Description

Technical Field

[0001] The present invention relates to the field of myopia prevention and control technology, and in particular to correction and training integrated lenses and glasses based on retinal signal gradient remodeling. Background Art

[0002] 1. Ordinary single-focal glasses Technical background: Based on spherical / aspherical lens design, it corrects central vision through a single diopter. The technology is mature and low-cost and has been used since the 19th century.

[0003] Advantages: simple structure, strong adaptability, low price, suitable for basic refractive correction.

[0004] Disadvantages: Peripheral light focuses behind the retina, forming "hyperopic defocus". Long-term wearing may accelerate the growth of the eye axis.

[0005] 2. First-line bifocal glasses Technical background: Designed for presbyopia, the lens is divided into two areas, the upper area for distant vision and the lower area for near vision. It originated from the improvement of bifocal lenses in the 19th century and is also used for myopia prevention and control in some optometry stores.

[0006] Advantages: It takes into account both near and far vision, solves the problem of decreased accommodation, and delays the progression of myopia by 30%-50%.

[0007] Disadvantages: obvious aberration, blurred vision at medium distance, dividing line causing "image jump", long wearing adaptation period.

[0008] 3. Defocused glasses Technical background: Based on the "peripheral defocus theory", a defocus signal is formed in front of the retina through a microlens array (such as Xinlexue, Xingqukong, and Aola Lenses) to inhibit the growth of the eye axis.

[0009] Advantages: Clinically proven to delay myopia progression by 30%-60%, non-invasive and easy to wear.

[0010] Disadvantages: Static defocus can easily lead to visual adaptation (the effect decays over time), requires precise pupil distance alignment, and is less effective for children with misaligned eyes. In addition, some defocusing lenses may cause increased astigmatism in children due to uneven defocus distribution.

[0011] 4. Point Diffusion (DOT) Glasses Technical background: Reduce retinal contrast sensitivity through microstructure, simulate natural visual signals, and activate scleral remodeling mechanism.

[0012] Advantages: Reduces the stimulation of high-contrast images on the eye axis and delays the progression of myopia by 40%-60%.

[0013] Disadvantages: Reduced visual quality, relatively simple principle, simple low contrast easily leads to visual adaptation (the effect decays over time); at the same time, for children with insufficient adjustment, the control effect is not ideal. 5. Hilbert Fractal Mirror Technical background: Using fractal geometry and chaotic phase control, the lens surface is designed with nano-scale irregular defocus structure to dynamically stimulate the retina.

[0014] Advantages: Strong anti-adaptability, chaotic light field avoids the attenuation of the effect of traditional defocus lenses, and the axial length delay rate is 47% compared with the single vision group.

[0015] Disadvantages: The image distortion rate is higher than that of traditional defocus lenses, and it is more difficult for children to adapt and their compliance is poor. Summary of the Invention In view of the shortcomings of existing multi-point defocus glasses that are prone to visual adaptation and have an increased risk of astigmatism, point diffusion and low-contrast glasses that are prone to visual adaptation and have poor prevention and control effects for some children, and Hilbert fractal mirrors with high image distortion rate, which make it difficult for children to adapt and have poor compliance; the first purpose of the present invention is to provide a correction and training integrated lens based on a multi-dimensional stereo asymmetric optical signal field. This lens not only has less image distortion and strong anti-adaptation, maintains binocular vision function, but also enhances the management effect of myopia.

[0016] In order to solve the above technical problems, the present invention is solved by the following technical solutions: The integrated correction and training lens based on retinal signal gradient remodeling includes a lens base for correcting vision. The lens base is divided into a central vision correction area and a multi-dimensional three-dimensional asymmetric optical signal field that diffuses outward from the vision correction area. The multi-dimensional three-dimensional asymmetric optical signal field includes 10,000-26,000 independent signal field units with a diameter range of 100-300 μm formed by laser engraving on the concave surface of the lens base, and 400-1500 three-dimensional structural protrusions with a diameter range of 0.5-2 mm formed by convex design. Each three-dimensional structural protrusion is provided with 4-12 independent signal field units.

