Description

Technical Field

[0001] This application relates to the field of optical lens technology, and more particularly to a myopia control lens and glasses with a decentered hole. Background Technology

[0002] Currently, myopia control lenses primarily slow myopia progression through optical defocusing or visual signal modulation technologies. However, most existing technologies rely on a central hole design, which involves maintaining a transparent, microstructure-free area at the optical center of the lens to ensure accurate measurements by optometry equipment and clear central vision for the user. Existing myopia control lenses with a central hole not only increase the complexity of lens design and manufacturing but also require special handling of the central hole's position during cutting. The distribution of microstructures around the central hole may become unbalanced due to manufacturing deviations, weakening the inhibitory effect on axial elongation. Furthermore, the central hole may affect the continuity and uniformity of lens defocusing or light scattering effects to some extent, thus negatively impacting the myopia control effect.

[0003] Therefore, there is a need for a myopia control lens with a central hole that avoids the discontinuity of scattered signals caused by the presence of a central hole. Utility Model Content

[0004] In view of this, it is necessary to provide a myopia control lens with a central hole to avoid the discontinuity of scattered signals caused by the presence of a central hole, so as to solve the above problems.

[0005] Embodiments of this application provide a myopia control lens with a decentered aperture, comprising:

[0006] Lens vision zone;

[0007] A functional area covers the optical field of the lens. The functional area is a dot matrix area, a defocus area, or a combination of the two. One of the three—the dot matrix area, the defocus area, or the combination of the two—is set to overlap with the optical field of the lens.

[0008] The dot matrix region has multiple micro-laser dots, the defocus region has multiple microlenses, and the multiple micro-laser dots or the multiple microlenses are distributed throughout the functional region.

[0009] In at least one embodiment of this application, the lens optical region has a first region and a second region, the first region being located in the central region of the lens optical region, and the second region being located around the outer region of the first region, wherein the first region has a circular structure.

[0010] In at least one embodiment of this application, the first region is covered with a first micro laser point, and the second region is covered with a plurality of second micro laser points, the plurality of micro laser points being arranged according to the Fibonacci sequence and conforming to the Fermat spiral, and the spacing between any adjacent micro laser points is equally set.

[0011] In at least one embodiment of this application, the diameters of the first micro laser point and the second micro laser point are equal.

[0012] In at least one embodiment of this application, the first region is covered with a first microlens, and the second region is covered with a plurality of second microlenses, the plurality of second microlenses being arranged radially outward from the first microlens as the center.

[0013] In at least one embodiment of this application, the plurality of second microlenses are arranged in a radial spoke pattern.

[0014] The radial spokes are arranged in layers, with n first spokes, second spokes and third spokes. The n first spokes are all radially radiated uniformly into the second region with the first region as the origin. The second spokes are sandwiched between two first spokes. The third spokes are sandwiched between the first spokes and the second spokes.

[0015] In at least one embodiment of this application, each of the first spokes and the second spokes is arranged with second microlenses that gradually increase in size in the radial direction, and the third spokes are respectively provided with two identical second microlenses arranged in sequence.

[0016] In at least one embodiment of this application, each of the second microlenses on the second spoke is located on the perpendicular bisector of the line connecting the second microlenses of two adjacent first spokes.

[0017] In at least one embodiment of this application, the two are combined such that the dot matrix area and the defocus area overlap.

[0018] Embodiments of this application provide eyeglasses, including any of the myopia control lenses with a decentered aperture as described in any one of the claims.

