Description

Technical Field

[0001] The present invention relates to the technical field, and specifically refers to a composite microstructure lens for myopia prevention and retardation. Background Art

[0002] A composite microstructure lens is a new type of spectacle lens. By adding tiny structures to the lens, the propagation path of light is changed, thereby achieving functions such as improving eyesight and retarding the development of myopia.

[0003] However, in the prior art, the filling rate of the composite microstructure lens cannot be perfectly balanced with the visual subjective feeling and the prevention and control effect. When the filling rate is high, the visual subjective feeling is not good, and it is not easy to adapt to wearing in the initial stage, but the prevention and control effect is good; when the filling rate is low, the visual quality will be improved, but the prevention and control effect will decline. With the static and single prevention and control design, the brain will produce neural adaptation during long-term wearing and use, so that the prevention and control effect will become weaker and weaker as the wearing time increases. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a composite microstructure lens for myopia prevention and retardation in view of the deficiencies mentioned in the above background art.

[0005] To solve the above technical problem, the technical solution provided by the present invention is: a composite microstructure lens for myopia prevention and retardation, which includes a lens body. A functional area is provided inside the lens body. The functional area includes a central optical correction area provided on the inner side. The lens body is provided with an annular light diffusion area outside the central optical correction area. A composite nested microstructure functional area is provided outside the annular light diffusion area. An annular blank area is provided outside the composite nested microstructure functional area. The central optical correction area, the annular light diffusion area and the composite nested microstructure functional area are set up to form a functional area.

[0006] Further, the total diameter of the lens of the lens body is set to be 60 mm to 80 mm, the diameter of the functional area is set to be 40 mm to 60 mm, the diameter of the central optical correction area is set to be 3 mm to 5 mm, and the photometric range is set to be +2.00D to -12.00D.

[0007] Further, the annular light diffusion area is set to have a width of 1.5 mm to 2.5 mm outside the central optical correction area. The annular light diffusion area is provided with a diameter of 0.01 mm to 0.2 mm. The annular blank area is set to have a width of 5 mm to 15 mm outside the composite nested microstructure functional area

[0008] Further, the composite nested microstructure functional region is arranged in the region 4 mm or more away from the center. The composite nested microstructure functional region is filled with a plurality of circular nested microstructures with a diameter of 0.5 mm to 1 mm, arranged in a staggered and layered manner. The microstructure includes an internal microlens region with an internal diameter of 0.05 mm to 0.3 mm and an external filling of 36 or more light diffusion units with a diameter of 0.01 - 0.2 mm. The photometric range of the internal microlens is set to +12.00D to -12.00D.

[0009] Further, the photometric range of the internal microlens is set to -0.25D to -10.00D, and the numerical value of the composite nested microstructure functional region changes sequentially by +0.12D from the inner layer to the outer layer.

[0010] Further, the photometric range of the internal microlens is set to +0.25D to +10.00D, and the numerical value of the composite nested microstructure functional region changes sequentially by -0.12D from the inner layer to the outer layer.

[0011] Further, the photometric range of the internal microlens is set to +10.00D to -10.00D, and the positive and negative single rings of the microlens are arranged alternately.

[0012] Further, the photometric range of the internal microlens is set to +10.00D to -10.00D, and the positive and negative multi - rings of the microlens are arranged alternately.

[0013] After adopting the above structure, the present invention has the following advantages: In this application, the structure is changed from dots or microlenses to a nested concentric - circle composite structure, with a microlens inside and light diffusion outside. When in use, as the eyes rotate, the incident light on the eyes will change dynamically and irregularly among the three states of defocus, convergence, and divergence. This can not only reduce the generation of negative defocus signals but also reduce the neural adaptation of the brain's visual system to regular prevention and control designs. With long - term use, the delaying effect is not easily weakened. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Combined with the attached Figure 1-2 , a composite microstructure lens for myopia prevention and delay, which includes a lens body 1. A functional area is provided inside the lens body 1. The functional area includes a central optical correction area 2 provided on the inner side. The lens body 1 is provided with an annular light diffusion area 3 outside the central optical correction area 2. A composite nested microstructure functional area 4 is provided outside the annular light diffusion area 3. An annular blank area 5 is provided outside the composite nested microstructure functional area 4. The central optical correction area 2, the annular light diffusion area 3 and the composite nested microstructure functional area 4 are set up to form a functional area.

