Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042]It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

[0043] In the present invention, the terms "upper", "lower", "left", "right", "front", "rear", "top", "bottom", ...

Abstract

The invention relates to the technical field of lenses and particularly relates to a spectacle lens, a preparation method and glasses. The spectacle lens comprises a prescription lens and at least two layers of micro-lens arrays arranged on the prescription lens, wherein the refractive powers of the at least two layers of micro-lens arrays are different. It can be understood that the refractive power of each layer of micro-lens array is different, the positions of the defocused virtual images generated by each layer are different, and the smaller the refractive power is, the closer the positions of the generated defocused virtual images to the retina is. When the micro-lenses in each layer of micro-lens array generate refractive power changing layer by layer, defocus imaging layers close to the retina or far away from the retina layer by layer can be generated, so eyes can gradually adapt to the defocus imaging layers, problems of visual discomfort, dizziness, eyestrain and the like caused by sudden increase of the defocus degree are avoided, the wearing comfort is better, and the effect of inhibiting or slowing down myopia development is better.

Description

【Technical field】 [0001] The invention relates to the technical field of lenses, in particular to a spectacle lens, a preparation method and glasses. 【Background technique】 [0002] The image of the object seen by the eye with normal vision falls on the retina, the image of the object seen by the myopia falls in front of the retina, and the image of the object seen by the hyperopia falls behind the retina. For myopia and hyperopia, in order to obtain clear vision, people Concave and convex lenses are often used to re-correct the image of an object onto the retina. [0003] The human retina is curved, so the correction of the central area is different from the correction of the peripheral area. For example, when a concave lens is used to correct myopia, the correction of the peripheral area of ​​the concave lens is smaller than that of the central area. However, due to the accuracy of glasses fitting and wearing reasons, the corrected image of objects in the peripheral area ...
