Description

Technical Field

[0001] This invention relates to the field of medical optical instruments, and in particular to special glasses for farsightedness reserve in primary and secondary school students. Background Technology

[0002] The development of special glasses for farsightedness reserve in primary and secondary school students stems from the increasing prevalence of vision decline among teenagers in recent years. Due to factors such as academic pressure and increased use of electronic products, many students have developed farsightedness or other vision problems. To protect their eyesight, these special glasses were developed to provide a clear visual experience through optimized optical design, while slowing down vision deterioration and helping students to better learn and live.

[0003] However, in actual use, the following shortcomings still exist. For example, existing glasses specifically designed for farsighted reserve in primary and secondary school students cannot achieve blue light protection, clear vision, or wear resistance. The length and angle of the temples are not highly adjustable, and the lack of blue light protection allows harmful blue light to directly penetrate the lenses. Long-term exposure will aggravate damage to retinal photoreceptor cells, leading to eye fatigue, dryness, accelerated depletion of farsighted reserve, and an increased risk of myopia. The absence of an anti-reflective coating easily causes light reflection interference, resulting in blurred vision, forcing the eyes to over-accommodate, and further increasing the burden on the ciliary muscle. The lack of an anti-scratch coating makes the lenses prone to scratches, which not only affects light transmission but also causes abnormal eye posture due to obstructed vision. The inability to adjust the length and angle of the temples can lead to the frames slipping off and the bridge of the nose being too tight. Younger students may frequently adjust the frames due to discomfort, which distracts their attention and disrupts their eye distance. Older students may tilt their heads and squint due to incorrect frame size, inducing strabismus or aggravating refractive errors, ultimately weakening the protective effect of the glasses on farsighted reserve and violating the original design intention of specialized glasses.

[0004] Therefore, this invention proposes special glasses for farsightedness reserve in primary and secondary school students to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and propose special glasses for farsightedness reserve in primary and secondary school students.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a special pair of glasses for farsightedness reserve in primary and secondary school students, comprising a frame, and further comprising: An eyeglass lens assembly, which is assembled within a frame, includes a lens substrate made of PC optical substrate. The lens substrate is coated with an anti-blue light film, an anti-reflective film, and an anti-scratch film sequentially from the inside out. The anti-blue light film has a blocking rate of no less than 60% for harmful blue light in the 400-450nm wavelength band, the anti-reflective film increases the light transmittance of the lens to over 98.5%, and the anti-scratch film has a hardness of no less than 4H. An adjustment assembly includes a first temple rotatably connected to a frame. The first temple has a receiving cavity along its length at the end furthest from the frame, and a through-hole limiting groove is formed in the receiving cavity. A connecting block is slidably fitted within the receiving cavity of the first temple. A second temple is fixedly connected to the end of the connecting block furthest from the frame. A fixing seat is integrally formed on the side of the connecting block near the limiting groove. An elastic locking block is connected to the fixing seat and fitted with the limiting groove. A moving block is slidably embedded within the elastic locking block. A first hand-tight screw is threaded through the moving block, and the first hand-tight screw engages with a threaded groove corresponding to the position of the connecting block. A third temple is rotatably connected to the end of the second temple furthest from the connecting block via a hinge, and a second hand-tight screw for locking the rotation angle is threaded through the hinge.

[0007] Furthermore, a limiting block is integrally formed on the side of the movable block facing the elastic block, and a first limiting groove is opened on the inner wall of the elastic block corresponding to the limiting block. The limiting block and the first limiting groove form a sliding guide fit, and the nut end surface of the first hand-tightening screw is provided with anti-slip texture.

[0008] The beneficial effects of adopting the above-mentioned further solution are as follows: the limiting block on the moving block is embedded in the first limiting groove of the elastic block to form a sliding guide structure, ensuring that the moving block moves only along the axial direction without deviating. The anti-slip texture of the first hand-tightening screw and nut increases the friction force, making it easy to manually tighten. The moving block is pushed to squeeze the elastic block outward and expand. Tightening the first hand-tightening screw makes it more tightly engaged with the limiting groove, which not only fixes the length of the temple, but also ensures the stability of the adjustment process through the guide structure and prevents the block from loosening and falling off.

[0009] Furthermore, it also includes a monitoring and interaction component integrated on the frame and adjustment components. The monitoring and interaction component includes a miniature distance sensor and a miniature ambient light sensor mounted on the nose pad of the frame. The miniature distance sensor detects the reading and writing distance, and the miniature ambient light sensor can collect the ambient light intensity in real time.