[0017] Using the above scheme, the vision control principle is as follows: the optical design of the asymmetric optical signal field area will produce wavefront aberration, which will cause the image to have an extremely slight sense of deformation and a short-term sense of blur. As the eyeball receives the blurred signal, the visual nervous system mistakes the signal of a nearby object for the signal of a distant object, thereby inducing the ciliary muscle to relax. After about 2-5 seconds, the blurred image becomes clear. For example, assuming that the corrected visual acuity of the central vision correction area is 1.2, the corrected visual acuity of different optical signal field areas will drop to 0.7~0.8 at the moment of wearing, and as the ciliary muscle relaxes, it will return to 1.0~1.2 after 2-5 seconds. In this way, the lens of the present invention realizes active regulation of the ciliary muscle, so that it can be properly relaxed during long-term close-range eye use, thereby playing a role in delaying the development of myopia. The multi-dimensional three-dimensional structure protrusions and the asymmetric signal field independent units in this design scheme give the lens special structural and optical properties. When the wearer needs to train, they move the eyeglass lenses downward 4 to 15 mm, placing them in a specific training zone. Within this zone, the glasses' three-dimensional structural projections, the lens base, and the asymmetric signal field independent units combine to create an optical environment characterized by a non-fixed gradient blur. While the wearer gazes horizontally at a dedicated visual training chart from a distance of 3 to 5 meters, the ciliary muscles of the eyes must continuously adjust to this non-fixed gradient blurring. This adjustment process is not a traditional foggy vision effect. Instead, through a unique optical design, the ciliary muscles undergo scientific and rational movement, thereby simultaneously improving both accommodative flexibility and relaxation. Simultaneously, as the eyes adapt to this optical stimulation, choroidal blood circulation is improved, increasing blood supply to the choroid, providing more adequate nutrition to the retina, improving aqueous humor microcirculation, effectively maintaining intraocular pressure balance, and further enhancing myopia control. Furthermore, by providing a sufficient number of independent signal field units, the present invention can reduce the degree of clarity gap between the signal field projections, the independent signal field units, and the lens base, effectively managing myopia while maintaining binocular vision.

[0018] Preferably, the multi-dimensional stereoscopic asymmetric optical signal field is divided into a first multi-dimensional stereoscopic asymmetric optical signal field, a second multi-dimensional stereoscopic asymmetric optical signal field and a third multi-dimensional stereoscopic asymmetric optical signal field with gradually increasing blur degree from close to the vision correction area to far away from the vision correction area.

[0019] Using this solution, different levels of blur provide different visual training effects. By dividing the multidimensional, stereoscopic, asymmetric optical signal field into three zones with increasing blur levels, we can meet varying visual training needs. Taking into account different frame sizes and adaptability, the primary training areas are the first multidimensional, stereoscopic, asymmetric optical signal field B1 (first training area) and the second multidimensional, stereoscopic, asymmetric optical signal field B2 (second training area).

[0020] Preferably, the heights of the three-dimensional structural protrusions of the first multi-dimensional asymmetric optical signal field, the second multi-dimensional asymmetric optical signal field and the third multi-dimensional asymmetric optical signal field tend to increase.

[0021] Preferably, the height of the three-dimensional structural protrusion of the first multi-dimensional asymmetric optical signal field is 100-160μm, the height of the three-dimensional structural protrusion of the second multi-dimensional asymmetric optical signal field is 140-200μm, and the height of the three-dimensional structural protrusion of the third multi-dimensional asymmetric optical signal field is 160-300μm.

[0022] With the above solution, as the height of the three-dimensional structure protrusion increases, the interference effect is improved and the blurring degree is correspondingly improved. Different blurring degrees are formed by changing the height of the three-dimensional structure protrusion in the three areas.

[0023] Preferably, the density of the independent signal field units of the first multi-dimensional stereoscopic asymmetric optical signal field, the second multi-dimensional stereoscopic asymmetric optical signal field and the third multi-dimensional stereoscopic asymmetric optical signal field tends to increase.

[0024] Preferably, the density of the independent signal field units of the first multi-dimensional asymmetric optical signal field is in the range of 600-1100 / cm 2 The number ranges from 987 to 1793; the density of the independent signal field units of the second multi-dimensional asymmetric optical signal field ranges from 700 to 1200 per cm 2 The number ranges from 3380 to 5688; the density of the independent signal field units of the third multi-dimensional asymmetric optical signal field ranges from 800 to 1300 per cm 2 , the number ranges from 10360 to 26000.

[0025] Preferably, the vision correction area is located in the center of the lens and is circular with a diameter ranging from 5-7 mm; the first multi-dimensional stereoscopic asymmetric optical signal field is located in the area 4-8 mm from the center of the lens; the second multi-dimensional stereoscopic asymmetric optical signal field is located in the area 8.1-15 mm from the center of the lens; and the third multi-dimensional stereoscopic asymmetric optical signal field is located in the area 15.1-29 mm from the center of the lens.

