Description

Technical Field

[0001] This invention belongs to the field of optical lens design and processing technology, and particularly relates to a spectacle lens with a hexagonal spherical microstructure on the front surface and a low-contrast design on the rear surface. Background Technology

[0002] Peripheral defocus refers to refractive errors occurring at the periphery of the retina. Myopic patients often exhibit peripheral hyperopic defocus, while hyperopic patients exhibit peripheral myopic defocus. Clinical studies have found that this peripheral hyperopic defocus is a key factor promoting the development and progression of myopia. Adding a microlens array to the peripheral region of the lens is one way to introduce defocus at the lens periphery. This type of lens utilizes the refractive power of the microlenses to alter the refractive structure at the lens periphery, thus alleviating the original peripheral defocus in the wearing eye.

[0003] Currently, most mainstream myopia control lenses employ a single-structure defocus microlens or a contrast-reducing design in the peripheral area. However, such single optical intervention methods have limited effectiveness for some myopic children who are not sensitive to intervention. Therefore, there is an urgent need to develop a new type of lens that can simultaneously achieve the dual optical effects of peripheral defocus and contrast suppression, thereby effectively reducing the image quality of the peripheral field of vision and improving the actual effect of myopia control. Summary of the Invention

[0004] In view of this, the present invention provides an eyeglass lens with a hexagonal spherical microstructure on the front surface and a low-contrast design on the rear surface, in order to solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spectacle lens with a hexagonal spherical microstructure on the front surface and a low-contrast design on the rear surface includes: a lens body, wherein the lens body is divided into a central optical region, a hexagonal spherical microstructure distribution region, and a peripheral optical region from its geometric center outwards. The hexagonal spherical microstructure distribution region is disposed on the surface of the lens body. The hexagonal spherical microstructure distribution region includes multiple concentrically arranged annular positive spherical microstructures and annular semi-transparent light scattering region microstructures. The annular positive spherical microstructures are arranged radially in sequence on the front surface of the lens body, and the annular semi-transparent light scattering region microstructures are arranged radially in sequence on the rear surface of the lens body.

[0007] Furthermore, the annular semi-transparent light scattering region microstructure includes a semi-transparent light scattering region microstructure, which are arranged sequentially.

[0008] Furthermore, the annular spherical microstructure includes: multiple spherical microstructures and a transition region, wherein the spherical microstructures and the transition region are arranged alternately.

[0009] Furthermore, the spherical microstructure, the transition region, and the semi-transparent light scattering region microstructure each have a substrate and a microstructure; the spherical microstructure can generate relatively stable refractive power and myopia defocus; the semi-transparent light scattering region microstructure can generate relatively stable refractive power and low contrast.

[0010] Furthermore, the refractive power of the hexagonal spherical microstructure distribution area, the central optical area, and the peripheral optical area is the same.

[0011] Furthermore, the myopic defocus and low contrast provided by the spherical microstructure, the transition region, and the semi-transparent light scattering region microstructure are not entirely the same.

[0012] Furthermore, the spherical microstructure, transition region, and semi-transparent light scattering region microstructures provide the same myopic defocus and low contrast.

[0013] Furthermore, the radial widths of the spherical microstructure, the transition region, and the semi-transparent light scattering region microstructure are the same.

[0014] Furthermore, the central optical region is hexagonal with a circumscribed circle radius of R1; the hexagonal spherical 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 spherical microstructure distribution region.

[0015] The beneficial effects of this invention are as follows:

[0016] The annular spherical microstructures on the front surface of the lens body of this invention are all hexagonal annular bands. The annular spherical microstructures are arranged alternately from the center outwards, and the annular spherical microstructures are arranged alternately with transition zones and spherical microstructures. The hexagonal annular semi-transparent light scattering zone microstructures are arranged alternately from the center outwards on the rear surface of the lens body. Each spherical microstructure can generate relatively stable refractive power and myopia defocus, and each semi-transparent light scattering zone microstructure can generate relatively stable refractive power and low contrast. Defocus and low contrast are alternately introduced in the peripheral retinal field of vision, thereby improving the myopia intervention effect. Attached Figure Description
