Description

Technical Field

[0001] The present invention relates to the technical field of glasses, and in particular to a pair of myopia reduction glasses with chip for correction and prevention. Background Art

[0002] In recent years, the widespread use of electronic products has led to a growing number of people with myopia. According to relevant reports, myopia in adolescents is most commonly caused by long-term close viewing. However, adolescents have a strong ability to accommodate objects, and can still see clearly when a book is held 7-10 cm from their eyes. However, frequent reading or writing at this distance can strain the eyes' accommodation, leading to refractive myopia, also known as pseudomyopia. Chronic overaccommodation can lead to inflexible contraction of the ciliary muscles. This overaccommodation leads to increased convergence, which in turn exerts pressure on the extraocular muscles, increasing intraocular pressure and causing congestion. Furthermore, the delicate eye tissues of adolescents gradually stretch the eyeball wall under pressure, lengthening the anterior-posterior axis of the eye. As the condition worsens, true myopia develops.

[0003] Vision therapy means that when early myopia occurs, myopic patients can wear orthoptic glasses when looking at close objects to relieve the eye's adjustment pressure when looking at close objects. Wearing orthoptic glasses to look at close objects has a magnifying effect, but wearing orthoptic glasses to look at distant objects will make it more unclear. Traditional fog glasses are a convex lens. Due to its optical principle, it will be unclear to look at distant objects wearing orthoptic glasses. Existing myopia-reducing glasses use intelligent myopia-reducing glasses that are both corrective and preventive, such as the one disclosed in announcement number CN207380386U. The lower light area is a positive spherical lens plus prism or a positive spherical lens combined with a cylindrical lens plus prism or a negative spherical lens with an additional prism or a negative spherical lens combined with a cylindrical lens with an additional prism. It has a simple structure and is easy to use. The prevention, correction and treatment of myopia can be achieved in the learning process. However, it is difficult to monitor the myopia of people wearing glasses in real time during the wearing process. Especially after a significant change in myopia degree, it is very easy to cause secondary damage to the eyes if the original lenses are still used. In addition, existing glasses mostly use a single plastic buckle structure to fix the lenses, which can easily cause the lenses to slip and fall off. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that it is difficult to monitor and correct the degree of myopia in people with myopia, and to propose a myopia reduction lens that combines correction and prevention.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A myopia chip lens for correcting and preventing myopia, comprising a frame and lenses with diopter values of 100, 125, 150, 175, 200, 225, 250, 300, 325, 350, 375, and 400 respectively. A locking mechanism for fixedly installing the lenses is provided on the frame, and an intelligent control system for obtaining images by simulating the human eye through the lenses and judging the degree of myopia is also provided on the frame.

[0006] Preferably, vertical slots are provided at both the upper and lower ends of the lens.

[0007] Preferably, the locking mechanism includes a U-shaped cavity opened in the frame. A driving worm is rotatably installed in the U-shaped cavity, a traction roller driven by the driving worm is rotatably installed in the U-shaped cavity, a steering swing rod actively pulled by the traction roller is rotatably installed in the U-shaped cavity. A driving gear is integrally connected to the steering swing rod, a reciprocating rack meshing with the driving gear is slidably installed in the U-shaped cavity, an elastic telescopic member is welded in the U-shaped cavity, and a wedge head pin corresponding to the slot and actively pulled by the reciprocating rack is fixedly connected to the elastic telescopic member.

[0008] Preferably, the number of the traction rollers is two, and the two traction rollers are symmetrically arranged at the upper and lower ends of the driving worm.

[0009] Preferably, driven worm gears meshing with the driving worm are key-connected to both of the two traction rollers.

[0010] Preferably, a pressure increasing notch for slidably contacting the wedge head pin is provided in the reciprocating rack.

[0011] Preferably, a first steering pulley and a second steering pulley are fixedly installed in the U-shaped cavity, and a traction rope passing through the first steering pulley and the second steering pulley is fixedly connected between the traction roller and the steering swing rod.

[0012] Preferably, the intelligent control system includes a micro image acquisition module, a clarity analysis algorithm module, a baseline establishment and trend analysis module, an interference elimination module, a reminder and interaction module, and a battery and battery life module.

