Background

In recent years, as the burden of students in middle and primary schools increases in class, the popularization of products with electronic screens (hereinafter referred to as electronic products) such as mobile phones and computers, the factors of excessive eye use, insanitary eye use, lack of physical exercise and outdoor activities and the like, the myopia rate of children and teenagers in China is high and continuously rises, and the myopia is gradually reduced in age and serious, so that the problems become a big problem in the future of related countries and nations. In order to practically strengthen the myopia prevention and control work of children and teenagers in the new era, the education department and eight departments such as the national health committee and the like establish a comprehensive myopia prevention and control implementation scheme for children and teenagers, and the implementation of the scheme provides a guideline for the myopia prevention and control of various teenagers.

At present, the treatment research and exploration of the myopia are still in progress, and the research on the mechanism of the myopia occurrence and development, such as the regulation theory, the defocusing theory and other research results, provides a new idea for the treatment and prevention of the myopia. At present, myopia correction methods mainly comprise OK glasses, frame glasses and the like, but the OK glasses have serious foreign body sensation when being worn, and eyes are dry after being worn for a long time. The frame glasses mostly adopt a single-light concave mirror lens and a double-light concave mirror lens, which can correct the vision of a wearer, but easily causes the deepening of the degree.

The latest out-of-focus theory is researched, and the multi-region forward optical out-of-focus lens, the progressive multi-focus lens and the peripheral out-of-focus lens which appear according to the research result are clinically proved to have a good effect of inhibiting the myopic degree from being deepened, can effectively relieve the degree increasing speed of teenagers, and become lenses with a myopic correction effect which can be better than the effect of a shoulder OK lens. Clinical experiments of the multi-region forward optical out-of-focus lens part show that the lens has a good effect of inhibiting the development of myopia, but human eyes see objects through different regions of the glasses when looking far and looking near, and the objects can have certain influence on the visual line and are blurred when looking near through the out-of-focus region.

Meanwhile, when the glasses are used for glasses fitting, special customization needs to be carried out aiming at individuals, and compared with general lenses, the glasses fitting period of the glasses is long, the glasses fitting cost is high, and the glasses are not convenient to popularize and use.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 1 and 2, the present invention provides a functional clip 1 for suppressing the progression of ametropia, including a middle region 111 with high light transmittance and an out-of-focus region 112 surrounding the middle region, wherein microlenses 1121 are uniformly arranged on the out-of-focus region 112, and the diameter of the microlenses 1121 gradually increases from the inner circle to the outer circle of the out-of-focus region 112. The refractive powers of the microlenses of different sizes are different; the intermediate region has the same refractive power as the original, and a certain amount of change occurs due to the refractive power of the microlenses when external light is incident from the defocus region.

Examples

Referring to fig. 1, the utility model provides a functional clip 1 with the function of inhibiting myopia of human eyes, which is used with myopia glasses; referring to fig. 3, a lens holder 10 is provided in fig. 3, the functional type lens 1 is connected to two sides of the lens holder 10, the lens holder 10 may be of a clip-on structure, the functional type lens 1 may be clipped on the frame of the glasses for myopia 2 by the lens holder 10, so that the left and right functional type lens 1 cover the lenses of the glasses for myopia 2, respectively.

It should be noted that the glasses clip shown in fig. 3 is not the only structure, and the functional type clip 1 and the glasses clip can be clamped on the frame of the glasses for myopia 2 in a single-piece clip structure, and the combination modes such as directly clamping the functional type clip 1 on the glasses or integrally connecting the functional type clip 1 and the frame of the glasses for myopia 2 are not limited. Can all be in with the fixed mode of functional

type clamping piece

1 and 2 lens collocation of glasses for myopia the utility model discloses within the scope protection. The functional type clamping piece 1 can be designed into a plane or an arc surface, and the radian of the functional type clamping piece is close to that of a common spectacle lens in the arc surface type, so that the functional type clamping piece can be better matched with the spectacle lens.

Specifically, the method comprises the following steps:

the functional clip 1 comprises a high light transmittance intermediate area 111, the intermediate area 111 is coincident with the optical center of the lens of the myopic glasses 2, and the refractive power of the intermediate area 111 is zero. When external light enters from the middle area 111 of the functional clip, the convergence and divergence of the emergent light of the functional clip 1 are not changed, namely, the myopia glasses 2 installed with the functional clip 1 still have the same refractive correction capability as the original glasses in the area.
