[0002] Since high myopia not only leads to decreased vision, but also has the risk of causing a variety of eye complications, such as retinal detachment (which can cause serious visual impairment or even blindness), myopia control has become one of the hot topics in related industries. Many years ago, the eyewear industry and related companies began to produce and sell myopia control products. Among them, in recent years, new myopia defocus frame glasses lenses with micro-convex lens design have been launched in the domestic market, providing a new product for myopia control.

[0003] Existing new lenses use a microstructure design with multiple micro-convex lenses, but there are differences in the effects of lenses with different microstructure designs, which is related to the lens design details, often related to the arrangement and combination of the micro-convex lenses in the microstructure, the size of the area occupied, etc. To this end, this patent provides a lens with optimized microstructure.

[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] like Figure 1-2 As shown, the preferred structure of a lens for delaying myopia progression described in the present invention.

[0028] like Figure 1 As shown, the lens for delaying myopia progression has a central area 10, a microstructure area 20 and a planoscopic area 30. The central area forms a regular area with the optical center of the lens as the center, and the central area has a refractive power for correcting myopia; the outer contour of the central area is a regular hexagon, and the diameter of the inscribed circle of the regular hexagon is 9 mm. The microstructure area is arranged around the central area, and the microstructure area is formed by a plurality of uniformly distributed micro convex lenses.

[0029] It should be noted that the plano area is all areas on the surface of the lens except the central area and the microstructure area.

[0030] In the microstructure optimization design of the utility model, the micro-convex lenses in the microstructure area of ​​the lens will focus the light in front of the retina, so that a clear image cannot be formed. In order to ensure the wearer's clarity when looking far away, there is no micro-convex lens in the regular hexagonal area in the center of the lens. The diameter of the inscribed circle of the hexagonal area is about 9mm. When the line of sight passes through this area, it can ensure that the wearer can see clearly in the distance. After the light in the central area passes through, it can be focused into a clear image on the wearer's retina, thereby correcting the refractive error.

[0031] It should be noted that a large number of micro-convex lenses are evenly distributed, and the intervals between the micro-convex lenses are the same.

[0032] In a preferred embodiment, the outer contour of the microstructure area is a circular circle, and the central area is formed in the middle of the microstructure area; wherein the microstructure area is a circular area with a diameter of 33 mm and an optical center of the lens as the center.

[0033] In a preferred embodiment, the microstructure area has no less than 400 micro convex lenses. Specifically, the refractive form of the micro convex lenses is a spherical lens, and the refractive power of the micro convex lenses can be between +1.00D and +7.50D.

[0034] The patented micro-convex lens is different from the traditional single-focus lens, which makes this lens product have a unique function: the light passing through a single convex lens will be focused in front of the wearer's retina, forming myopic defocus. The light passing through multiple convex lenses will not focus on the same point, so it cannot form a clear image in front of the retina (such as Figure 2 ), the eyes will not relax their accommodation when looking at near objects like wearing bifocals or progressive lenses.

[0035] like Figure 3 As shown, the utility model provides a pair of glasses, comprising a frame and a lens detachably connected to the frame, wherein the lens is the above-mentioned lens.

[0036] When choosing a frame, it is usually recommended to choose a style with better wearing stability. If necessary, you can also choose an ear hook to assist wearing. If the frame is deformed after wearing for a period of time, it is necessary to adjust it in time to ensure that the wearing position meets the fitting requirements.

[0037] For other structures of the lenses and glasses for delaying the progression of myopia described in this embodiment, refer to the prior art.

[0038] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
