Description

Technical Field

[0001] The present invention relates to the technical field of glasses, and in particular to glasses for preventing myopia. Background Art

[0002] With the increase in the number of myopic people, the increase in myopia is almost an irreversible trend. This is because after becoming myopic, one must wear glasses to adjust the lens so that the lens can adapt to seeing things at a certain degree. Over time, the dependence on glasses becomes greater, and long-term wearing of glasses will cause the myopia degree to show an upward trend.

[0003] In the prior art, the Chinese patent document for preventing myopia with publication number CN210323648U proposes that a control mechanism is installed on the first temple, a power mechanism is installed on the second temple, and the control mechanism and the power mechanism are connected through a conductive mechanism; the weight of the power mechanism and the control mechanism are matched so that the weight of the first temple and the second temple are relatively balanced. However, consistent with the traditional method, traditional glasses for preventing myopia usually adopt a fixed focal length design, which cannot be dynamically adjusted according to different viewing distance requirements, resulting in the wearer being unable to achieve the best visual effect in different environments. For example, when reading at a close distance for a long time or looking far away for a long time, fixed-focal length glasses cannot provide adaptive support, which can easily cause eye fatigue. Therefore, the present application discloses a pair of glasses for preventing myopia to meet the dynamic adjustment of viewing distance of glasses for preventing myopia. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a pair of myopia prevention glasses to solve the problem that traditional myopia prevention glasses are usually unable to be dynamically adjusted according to different viewing distance requirements.

[0005] Based on the above purpose, the present invention provides a pair of glasses for preventing myopia, comprising a frame, wherein a first temple and a second temple are rotatably mounted on both sides of the frame, two frames are respectively arranged on the frame, fixed convex lenses are arranged in both frames, and a nose pad is arranged at the bottom of the middle part of the frame; A dynamic adjustment component, the dynamic adjustment component is arranged on one side of the fixed convex lens, the dynamic adjustment component is used to adjust the equivalent focal length of the fixed convex lens, and is used to simulate a dynamic defocusing state; A reminder component is arranged inside the first temple and the second temple, and is used to remind the user to keep the eye on the temple when performing myopia prevention adjustment.

[0006] Preferably, the dynamic adjustment component comprises a plane lens arranged on one end surface of the fixed convex lens, the plane lens is in close contact with the fixed convex lens, and the plane lens is slidably mounted on the fixed convex lens.

[0013] Beneficial effects of the present invention: 1. This type of glasses for preventing myopia is equipped with a dynamic adjustment component. By operating the adjustment wheel, the user can easily adjust the focal length of the lens group to adapt to different visual scenes at different distances and near, and effectively relieve visual fatigue. The transparent liquid (including glycerin) is used as an optical medium to improve the sliding stability between lenses and optimize the optical effect, making the focal length adjustment smoother and more precise, while increasing the adjustment range of the focal length. The high light transmittance and stability of the liquid ensure that the visual clarity is not affected during the adjustment process. The incomplete cylindrical structure and friction strip design of the adjustment wheel enhance the sensitivity and feel of the operation, simplify the user's use process, and make the focal length adjustment more convenient. On the whole, the dynamic adjustment component provides users with technical support for active adjustment, and can flexibly switch the focal length according to actual needs, which not only improves eye comfort, but also provides an effective solution for myopia prevention and control.

[0014] 2. This type of anti-myopia glasses is equipped with a reminder component, which monitors the wearing time through a camera and determines whether the user uses the glasses for a long time or has bad eye habits based on a preset algorithm. When the reminder conditions are met, the control panel emits a prompt sound or voice through the speaker to remind the user to rest or adjust his posture, thereby effectively avoiding eye fatigue and vision deterioration. This function enhances eye health management, helps users develop scientific eye habits, reduces the risk of worsening myopia, and improves eye comfort and long-term health.

[0018] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0019] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

"Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0020] like Figures 1 to 8 As shown, the myopia prevention glasses include a frame 1, a first temple 2 and a second temple 3 are rotatably installed on both sides of the frame 1, two frames are respectively arranged on the frame 1, fixed convex lenses 4 are arranged in the two frames, two movable convex lenses 5 are also slidably installed in the two frames, the two movable convex lenses 5 are of the same specifications as the two fixed convex lenses 4, and a nose pad 13 is arranged at the middle bottom end of the frame 1; a dynamic adjustment component, the dynamic adjustment component is arranged on one side of the fixed convex lens 4, the dynamic adjustment component is used to adjust the equivalent focal length of the fixed convex lens 4, and is used to simulate a dynamic defocus state; a reminder component, the reminder component is arranged inside the first temple 2 and the second temple 3, and the reminder component is used to remind the user to keep the eye when performing myopia prevention adjustment; When the user wears this pair of glasses for preventing myopia, the movable convex lens 5 and the fixed convex lens 4 are combined to form an initial optical focal length. The user first selects an appropriate adjustment mode according to his or her own needs. If special adjustments for preventing myopia are required, the user activates the dynamic adjustment component. The dynamic adjustment component simulates different defocus states by changing the equivalent focal length of the fixed convex lens 4. During this process, the wearer uses the convex lens to look at distant objects in a targeted manner. The optical properties of the convex lens prompt the eye lens to relax and adjust in the opposite direction, that is, adjust in the original normal direction. In this state, the lens can relieve tension, reduce continuous fatigue caused by close-range eye use, and promote vision recovery. In this state, the wearer Continue to observe the distance through the convex lens to keep the lens in a state of relaxation and adjustment, avoid the weakening of the elasticity of the lens due to the fixed focal length, especially for low-degree myopia, which can reduce the degree or even keep away from myopia through long-term persistence; for high-degree myopia, the degree can also be effectively controlled. During this period, the reminder component monitors the user's eye stay time in real time. If the user stays too long at a fixed viewing distance, the speaker 14 will issue a prompt to remind the user to change the direction of gaze or take a break. This process not only allows the optical relaxation function of the convex lens to continue to play a role, but also protects eye health through dynamic and timely adjustment, helps to develop scientific eye habits, and achieves comprehensive myopia prevention and vision management; For various groups of people (including young children who have not yet discovered myopia), it is targeted to wear a pair of convex glasses with a certain degree. Use the extracurricular time or rest time to look into the distance for 5-8 minutes to relax and decompress the eyes, allowing the lens to adjust in the opposite direction, that is, to adjust in the original normal direction. This is also a relaxing adjustment for the lens itself, which helps to restore vision. If this is persisted for a long time, it can reduce the degree of myopia or even keep away from myopia for people who originally have a low degree of myopia. It also has a certain auxiliary effect on people with high myopia and makes their degree effectively controllable.

