Description

Technical Field

[0001] This utility model relates to a snail-type light scattering point lens, belonging to the field of optical lens technology. Background Technology

[0002] Currently, mainstream myopia intervention programs mainly fall into three categories: 1. Environmental intervention programs: Ensuring sufficient outdoor activity time serves as a fundamental measure to prevent the onset of myopia and slow its progression. While this method is easy to implement, its effectiveness is limited by individual behavioral habits and objective conditions. 2. Pharmacological intervention programs: These primarily utilize non-selective muscarinic receptor antagonist eye drops (such as atropine). Existing research indicates that pharmacological intervention programs have the following problems: First, the mechanism of action is not fully understood; second, the efficacy is dose-dependent, accompanied by significant adverse reactions such as cycloplegia and photophobia; and finally, the safety of long-term use still needs further verification. 3. Optical intervention programs: This program has a unique advantage: it directly slows the progression of myopia while correcting refractive errors. Its mechanism of action is based on the theory of visual guidance: eye growth depends on the precise control of contrast and defocus signals; abnormal visual experience disrupts the refractive development process; and existing technologies mostly achieve intervention by inducing myopic defocus in the peripheral retina.

[0003] However, existing light scattering lenses have several technical drawbacks: firstly, the sharp boundary between the central region and the scattering area makes them prone to optical interference; secondly, the highly regular distribution of scattering points makes them prone to moiré fringe interference; and thirdly, the distribution of haze values ​​does not match the sensitivity of the retina, resulting in problems such as local scattering blind spots or over-scattering areas. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a snail-type light scattering dot lens.

[0005] The snail-type light scattering dot lens provided in this application adopts the following technical solution: A snail-shaped light scattering point lens includes a lens body with a circular central region having a diameter of 4-5 mm. A light scattering functional area is provided on the outer periphery of the central region, and the light scattering functional area is distributed around the outer periphery of the central region, including multiple snail-shaped light scattering points.

[0006] Through the aforementioned technical solution, this application prioritizes central vision and achieves full coverage of peripheral functions by employing a layered structure of a circular central region and peripheral light-scattering functional areas. This application uses an independent circular central region as the basic imaging area without scattering function, strictly matching the optical requirements of central vision in the human eye to ensure clear signal reception in the central macula. Simultaneously, light-scattering functional areas are distributed around the periphery of the central region, forming a layered structure of "clear center, scattering periphery," avoiding optical abrupt changes between the central and scattering areas while achieving full coverage of the peripheral region, ensuring that every peripheral field of vision receives the scattered signal and eliminating the scattering blind spots of traditional lenses. A transparent aperture is reserved in the center of the independent central region to ensure central vision, and thousands of micro-dots distributed around it achieve soft light control. Furthermore, the light-scattering points used in this application employ a special distribution structure of multiple snail-shaped light-scattering points. This design, by changing the way visual signals are processed, opens up a completely new path for myopia optical intervention, achieving a high degree of unity between corrective function and prevention effectiveness.

[0007] Furthermore, the randomness of the snail-shaped light scattering points is 0.11, and the point spacing is 0.39 mm.

[0008] Through the above technical solution, this application clarifies the randomness and spacing of the snail-shaped light scattering points. Traditional lenses often use a regular arrangement of scattering points, which easily forms moiré fringes with regular structures in the environment, producing an interference pattern of alternating light and dark, affecting visual comfort. This application uses a specific randomness arrangement to break the regularity of the scattering points, avoiding resonance interference with environmental structures. When the wearer observes regular environments such as screens and windows, no obvious interference patterns will appear, resulting in a more natural and smooth visual experience. Prolonged use of the eyes is less likely to cause visual fatigue, effectively protecting eye health. Regarding the stability of the scattering effect, the uniform dot spacing ensures that the scattered signal is evenly distributed throughout the entire peripheral area, avoiding the problem of "localized excessive blurring and localized insufficient failure" common in traditional lenses.

[0009] Furthermore, the diameter of the snail-shaped light scattering point gradually increases from the inside to the outside, and each snail-shaped light scattering point includes several microstructure points, the number of which increases with the diameter of the light scattering point.

[0010] Through the above technical solution, this application achieves a synchronous increase in scattering intensity as retinal sensitivity decreases by increasing the diameter of the scattering point and the number of microstructure points. The scattering in the near-peripheral area is gentle and does not interfere with vision, while the scattering in the far-peripheral area is sufficient and functional. This completely solves the problem of poor local adaptability caused by the one-size-fits-all design of traditional lenses, making the lens more in line with the physiological characteristics of the human eye. When wearing the lens, the eye does not need to frequently adjust to adapt to changes in scattering, further reducing visual fatigue.

[0011] Furthermore, the light scattering point includes six rings of light scattering points with different diameters. The innermost ring has a diameter of 0.05 mm, the second ring has a diameter of 0.07 mm, the third ring has a diameter of 0.10 mm, the fourth ring has a diameter of 0.14 mm, the fifth ring has a diameter of 0.16 mm, and the sixth ring, extending to the edge of the lens, has a diameter of 0.20 mm.