[0019] The aforementioned decentralized myopia control lens is designed with a lens consisting of a visual area and a functional area. The functional area covers the visual area and can take three forms: a dot matrix area, a defocus area, or a combination of both. The functional area can be chosen to overlap with the visual area according to user needs. In the dot matrix area, multiple micro-laser dots are evenly distributed, while the defocus area is filled with multiple microlenses. This ensures the even distribution of the microstructure throughout the functional area, making the optical control area more stable and effective. Furthermore, it maintains the continuity and uniformity of the optical effect. Light can interact evenly with the micro-laser dots or microlenses throughout the functional area, forming continuous and stable dynamic optical interference signals or defocus signals. This more effectively intervenes in the regulation of axial elongation by visual signals, improving the myopia control effect. Attached Figure Description

[0027] Embodiments of this application provide a myopia control lens with a decentered aperture, comprising:

[0028] Lens vision zone;

[0029] A functional area covers the optical field of the lens. The functional area is a dot matrix area, a defocus area, or a combination of the two. One of the three—the dot matrix area, the defocus area, or the combination of the two—is set to overlap with the optical field of the lens.

[0030] The dot matrix region has multiple micro-laser dots, the defocus region has multiple microlenses, and the multiple micro-laser dots or the multiple microlenses are distributed throughout the functional region.

[0031] The aforementioned decentralized myopia control lens is designed with a lens consisting of a visual area and a functional area. The functional area covers the visual area and can take three forms: a dot matrix area, a defocus area, or a combination of both. The functional area can be chosen to overlap with the visual area according to user needs. In the dot matrix area, multiple micro-laser dots are evenly distributed, while the defocus area is filled with multiple microlenses. This ensures the even distribution of the microstructure throughout the functional area, making the optical control area more stable and effective. Furthermore, it maintains the continuity and uniformity of the optical effect. Light can interact evenly with the micro-laser dots or microlenses throughout the functional area, forming continuous and stable dynamic optical interference signals or defocus signals. This more effectively intervenes in the regulation of axial elongation by visual signals, improving the myopia control effect.

[0032] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] according to Figures 1-3 This application provides a myopia control lens 100 with a decentered hole, including: a lens optical zone 10 and a functional zone 20.

[0034] The functional area 20 covers the optical viewing area 10 of the lens. The functional area 20 is a combination of a dot matrix area 21, a defocus area 22, and the combination thereof. One of the three is arranged to coincide with the optical viewing area 10 of the lens. The dot matrix area 21 has multiple micro laser dots, and the defocus area 22 has multiple microlenses. The multiple micro laser dots or the multiple microlenses are distributed throughout the functional area 20.

[0035] Specifically, the lens's optical zone 10 is the visible area of ​​the lens's effective vision, while the functional zone 20 delays myopia through optical intervention. By selecting the dot matrix zone 21, the defocus zone 22, or combining the dot matrix zone 21 and the defocus zone 22, the lens's optical zone 10 is corrected to achieve the optical function of myopia prevention and control.

[0036] Furthermore, the micro-laser dots within the dot matrix region 21 scatter part of the incident light through the dot matrix structure, creating dynamic optical interference signals around the retina, thereby indirectly interfering with the regulation of axial elongation by visual signals. The microlens array within the defocus region 22 focuses part of the light in front of the retina, forming multiple defocus signals, thereby directly inhibiting axial elongation.

[0037] Furthermore, the functional area 20 covers and overlaps with the lens optical area 10, so that the entire effective visual area of ​​the lens can be fully utilized. Thus, by combining the functional area 20 with the lens optical area 10, the optical function of myopia prevention and control can be achieved while correcting vision, ensuring the continuity and consistency of the lens in optical performance and avoiding optical interference that may occur due to area separation.

[0038] Furthermore, by spreading multiple micro-laser dots in the dot matrix area 21 to fill the entire functional area 20; or by spreading multiple microlenses in the defocus area 22 to fill the entire functional area 20, a continuous optical control area can be formed in the entire functional area 20, thereby eliminating the area of ​​the traditional central hole, ensuring the continuity and uniformity of the lens defocus or light scattering effect, and thus improving the myopia control effect.

[0039] Furthermore, the functional area 20 is equal in area to the lens's optical field area 10, ensuring that the lens provides consistent optical performance throughout the entire effective visual area. This guarantees the optical continuity and stability of the lens and avoids uneven optical performance caused by differences in area.

[0040] In one specific embodiment, the lens optical region 10 has a first region and a second region. The first region is located in the central region of the lens optical region 10, and the second region is located around the outer region of the first region. The first region has a circular structure.

