Abstract

This invention relates to the field of myopia control technology, disclosing an integrated correction and training lens and glasses based on retinal signal gradient reshaping, including a lens substrate for vision correction. The lens substrate is divided into a central vision correction zone and a multidimensional, three-dimensional, asymmetric optical signal field extending outward from the vision correction zone. The multidimensional, three-dimensional, asymmetric optical signal field includes 10,000-26,000 independent asymmetric signal field units with diameters ranging from 100-300 μm, laser-engraved on the concave surface of the lens substrate, and 400-1,500 three-dimensional structural protrusions with diameters ranging from 0.5-2 mm. Each three-dimensional structural protrusion has 4-12 independent asymmetric signal field units. This lens does not induce or increase astigmatism due to its own structure, and can alleviate the excessive stimulation of the retina caused by prolonged close-range eye use and abnormal environmental lighting signals, thereby slowing down excessive elongation of the axial length of the eye.

Description

Technical Field

[0001] This invention relates to the field of myopia control technology, and in particular to an integrated lens and glasses for correction and training based on retinal signal gradient reshaping. Background Technology

[0002] I. Ordinary single vision glasses

[0003] Technical background: Based on spherical / aspherical lens design, it corrects central vision with a single refractive power. The technology is mature and low-cost, and has been used since the 19th century.

[0004] Advantages: Simple structure, strong adaptability, low price, suitable for basic refractive correction.

[0005] Disadvantages: Peripheral light focuses behind the retina, creating "hyperopic defocus," and long-term wear may accelerate axial elongation.

[0006] II. One-line bifocal glasses

[0007] Technical background: Designed for presbyopia, the lens is divided into upper and lower sections, with the upper section for distance vision and the lower section for near vision. It originated from the improvement of bifocal lenses in the 19th century and is also used in some optometry stores for myopia control.

[0008] Advantages: It takes into account both near and far vision, solves the problem of decreased accommodation, and slows down the progression of myopia by 30%-50%.

[0009] Disadvantages: Significant aberrations, blurred mid-range field of view, and the dividing line causes "image jumps," requiring a long adaptation period.

[0010] III. Defocus Glasses

[0011] Technical background: Based on the "peripheral defocus theory", a defocus signal is formed in front of the retina through microlens arrays (such as NeoLearning, Star Control, and Aola Lens) to inhibit axial elongation.

[0012] Advantages: Clinically proven to slow myopia progression by 30%-60%, non-invasive and easy to wear.

[0013] Disadvantages: Static defocus is prone to visual adaptation (the effect decays over time), requires precise interpupillary distance alignment, is less effective for some children with misaligned eyes, and some defocus lenses may cause an increase in astigmatism in children due to uneven defocus distribution.

[0014] IV. Dot Diffusion (DOT) Glasses

[0015] Technical background: By reducing retinal contrast sensitivity through microstructures, natural visual signals are simulated, and scleral remodeling mechanisms are activated.

[0016] Advantages: Reduces the stimulation of the eye axis by high-contrast images and slows the progression of myopia by 40%-60%.

[0017] Disadvantages: Decreased visual quality; the principle is relatively simple, and low contrast alone can easily lead to visual adaptation (the effect decays over time); at the same time, children with insufficient accommodation will not have ideal control.

[0018] V. Hilbert Fractal Mirror

[0019] Technical background: By employing fractal geometry and chaotic phase modulation, the lens surface is designed with a nanoscale irregular defocus structure to dynamically stimulate the retina.

[0020] Advantages: Strong adaptability; chaotic light field avoids the effect degradation of traditional defocus lenses; axial length descent rate is 47% compared to single-lens reflex lenses.

[0021] Disadvantages: The image distortion rate is relatively higher than that of traditional defocus lenses, making it more difficult for children to adapt and resulting in poorer compliance. Summary of the Invention

[0022] To address the shortcomings of existing multi-point defocus glasses, which are prone to visual adaptation and increase the risk of astigmatism, and point diffusion low-contrast glasses, which are also prone to visual adaptation and have poor control effects for some children, as well as the high image distortion rate of Hilbert fractal lenses, which are difficult for children to adapt to and have poor compliance, the primary objective of this invention is to provide a correction and training lens based on a multi-dimensional stereoscopic asymmetric optical signal field. This lens not only has less image distortion and strong resistance to adaptation, but also maintains binocular visual function and enhances the management effect of myopia.