[0021] like Figure 3 , Figure 4 , Figure 5 As shown, the dynamic adjustment component includes a plane lens 7 arranged on one end face of a fixed convex lens 4, the plane lens 7 is in close contact with the fixed convex lens 4, the plane lens 7 is slidably mounted on the fixed convex lens 4, an extension plate 8 is arranged above the plane lens 7, the extension plate 8 is arranged to penetrate to the top of the frame 1, a plurality of first teeth 9 are arranged on one side of the extension plate 8, and an adjustment wheel 10 is rotatably mounted on both sides of the frame 1, a plurality of second teeth 11 meshing with the first teeth 9 are arranged on the side of the adjustment wheel 10 close to the extension plate 8, the adjustment wheel 10 is arranged as an incomplete cylinder, and a friction strip 12 is arranged on the side of the adjustment wheel 10 away from the extension plate 8, a sealed space is arranged between the plane lens 7 and the fixed convex lens 4, the sealed space is arranged in a transparent frame shape, a transparent liquid is injected into the sealed space between the plane lens 7 and the fixed convex lens 4, and the transparent liquid is arranged as glycerin; After the user wears the glasses, he decides whether to start the dynamic adjustment function according to the visual distance requirement. By manually rotating the adjustment wheel 10, the second teeth 11 on the adjustment wheel 10 mesh with the first teeth 9 on the extension plate 8, and the rotational motion is converted into a linear sliding motion of the extension plate 8. The sliding of the extension plate 8 pushes the plane lens 7 to slide along the end surface of the fixed convex lens 4, and the relative position between the two is adjusted, thereby changing the synthetic focal length of the lens group. During the adjustment process, the transparent liquid (containing glycerin) in the sealed space between the plane lens 7 and the fixed convex lens 4 acts as an optical medium. The presence of the liquid not only improves the smoothness of the sliding between the lenses, but also improves the stability of the lens through the synergistic effect of its refractive index. The optical effect is optimized and the dynamic adjustment range of the focal length is expanded. The transparent liquid has stability and high light transmittance, which ensures the visual clarity during the adjustment process. The incomplete cylindrical structure of the adjustment wheel 10 and the friction strip 12 design enhance the sensitivity and feel of the user's rotation operation, making the adjustment more precise. After the adjustment is completed, the user confirms that the focal length has met the current viewing distance requirement through observation and feeling. The whole adjustment process is fast and without additional operation burden. In daily use, the dynamic adjustment function can flexibly switch the focal length in different eye scenarios (such as looking into the distance or working with myopia), effectively relieve visual fatigue and improve eye comfort, while providing technical support for active adjustment for myopia prevention and control.

[0022] like Figures 6 to 8 As shown, cameras 18 are provided on both sides of the frame 1, and the cameras 18 are used to monitor the usage time. The reminder component includes a speaker 14 fixedly installed inside the first temple 2 and the second temple 3. Sound holes 15 are provided on one side below the first temple 2 and the second temple 3, and the sound holes 15 correspond to the speakers 14. A control board 16 is also provided on one side of the first temple 2, and a battery is provided on one side of the control board 16. A charging line 17 is provided through the other side of the first temple 2. The control board 16 is electrically connected to the camera 18, and the control board 16 is electrically connected to the speaker 14. When the user wears the glasses, the cameras 18 located on both sides of the frame 1 start working, monitor the wearing time and transmit the data to the control board 16. The control board 16 records the wearing time according to the preset program and determines whether the reminder conditions are met through the built-in algorithm. For example, when wearing for a long time or detecting bad eye habits at a distance, the control board 16 sends a signal to the speaker 14. After receiving the signal, the speaker 14 plays a reminder sound effect or voice prompt through the corresponding sound outlet 15, such as "Please pay attention to rest" or "Please adjust your posture". The user adjusts the eye use method or takes off the glasses to rest according to the reminder, thereby avoiding eye fatigue and further deterioration of vision.