[0026] Preferably, the three-dimensional structural protrusions are polygonal arc-shaped protrusions, circular arc-shaped protrusions, or elliptical arc-shaped protrusions.

[0027] By adopting the above scheme, the above shapes can all play a preset optical interference effect and achieve the preset visual training effect.

[0028] Preferably, the asymmetric signal field independent unit has an asymmetric C-shaped structure with a sunken center and convex peripheries.

[0029] The second object of the present invention is to provide a pair of glasses having the aforementioned integrated correction and training lenses based on a multi-dimensional stereoscopic asymmetric optical signal field.

[0030] By employing the above technical solution, the present invention achieves significant technical benefits: the lenses, combined with a vision correction zone and a multi-dimensional, stereoscopic, asymmetric optical signal field, enable clear near vision during normal wear and serve as training when displaced downward. When using the glasses for training, the glasses are moved downward 4-8 mm (with the center of the central clear vision area as the reference point). The eyeball is directed to the first multi-dimensional, stereoscopic, asymmetric optical signal field B1 (the first training zone). Due to the raised multi-dimensional structure and the density of the independent units in the asymmetric signal field, the transmittance of the first training zone drops to 90%, generating a 10% retinal blur signal. At this point, combined with a dedicated visual training chart, reading for 5-10 minutes daily while standing 3-5 meters away, the eyeball receives the blur signal, rapidly inducing ciliary muscle relaxation, thereby rapidly relieving the accommodative tension caused by prolonged close-up eye use. This further improves aqueous humor microcirculation, effectively preventing intraocular pressure imbalance and enhancing myopia control. At the same time, since a sufficient number of independent signal field units are provided, the present invention can reduce the degree of clarity separation between the three-dimensional structure protrusions, the independent signal field units and the lens base, thereby playing a role in preventing and controlling myopia while effectively maintaining binocular vision function.

[0031] Once the user can quickly see the sight marks in the first training zone (reaction speed ≤ 1 sight mark per second for the first 7 rows), the training intensity can be increased by lowering the glasses by 8-15 mm. The pupil will be aligned with the second multi-dimensional asymmetric optical signal field B2 (the second training zone). Due to the raised multi-dimensional structure and the density of the independent units in the asymmetric signal field in this area, the light transmittance of the lens in the second training zone drops to 85%, resulting in a 15% retinal blur signal. The training method is the same as for the first training zone, with 5-10 minutes of training per day. The training goal is to achieve a reaction speed of ≤ 1 sight mark per second for the first 7 rows. Once the training goal is achieved, the training duration can be reduced to 3-5 minutes per day.

[0034] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0035] A pair of glasses, comprising a frame and a correction and training integrated lens based on a multi-dimensional stereo asymmetric optical signal field mounted on the frame, referring to Figures 1-6 As shown, the lens includes a lens substrate 1, which is divided into a central vision correction area A and a multi-dimensional three-dimensional asymmetric optical signal field that spreads outward around the vision correction area A.

[0036] The central correction zone is a circular area with a diameter of 5-7mm, accounting for 2%±1% of the total lens area. It utilizes a traditional single-focal design and precisely corrects the wearer's myopia to ensure clear central vision at distances (6 meters and above). For example, if the wearer's myopia is -3.00D, the central correction zone is designed to have a diopter of -3.00D.

[0037] The multi-dimensional asymmetric optical signal field includes 10,000-26,000 asymmetric signal field independent units 2 with a diameter of 100-300 μm formed by laser engraving on the concave surface of the lens substrate 1, and 400-1500 three-dimensional structural protrusions 3 with a diameter of 0.5-2 mm formed by convex design. Figure 2-Figure 3 As shown, in this embodiment, the number of asymmetric signal field independent units is 26,000, with a diameter of 100~200μm, the number of three-dimensional structure protrusions 3 is 708, with a diameter of 1.6mm, the three-dimensional structure protrusions 3 are octagonal arc protrusions or square arc protrusions or circular arc protrusions or elliptical arc protrusions, and the signal field independent unit 2 is an asymmetric C-shape or elliptical pie shape with a sunken center and protrusions around it, etc., and each three-dimensional structure protrusion 3 is provided with 4-12 signal field independent units 2.