[0023] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0024] The integrated correction and training lens based on retinal signal gradient reshaping includes a lens substrate for vision correction. The lens substrate is divided into a central vision correction zone and a multidimensional stereoscopic asymmetric optical signal field that diffuses outward around the vision correction zone. The multidimensional stereoscopic asymmetric optical signal field includes 10,000-26,000 independent signal field units with a diameter of 100-300 μm formed by laser engraving on the concave surface of the lens substrate, and 400-1,500 three-dimensional structural protrusions with a diameter of 0.5-2 mm formed on the convex surface. Each three-dimensional structural protrusion is provided with 4-12 independent signal field units.

[0025] The vision control principle using the above scheme is as follows: The optical design of the asymmetric optical signal field region generates wavefront aberration, causing extremely slight distortion and brief blurring of the image. As the eye receives the blurred signal, the visual nervous system misinterprets the signal of a near object as a signal of a distant object, thereby inducing the ciliary muscle to relax. After approximately 2-5 seconds, the blurred image becomes clear. For example, assuming the corrected visual acuity in the central vision correction zone is 1.2, the corrected visual acuity in different optical signal field regions will drop to 0.7-0.8 immediately upon wearing, and then recover to 1.0-1.2 after 2-5 seconds as the ciliary muscle relaxes. In this way, the lens of this invention achieves active adjustment of the ciliary muscle, allowing it to relax appropriately during prolonged close-range eye use, thereby delaying the progression of myopia. The multi-dimensional three-dimensional protrusion and independent asymmetric signal field unit in this design scheme give the lens special structural and optical properties. When the wearer needs to train, the lenses are moved downwards by 4 to 15 millimeters to enter a specific training area. Within this area, the three-dimensional convex structure of the glasses, the lens base, and the asymmetric signal field independent units combine to form an optical environment with non-fixed gradient blurring characteristics. At this time, the wearer gazes horizontally at a dedicated visual training chart from 3 to 5 meters away. The ciliary muscle of the eye needs to constantly adjust to adapt to this non-fixed gradient blurring optical stimulus. This adjustment process is not a traditional fogging effect, but rather, through a unique optical design, it prompts the ciliary muscle to perform scientific and reasonable movements, thereby simultaneously improving accommodative flexibility and relaxation ability. Simultaneously, as the eye adapts to this optical stimulus, choroidal blood circulation is improved, increasing blood supply to the choroid, providing more sufficient nutrition to the retina, improving aqueous humor microcirculation, effectively maintaining intraocular pressure balance, and further enhancing myopia control. Furthermore, due to the sufficient number of signal field independent units, this invention can reduce the degree of sharpness separation between the signal field convex structure, the signal field independent units, and the lens base, achieving myopia management while maintaining binocular visual function.

[0026] Preferably, the multidimensional stereo asymmetric optical signal field is divided into a first multidimensional stereo asymmetric optical signal field, a second multidimensional stereo asymmetric optical signal field, and a third multidimensional stereo asymmetric optical signal field, with the degree of blur gradually increasing from the area close to the vision correction area to the area far away from the vision correction area.

[0027] Using the above scheme, different degrees of blur produce different visual training effects. By setting the multidimensional stereo asymmetric optical signal field into three regions with progressively increasing blur levels, different visual training needs can be met. Considering different frame sizes and adaptability, the main training areas are the first multidimensional stereo asymmetric optical signal field B1 (first training area) and the second multidimensional stereo asymmetric optical signal field B2 (second training area).

[0028] Preferably, the height of the three-dimensional structure protrusions of the first, second, and third multidimensional asymmetric optical signal fields increases progressively.

[0029] Preferably, the height of the three-dimensional protrusion of the first multidimensional asymmetric optical signal field is 100-160 μm, the height of the three-dimensional protrusion of the second multidimensional asymmetric optical signal field is 140-200 μm, and the height of the three-dimensional protrusion of the third multidimensional asymmetric optical signal field is 160-300 μm.

[0030] Using the above scheme, as the height of the three-dimensional structure protrusion increases, the interference effect is enhanced, and the ambiguity is correspondingly improved. Different degrees of ambiguity are formed by the change in the height of the three-dimensional structure protrusion in the three regions.

[0031] Preferably, the density of the independent signal field units in the first, second, and third multidimensional asymmetric optical signal fields shows an increasing trend.

[0032] Preferably, the density of independent signal field units in the first multidimensional stereo asymmetric optical signal field ranges from 600 to 1100 units / cm². 2 The number ranges from 987 to 1793; the density of independent signal field units in the second multidimensional asymmetric optical signal field ranges from 700 to 1200 units / cm². 2 The number ranges from 3380 to 5688; the density of independent signal field units in the third multidimensional stereo asymmetric optical signal field ranges from 800 to 1300 units / cm². 2 The number ranges from 10,360 to 26,000.