[0010] The beneficial effects of adopting the above-mentioned further solutions are as follows: the miniature distance sensor at the nose pad of the eyeglass frame detects the distance between the eyes and the reading / writing object in real time through infrared ranging, accurately capturing close-range eye use behavior; the miniature ambient light sensor uses photosensitive elements to collect ambient light intensity, identifying excessively strong, weak, or stroboscopic light. Both types of sensors convert physical signals into electrical signals, providing real-time and accurate data support for subsequent eye use behavior intervention, forming the front-end sensing link of farsightedness reserve protection.

[0011] Furthermore, a housing is connected to the outer side of the first temple, and a flexible circuit board, a signal processing chip, and a power module are encapsulated inside the housing. The signal processing chip is electrically connected to a miniature distance sensor and a miniature ambient light sensor, respectively.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the outer shell of the first temple is sealed and encapsulated with a flexible circuit board, a signal processing chip and a power module. The flexible circuit board builds the circuit path, the signal processing chip receives the sensor electrical signal and analyzes the eye data through the built-in algorithm, the power module provides continuous power to the entire system, and the shell can protect against dust and collisions, ensuring that the components operate stably in students' daily use and realizing the integration of data processing and energy supply.

[0013] Furthermore, a miniature vibration motor is embedded inside the second temple, which is electrically connected to the signal processing chip, and magnetic charging contacts that are electrically connected to the power module are provided on the outside of the housing.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: when the signal processing chip detects abnormal eye use, it will send an electrical signal to the micro vibration motor. The motor will then send a gentle reminder to the wearer through vibration. The magnetic charging contacts on the outside of the shell are electrically connected to the power module, enabling convenient charging through magnetic attraction without the need for plugging and unplugging. This ensures charging efficiency and avoids interface wear, making it suitable for high-frequency use scenarios for students.

[0015] Furthermore, it also includes a protective assembly that can be detachably mounted on the front end of the frame. The protective assembly includes connecting seats symmetrically connected to the left and right ends of the frame. A guide hole is opened in the connecting seat along the horizontal direction. A guide rod slides through the guide hole. One end of the guide rod is connected to a limit ball. A telescopic spring is sleeved on the guide rod. The two ends of the telescopic spring abut against the inner wall of the connecting seat and the stepped surface of the guide rod, respectively.

[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: the guide hole of the connecting seat provides a horizontal sliding trajectory for the guide rod, and the two ends of the telescopic spring on the guide rod abut against the inner wall of the connecting seat and the step surface of the guide rod respectively, always maintaining elastic preload. When installing the transparent protective cover, the guide rod drives the limit ball to move with the mounting block, and the telescopic spring adapts to the position change through deformation, ensuring that the limit ball is accurately aligned with the second limit groove, providing guidance and elastic support for the stable assembly of the transparent protective cover.

[0017] Furthermore, a transparent protective cover is provided in front of the lens assembly, and a mounting block is connected to the transparent protective cover. A second magnetic block is embedded in the side of the mounting block facing the connector, and a first magnetic block is embedded in the connector corresponding to the position of the second magnetic block. The first magnetic block and the second magnetic block are attracted to each other by opposite poles.

[0018] The beneficial effects of adopting the above-mentioned further solution are: the mounting block of the transparent protective cover achieves initial positioning by the attraction between the second magnetic block and the first magnetic block of the connecting seat through opposite magnetic properties. At the same time, the telescopic spring pushes the guide rod, causing the limiting ball to be inserted into the second limiting groove of the mounting block, forming a dual fixing structure of mechanical snap-fit, magnetic attraction and snap-fit. This ensures that the transparent protective cover is assembled stably and is easy to manually disassemble and replace, adapting to the needs of lens protection and daily maintenance.

[0019] Furthermore, the mounting block has a second limiting groove on the side facing the limiting ball that is adapted to the limiting ball, and the limiting ball is inserted into the second limiting groove under the elastic force of the telescopic spring.

[0020] The beneficial effects of adopting the above-mentioned further solution are: the elastic force of the telescopic spring continuously pushes the guide rod, so that the limiting ball is tightly locked into the second limiting groove of the mounting block. The mechanical locking strengthens the fixing effect of the transparent protective cover, the magnetic structure achieves initial positioning, and the elastic locking further locks it, preventing the transparent protective cover from falling off due to shaking or collision. When disassembling, only external force needs to be applied to overcome the elastic force and magnetic force of the telescopic spring, and it can be easily separated, taking into account both the reliability of fixing and the convenience of operation.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, the glasses achieve protection and adaptation functions through the coordinated use of lens assembly and adjustment assembly. In the lens assembly, the PC substrate lens matrix serves as the core carrier. The anti-blue light film specifically blocks harmful blue light, reduces eye fatigue, and protects farsightedness reserves. The anti-reflective film improves light transmittance and reduces glare interference to ensure clear vision. The anti-scratch film resists wear and is suitable for student use. In the adjustment assembly, the first temple cavity allows the connecting block to slide. The elastic block on the fixed base engages with the limiting slot to complete the initial length positioning. The moving block is pushed to the end of the elastic block and the first hand-tightening screw is turned to enhance the engagement stability of the elastic block. The second and third temples rotate via hinges to adapt to the head shape. The second hand-tightening screw locks the angle, achieving blue light protection, clear vision, and wear resistance. The length and angle of the temples are adjustable, providing strong adaptability.

