[0028] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0030] The diffusion assembly includes a plurality of light diffusion points 6, which are in a special microlens structure, and the diameter of each point is accurately calculated to scatter light while maintaining sufficient light transmittance, ensuring the visual comfort of the user. The plurality of light diffusion points 6 are located inside the lens 4, which is made of a high light transmittance material to ensure the accuracy and stability of light propagation. The light diffusion points 6 are arranged in a ring array inside the lens 4, and the center of the lens 4 and the center of the plurality of light diffusion points 6 form a transparent correction area, which can provide clear central vision correction function and ensure the natural transition of the field of view.
[0031] Specifically, during use of the device, the lens 4 adopts an innovative optical design concept, which organically combines the central transparent correction area with the surrounding light diffusion points 6 to realize the dual functions of vision correction and myopia prevention and control. The central transparent correction area is accurately calculated and optimally designed, and adopts aspheric or freeform surface technology to ensure that the user can have clear visual correction effect at different distances, with refractive error controlled within ±0.02D, ensuring the comfort and visual clarity of daily eye use. Around the central transparent correction area, a plurality of accurately calculated light diffusion points 6 are uniformly distributed. These light diffusion points 6 adopt a special microlens array structure, and the diameter of each point is controlled between 0.5-1.2mm. The spacing is optimally designed to effectively scatter incident light. This design makes the fluorescent light produce moderate defocus after entering the eye, so as not to form a clear focal image on the retina, thereby reducing the gain intensity of the light, and the high gain signal received by the retina can be reduced by 30%-40%, effectively inhibiting the elongation signal of the eye to adapt to high-intensity light, thereby delaying the growth of the eye axis and slowing down the speed of myopia deepening. The lens 4 fully considers the ergonomics principle, adopts a high oxygen permeability material with a light transmittance of more than 98%, and has additional functions such as anti-blue light and anti-ultraviolet. The innovative dual-function area design not only effectively corrects vision, but also prevents and controls myopia from an optical principle, while considering the comfort and practicality of wearing, and provides all-round visual health protection for the user.
[0032] Reference Figure 1 and Figure 3The intelligent glasses include the point diffusion prevention and control lens described above: each leg 1 is internally slidably connected with an extension rod 5, the extension rod 5 is designed so that the length of the leg can be flexibly adjusted according to the user's needs, improving the wearing comfort, both sides of each leg 1 are internally slidably connected with a transmission plate 8, the transmission plate 8 is a core transmission component, ensuring uniform transmission of force, one side of each transmission plate 8 is fixedly connected with a push plate 7, the surface of the push plate 7 is designed with a non-slip texture, facilitating user operation, the other side of each transmission plate 8 is fixedly connected with a connecting plate 11, the connecting plate 11 is a connection hub, ensuring coordinated operation of each component, each connecting plate 11 is tightly fitted with the inner wall of the leg 1, this tight fitting design reduces the gap between components, improving structural stability, the inner wall of each connecting plate 11 is fixedly connected with a clamping ball 12, the clamping ball 12 is made of high-hardness stainless steel, ensuring reliability during long-term use, each clamping ball 12 is clamped with the inside of the extension rod 5, this clamping structure provides precise positioning function, one side of each push plate 7 is fixedly connected with a plurality of transmission bars 9, the transmission bars 9 are made of high-strength alloy material, ensuring smooth transmission, each transmission bar 9 is slidably connected inside the leg 1, the sliding connection reduces friction loss, a plurality of springs 10 are arranged inside each leg 1, one end of the spring 10 is fixedly connected to the outer wall of the transmission bar 9, the other end of the spring 10 is fixedly connected to the inside of the leg 1, this symmetrical design ensures balanced distribution of force.
[0033] Specifically, in the process of adjusting the length of the leg 1, the user first presses the push plate 7, through mechanical linkage, the transmission plate 8 is displaced, pushing the clamping ball 12 in the inner wall of the connecting plate 11 to separate from the clamping groove in the inside of the extension rod 5, in this process, the transmission bar 9 moves synchronously, exerting pressure on the spring 10 to make it compressively deform, at this time the extension rod 5 smoothly slides in the guide groove in the inner wall of the leg 1, when the extension rod 5 moves to the appropriate position, the user releases the pressing force on the push plate 7, at this time the compressed spring 10 pushes the connecting plate 11 back to its original position under the action of elastic restoring force, making the clamping ball 12 in the inner wall of the connecting plate 11 re-clamp with the pre-set positioning groove in the inside of the extension rod 5, the clamping ball 12 is made of high-hardness stainless steel, and the surface is treated with special hardening to ensure reliability during long-term use, the inside of the extension rod 5 is provided with multiple groups of equidistantly distributed positioning grooves, the groove spacing is 2.5 mm, which can provide multi-gear precise adjustment to meet the individual needs of different users.
[0034] Working principle: during the use of the device, the lens 4 adopts the design of combining the central transparent correction area and the surrounding light diffusion points 6 to realize the dual functions of vision correction and myopia prevention and control. The central transparent correction area provides clear vision correction effect for the user through accurate optical design, ensuring the comfort and clarity of daily eye use. The surrounding multiple light diffusion points 6 scatter light, so that the fluorescent light is out of focus and not clearly imaged on the retina, thereby reducing the gain intensity of the light, reducing the high gain signal received by the retina, effectively inhibiting the elongation signal generated by the eye to adapt to high-intensity light, thereby delaying the growth of the eye axis and slowing down the speed of myopia deepening. It is suitable for teenagers and people who use their eyes for a long time, and can correct vision and prevent and control myopia from the root, while considering the comfort and practicality of wearing.
[0035] During the adjustment of the length of the temple 1, press the push plate 7, and separate the clamping ball 12 on the inner wall of the connecting plate 11 from the extension rod 5 by pushing the connecting plate 11 through the transmission plate 8. In this process, the transmission bar 9 will push the spring 10 to generate compression, and then push the extension rod 5 to slide in the inner wall of the temple 1. When the extension rod 5 moves to the appropriate position, the pressing force of the push plate 7 is sent, and the rebounding force of the spring 10 is used to push the clamping ball 12 on the inner wall of the connecting plate 11 to be engaged with the inside of the extension rod 5, so as to fix the position of the extension rod 5 and enhance the applicability of the device.