[0041] Specifically, the first zone is located in the central area of ​​the entire lens's optical zone 10, and the second zone surrounds the first zone and can be positioned adjacent to it. The first and second zones are seamlessly connected, eliminating the boundary effect between the traditional central aperture and defocus zone 22 within the functional zone 20. This seamless design allows light to transition smoothly between the first and second zones, avoiding optical interference and visual discomfort caused by the boundary effect. Simultaneously, eliminating the boundary effect makes the optical control of the entire functional zone 20 more continuous and uniform, enabling more effective myopia control and improving the lens's optical performance and user experience.

[0042] Specifically, the first zone is used as the central divergence positioning point within the functional area 20, so that multiple microlenses or multiple micro-laser points can be arranged in a certain pattern and order with the first zone as the origin, ensuring that a uniform and continuous optical control area is formed within the entire functional area 20, thereby generating an effective myopia defocus signal.

[0043] In one specific embodiment, the first region is a circular structure.

[0044] Specifically, the circular structure of the first zone conforms to the natural shape of the central visual area of ​​the human eye, and can accommodate micro-laser points or microlenses that can fill the entire first zone.

[0045] Example 1:

[0046] In one specific embodiment, the first area is covered with a first micro laser point 211, and the second area is covered with a plurality of second micro laser points 212. The plurality of micro laser points are arranged according to the Fibonacci sequence and the Fermat spiral, and the spacing between any adjacent micro laser points is set equally.

[0047] Specifically, the functional area 20 uses a dot matrix area 21 arranged within the lens's optical field 10. Several micro-laser dots within the dot matrix area 21 are arranged according to the Fibonacci sequence and a Fermat spiral. This arrangement maximizes the number of microlenses within a limited space, and ensures that each microlens has sufficient space to avoid overlap. The spacing between any two micro-laser dots is equal. Furthermore, the arrangement of several micro-laser dots according to the Fibonacci sequence and a Fermat spiral has excellent natural aesthetic characteristics, enabling uniform coverage of the microlens within a unit area. This ensures uniformity in the optical control area, avoiding any minor optical deviations and facilitating better control of myopia progression. This prevents minor optical deviations from causing significant differences in usage.

[0048] By setting a first microlaser point 211 with a central origin, multiple second microlaser points 212 are arranged outwards from the first microlaser point 211, following the Fibonacci sequence and conforming to a Fermat spiral. The first microlaser point 211 serves as the central origin of the entire microlens layout in the functional area 20, located within the first zone of the central region of the lens's optical field 10. In the arrangement of the dots, the Fibonacci sequence can be used to determine the spacing between adjacent microlenses. For example, with the first microlaser point 211 as the origin, the distance between the first second microlaser point 212 and the first microlaser point 211 is d, and the distance between the second second microlaser point 212 and the first second second microlaser point 212 is also d. Subsequent microlenses are arranged with equal spacing, and the number of terms in the Fibonacci sequence is used to control the distribution and approximate location range of the microlenses, ensuring that the overall layout maintains a certain regularity and mathematical aesthetic.

[0049] In one specific embodiment, the diameters of the first micro laser point 211 and the second micro laser point 212 are equal.

[0050] Specifically, the micro laser dots have the same diameter, and the light scattering within the dot matrix area 21 is more uniform, avoiding visual interference caused by uneven light scattering due to micro laser dots of different diameters.

[0051] It should be noted that in this embodiment, if multiple micro laser points are arranged according to the Fibonacci sequence and the Fermat spiral, they follow the formula r2=a2θ, that is, the radius increase within a unit angle is proportional to the square root of the angle, thus achieving a constant area density.

[0052] Example 2:

[0053] In one specific embodiment, the first region is covered by a first microlens 221, and the second region is covered by a plurality of second microlenses 222. The plurality of second microlenses 222 are arranged radially outward from the first microlens 221 as the center; the plurality of second microlenses 222 are arranged in a radially spoke-like layer.