[0013] Preferably, the micro image acquisition module uses an ultra-small wide-angle camera, the clarity analysis algorithm module is based on the Laplace gradient method and the Fourier transform frequency domain analysis method, the reminder and interaction module uses vibration reminder, and the battery and battery life module uses a micro lithium battery.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The present invention utilizes a locking mechanism on a frame to clamp and limit the position of lenses with stepped diopter. A driving worm drives two driven worm gears to rotate toward or against each other. A traction roller pulls a traction rope to achieve deflection drive of a steering rocker arm. The meshing transmission between a driving gear and a reciprocating rack causes the reciprocating rack to drive a wedge pin elastically supported by an elastic telescopic member, thereby snapping and securing the lens mounted in the frame.

[0015] 2. The present invention sets an intelligent control system on the frame. The smart glasses can realize the automation of the entire process from image clarity monitoring to early warning of myopia degree changes, providing a scientific basis for users to replace lenses in a timely manner.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figures 1-8 A pair of myopia reduction glasses with chip-based correction and prevention functions, comprising a frame 1 and lenses 2 with diopter values ​​of 100, 125, 150, 175, 200, 225, 250, 300, 325, 350, 375, and 400. It should be noted that the lenses 2 are made of suitable materials to meet different scenarios and budget requirements, as follows: Material Advantages Disadvantages Applicable people resin Lightweight (50% lighter than glass), strong impact resistance, and easy to process Average wear resistance (requires coating), easy to scratch The vast majority of people (especially teenagers and daily commuters) Glass Extremely wear-resistant and high light transmittance (theoretically clearer) Heavy (presses the bridge of the nose), poor impact resistance (fragile) People who have extremely high requirements for clarity and use with caution PC Top impact resistance (commonly known as "space film"), lightweight The light transmittance is slightly low and dispersion is likely to occur (the height is obvious) Children (anti-fall), sports enthusiasts More than 90% of the population prefers resin (taking both weight and safety into consideration); PC is chosen for children / sports scenes; glass is only recommended for those with special needs who "need stable degree, pursue extreme wear resistance and can accept the weight."

[0020] Refractive index is also an important indicator for selecting lens 2. Refractive index is the ability of lens 2 to refract light. Under the same degree, the higher the refractive index, the thinner and lighter the lens 2. However, it should be noted that a high refractive index may be accompanied by "more obvious dispersion" (affecting edge clarity) and "higher price": Refractive index Fit (degrees) Features (taking -5.00 degrees as an example) Price range (single lens) 1.50 ≤-3.00 Thicker, heavier, higher Abbe number (low dispersion) 100-300 yuan 1.56 ≤-3.00 10% thinner and 5% lighter than 1.50, high cost performance 200-500 yuan 1.60 -3.00~-6.00 20% thinner and 15% lighter than 1.56, with moderate dispersion 300-800 yuan 1.67 -6.00~-8.00 25% thinner and 20% lighter than 1.60, with slightly more noticeable dispersion 800-1500 yuan 1.74 >-8.00 degrees The thinnest at present, 30% lighter, with more obvious dispersion 1500-4000 yuan In summary: Low myopia (≤-3.00 degrees): Choose 1.56 (cost-effective) or 1.60 (pursuing lightness and thinness); Moderate myopia (-3.00~-6.00 degrees): 1.60 is preferred (balancing thickness, dispersion and price); High myopia (>-6.00 degrees): Choose 1.67 for -6.00~-8.00 degrees (better dispersion control); choose 1.74 for >-8.00 degrees (when thickness has to be compromised).