[0012] Through the above technical solution, this application precisely divides the diameter of the light scattering point into concentric circles. Through a multi-concentric gradient design, it achieves a smooth transition in scattering intensity and precise coverage of the entire periphery. This application divides the scattering area into multiple concentric circles, each corresponding to a specific retinal region. The inner circle corresponds to the near-peripheral high-sensitivity area and has the smallest diameter to control scattering intensity. As the number of concentric circles increases, the diameter gradually increases to adapt to the peripheral region where retinal sensitivity gradually decreases. The outermost circle extends to the lens edge, ensuring no blind spots in scattering function. This precise multi-concentric division allows the scattering intensity to change slowly with each concentric circle, avoiding optical abrupt changes, while simultaneously achieving a precise match between the scattering intensity of each circle and the sensitivity of the corresponding retinal region. Regarding visual transition, the gradual increase in the diameter of the multiple concentric circles allows the scattering intensity to change gradually from the inside out. When the wearer's gaze switches between the central area and the peripheral scattering area, or between different concentric scattering areas, they will not experience significant changes in vision. This completely eliminates the dizziness and visual distortion caused by the abrupt transitions between concentric circles in traditional lenses, significantly reducing the difficulty of adaptation, making it especially suitable for first-time users of light scattering lenses. In terms of functional coverage accuracy, each ring diameter corresponds to a specific retinal area, ensuring that the near peripheral area has no blurring, the middle peripheral area has moderate scattering, and the far peripheral area has sufficient scattering. There are no scattering blind spots in the entire periphery, and the light adjustment function coverage is more comprehensive, providing precise light adjustment for the needs of different retinal areas.

[0013] Furthermore, the fog visibility of the light scattering point gradually changes from light to dark from the inside to the outside, and the change in fog visibility increases with the diameter of the light scattering point.

[0014] Through the aforementioned technical solution, this application achieves a gradual increase in fog intensity from the inside out, synchronized with the diameter increase. This prevents blurring caused by scattering from affecting judgment during daily activities, especially in indoor close-range vision scenarios, allowing for clear perception of environmental details and avoiding the overall blurring caused by excessive fog intensity in traditional lenses. From a scattering perspective, the combined effect of dense fog intensity on the outer ring and a large-diameter scattering point significantly enhances the scattering intensity in the far peripheral region, effectively regulating peripheral incident light and meeting light scattering requirements. This solves the problem of insufficient far peripheral scattering caused by excessively shallow fog intensity in traditional lenses. Furthermore, the gradual fog intensity design and diameter increase work synergistically to further optimize the transition of optical performance, making the eye's adaptation to scattering changes smoother and reducing visual fatigue caused by sudden changes in fog intensity, thus balancing functional practicality and wearing experience.

[0015] Furthermore, the light scattering point with the largest diameter contains 35-45 microstructure points.

[0016] Through the above technical solution, this application clarifies the range of the number of microstructure points contained in the largest diameter light scattering point. Regarding the stability of scattering performance, a reasonable range of numbers ensures that the scattering efficiency of the largest diameter scattering point is always within the optimal range. This prevents the lens from experiencing uneven scattering due to insufficient numbers or excessive scattering due to excessive numbers, allowing it to stably perform its light-modulating function in the far-peripheral region. It avoids affecting the overall function due to deviations in the number of microstructure points, ensuring consistent lens performance. In terms of production feasibility, the quantity range design adapts to process fluctuations in actual production, eliminating the need for an absolutely fixed quantity. This reduces production precision requirements, decreases the scrap rate due to insufficient quantity, improves production efficiency, and ensures product quality stability. Furthermore, a sufficient number of microstructure points enhances the structural strength of the largest diameter scattering point. Since scattering points in the far-peripheral region are easily worn due to their large size, more microstructure points form a more stable structure, reducing the impact of wear on scattering function and extending the lens's lifespan.

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. This application employs a layered structure of a circular central region and peripheral light-scattering functional areas to prioritize central vision while achieving full coverage of peripheral functions. The independent circular central region serves as the basic imaging area without scattering function, strictly matching the optical requirements of central vision in the human eye to ensure clear signal reception in the central macula. Simultaneously, light-scattering functional areas are distributed around the periphery of the central region, forming a layered structure of "clear center, scattering periphery." This avoids optical abrupt changes between the central and scattering areas while achieving full coverage of the peripheral region, ensuring that every peripheral field of vision receives the scattered signal and eliminating the scattering blind spots of traditional lenses. A transparent aperture is reserved in the center of the independent central region to ensure central vision, combined with thousands of micro-dots distributed around it to achieve soft light control. Furthermore, the light-scattering points used in this application employ a special distribution structure of multiple snail-shaped light-scattering points. This design, by altering the visual signal processing method, opens up a new path for myopia optical intervention, achieving a high degree of unity between corrective function and prevention effectiveness.

