Abstract
Description
Technical Field
[0001] This utility model belongs to the field of optical lens technology, specifically relating to a myopia control lens that can achieve vision fogging. Background Technology
[0002] In recent years, with the increased use of electronic products and the increased time spent on close-range visual tasks, eye strain has risen rapidly, making myopia particularly common among teenagers. Currently, many teenagers wear multi-point defocus lenses to control myopia progression. However, existing multi-point defocus lenses have a random arrangement of micro-dots, resulting in uneven distribution or inconsistent coverage of defocus microlenses or blurred dots per unit area. Given the intricate structure of the human eye, even minute optical deviations can lead to significant differences in performance, especially for children whose vision is still developing. Long-term use of defocus lenses may result in a relative decrease in their effectiveness. Utility Model Content
[0003] The purpose of this invention is to provide a myopia control lens that can achieve visual fogging, solving the problem that existing multi-point defocus glasses lenses have uneven distribution or inconsistent coverage per unit area, resulting in a relatively reduced effect when wearing defocus glasses.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A myopia control lens capable of achieving visual fogging includes a first refractive portion and a second refractive portion. The second refractive portion is located around the periphery of the first refractive portion. The second refractive portion is provided with a plurality of microlenses arranged in accordance with the Fibonacci sequence and the Fermat spiral.
[0006] Furthermore, the distance between any two of the microlenses is equal.
[0007] Furthermore, all of the microlenses are circular.
[0008] Furthermore, the first refractive portion of the lens is the central refractive correction visible area of the lens.
[0009] Furthermore, the second refractive portion of the lens is a fogging functional area.
[0010] Furthermore, the first refractive portion of the lens is circular, and the second refractive portion of the lens is annular.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] The myopia control lens with vision fogging provided in this utility model has a number of microlenses arranged in the second refractive part according to the Fibonacci sequence and the Fermat spiral. These microlenses, with equal spacing between any two, form a fogging functional area, controlling myopia development and preventing its aggravation. Furthermore, the arrangement of the microlenses according to the Fibonacci sequence and the Fermat spiral has excellent natural aesthetic characteristics, ensuring uniform coverage within a unit area. This uniform fogging function avoids any minor optical deviations, facilitating better control of myopia development. This avoids the significant differences in use that minor optical deviations might cause, ensuring that children in their visual development stage do not experience a relative decrease in the effectiveness of defocused glasses during long-term use.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-4This invention provides a myopia control lens capable of achieving visual fogging, comprising a first refractive portion 10 and a second refractive portion 20. The first refractive portion 10 is the central refractive correction visible area of the lens, and the second refractive portion 20 is located around the periphery of the first refractive portion 10. The second refractive portion 20 is provided with a plurality of microlenses 21 arranged according to the Fibonacci sequence and conforming to the Fermat spiral, forming a fogging functional area. This arrangement of the microlenses 21 according to the Fibonacci sequence and conforming to the Fermat spiral maximizes the number of microlenses 21 within a limited space. This arrangement ensures sufficient space for each microlens 21, preventing overlap. The spacing between any two microlenses 21 is equal. Furthermore, the arrangement of several microlenses 21 according to the Fibonacci sequence and Fermat's spiral possesses excellent natural aesthetic characteristics, enabling uniform coverage of the microlens 21 within a unit area. This ensures uniform atomization function, avoiding any minor optical deviations and facilitating better control of myopia development. It also prevents significant differences in usage that might result from minor optical deviations, ensuring that children in their visual development stage do not experience a relative decrease in the effectiveness of defocused glasses during long-term use.
[0020] It should be noted that in this embodiment, the arrangement of several microlenses 21 according to the Fibonacci sequence and the Fermat spiral follows the formula r²=a²θ, that is, the radius increase within a unit angle is proportional to the square root of the angle, which can achieve a constant area density.
[0021] Furthermore, the spacing between any two microlenses 21 is equal, which makes the atomization function uniform and consistent, avoiding any slight optical deviations, facilitating better control of myopia development, and thus avoiding the possibility of significant differences in use caused by slight optical deviations.
[0022] Furthermore, all of the microlenses 21 are circular.
[0023] Furthermore, the first refractive portion 10 of the lens is the central refractive correction visible area of the lens.
[0024] Furthermore, the second refractive portion 20 of the lens is a fogging functional area. That is, the second refractive portion 20 of the lens achieves a fogging functional area for visual acuity through a plurality of microlenses 21 arranged in accordance with the Fibonacci sequence and the Fermat spiral. Thus, in addition to visual acuity correction, the first refractive portion 10 of the lens, through the fogging functional area formed by the plurality of microlenses 21 arranged in accordance with the Fibonacci sequence and the Fermat spiral in the second refractive portion 20, can control the development of myopia and prevent its worsening.
[0025] Furthermore, the first refractive portion 10 of the lens is circular, and the second refractive portion 20 of the lens is annular.