[0022] 2. In this invention, in the monitoring and interaction component, the miniature distance sensor at the nose pad accurately detects the reading and writing distance using infrared ranging, and the miniature ambient light sensor simultaneously collects the ambient light intensity. Both convert physical signals into electrical signals and transmit them to the signal processing chip inside the first temple housing. The flexible circuit board establishes the circuit path between components. The signal processing chip analyzes the data through a built-in algorithm. If it identifies situations such as prolonged close-range eye use or abnormal lighting, it immediately triggers the miniature vibration motor inside the second temple to emit a gentle vibration reminder. The power module supplies power to the entire system, and the magnetic charging contacts on the outside of the housing enable convenient charging, ensuring the continuous and stable operation of the component.

[0023] 3. In this invention, the protective component achieves stable assembly and convenient disassembly of the transparent protective cover through magnetic positioning and elastic snap-fit. The connecting seat on the lens frame serves as the core support, and its guide hole provides a horizontal sliding trajectory for the guide rod. The telescopic spring on the guide rod always maintains preload. During installation, the mounting block of the transparent protective cover approaches the connecting seat, and the first and second magnetic blocks attract each other to complete the initial positioning. At the same time, the mounting block squeezes the limiting ball, pushing the guide rod to compress the telescopic spring. When the mounting block is in place, the second limiting groove aligns with the limiting ball, and the telescopic spring resets to push the guide rod, causing the limiting ball to snap into the second limiting groove to form a mechanical lock. During disassembly, external force is applied to overcome the magnetic force and spring force, and the transparent protective cover can be separated, achieving efficient protection and maintenance of the lens assembly.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1-7 As shown, this embodiment provides a technical solution: special glasses for farsightedness reserve in primary and secondary school students, including a frame 1, and further including: The lens assembly 2 is assembled inside the frame 1. The lens assembly 2 includes a lens substrate 21, which is made of PC optical substrate. The lens substrate 21 is sequentially laminated with an anti-blue light film 22, an anti-reflective film 23, and an anti-scratch film 24 from the inside to the outside. The anti-blue light film 22 has a blocking rate of no less than 60% for harmful blue light in the 400-450nm wavelength band. The anti-reflective film 23 increases the light transmittance of the lens to more than 98.5%. The anti-scratch film 24 has a hardness of no less than 4H. Adjustment assembly 3 includes a first temple 31 rotatably connected to the frame 1. The end of the first temple 31 away from the frame 1 has a receiving cavity along its length, and a through-hole limiting groove 32 is formed in the receiving cavity. A connecting block 34 is slidably fitted inside the receiving cavity of the first temple 31. A second temple 33 is fixedly connected to the end of the connecting block 34 away from the frame 1. A fixing seat 35 is integrally formed on the side of the connecting block 34 near the limiting groove 32. An elastic locking block 36, which engages with the limiting groove 32, is connected to the fixing seat 35. A moving block 37 is slidably embedded in the elastic locking block 36. A first hand-tightening screw 310 is threaded through the moving block 37. The first hand-tightening screw 310 engages with a threaded groove 311 corresponding to the position of the connecting block 34. A third temple 313 is rotatably connected to the end of the second temple 33 away from the connecting block 34 via a hinge 312. A locking mechanism for the rotation angle is threaded through the hinge 312. The second hand-tightening screw 314 is used to tighten the first hand-tightening screw 310. The glasses achieve protection and adaptation functions through the lens assembly and adjustment assembly 3. In the lens assembly, the PC substrate lens matrix 21 is the core carrier. The anti-blue light film 22 specifically blocks harmful blue light, reduces eye fatigue and protects farsightedness reserve. The anti-reflective film 23 improves light transmittance and reduces reflection interference to ensure clear vision. The anti-scratch film 24 resists wear and is suitable for student use. In the adjustment assembly 3, the first temple 31 has a cavity for the connecting block 34 to slide. The elastic block 36 on the fixed seat 35 is engaged with the limiting slot 32 to complete the initial length positioning. The moving block 37 is pushed to the end of the elastic block 36 and the first hand-tightening screw 310 is turned to strengthen the engagement stability of the elastic block 36. The second temple 33 and the third temple 313 are rotated through the hinge 312 to adapt to the head shape. The second hand-tightening screw 314 locks the angle to achieve blue light protection, clear vision and wear resistance. The length and angle of the temples are adjustable and highly adaptable.

