Description

Technical Field

[0001] The utility model relates to a lens which utilizes microstructure and point diffusion superposition technology to inhibit the growth of the eye axis, and belongs to the technical field of optical lenses. Background Art

[0002] Axial growth refers to the process of gradual increase in the length of the anterior-posterior axis of the eyeball, which is generally considered to be one of the main causes of myopia. Axial growth causes the focus to be behind the retina rather than directly on the retina, causing distant objects to appear blurry. Some measures can help inhibit the growth of the axial length and slow down the progression of myopia, especially for people who already have myopia. Wearing suitable glasses can correct vision and reduce the adjustment power of the eyes, thereby slowing down the growth of the axial length. An existing lens uses multi-point defocus technology. The principle of multi-point defocus technology is to set multiple focusing points on the lens so that the focus of the myopic person is dispersed in multiple directions and distances. This design of dispersed focus can guide the eyes to switch between different focuses, allowing the eyeball to make natural adjustments and alternating movements between near and far, thereby reducing the elongation of the axial length and the progression of myopia. However, this technology can only create advanced imaging and form myopic defocus, but cannot reduce the contrast, especially for electronic devices with display screens such as televisions, mobile phones, computers, and tablets. Their strong contrast and brightness will stimulate the growth of the axial length, thereby affecting the effect of multi-point defocus on inhibiting axial growth.

[0003] Therefore, it is urgent to propose a new type to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of the research and development of the utility model is to solve the problem that the existing lenses using multi-point defocus technology can only produce advanced imaging and form myopic defocus, but cannot reduce the contrast. A brief overview of the utility model is given below to provide a basic understanding of certain aspects of the utility model. It should be understood that this overview is not an exhaustive overview of the utility model. It is not intended to determine the key or important parts of the utility model, nor is it intended to limit the scope of the utility model.

[0005] The technical solution of this utility model:

[0006] A lens that utilizes microstructure and point diffusion superposition technology to inhibit eye axis growth, comprising a lens body, wherein the lens body comprises a main lens structure, a point diffusion annular structure, a microlens annular structure and a clear vision area, wherein the clear vision area is arranged at the center of the main lens structure, and the point diffusion annular structure and the microlens annular structure are alternately arranged on the main lens structure with the same center to form a dual-effect inhibition area, and the dual-effect inhibition area is arranged outside the clear vision area.

[0007] Preferably: it also includes an outer point diffusion annular zone structure, and the outer side of the dual-effect inhibition zone is provided with an outer point diffusion annular zone structure.

[0008] Preferably: the main lens structure comprises a first optical surface and a second optical surface, the first optical surface is close to the user's eye side, the second optical surface is far from the user's eye side, and the microlens ring structure is arranged on the first optical surface or the second optical surface.

[0009] Preferably, it also includes an inner point diffusion annular zone structure, and the inner point diffusion annular zone structure is arranged between the bright vision area and the dual-effect inhibition area.

[0010] Preferably, the point diffusion annular band structure, the outer point diffusion annular band structure and the inner point diffusion annular band structure are all multiple annular band structures composed of a plurality of light diffusion points arranged in a circular array.

[0011] Preferably, the microlens annular structure is an annular structure in which a plurality of microlenses are arranged in a circular array.

[0012] Preferably, the number of the microlens ring-shaped structures is 4, and one point diffusion ring-shaped structure is arranged between every two adjacent microlens ring-shaped structures.

[0013] Preferably, the defocus of the microlens is from +4.0D to +6.0D, and the defocus of the bright vision area is from +6.00D to +4.00D.

[0014] Preferably, the diameter of the bright vision zone is 5.0 mm-8.0 mm, and the diameter of the dual-effect inhibition zone is in the range of 10.35 mm-60.71 mm.

[0015] The utility model has the following beneficial effects:

[0016] 1. The point diffusion ring belt structure and microlens ring belt structure of the utility model adopt two technologies, point diffusion and multi-point defocusing, which change the contrast and brightness of the image while creating multiple blurred or defocused visual environments. By creating defocused, blurred and bright visual environments, the excessive use of the eyes for close objects is reduced, thereby reducing the risk of myopia;

[0017] 2. The utility model can provide a wider range of visual correction. It can not only correct myopia, but also improve the visual quality at close and long distances, so that the eyes can get a clearer and more comfortable visual experience at all distances;

[0018] 3. The utility model improves the comfort and naturalness of the lens, avoids excessively obvious visual distortion and difficulty in adapting, and allows people to gradually adapt to and enjoy the visual effects of the lens;

[0019] 4. The alternately separated arrangement of the point diffusion ring belt structure and the microlens ring belt structure of the utility model avoids the influence of the light diffusion point on the defocus range of the microlens, that is, avoids the introduction of optical distortion caused by the coincidence of the light diffusion point and the microlens, directly causing visual distortion or other adverse optical effects on the lens, which will have a negative impact on the visual experience, causing the shape, size or position of the image or object to be deformed, and the optical transparency and transmission rate of the microlens may decrease, thereby affecting the visual clarity and color reproduction, and reducing the visual quality of the lens;

[0020] 5. The alternating and separate arrangement of the point diffusion ring-band structure and the microlens ring-band structure of the utility model saves production costs, because directly processing the light diffusion points on the microlens requires more complex manufacturing processes and technical support to ensure the consistency and accuracy of the optical effect, which requires higher production costs and technical requirements, which will limit its application in large-scale manufacturing.
