral low-order aberrations, and reduce the risk of excessive axial elongation. In addition, the outer wall of lens 4 is covered with a double-sided anti-reflective film 403 and a high-transmittance and high-cleanliness UV film 405 in sequence to reduce reflection, increase light transmittance, and effectively filter harmful ultraviolet rays. The main body of lens 4 is made of resin material layer 404. The overall design is a structure that is thin in the middle and thick at the edges, which helps to control peripheral visual aberrations and improve visual quality.
[0030] In addition, a miniature pressure sensor 6 is installed on the outer wall of the nose bridge 5. The specific model of the miniature pressure sensor 6 is CYG500. It is used to detect the stability of the glasses and record the user's wearing time. A distance measuring sensor 7 is fixedly connected to the outer wall of the frame 1. The specific model of the distance measuring sensor 7 is E3ZG-LS. It can accurately measure the distance between the user's eyes and the book or screen. If the reading distance is detected to be less than the set safe range, the buzzer 9 will be triggered to remind the user and prevent myopia from worsening due to prolonged close-range use of the eyes. In addition, a power supply unit 10 is integrated on one side of the frame 2 to ensure the stable operation of the monitoring system, while an earphone 8 is installed on the other side to provide voice reminders or eye protection guidance to help users develop healthy eye habits.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