[0038] The multi-dimensional asymmetric optical signal field is divided into a first multi-dimensional asymmetric optical signal field B1, a second multi-dimensional asymmetric optical signal field B2, and a third multi-dimensional asymmetric optical signal field B3, each with a gradually increasing degree of blur, from near the vision correction area A to far away from the vision correction area A. The heights of the three-dimensional structural protrusions 3 of the first multi-dimensional asymmetric optical signal field B1, the second multi-dimensional asymmetric optical signal field B2, and the third multi-dimensional asymmetric optical signal field B3 show an increasing trend: the height of the three-dimensional structural protrusions 3 of the first multi-dimensional asymmetric optical signal field B1 is 100-160 μm, and is 134 μm in this embodiment; the height of the three-dimensional structural protrusions 3 of the second multi-dimensional asymmetric optical signal field B2 is 140-200 μm, and is 150 μm in this embodiment; and the height of the three-dimensional structural protrusions 3 of the third multi-dimensional asymmetric optical signal field B3 is 160-300 μm, and is 168 μm in this embodiment. The density of the signal field independent units 2 of the first multi-dimensional stereoscopic asymmetric optical signal field B1, the second multi-dimensional stereoscopic asymmetric optical signal field B2 and the third multi-dimensional stereoscopic asymmetric optical signal field B3 is increasing: the density of the signal field independent units 2 of the first multi-dimensional stereoscopic asymmetric optical signal field B1 is in the range of 600-1100 / cm 2 The number ranges from 987 to 1793; the density of the signal field independent unit 2 of the second multi-dimensional asymmetric optical signal field B2 ranges from 700 to 1200 per cm 2 The number ranges from 3380 to 5688; the density of the signal field independent unit 2 of the third multi-dimensional asymmetric optical signal field B3 ranges from 800 to 1300 per cm 2 , the number ranges from 10360 to 26000.

[0039] A transition zone is provided at the junction of the vision correction area A and the first multi-dimensional asymmetric optical signal field B1 to reduce the degree of visual fragmentation. Figure 1 As shown, the transition area is only laser-engraved with asymmetric signal field independent units 2, and the asymmetric signal field independent units 2 show a trend of gradually increasing in volume and number from the vision correction area A toward the first multi-dimensional stereoscopic asymmetric optical signal field B1.

[0040] The mechanism of myopia is: long-term close-range use of the eyes leads to thinning and ischemia of the choroid, which causes scleral hypoxia, increased collagen degrading enzymes, softening of the sclera, compression of the extraocular muscles, and ultimately lengthening of the eye axis.

[0041] Training purpose: By using glasses equipped with retinal signal gradient reshaping, the adjustment sensitivity and relaxation ability of the ciliary muscle can be enhanced, and the choroidal blood flow can be increased, thereby achieving the goal of effectively controlling the progression of myopia and improving the overall visual function and health of the eyes.

[0042] The training process is as follows: 1. Preparation stage: In a quiet, well-lit and distraction-free indoor environment, place the special visual training chart (see Figure 7 Fix the training chart (as shown) to a wall approximately 3-5 meters in front of the wearer's eyes, ensuring it is level and clearly visible. The wearer should sit or stand upright and adjust the glasses so they rest comfortably on the bridge of their nose.

[0043] 2. Training Begins: Slowly lower the lens 4 to 8 mm into the first training area. Keep your head steady, eyes open, and focus on reading the patterns or characters on the training chart. While gazing, try to maintain a natural gaze, avoiding excessive strain or strain.

[0044] 3. Training duration: Each training session is set to 5 to 10 minutes, and you can perform 1 to 2 training sessions per day based on your personal needs. During training, if you experience symptoms such as eye fatigue or dryness, you can take a short break before continuing training.

[0045] 4. Ending stage: After the training, return the glasses lenses to the normal wearing position, close your eyes and rest for 2 to 3 minutes to allow your eyes to fully relax.

[0046] Training advantages 1. Different from traditional fog vision training, this training program is based on the innovative technology of multi-dimensional stereoscopic convex structure and independent units, forming a non-fixed gradient blur effect, which is more in line with visual physiology, providing a more scientific and effective optical stimulation for the eyes, and breaking through the traditional single blur mode of changing the refractive power by fixing the positive spherical lens.

[0047] 2. The training process is simple and easy and can be carried out at any time in daily life. It only requires a special paper visual training chart. No complicated equipment or professional venues are required, which makes it convenient for the wearer to persist in the long term and more scientific and efficient.

[0048] 3. This training program can not only effectively control the progression of myopia, but also improve the overall visual function and health of the eyes through its positive impact on the ciliary muscle and choroid. It has good application prospects and market value.

[0049] Special Notes: If the difference in the child's eye power is more than 75 degrees, it is recommended to train the left and right eyes separately, and cover them with an eye shield or cover cloth. In this case, the left and right eyes should be trained for 3 minutes each, and then both eyes should be trained for 3 minutes at a time.

[0050] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
