Description

Technical Field

[0001] The utility model belongs to the technical field of lenses, and in particular relates to a multi-point diffusion micro-transmission defocused optical lens. Background Art

[0002] The eyeballs of adolescents are in the growth and development stage, with strong adjustment ability and susceptible to interference from multiple factors. The occurrence and development of myopia is gradual, superimposed and irreversible. Once it is formed, the opportunity for prevention and control will be lost. Therefore, the research on the prevention and control methods of adolescent myopia has very important medical and social significance.

[0003] When a myopic person looks at an object, the central and peripheral images of the object are projected in front of the retina. Using a myopic single-vision corrective lens, the central image can be projected on the retina, and the peripheral image moves backward with the central image and falls behind the retina. The peripheral retina will send out a stimulation signal that the vision is defective, notifying the eyeball to stretch, causing the retina to grow backwards and stimulating the growth of the eye axis, thereby causing myopia to increase every year. In order to control the increase in myopia, a multi-point diffusion micro-transmittance defocus optical lens is provided. Utility Model Content

[0004] In view of this, the technical problem to be solved by the utility model is to provide a multi-point diffusion micro-transmittance defocused optical lens, which solves the problem of increased myopia caused by wearing ordinary myopia lenses in the prior art.

[0005] In order to solve the above technical problems, the utility model discloses a multi-point diffusion micro-transparent defocus optical lens, comprising: a substrate; a clear vision area is provided at the center of the front surface of the substrate, a defocus area is provided at the edge of the clear vision area, the defocus area has a divergent transition area and a uniform viewing area, the divergent transition area surrounds the edge of the clear vision area, and the diameter of the microlens in the divergent transition area is smaller than the diameter of the microlens in the uniform viewing area.

[0006] Furthermore, the edge of the above-mentioned defocusing area is in a polygonal shape.

[0007] Furthermore, the divergent transition zone has a plurality of microlens groups in an annular array, and each microlens group has the same number of microlenses.

[0008] Furthermore, the micro lenses in the divergent transition zone are linearly arranged and distributed along the direction of divergent lines formed by diverging from the center of the clear vision area to the periphery.

[0009] Furthermore, the micro lenses in the uniform viewing area are in a rectangular array, covering other areas except the divergent transition area.

[0010] Furthermore, the diameter of the microlens in the divergent transition zone is half of the diameter of the microlens in the uniform viewing zone.

[0011] Compared with the prior art, the present application can obtain the following technical effects:

[0012] The utility model arranges a divergent transition zone at the edge of the clear vision zone, and the microlenses in the divergent transition zone are in a multi-circle divergent shape, and the diameter of the microlenses is smaller than the diameter of the microlenses in other areas, so that the number of microlenses in the divergent transition zone can be increased, the microlenses close to the edge of the clear vision zone are dense, and the spacing between the microlenses gradually increases outwards until the fixed spacing between the microlenses in the uniform vision zone, so that the image transition observed by the human eye can be well reduced, the abruptness can be reduced, and the fatigue of the eyes can be relieved, so as to better achieve the effect of inhibiting the increase of myopia.

[0013] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The edge of the defocus zone 3 is polygonal in shape; the divergent transition zone 4 has a multi-circle annular array of microlens groups, and the number of microlenses in each circle of microlens groups is the same; the microlenses of the divergent transition zone 4 are linearly arranged and distributed along the divergent line direction formed by diverging from the center of the clear vision zone 2 to the periphery; the microlenses of the uniform viewing zone 5 are in a rectangular array, covering other areas except the divergent transition zone 4; the diameter of the microlenses of the divergent transition zone 4 is half of the diameter of the microlenses of the uniform viewing zone 5.