[0021] A locking mechanism 3 for fixedly installing a lens 2 is provided on a spectacle frame 1. The locking mechanism 3 includes a U-shaped cavity 31 formed in the spectacle frame 1. A driving worm 32 is rotatably installed in the U-shaped cavity 31. It should be noted that one end of the driving worm 32 extending outside the spectacle frame 1 is fixed at an angle by an elastic staple to prevent the driving worm 32 from self-rotating. A traction roller 33 driven by the driving worm 32 is rotatably installed in the U-shaped cavity 31. A steering swing rod 35 movably pulled by the traction roller 33 is rotatably installed in the U-shaped cavity 31. A driving gear 36 is integrally connected to the steering swing rod 35. A reciprocating rack 37 meshing with the driving gear 36 is slidably installed in the U-shaped cavity 31. By driving the steering swing rod 35 to swing left and right, the reciprocating rack 37 makes a linear reciprocating movement in the left and right directions. An elastic telescopic member 39 is welded in the U-shaped cavity 31. A wedge head pin 310 fixedly connected to the elastic telescopic member 39 and corresponding to a card slot is movably pulled by the reciprocating rack 37. In the initial state, the wedge head pin 310 is elastically supported by the elastic telescopic member 39 and stored in the spectacle frame 1. By pressing the wedge head pin 310 with the reciprocating rack 37, the wedge head pin 310 is snap-connected to the card slot in the lens 2 to fix the position of the lens 2 on the spectacle frame 1.

[0022] It should be further noted that: The number of traction rollers 33 is two, and the two traction rollers 33 are symmetrically arranged at the upper and lower ends of the driving worm 32.

[0023] Driven worm wheels 34 meshing with the driving worm 32 are key-connected to both of the two traction rollers 33. Under the driving of the driving worm 32, the two traction rollers 33 rotate towards or away from each other to wind or release a traction rope 311.

[0024] A pressure increasing notch 38 for slidably abutting the wedge head pin 310 is formed in the reciprocating rack 37. By driving the reciprocating rack 37 to move horizontally, the wedge head pin 310 is pressed by the pressure increasing notch 38 to make the wedge head pin 310 stretch and contract vertically.

[0025] A first steering pulley 312 and a second steering pulley 313 are fixedly installed in the U-shaped cavity 31. A traction rope 311 is fixedly connected between the traction roller 33 and the steering swing rod 35 and passes through the first steering pulley 312 and the second steering pulley 313. The first steering pulley 312 and the second steering pulley 313 provide steering support for the traction rope 311 to prevent the traction rope 311 from rubbing against the inner wall of the U-shaped cavity 31.

[0026] The frame 1 is also provided with an intelligent control system 4 for acquiring images through the lens 2 and judging the degree of myopia by imitating the human eye. The intelligent control system 4 includes a micro image acquisition module 41, a clarity analysis algorithm module 42, a baseline establishment and trend analysis module 43, an interference elimination module 44, a reminder and interaction module 45 and a battery and endurance module 46.

[0027] It needs further explanation: The micro-image acquisition module 41 utilizes an ultra-small wide-angle camera. This camera features a 1 / 5-inch sensor, 720P resolution, and a frame rate of 30fps. Its size is ≤5mm×5mm, ensuring it avoids obstructing the view. The ultra-small wide-angle camera is mounted on the inside of the frame 1, near the bridge of the nose or at the front of the temple, with the lens aligned parallel to the user's line of sight (with a deviation of ≤10°), ensuring that the captured image is consistent with what the user is actually observing. It also features a low-power design (standby current ≤1mA), supports adaptive light control, and automatically switches between night vision and bright light modes, facilitating extended standby time.

[0028] The clarity analysis algorithm module 42 is based on the Laplace gradient method and the Fourier transform frequency domain analysis method. The processing logic is to calculate the clarity index every 0.5 seconds, remove the extreme values ​​and take the average value to ensure data stability.

[0029] The baseline establishment and trend analysis module 43 establishes a personal "clarity baseline" through historical data, continuously monitors the index change trend, and determines the vision improvement.

[0030] Initial baseline: When the user first wears the device, collect the clarity index in a stable state for three consecutive days (e.g., sitting and viewing text / screen 3 meters away). The average value is taken as the baseline value (denoted as S0). Dynamic update: The baseline is automatically calibrated once a week (excluding interference factors such as fatigue and abnormal lighting).

[0031] The interference elimination module 44 is used to filter out the clarity changes caused by non-visual factors to avoid misjudgment. The elimination logic is as follows: Environmental interference: The light sensor detects light intensity. If the light intensity is lower than 50 lux (weak light) or higher than 10,000 lux (strong light), data collection is suspended.

[0032] Lens 2 status: An integrated micro infrared sensor detects stains on the surface of Lens 2 (abnormal reflectivity) and prompts the user to clean Lens 2 and re-monitor.