[0054] Specifically, the functional area 20 is selected from the defocus area 22 and arranged within the optical field area 10 of the lens. Multiple second microlenses 222 within the defocus area 22 are arranged in a radial spoke-like layered arrangement. Further, in the radial spoke-like layered arrangement, there are n first spokes a, second spokes b, and third spokes c. Each of the n first spokes a radiates radially and uniformly into the second area, with the first area as its origin. The second spokes b are sandwiched between two first spokes a, and the third spokes c are sandwiched between the first spokes a and the second spokes b.

[0055] In one specific embodiment, each of the second microlenses 222 on the second spoke b is located on the perpendicular bisector of the line connecting the second microlenses 222 of the two adjacent first spokes a.

[0056] Furthermore, each of the n first spokes a radiates radially and uniformly to the second region (the outer periphery surrounding the first region) with the first region (located in the central area of ​​the lens's optical zone 10) as its origin. This ensures the continuity and symmetry of optical control from the center to the periphery, allowing light to be reasonably refracted and focused in all directions.

[0057] The second spoke b is sandwiched between two adjacent first spokes a, working in conjunction with the first spokes a to form a denser spoke network. The third spoke c is sandwiched between the first spokes a and the second spoke b, serving a supplementary and balancing function. Furthermore, the first spokes a, the second spokes b, and the third spoke c are all arranged outwards at a certain angle from the first zone as the origin. This creates a continuous transition between the first and second zones, thus eliminating the traditional center hole.

[0058] In one specific embodiment, each of the first spokes a and the second spokes b is arranged with the second microlenses 222 gradually increasing in size in the radial direction, and the third spokes c are respectively provided with two identical second microlenses 222.

[0059] Furthermore, the second spoke b and the first spoke a are arranged with second microlenses 222 whose dimensions gradually increase in the radial direction. As the radial distance increases, the microlens size increases, and their optical control capability is correspondingly enhanced. This arrangement conforms to the changing light control requirements of the human eye from the center to the periphery, and can better adapt to the physiological structure and visual habits of the eyeball. The first microlens 221 in the first region is the microlens with the smallest diameter, thus better controlling the distance of the second microlenses 222, thereby achieving a continuous transition between the first and second regions and eliminating the presence of a traditional central aperture; while in the peripheral region, larger microlenses can more effectively refract distant light, forming a stronger myopic defocus signal. Two identical second microlenses 222 are arranged on the third spoke c, maintaining the consistency and balance of the entire functional area 20.

[0060] Example 3:

[0061] Functional area 20 is configured by overlapping dot matrix area 21 and defocus area 22. Specifically, functional area 20 has multiple micro laser dots arranged in the Fibonacci sequence and conforming to the Fermat spiral, and microlenses arranged in a radial spoke layer.

[0062] Specifically, the dot matrix area 21 and the defocus area 22 in the above embodiments 1 and 2 are overlapped to form multiple microlenses and multiple micro laser points that are interlaced and fill the entire functional area 20.

[0063] This application provides an eyeglass, including a myopia control lens with a decentered hole as described in any one of the claims.

[0064] The eyeglasses made using the aforementioned decentered aperture myopia control lenses have a simple structure and a reasonable design.

[0065] The aforementioned decentralized myopia control lens 100 is designed to consist of a lens optical zone 10 and a functional zone 20. The functional zone 20 covers the lens optical zone 10 and can exist in three forms: a dot matrix zone 21, a defocus zone 22, or a combination of both. The functional zone 20 can be chosen to overlap with the lens optical zone 10 according to user needs. The dot matrix zone 21 is uniformly distributed with multiple micro-laser dots, while the defocus zone 22 is distributed with multiple microlenses. This ensures the even distribution of the microstructure throughout the functional zone 20, making the optical control area more stable and effective. Furthermore, it maintains the continuity and uniformity of the optical effect. Light can interact uniformly with the micro-laser dots or microlenses throughout the functional zone 20, forming continuous and stable dynamic optical interference signals or defocus signals. This more effectively intervenes in the regulation of visual signals on axial elongation, improving the myopia control effect.

[0066] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