[0033] Preferably, the vision correction area is located in the center of the lens and is circular with a diameter range of 5-7mm; the first multidimensional stereo asymmetric optical signal field is located in the region 4-8mm from the center of the lens; the second multidimensional stereo asymmetric optical signal field is located in the region 8.1-15mm from the center of the lens; and the third multidimensional stereo asymmetric optical signal field is located in the region 15.1-29mm from the center of the lens.

[0034] Preferably, the three-dimensional protrusion is a polygonal arc-shaped protrusion, a circular arc-shaped protrusion, or an elliptical arc-shaped protrusion.

[0035] By adopting the above scheme, the above shapes can all achieve the preset optical interference effect and achieve the preset visual training effect.

[0036] Preferably, the independent unit of the asymmetric signal field has an asymmetric C-shaped structure with a sunken center and a raised periphery.

[0037] The second objective of this invention is to provide eyeglasses having the aforementioned integrated correction and training lens based on a multidimensional stereoscopic asymmetric optical signal field.

[0038] This invention, employing the above technical solution, possesses significant technical effects: the lens combines a vision correction zone and a multidimensional asymmetric optical signal field. Under normal wear, it enables clear near vision, while downward movement serves a training function. When using the glasses for training, moving them downwards by 4-8mm (with the center of the central clear vision zone as a reference) causes the eyeball to correspond to the first multidimensional asymmetric optical signal field B1 (first training zone). Due to the degree of protrusion of the multidimensional structure and the density of independent units in the asymmetric signal field in this area, the light transmittance of the first training zone decreases to 90%, generating a 10% retinal blur signal. At this time, combined with a dedicated vision training chart, standing 3-5 meters away, reading for 5-10 minutes daily, the eyeball receives the blur signal, rapidly inducing ciliary muscle relaxation. This quickly relaxes the accommodative tension caused by prolonged close-range eye use, further improving the microcirculation of the aqueous humor, effectively preventing intraocular pressure imbalance, and enhancing myopia control. Meanwhile, by setting up a sufficient number of independent signal field units, the present invention can reduce the degree of separation in clarity between the three-dimensional structure protrusion, the independent signal field units and the lens substrate, thereby effectively maintaining binocular visual function while controlling myopia.

[0039] Once the user can quickly and clearly see the targets in the first training area (reaction speed of the first 7 rows of targets ≤ 1 per second), the training intensity can be increased by lowering the glasses by 8-15 mm. The pupil then corresponds to the second multidimensional asymmetric optical signal field B2 (second training area). Due to the increased protrusion of the multidimensional structure and the density of independent units in the asymmetric signal field in this area, the light transmittance of the lens in the second training area decreases to 85%, resulting in a 15% retinal blur signal. The training method is the same as for the first training area, with 5-10 minutes of training per day. The training goal is: reaction speed of the first 7 rows of targets ≤ 1 per second. After achieving this goal, the training time can be shortened to 3-5 minutes per day. Attached Figure Description

Detailed Implementation

[0048] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0049] A pair of eyeglasses includes a frame and a correction and training lens mounted on the frame, based on a multidimensional stereoscopic asymmetric optical signal field, for reference. Figures 1-6 As shown, the lens includes a lens substrate 1, which is divided into a central vision correction zone A and a multidimensional asymmetric optical signal field that diffuses outward around the vision correction zone A.

[0050] The central vision correction zone is a circle with a diameter of 5-7mm, accounting for 2%±1% of the total lens area. It adopts a traditional monofocal design and accurately corrects the wearer's myopia to ensure clear central vision when looking at distances (6 meters and above). For example, if the wearer's myopia is -3.00D, the refractive power of the central vision correction zone is designed to be -3.00D.

[0051] The multidimensional asymmetric optical signal field comprises 10,000-26,000 independent asymmetric signal field units 2, with diameters ranging from 100-300 μm, laser-engraved on the concave surface of the lens substrate 1, and 400-1,500 three-dimensional protrusions 3, with diameters ranging from 0.5-2 mm, formed by convex construction. Combined with... Figures 2-3As shown, in this embodiment, there are 26,000 asymmetric signal field independent units with a diameter of 100-200 μm, and 708 three-dimensional protrusions 3 with a diameter of 1.6 mm. The three-dimensional protrusions 3 are octagonal arc protrusions, square arc protrusions, circular arc protrusions, or elliptical arc protrusions. The signal field independent units 2 are asymmetric C-shaped or elliptical disc-shaped with a central depression and surrounding protrusions. Each three-dimensional protrusion 3 is provided with 4-12 signal field independent units 2.