[0033] Eye distance: The ToF sensor measures the distance between the user and the target (for example, within 30 cm is considered close-up eye contact). Only the clarity data of objects viewed at a distance of 5 meters or more is analyzed.

[0034] The reminder and interaction module 45 uses vibration reminders. The temples have built-in micro-vibration motors (frequency 200Hz). Three short vibrations mean "need to be checked", and one long vibration means "it is recommended to replace the lens". It also uses APP linkage to connect to the mobile phone APP via Bluetooth to push detailed reports, including clarity change curves and recommended eye examination time indicators.

[0035] Manual confirmation: Users can mark "Lens cleaned" or "Tested" via the touch buttons on the temples to reset the monitoring status.

[0036] The battery and battery life module 46 uses a micro lithium battery that supports magnetic wireless charging (charging time ≤ 1.5 hours). It can last for 7 days in daily mode (monitoring 8-12 hours per day) and 15 days in power saving mode (collecting data only during sleep at night).

[0037] Please refer to the instruction manual for details Figure 8 , the operation of the intelligent control system 4 is as follows: Initialization phase: After the user puts on the device, the system automatically collects 3 days of basic data to establish a clarity baseline S0.

[0038] Real-time monitoring: The camera captures an image every 0.5 seconds and simultaneously analyzes the clarity index. The interference elimination module 44 filters out invalid data in real time.

[0039] Trend Analysis: Generates a daily "Daily Average Clarity Index" and compares it to a baseline. If the index falls below 85% of the baseline for seven consecutive days, a "Primary Alert" (vibration + app notification) is triggered. Secondary Confirmation: After the primary reminder, the system increases the monitoring frequency for long-distance scenes (over 5 meters) (once every 0.2 seconds). If the index remains below the threshold for three consecutive days, a "Replace Lenses Reminder" (with a clear message: "Your vision may have improved. We recommend an eye exam and lens replacement") will be issued.

[0040] The intelligent control system 4 achieves a non-invasive design, with the module integrated into the glasses, ensuring smooth wear and aesthetics. Highly accurate data, combined with multiple algorithms and interference elimination, reduces false positives. User-friendly feedback eliminates the need for manual operation, with automatic monitoring and reminders.

[0041] But please note that: Regular calibration is required: It is recommended that users re-check their eyes every 3 months and enter the eye test data into the APP to optimize baseline accuracy.

[0042] Applicable scenarios: Mainly for monitoring the reduction of myopia. The algorithm model needs to be adjusted for hyperopia or astigmatism.

[0043] Through the above module design, smart glasses can realize the automation of the entire process from image clarity monitoring to early warning of myopia degree changes, providing a scientific basis for users to replace lenses in a timely manner2.

[0044] Vertical slots are provided at both the upper and lower ends of the lens 2.

[0045] It should be noted that the specific model and specifications of the lens 2 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0046] The present invention can be explained through the following operation mode: The glasses use an ultra-small wide-angle camera to capture images within the user's field of view in real time, providing raw data for clarity analysis and simulating how the human eye observes the scene. The clarity analysis algorithm module 42 calculates the second-order derivative of the grayscale change of the image edge based on the Laplace gradient method and extracts the proportion of high-frequency components of the image based on the Fourier transform frequency domain analysis method; The baseline establishment and trend analysis module 43 establishes a personal "clarity baseline" through historical data, continuously monitors the index change trend, and determines the improvement of vision. When the average clarity index (Sn) for 7 consecutive days is lower than 85% of the baseline (Sn≤0.85×S0), and after eliminating interference such as dirt and wear of lens 2, it is determined that "vision improvement leads to a higher lens power"; When it is determined that the lens 2 needs to be replaced, the reminder and interaction module 45 reminds the user in a multimodal manner; Preliminarily insert the lens 2 of the required power into the frame 1; The driving worm 32 is controlled to rotate, and the two traction rollers 33 are driven to rotate through the driven worm gear 34. The steering rocker 35 is deflected by the traction rope 311. The steering rocker 35 drives the reciprocating rack 37 to move through the driving gear 36. The reciprocating rack 37 applies pressure to the wedge head pin 310 through the booster cut 38, and at the same time causes the elastic telescopic part 39 to contract until the wedge head pin 310 is snap-connected with the slot in the lens 2.

[0047] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