[0019] The total diameter of the lens body 1 of the lens is set to be 60mm - 80mm. The diameter of the functional area is set to be 40mm - 60mm. The diameter of the central optical correction area 2 is set to be 3mm - 5mm. The photometric range is set to be +2.00D - -12.00D. The annular light diffusion area 3 is set to have a width of 1.5mm - 2.5mm outside the central optical correction area 2. The diameter inside the annular light diffusion area 3 is set to be 0.01mm - 0.2mm. The annular blank area 5 is set to have a width of 5mm - 15mm outside the composite nested microstructure functional area 4. The composite nested microstructure functional area 4 is set in the area 4mm outside from the center outwards. The composite nested microstructure functional area 4 is provided with a plurality of circular nested microstructures with a diameter of 0.5mm - 1mm filled and arranged in an interlaced and layered manner. The microstructure includes an internal microlens area with an internal diameter of 0.05mm - 0.3mm and an external filling of 36 or more light diffusion units with a diameter of 0.01 - 0.2mm. The photometric range of the internal microlens is set to be +12.00D - -12.00D.

[0020] Example 1, Microlens negative defocus, better wearing effect for exophoria population

[0021] The photometric range of the internal microlens is set to be -0.25D - -10.00D. The values of the composite nested microstructure functional area 4 change sequentially by +0.12D per circle from the inner layer to the outer layer. For example, the photometric of the microlens in the innermost first circle is -6.00D, the second circle is -5.88D, and so on, changing by 0.12D per circle, and the photometric changes sequentially from the inside outwards to strengthen the prevention and control effect of the central area. It is also possible to unify and fix the defocus amount, such as setting the photometric of all microlenses to be -8.00D.

[0022] Example 2, Microlens positive defocus, better wearing effect for esophoria population

[0023] The brightness range of the internal microlens is +0.25D to +10.00D, and the composite nested microstructure functional area 4 is set to change from the inner layer to the outer layer with a value of -0.12D per circle. For example, the brightness of the first circle of microlenses in the innermost circle is +6.00D, and the second circle is +5.82D, and so on. The brightness changes by 0.12D per circle, and changes from the inside to the outside to enhance the prevention and control effect of the central area. The defocus amount can also be unified and fixed, such as all microlenses The brightness is set to +7.00D.

[0024] Example 3: Alternating positive and negative single rings of microlenses to enhance dynamic prevention and control effects

[0025] The internal microlens has a brightness range of +10.00D to -10.00D, and the positive and negative single rings of microlenses are arranged alternately. For example, the brightness of the first innermost circle of microlenses is +6.00D, the second circle is -6.00D, the third circle is +6.00D, and so on, arranged alternately.

[0026] Example 4: Alternating positive and negative microlenses to enhance dynamic prevention and control effects

[0027] The internal microlens has a brightness range of +10.00D to -10.00D, and the positive and negative microlenses are arranged alternately. For example, the brightness of the 1st to 2nd ring microlenses in the innermost circle is +6.00D, the brightness of the 3rd to 4th ring microlenses is -6.00D, the brightness of the 5th to 6th ring microlenses is +6.00D, and so on.

[0028] Similarly, you can also set it negative first and then positive. The brightness of the 1st to 2nd ring microlenses in the innermost circle is -6.00D, the brightness of the 3rd to 4th ring microlenses is +6.00D, the brightness of the 5th to 6th ring microlenses is -6.00D, and so on.

[0029] Three or more rings may also be arranged alternately.

[0030] A 3-5mm optical correction zone is set in the center, which is customized according to the optometry prescription to correct refractive errors and ensure clear and stable central vision. A 1.5mm-2.5mm wide annular light diffusion zone is set outside the optical correction zone as a control buffer zone to reduce the contrast intensity of retinal signals around the fovea. A composite nested microstructure functional area is set 4mm outside. The light diffusion and microlens are nested in concentric circle structures and arranged in an alternating manner to form a negative defocus signal interference zone. Accompanied by eye movement, the light passing through this area changes dynamically and irregularly in the three states of defocusing, converging and diverging, thereby reducing the intensity of negative defocus signals reaching the retina as much as possible, avoiding the brain from recognizing negative defocus signals that promote the development of myopia, thereby delaying the occurrence time and development speed of myopia.

[0031] The above describes the present invention and its implementation manners. Such description is not restrictive, and the actual structure is not limited thereto. In summary, if those of ordinary skill in the art are inspired thereby and without departing from the gist of the present invention-creation, structures and embodiments similar to the technical solution are designed without creative efforts, they shall fall within the protection scope of the present invention.