[0052] The multidimensional stereo asymmetric optical signal field is divided into three progressively increasing levels of blur: a first multidimensional stereo asymmetric optical signal field B1, a second multidimensional stereo asymmetric optical signal field B2, and a third multidimensional stereo asymmetric optical signal field B3, moving from near the vision correction area A to far away from it. The height of the three-dimensional protrusions 3 in the first, second, and third multidimensional stereo asymmetric optical signal fields B1, B2, and B3 increases progressively: the height of the protrusions 3 in the first multidimensional stereo asymmetric optical signal field B1 is 100-160 μm (134 μm in this embodiment); the height of the protrusions 3 in the second multidimensional stereo asymmetric optical signal field B2 is 140-200 μm (150 μm in this embodiment); and the height of the protrusions 3 in the third multidimensional stereo asymmetric optical signal field B3 is 160-300 μm (168 μm in this embodiment). The density of signal field independent units 2 in the first multidimensional asymmetric optical signal field B1, the second multidimensional asymmetric optical signal field B2, and the third multidimensional asymmetric optical signal field B3 shows an increasing trend: the density of signal field independent units 2 in the first multidimensional asymmetric optical signal field B1 ranges from 600 to 1100 units / cm². 2 The number ranges from 987 to 1793; the density of the independent signal field units 2 of the second multidimensional asymmetric optical signal field B2 ranges from 700 to 1200 units / cm². 2 The number ranges from 3380 to 5688; the density of the independent signal field units 2 of the third multidimensional asymmetric optical signal field B3 ranges from 800 to 1300 units / cm². 2 The number ranges from 10,360 to 26,000.

[0053] A transition zone is provided at the boundary between the vision correction zone A and the first multidimensional stereoscopic asymmetric optical signal field B1 to reduce the degree of visual fragmentation. (Refer to...) Figure 1 As shown, the transition zone is laser-engraved with independent asymmetric signal field units 2, and the independent asymmetric signal field units 2 show a trend of gradually increasing volume and number from the vision correction zone A to the first multidimensional stereoscopic asymmetric optical signal field B1.

[0054] The mechanism of myopia is as follows: prolonged close-range use of the eyes leads to thinning and ischemia of the choroid, causing scleral hypoxia, increased collagen degradation enzymes, softening of the sclera, compression of extraocular muscles, and ultimately elongation of the axial length of the eye.

[0055] Training objective: By using glasses equipped with retinal signal gradient reshaping, the training aims to enhance the ciliary muscle's accommodative sensitivity and relaxation ability, promote increased choroidal blood flow, and thereby effectively control myopia progression, improving overall visual function and eye health.

[0056] The training process is as follows:

[0057] 1. Preparation stage: In a quiet, well-lit, and undisturbed indoor environment, place the special visual training chart (see...) Figure 7 (As shown) Fix the glasses to a wall approximately 3-5 meters in front of the wearer's eyes, ensuring the training chart is horizontal and clearly visible. The wearer should maintain an upright sitting or standing posture and adjust the glasses to comfortably rest on the bridge of their nose.

[0058] 2. Training begins: The wearer slowly moves the glasses lenses downwards by 4 to 8 millimeters, entering the first training area. Keeping the head stable, eyes naturally open, focus attention on gazing at and reading the patterns or characters on the training chart. During the gazing process, try to maintain a natural eye position, avoiding excessive force or tension.

[0059] 3. Training duration: Each training session should last 5 to 10 minutes, and you can train 1 to 2 times a day depending on your individual situation. If you experience eye fatigue, dryness, or other discomfort during training, you can take a short break before continuing.

[0060] 4. Finishing stage: After training, return the glasses to their normal wearing position, close your eyes and rest for 2 to 3 minutes to allow your eyes to fully relax.

[0061] Training advantages

[0062] 1. Unlike traditional fog vision training, this training program is based on innovative technology of multi-dimensional stereoscopic convex structure and independent units, which forms a non-fixed gradient blur effect, which is more in line with visual physiology and provides the eyes with more scientific and effective optical stimulation. It breaks through the traditional single blur mode of changing the refractive power by fixing positive spherical lenses.

[0063] 2. The training process is simple and easy to carry out, and can be done anytime in daily life. It only requires the use of a paper-based vision training chart. No complicated equipment or professional venue is needed, making it convenient for wearers to persist in the long term, and making it more scientific and efficient.

[0064] 3. This training program can not only effectively control the development of myopia, but also improve the overall visual function and health of the eyes by positively influencing the ciliary muscle and choroid, thus having good application prospects and market value.

[0065] Special Note:

[0066] If the difference in prescription between a child's two eyes exceeds 75 degrees, it is recommended to train each eye separately, using an eye shield or occlusion cloth. In this case, train each eye separately for 3 minutes, and then train both eyes simultaneously for 3 minutes.

[0067] 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 embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
