Embodiment Construction

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0025] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations...

Abstract

The invention provides a multi-progressive-point zooming lens. The multi-progressive-point zooming lens comprises a transmission type focusing lens; a first structure, a second structure, a third structure and a fourth structure are arranged on the incident light surface of the transmission type focusing lens; the first structure and the second structure are symmetrical with respect to a first center line of the incident light surface; the third structure and the fourth structure are symmetric with respect to a second center line of the incident light surface; the boundary of the third structure is tangent to the boundary of the first structure and the boundary of the second structure; the boundary of the fourth structure is tangent to the boundary of the first structure and the boundary of the second structure; a plurality of first annular structures are internally tangent in sequence to form the first structure, protrude out of the incident light surface and are used for transmittinglight; and a plurality of second annular structures are internally tangent in sequence to form the third structure, protrude out of the incident light surface and are used for transmitting the light.The invention further provides glasses, which comprise the multi-progressive-point zooming lens. The multi-progressive-point zooming glasses have the advantage of continuous zooming, so that the visual fatigue of a user is reduced.

Description

technical field [0001] The invention belongs to the field of lens technology, and more specifically relates to a multi-progressive zoom lens and glasses. Background technique [0002] When a person's eyes are farsighted, the length of the eye axis of the eye is shorter, and the ability to adjust the near point is weak; when a person's eyes are nearsighted, the length of the eye axis of the eye is longer, and the ability to adjust the far point is weaker. weak. Although the traditional multi-progressive zoom glasses can improve the adjustment ability of the eyes to a certain extent, they have the disadvantage that the focal points of the multi-progressive zoom glasses are discontinuous, which causes discomfort to the user. Contents of the invention [0003] One of the objectives of the present invention is to provide a multi-progressive point zoom lens to solve the technical problem that traditional multi-progressive point zoom glasses have discontinuous zooming in the pri...