[0028] like Figure 4 As shown, a limiting block 38 is integrally formed on the side of the movable block 37 facing the elastic locking block 36. A first limiting groove 39 is opened on the inner wall of the elastic locking block 36 corresponding to the limiting block 38. The limiting block 38 and the first limiting groove 39 form a sliding guide fit. The nut end surface of the first hand-tightening screw 310 is provided with anti-slip texture. The limiting block 38 on the movable block 37 is embedded in the first limiting groove 39 of the elastic locking block 36 to form a sliding guide structure, ensuring that the movable block 37 moves only along the axial direction without deviating. The anti-slip texture of the nut of the first hand-tightening screw 310 increases the friction force, making it easy to manually tighten. The movable block 37 pushes the elastic locking block 36 to expand outward. Tightening the first hand-tightening screw 310 makes it more tightly engaged with the limiting groove 32, which not only fixes the length of the temple, but also ensures the stability of the adjustment process through the guide structure, preventing the locking block from loosening and falling off. like Figure 1 as well as Figure 5As shown, it also includes a monitoring and interaction component 4 integrated on the frame 1 and adjustment assembly 3. The monitoring and interaction component 4 includes a miniature distance sensor 41 and a miniature ambient light sensor 42 mounted on the nose pad of the frame 1. The miniature distance sensor 41 detects the reading and writing distance, and the miniature ambient light sensor 42 can collect the ambient light intensity in real time. The miniature distance sensor 41 at the nose pad of the frame 1 detects the distance between the eyes and the reading / writing object in real time through infrared ranging, accurately capturing near-distance eye use behavior. The miniature ambient light sensor 42 uses a photosensitive element to collect the ambient light intensity and identify excessively strong, weak, or flickering light. The two types of sensors convert physical signals into electrical signals, providing real-time and accurate data support for subsequent eye use behavior intervention, forming the front-end sensing link of farsightedness reserve protection. A housing 43 is connected to the outside of the first temple 31. The housing 43 encapsulates a flexible circuit board 44, a signal processing chip 45, and a power module 46. The signal processing chip 45 is electrically connected to the miniature distance sensor 41 and the miniature ambient light sensor 42, respectively. The outer shell 43 of the temple 31 encapsulates a flexible circuit board 44, a signal processing chip 45, and a power module 46. The flexible circuit board 44 establishes the circuit path. The signal processing chip 45 receives electrical signals from the sensor and analyzes eye data through a built-in algorithm. The power module 46 continuously supplies power to the entire system. The shell 43 provides dust and impact protection, ensuring stable operation of the components during students' daily use and achieving integration of data processing and energy supply. A miniature vibration motor 47 is embedded inside the second temple 33. The miniature vibration motor 47 is electrically connected to the signal processing chip 45. The outer shell 43 has a magnetic charging contact 48 that is electrically connected to the power module 46. When the signal processing chip 45 detects an abnormal eye condition, it sends an electrical signal to the miniature vibration motor 47. The motor then vibrates to gently remind the wearer. The magnetic charging contact 48 on the outer shell 43 is electrically connected to the power module 46, enabling convenient charging via magnetic attraction without the need for plugging or unplugging. This ensures charging efficiency and avoids interface wear, making it suitable for students' high-frequency use scenarios. like Figure 1 as well as Figures 6-7As shown, it also includes a protective component 5 detachably mounted on the front end of the frame 1. The protective component 5 includes connecting seats 51 symmetrically connected to the left and right ends of the frame 1. A guide hole is opened in the connecting seat 51 along the horizontal direction. A guide rod 52 slides through the guide hole. One end of the guide rod 52 is connected to a limit ball 53. A telescopic spring 54 is sleeved on the guide rod 52. The two ends of the telescopic spring 54 abut against the inner wall of the connecting seat 51 and the stepped surface of the guide rod 52, respectively. The guide hole of the connecting seat 51 provides a horizontal sliding trajectory for the guide rod 52. The two ends of the telescopic spring 54 on the guide rod 52 abut against the inner wall of the connecting seat 51 and the stepped surface of the guide rod 52, respectively. The stepped surface of rod 52 maintains an elastic preload at all times. When installing the transparent protective cover 56, the guide rod 52 drives the limiting ball 53 to move with the mounting block 57. The telescopic spring 54 adapts to the position change through deformation, ensuring that the limiting ball 53 is accurately aligned with the second limiting groove 59, providing guidance and elastic support for the stable assembly of the transparent protective cover 56. The transparent protective cover 56 is made of impact-resistant PC material with a light transmittance of not less than 95%. The front of the spectacle lens assembly 2 is covered by the transparent protective cover 56. The mounting block 57 is connected to the transparent protective cover 56. A second magnetic block 58 is embedded on the side of the mounting block 57 facing the connecting seat 51. A first magnetic block 55 is embedded in the connector 51 at the position corresponding to the second magnetic block 58. The first magnetic block 55 and the second magnetic block 58 are attracted by opposite poles. The mounting block 57 of the transparent protective cover 56 is initially positioned by the attraction between the second magnetic block 58 and the first magnetic block 55 of the connector 51. At the same time, the telescopic spring 54 pushes the guide rod 52, causing the limiting ball 53 to engage with the second limiting groove 59 of the mounting block 57, forming a mechanical engagement. This dual fixing structure of magnetic attraction and engagement ensures the stable assembly of the transparent protective cover 56 and facilitates manual disassembly and replacement, adapting to the needs of lens protection and daily maintenance. The mounting block 57 faces the limiting ball 53. A second limiting groove 59 adapted to the limiting ball 53 is provided on the side. Under the elastic force of the telescopic spring 54, the limiting ball 53 is inserted into the second limiting groove 59. The elastic force of the telescopic spring 54 continuously pushes the guide rod 52, so that the limiting ball 53 is tightly inserted into the second limiting groove 59 of the mounting block 57. The mechanical snap-fit ​​strengthens the fixing effect of the transparent protective cover 56. The magnetic structure achieves initial positioning, and the elastic snap-fit ​​further locks it, preventing the transparent protective cover 56 from falling off due to shaking or collision. When disassembling, only external force needs to be applied to overcome the elastic force and magnetic force of the telescopic spring 54 to easily separate it, taking into account both the reliability of the fixation and the convenience of operation.