[0018] 2. The snail-shaped light scattering point design of this application optimizes the scattering effect from multiple dimensions, avoiding visual problems caused by uneven distribution or single parameters in traditional scattering lenses. On the one hand, the random arrangement of scattering points breaks the interference such as moiré fringes that are easily generated by regular layouts, ensuring that there are no obvious interference patterns when viewing objects, resulting in a more natural visual experience. On the other hand, the gradient change in the diameter of the scattering points and the degree of fogging precisely adapts to the sensitivity differences of the retina from the inside to the outside. The weaker scattering effect in the inner circle avoids causing blurred vision in high-sensitivity areas, while the stronger scattering effect in the outer circle meets the light adjustment needs of low-sensitivity areas, forming a "gradient transition" scattering environment. This design eliminates the need for frequent adjustments by the eyes to adapt to uneven scattering signals, effectively reducing initial discomfort such as dizziness and visual distortion, and improving the comfort of long-term wear.

[0019] 3. The micro-structural point splicing process and parameter co-design of the lens in this application endow it with excellent structural stability and scene adaptability. The splicing of micro-structural points adopts a rounded transition treatment, which not only enhances the structural strength of individual scattering points, but also avoids optical diffraction interference caused by sharp-angle structures, ensuring that the scattering signal remains stable and free from stray light interference in different lighting environments such as strong light and low light. At the same time, the coordinated changes in the diameter of the scattering points, the fogging degree, and the number of micro-structural points allow the lens to maintain good visual effects and light adjustment in scenarios such as close-range reading, mid-range office work, and long-range outdoor observation. Compared with the limitation of traditional light scattering lenses that are only suitable for specific lighting environments, this lens significantly expands the boundaries of its application scenarios, meets diverse eye needs, and significantly enhances its practical value.

Explanation of reference numerals in the attached diagram: 1. Lens body; 11. Central area; 12. Light scattering functional area; 121. Light scattering point. Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0022] like Figure 1 A snail-shaped light scattering point lens includes a lens body 1, which is made of a circular optical lens substrate. The geometric center and optical center of the lens body 1 are completely coincident, and all functional areas are concentrically distributed with the coincident center as the center, ensuring the symmetrical optical performance of the lens and avoiding visual deviation caused by structural offset.

[0023] The central region 11 of the lens body 1 is the basic imaging core component of the lens, located at the very center of the lens body 1, with a diameter of 4-5 mm. The light scattering functional area 12 is continuously distributed around the outer periphery of the central region 11, covering the entire area of ​​the lens body 1 except for the central region 11. It consists of multiple rings of snail-shaped light scattering points 121, with each ring of light scattering points 121 arranged in concentric circles with the center of the lens as the center. Each snail-shaped light scattering point 121 adopts a spiral protrusion structure, with a spiral texture depth of 0.02-0.05 mm and a width of 0.01-0.03 mm, and the overall outline is a smooth snail shape. Each light scattering point 121 is spliced ​​together from several micro-structure points, which are circular protrusions with a diameter of 0.005-0.01 mm. The splicing points are rounded to avoid optical diffraction interference caused by sharp angle structures. The randomness of the arrangement of all snail-shaped light scattering points 121 is strictly controlled to 0.11; the center-to-center distance between two adjacent snail-shaped light scattering points 121 is uniformly 0.39 mm.

[0024] The light scattering functional region 12 is divided into 6 concentric layers according to the diameter of the scattering point, nested sequentially from the inside out. The correspondence between the position of each layer and its diameter is as follows: The first ring (innermost ring): adjacent to the outer edge of the central region 11, the snail-shaped light scattering points 121 in this ring have a diameter of 0.05mm, and each scattering point is composed of 8-10 small microstructure points spliced ​​together; The second ring: located on the outer periphery of the first ring, with a radial distance from the first ring equal to the distance between the scattering points 121 (0.39 mm). The diameter of the scattering points in this ring is 0.07 mm, and each scattering point is composed of 12-15 small microstructure points. The third ring: located on the outer perimeter of the second ring, with a radial spacing of 0.39 mm and a scattering point diameter of 0.10 mm. Each scattering point is composed of 18-22 small microstructure points. The fourth ring: located on the outer perimeter of the third ring, with a radial spacing of 0.39 mm and a scattering point diameter of 0.14 mm. Each scattering point is composed of 25-28 small microstructure points. The fifth ring: located on the outer perimeter of the fourth ring, with a radial spacing of 0.39 mm and a scattering point diameter of 0.16 mm. Each scattering point is composed of 30-33 small microstructure points. The sixth ring extends from the outer periphery of the fifth ring to the edge of the lens body 1. The diameter of the scattering point is stable at 0.20mm. Each scattering point is composed of 35-45 small microstructure points. The spiral texture depth and width of the scattering points in this ring reach their maximum values ​​to ensure the strongest light scattering effect.

[0025] A haze gradient is achieved by adjusting the spiral pattern density and protrusion height of the snail-shaped light scattering points 121. The spiral patterns of the small-diameter scattering points in the inner circle (0.05-0.10mm) are sparse and the protrusion height is low, resulting in shallow haze. The spiral patterns of the large-diameter scattering points in the outer circle are dense and the protrusion height is high, resulting in deep haze. Moreover, the change in haze is completely synchronized with the increase in the diameter of the scattering points, forming a continuous haze gradient of "shallow inside and deep outside".

[0026] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
