Description

Technical Field

[0001] This utility model belongs to the field of optical lens technology, specifically relating to a fogging myopia control lens that reduces the contrast sensitivity of some visual cells. Background Technology

[0002] Myopia control lenses are eyeglasses used to correct myopia. They work by altering the way light enters the eye, allowing the eye to focus on a clear image, thus correcting myopia. Myopia control lenses can be divided into three types: monofocal, bifocal, and multifocal. Normally, when the eye is relaxed, parallel light entering the eye focuses precisely on the retina, forming a clear image—this is called emmetropia (normal vision). However, myopia is the opposite; the image cannot be clearly focused on the retina, making it difficult to see distant objects and causing rapid elongation of the eye axis. Currently available multifocal lenses use specific optical signals in the peripheral area of ​​the eye to regulate the eye's growth trend. However, with increasing screen time and frequent use of mobile phones and computers, visual cells overuse oxygen, leading to worsening myopia or the development of astigmatism. Furthermore, a certain level of tolerance may develop over time.

[0003] Therefore, it is necessary to provide a fogging myopia control lens that reduces the contrast sensitivity of some visual cells, so as to slow down the development of myopia through this fogging technology that reduces the contrast sensitivity of some visual cells. Utility Model Content

[0004] The purpose of this invention is to provide a fogging myopia control lens that reduces the contrast sensitivity of some visual cells, thus solving the problem of tolerance issues that arise in existing multi-point defocus lenses, which use light to form specific optical signals in the peripheral area of ​​the eye to regulate the growth trend of the eyeball.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fogging myopia control lens that reduces the contrast sensitivity of some visual cells includes a first lens unit and a second lens unit that are composited. The first lens unit and the second lens unit are respectively provided with a central light-transmitting area at their center. The central light-transmitting area is provided with a defocusing area around its periphery. The defocusing area is provided with a plurality of micro laser dots arranged in accordance with the Fibonacci sequence and the Fermat spiral.

[0007] Furthermore, the spacing between any two of the aforementioned micro-laser points is equal.

[0008] Furthermore, the central light-transmitting area is circular.

[0009] Furthermore, the defocused area is annular.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention provides a fogging myopia control lens that reduces the contrast sensitivity of some visual cells. It comprises a first lens unit and a second lens unit, both composite. Each lens unit has a central light-transmitting area at its center, and a defocusing area surrounding each central light-transmitting area. Each defocusing area has a plurality of micro-laser points arranged according to the Fibonacci sequence and a Fermat spiral. These micro-laser points, arranged according to the Fibonacci sequence and a Fermat spiral, are spaced equally apart, forming a fogging structure. The central light-transmitting area, in addition to vision correction, is further enhanced by the presence of micro-laser points arranged according to the Fibonacci sequence and a Fermat spiral in the defocusing area. The atomized structure formed by micro-laser dots arranged in a Fermat spiral can reduce the contrast sensitivity of some visual cells, preventing excessive oxygen consumption by visual cells, thereby controlling myopia development and preventing myopia from worsening. In addition, the arrangement of several micro-laser dots according to the Fibonacci sequence and the Fermat spiral has excellent natural aesthetic characteristics, enabling uniform coverage of the micro-laser dots within a unit area, resulting in a uniform atomized structure that facilitates better control of myopia development. This effectively solves the problem of tolerance issues that arise after a certain period of time in existing multi-point defocus lenses, which use light to form specific optical signals in the peripheral area of ​​the eye to regulate the growth trend of the eyeball.

[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 1-5 This invention provides a fogging myopia control lens that reduces the contrast sensitivity of some visual cells. It includes a first lens unit 10 and a second lens unit 20, which are composite components. Each of the first and second lens units has a central light-transmitting region 30 at its center. A defocusing region 40 is located around the periphery of each central light-transmitting region 30. Each defocusing region 40 has a plurality of micro-laser points 41 arranged according to the Fibonacci sequence and a Fermat spiral. This arrangement of micro-laser points 41 forms a fogging structure. This arrangement maximizes the number of micro-laser points 41 within a limited space, and ensures that each micro-laser point 41 has sufficient space, avoiding... The overlapping of the micro-laser points 41, with equal spacing between any two micro-laser points 41, allows the central light-transmitting area 30, based on vision correction, to reduce the contrast sensitivity of some visual cells through the atomized structure formed by the micro-laser points 41 arranged according to the Fibonacci sequence and the Fermat spiral in the defocus area 40. This prevents excessive oxygen consumption by visual cells, thereby controlling myopia development, preventing myopia aggravation, and avoiding the development of tolerance issues. In addition, the arrangement of the micro-laser points 41 according to the Fibonacci sequence and the Fermat spiral has excellent natural aesthetic characteristics, ensuring uniform coverage of the micro-laser points 41 within a unit area. This uniform atomization structure facilitates better control of myopia development and avoids the development of tolerance issues.

[0020] It should be noted that in this embodiment, the several micro laser points 41 are arranged according to the Fibonacci sequence and the Fermat spiral, following 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 of the micro-laser points 41 is equal, so that the coverage area of ​​the micro-laser points 41 can be uniform within a unit area, and the atomization structure is uniform, which makes it easier to control the development of myopia and avoid the corresponding tolerance problem.

[0022] Furthermore, the central light-transmitting area 30 is circular.

[0023] Furthermore, the defocused region 40 is annular.

Around the central light-transmitting area, a defocusing area is formed. Each defocusing area contains a plurality of micro-laser dots arranged according to the Fibonacci sequence and a Fermat spiral. These micro-laser dots, arranged according to the Fibonacci sequence and a Fermat spiral, are spaced equally apart, forming a fogging structure. This reduces the contrast sensitivity of some visual cells, preventing excessive oxygen consumption and thus controlling myopia development and preventing its worsening. The central light-transmitting area... Based on vision correction, this technology utilizes a fogging structure formed by several micro-laser points arranged according to the Fibonacci sequence and Fermat's spiral in the defocus area to control myopia progression and avoid tolerance issues. Furthermore, the arrangement of these micro-laser points according to the Fibonacci sequence and Fermat's spiral possesses excellent natural aesthetic characteristics, ensuring uniform coverage of the micro-laser points within a unit area. This uniform fogging structure facilitates better control of myopia progression and effectively solves the problem of tolerance issues that arise after a certain period, which is a consequence of existing multi-point defocus lenses that use light to form specific optical signals in the peripheral region of the eye to regulate eye growth.
