Myopia has become one of the major public health problems affecting the growth and development of children and adolescents in China and the health of the nation. Research has found that although the damage caused by myopia occurs slowly, myopia has long-term effects and hazards on the physical and mental health of children and the whole life, especially for children. Therefore, preventing and controlling myopia at a young age, regular check-ups, early problems and timely intervention are the top priority in the prevention and control of myopia in adolescents.
[0003] In the prior art, various functional lenses for correcting myopia and hyperopia have been developed by industry insiders, and there are numerous related patent applications. However, through careful analysis and extensive experiments, it has been found that the defocus structure and point diffusion structure of the prior art are distributed throughout the lens, completely blocking the entire eye view, even when looking at a distance. The defocus structure and point diffusion structure will be blocked, causing the eyes to adjust when looking at a distance. This transitional adjustment, on the other hand, increases eye strain and causes discomfort. Moreover, the defocus structure of the prior art is a spherical cap island-shaped protruding structure formed on the lens. The central axis of this spherical cap island-shaped protruding structure extends perpendicular to the lens surface towards the front of the lens. Therefore, when the lens is assembled on the glasses for wearing, it is not obvious in inhibiting the growth of the eye axis, and the effect of eye adjustment is not ideal.
[0004] In view of the above, the present inventor, with decades of experience in the eyewear industry, has conducted in-depth research and analysis on the structure of existing corrective functional lenses, improved the structure of existing corrective lenses, and conducted extensive experiments and tests, ultimately designed a new vision correction lens, which gave rise to the present case.

Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.
[0031] It should be noted that the terms up, down, left, right, inner, outer, first, second and the like are only used for description purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the indicated technical features, unless otherwise specifically limited.
[0032] Referring to Figures 1 to 7 The present application discloses a vision correction lens, which has a lens body 1. A center area 2, a defocus area 3 and a point diffusion area 4 are arranged on the lens body 1. Figure 1 The perspective view shows that the defocus area 3 on the front of the lens body 1 and the point diffusion area 4 on the back of the lens body 1 can be seen at the same time.
[0033] The center area 2 includes a front center area and a back center area. The front center area is located at the center position of the front of the lens body 1, and the back center area is located at the center position of the back of the lens body 1. The front center area and the back center area are oppositely arranged.
[0034] The defocus area 3 is located in the lower half of the front surface of the lens body 1, and a plurality of adjustment pyramids 31 are arranged on the defocus area 3. The top of each adjustment pyramid 31 is inclined towards the center C of the lens body 1, so that the top of each adjustment pyramid 31 is directed towards the inside of the lens body 1 and the central intermediate position in any direction, so as to fully exert the adjustment effect on the eye and more effectively inhibit the axial elongation and control the development of the ametropia. As shown in the figure, the adjustment pyramids 31 are arranged in a gradually expanding manner from the center C of the lens body 1 to the periphery, that is, the adjustment pyramids 31 near the center C of the lens body 1 are smaller, and the adjustment pyramids 31 far from the center C of the lens body 1 are gradually larger. Alternatively, the adjustment pyramids 31 are arranged in a ring shape from the center C of the lens body 1 to the periphery, which is not shown in the figure. The number and arrangement density of the adjustment pyramids 31 are not limited by the figure and can be determined according to the design requirements. The upper edge A of the defocus area 3 can be an arc line with a low middle and high ends as shown in the figure, so that the defocus area 3 has a crescent shape, or a straight line, so that the defocus area 3 has a semicircular shape, which is not shown in the figure. Moreover, the upper edge A of the defocus area 3 can pass through the center C of the lens body 1 as shown in the figure, or be above or below the center C of the lens body 1, which is not shown in the figure. The adjustment pyramids 31 are prisms or cones, and the height of the adjustment pyramids 31 is 0.5-1.5 mm, for example, 1 mm, which is equivalent to 300 degrees. The specific height can be adjusted according to the actual needs of the axial elongation inhibition. The specific shape of the upper edge A is not limited by the figure and can be other shapes required by the design. Different shapes of the upper edge A result in different shapes and sizes of the defocus area 3, and the adjustment effect is slightly different, but all belong to the protection scope of the present application.

Figure 3 Figure 6 Figure 7 The point diffusion area 4 can be a micro grating structure or a scattering micro point, so that the light is scattered when passing through the lens. When the light passes through the micro grating structure or the scattering micro point, the light reaching the retina becomes softer, thereby reducing the adjustment pressure of the eye and helping to control the deepening of myopia.
[0036] The lens body 1 has a first dioptric power D for correcting vision except the accommodation cone 31, the accommodation cone 31 has a second dioptric power E different from the first dioptric power D, for adjusting the eye, focusing the image on a position other than the retina of the eye, inhibiting the growth of the eye axis, controlling the development of the refractive error of the eye.
[0037] The utility model discloses still a kind of vision correction glasses, its lens uses the aforementioned a kind of vision correction lens, not to be shown in this paper.
[0038] The utility model discloses because only in the lower half of the front of lens body 1 is set to defocus area 3, lens only in lower half has the effect of adjusting the eye, and in the upper half of the front of lens body 1 does not have the effect of adjusting the eye, when looking at far place, it will not be blocked by accommodation cone 31 and affect sight, also will not be intervened and affected by accommodation cone 31, retain the original effect of original lens, avoid the pressure generated by transition adjustment, so that when looking at far place, it can keep relaxed, no uncomfortable feeling is generated;Meanwhile, point diffusion area 4 on the back of lens body 1 can reduce contrast, so that light becomes more soft, thereby reducing the adjustment pressure of eye, help to control the deepening of myopia.
[0039] The above is only the embodiment of the utility model, and is not the limitation of the protection scope of the utility model. It should be pointed out that the equivalent changes made by the person skilled in the art after reading the present specification, according to the design idea of the case, fall within the protection scope of the case.