[0029] Working principle: like Figures 1-7As shown, the lens assembly is the core of visual protection. The lens substrate 21, made of PC optical material, serves as the basic carrier. Three functional films are composited from the inside out: the blue light blocking film 22 specifically blocks more than 60% of harmful blue light in the 400-450nm wavelength band, reducing eye fatigue and protecting farsightedness reserve; the anti-reflective film 23 increases light transmittance to more than 98.5% and reduces reflective interference; and the scratch-resistant film 24 resists wear with a hardness of not less than 4H, making it suitable for student use. The adjustment component 3 achieves a proper fit, and the connecting block 34 inside the cavity of the first temple 31 drives the second temple. The length of the 33-sliding adjustment is achieved by the elastic block 36 on the fixed base 35 engaging with the limiting slot 32 for initial positioning. The moving block 37 moves axially through the guide cooperation between the limiting block 38 and the first limiting slot 39. Tightening the first hand-tightening screw 310 with anti-slip texture can compress the elastic block 36 to expand, enhancing the locking stability. The second temple 33 and the third temple 313 are rotated to adapt to the head shape via the hinge 312. The second hand-tightening screw 314 locks the angle to ensure fit. The monitoring and interaction component 4 enables eye health management. The miniature distance sensor 41 at the nose pad... Infrared ranging monitors the reading and writing distance, and a miniature ambient light sensor 42 collects light intensity. Both convert physical signals into electrical signals. The signal processing chip 45 inside the housing 43 of the first temple 31 receives the signals and analyzes them through an algorithm. If close-range eye use or abnormal lighting is detected, a miniature vibration motor 47 inside the second temple 33 is triggered to gently vibrate as a reminder. The power module 46 provides power, and the magnetic charging contacts 48 enable convenient charging to ensure continuous operation. The protective component 5 enhances lens protection, and the transparent protective cover 56 is attached to the frame via the second magnet 58 of the mounting block 57. The first magnetic block 55 of the connector 51 is initially positioned by the attraction of opposite poles. The telescopic spring 54 inside the connector 51 pushes the guide rod 52, so that the limiting ball 53 is engaged with the second limiting groove 59 of the mounting block 57 to form a mechanical engagement. The double fixation prevents it from falling off, and it can be disassembled and maintained by external force. The transparent protective cover 56 is made of impact-resistant PC material with a light transmittance of not less than 95%. It achieves visual protection through functional lenses, and is also adapted to wearing with adjustable temples. It further protects eye health with sensor monitoring and vibration reminders. The detachable protective cover enhances protection and fully meets the needs of students.
