Description

Technical Field

[0001] This invention relates to the field of optical lens technology, and more specifically to a spectacle lens with a hexagonal cylindrical microstructure on its surface. Background Technology

[0002] Peripheral retinal defocus refers to a refractive error that occurs at the periphery of the retina. Myopic patients often exhibit peripheral hyperopic retinal defocus, while hyperopic patients exhibit peripheral myopic retinal defocus. Clinical studies have found that this peripheral hyperopic defocus is one of the key factors promoting the development and progression of myopia.

[0003] Existing technologies also employ defocus designs to control myopia in children and adolescents, such as the peripheral hexagonal honeycomb design and positive defocus microlens design in Xinlexue glasses; and the peripheral ring astigmatism defocus design in Xiaoleyuan glasses. While these defocus designs can achieve some myopia control, astigmatism is directional, and the effect of controlling myopia in a single astigmatic direction is limited. Therefore, there is an urgent need for a lens with multiple astigmatic directions to address the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to provide an eyeglass lens with a hexagonal cylindrical microstructure on its surface, in order to overcome the shortcomings of the prior art.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0006] A spectacle lens with a hexagonal cylindrical microstructure on its surface includes: a lens body, wherein the lens body is divided into a central optical region, a hexagonal cylindrical microstructure distribution region, and a peripheral optical region from the inside out, with its geometric center as the center point. The hexagonal cylindrical microstructure is disposed on the surface of the lens body and includes multiple concentrically arranged regular annular cylindrical microstructures and counter-regular annular cylindrical microstructures. The regular and counter-regular annular cylindrical microstructures are arranged alternately in the radial direction, and the irregular astigmatism generates higher-order perturbations on the incident wavefront of the human eye.

[0007] Furthermore, the conformal ring-shaped cylindrical microstructure includes: multiple hexagonal spherical microstructures and conformal cylindrical microstructures, wherein the spherical microstructures and conformal cylindrical microstructures are arranged alternately.

[0008] Furthermore, the inverted gauge ring cylindrical microstructure includes: multiple hexagonal spherical microstructures and inverted gauge cylindrical microstructures, wherein the spherical microstructures and inverted gauge cylindrical microstructures are arranged alternately.

[0009] Furthermore, the spherical microstructure, the following cylindrical microstructure, and the inverse cylindrical microstructure each have a substrate and a microstructure. The spherical microstructure is used to generate stable refractive power, and the following cylindrical microstructure and the inverse cylindrical microstructure are used to generate stable refractive power and higher-order aberrations.

[0010] Furthermore, the spherical microstructure, the compliant cylindrical microstructure, the inverse cylindrical microstructure, the central optical region, and the peripheral optical region all have the same refractive power.

[0011] Furthermore, each of the aforementioned conformal cylindrical microstructures and inverse cylindrical microstructures provides not entirely the same astigmatism and higher-order aberrations.

[0012] Furthermore, each of the aforementioned conformal cylindrical microstructures and inverse cylindrical microstructures provides the same astigmatism and higher-order aberrations.

[0013] Furthermore, each of the aforementioned spherical microstructures, compliant cylindrical microstructures, and incompatible cylindrical microstructures has the same radial width.

[0014] Furthermore, the central optical region is hexagonal with a circumscribed circle radius of R1; the hexagonal cylindrical microstructure distribution region surrounds the central optical region with a circumscribed circle radius of R2; the peripheral optical region is the area outside the hexagonal cylindrical microstructure distribution region.

[0015] The spectacle lens with a hexagonal cylindrical microstructure on its surface provided by this invention has the following advantages compared with the prior art:

[0016] The spectacle lens of the present invention has a visual correction effect with excellent image quality and stability outside the hexagonal cylindrical microstructure distribution area. In the hexagonal cylindrical microstructure distribution area used for peripheral vision, it alternately introduces radial defocus and higher-order aberrations with and against the rules for the wearing eye. In terms of visual effect, it realizes the coexistence of regular astigmatism and irregular astigmatism in the peripheral field of vision, realizes the low-order and high-order disturbances of the incident wavefront of the peripheral field of vision of the human eye, reduces the imaging quality of the peripheral field of vision of the spectacle lens, and thus improves the effect of myopia prevention and control in adolescents.

[0017] This invention is mainly applicable to adolescents whose myopia is progressing rapidly. It can alternately introduce low-order and high-order aberrations and myopic defocus in the peripheral retinal field of vision. Attached Figure Description

The hexagonal cylindrical microstructure is disposed on the surface of the lens body and includes multiple concentrically arranged regular annular cylindrical microstructures and reverse regular annular cylindrical microstructures. The regular and reverse regular annular cylindrical microstructures are arranged alternately in the radial direction, and the irregular astigmatism generates higher-order perturbations on the incident wavefront of the human eye.

The spherical microstructure 1 is used to generate stable refractive power, and the following cylindrical microstructure 2 and the inverse cylindrical microstructure 3 are used to generate stable refractive power and higher-order aberrations. The refractive power of the spherical microstructure 1, the following cylindrical microstructure 2, the inverse cylindrical microstructure 3, the central optical region 4, and the peripheral optical region is the same. The astigmatism and higher-order aberrations provided by each of the following cylindrical microstructure 2 and the inverse cylindrical microstructure 3 are not exactly the same.

[0027] In a preferred embodiment, each of the spherical microstructure 1, the compliant cylindrical microstructure 2, and the incompatible cylindrical microstructure 3 has the same radial width.

In the hexagonal cylindrical microstructure distribution area used for peripheral vision, it alternately introduces radial defocus and higher-order aberrations with and against the rules for the wearing eye. In terms of visual effect, it realizes the coexistence of regular astigmatism and irregular astigmatism in the peripheral field of vision, realizes the low-order and high-order disturbances of the incident wavefront of the peripheral field of vision of the human eye, reduces the imaging quality of the peripheral field of vision of the spectacle lens, and thus improves the effect of myopia prevention and control in adolescents.
