All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model.

In the description of the present utility model, it should be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

The applicant has found that the two most popular microstructural designs on the market today are concentric annulus designs, which are capable of forming a continuous non-distinct signal stimulus in the saccade region, but lacking in layout variation, and triangular honeycomb designs, respectively. The latter can provide more individual intra-pupil placement patterns, but may result in reduced microstructure functional effects due to the lack of continuous signal stimulation. Therefore, there is a need to design a new type of spectacle lens to solve the above technical problems.

Referring to fig. 1, there is provided an ophthalmic lens comprising: a parent mirror 10, the parent mirror 10 comprising an optical center 100; at least one set of first annular zones 20, the first annular zones 20 being disposed on the parent mirror 10 and surrounding the optical center 100, the first annular zones 20 comprising a plurality of sets of first microlenses 201 connected to each other; at least one set of second zones 30, the second zones 30 being disposed on the parent mirror 10 and surrounding the optical center 100; the second endless belt 30 includes a plurality of sets of second microlenses 301 connected to each other; wherein the distance between the geometric center of the first microlens 201 and the optical center 100 is equal; the distance between the geometric center of the second microlens 301 and the optical center 100 is not equal.

Further, the geometric center specifically refers to the most central position of the symmetrical object, and may be, for example, the center of a circle, the center of a sphere, etc.; while the distance between the geometric center and the optical center is understood to be the linear distance between the two points.

In some embodiments, the distances between the geometric centers of the first microlenses 201 and the optical center 100 are equal, which can be understood specifically that the distances between the geometric center of each first microlens 201 on the first annular band 20 and the optical center 100 are equal, so that a certain continuous non-clear vision signal stimulus can be generated, and a myopia defocus stimulus function of a defocus region is ensured to delay myopia deepening.

In some embodiments, the distance between the geometric center of the second microlens 301 and the optical center 100 is not equal. The inequality is understood to mean that the distances between the geometric center and the optical center 100 of at least four second microlenses 301 on the second annulus 30 are unequal, so that the microstructure can keep out of focus or keep the intensity effect of the optical signal different from clear vision at different parts of the saccade, and the continuously changing microstructure can help the eyeball system obtain more non-clear vision signals with tiny variations through different saccade positions, so that the periphery of the retina is always in a slight adjustment adaptation process to the non-clear vision signals to a greater extent, so as to help the stimulus effect not be easily accepted by the eyeball system, thereby forming the function weakening similar to drug resistance.

In some embodiments, the distance between the geometric center of the second microlens 301 and the optical center 100 has a maximum value R _max mm and minimum value R _min mm, satisfy: r is more than or equal to 0.1 _max -R _min And is less than or equal to 10.

Referring to fig. 3 and 4, wherein the microlens of fig. 3 is convex relative to the surface of the parent mirror 10, the surface of the microlens of fig. 4 is concave relative to the surface of the parent mirror 10 such that the incident light rays pass through the microstructure of the annulus, and the focal point of the image is farther from the focal plane of the imaging focal point of the incident light rays passing through the optical zone.

In some embodiments, referring to FIG. 2, the first annular bands 20 are spaced apart along the radial direction of the parent mirror 10; the radial direction of the parent mirror 10 can be understood as the direction in which the optical center 100 of the parent mirror extends towards the edge of the parent mirror.

In some embodiments, referring to FIG. 1, the second ring bands 30 are spaced apart along the radial direction of the parent mirror 10.
