Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optics, in particular to a pair of eyeglass lenses and eyeglasses. Background Art
[0002] Myopia is an optical disease of the eye in which images of distant objects are focused at the fovea, or in front of the retina. Excessive axial growth often leads to high myopia, which is associated with serious vision-threatening conditions such as cataracts, glaucoma, myopic maculopathy, and retinal detachment.
[0003] In the current myopia control theory, a method of producing peripheral retinal myopic defocus can be used. By controlling the focus of light entering the glasses from the side, a signal for the eye to stop growing is triggered within a field of view of 10-20 degrees. Spherical microlenses are usually used to produce myopic defocus, or laser-processed dot matrix is used to form a low-contrast area of the lens. Axicon mirrors can also be used to simultaneously produce myopic defocus and low-contrast areas. The vertex of the axicon mirror is a non-smooth endpoint, which produces stray light and reduces retinal imaging contrast. Utility Model Content
[0004] The embodiment of the utility model provides a spectacle lens and glasses, wherein the spectacle lens uses polyhedral microlenses distributed on a base lens to generate stray light to reduce the contrast of the peripheral retina, while controlling the focus of light entering the glasses to generate myopic defocus and control the progression of myopia in the user's eyes.

[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0037] Figure 1 This is a schematic diagram of the side view structure of the first eyeglass lens provided by an embodiment of the utility model, Figure 2 The three-dimensional structure diagram of the first polyhedral microlens provided in the embodiment of the utility model is shown in FIG. Figure 1 and Figure 2 The spectacle lens comprises a base lens 10 and a plurality of polyhedral microlenses 20 located on one side surface of the base lens 10. When light passes through the area where the polyhedral microlenses 20 are located and is transmitted to the human eye, the light is focused in front of the retina to form myopic defocus. The polyhedral microlens 20 comprises a bottom surface and at least two side surfaces. The bottom surface coincides with the surface of the base lens 10. The side surfaces are spherical. The side surfaces have a common vertex. The first-order derivative or the second-order derivative of the edge intersecting between two adjacent side surfaces is discontinuous.
[0038] Exemplarily, a microlens is an optical lens with a particularly small diameter, which has the characteristics of small size, light weight and high integration. When ambient light enters the user's eye through the eyeglass lens, the base lens 10 controls the light to focus on the user's retina, so that the user can obtain a clear field of vision; the polyhedron microlens 20 controls the focusing of the light entering the user's eye, so that the light passing through the polyhedron microlens 20 is focused in front of the user's retina, resulting in myopic defocus, controlling the growth of the eye axis, and delaying the progression of myopia. The polyhedron microlens 20 is arranged on one side surface of the base lens 10, and the position and number of the polyhedron microlens 20 can be set according to actual conditions, and the embodiment of the utility model does not impose specific restrictions on this.
[0039] Exemplarily, the polyhedral microlens 20 includes a bottom surface and at least two side surfaces, the bottom surface coincides with the surface of the base lens 10, and the polyhedral microlens 20 can be completely attached to the surface of the base lens 10, and will not affect the base lens 10 to provide a clear field of vision for the user. The side surfaces of the polyhedral microlens 20 have a common vertex, and the first-order derivative or second-order derivative of the edge intersecting between two adjacent side surfaces is discontinuous, and the first-order derivative or second-order derivative is discontinuous, that is, the curve has a turning point with a non-smooth transition. At this time, the vertex of the polyhedral microlens 20 is a non-smooth endpoint. When ambient light is incident on the polyhedral microlens 20, it is refracted to generate stray light, which reduces the retinal imaging contrast and delays the progression of myopia.
[0040] In the field of myopia control, spherical microlenses are usually used. In the field of imaging, due to the discontinuous areas of the first-order derivative and the second-order derivative, large stray light will be caused. Therefore, in the field of imaging optical design, sharp points in optical elements are usually avoided as much as possible, and corners and lens edges are covered as much as possible. The utility model inventor found in the research that after changing the top to a sharp point, more uniform stray light can be generated, which can reduce the retinal imaging contrast and produce a myopia control effect. Therefore, in the field of myopia control, making a vertex on the microlens is different from the conventional design in this field and can produce unexpected benefits. The eyeglass lens provided by the embodiment of the utility model has a plurality of polyhedral microlenses arranged on the surface of one side of the base lens. While the base lens provides a clear field of vision for the user, the polyhedral microlenses control the focusing of the light entering the user so that the light is focused in front of the user's retina, thereby generating myopic defocus, controlling the growth of the eye axis, and slowing down the progression of myopia. The first-order derivative or the second-order derivative of the edge intersecting between two adjacent side surfaces of the polyhedral microlens is discontinuous. When ambient light is incident on the polyhedral microlens, it is refracted to generate stray light, thereby reducing the retinal imaging contrast, delaying the progression of myopia, and improving the myopia control effect.
[0041] Optionally, refer to Figure 2The polyhedral microlens 20 includes two side surfaces, each of which intersects with the bottom surface to form an arc. There is a vertex on the top of the polyhedral microlens 20 (the highest point can be regarded as the vertex when there are two side surfaces), which can produce more uniform stray light and reduce the retinal imaging contrast. At the same time, only two side surfaces are required to achieve the effect of delaying the progression of myopia, reduce costs, and simplify the process.
[0042] Figure 3 The schematic diagram of the three-dimensional structure of the second polyhedral microlens provided in the embodiment of the utility model is shown in FIG. Figure 3 The bottom surface includes n endpoints, and the n endpoints are connected in sequence to form an n-gon, where n is an integer greater than or equal to 3. The line connecting the bottom surface endpoints is an n-gon, that is, the polyhedral microlens 20 has n side faces, and the number of side faces of the polyhedral microlens 20 can be set according to actual conditions to meet different user needs, and the embodiment of the utility model does not impose specific restrictions on this.
[0043] Optionally, the n-gon is a regular n-gon. The radius of the circumscribed circle of the base is R p , then the coordinates of the ith endpoint of the regular n-gon with the base (x i ,y i )for:

[0045]
[0046] Figure 4 A schematic diagram of a three-dimensional structure of a polyhedron formed by connecting the end points of a polyhedron microlens provided in an embodiment of the utility model, referring to Figure 4 , the projection of the common vertex on the regular n-gon is located at the center of the regular n-gon. At this time, the radius of curvature of all sides of the polyhedral microlens is equal, the distance from the vertex to the bottom is h, and the vertex coordinates are (0,0,0). At this time, the coordinates of the i-th endpoint of the regular n-gon on the bottom are:
[0047]
[0048]
[0049] z i =h;
[0050] Figure 4 Take n=3 as an example. At this time, the coordinates of the three endpoints of the side are (x i1 ,y i1 , z i1 ), (x i2 ,y i2 , z i2 ), (x i3 ,y i3 , zi3 ), the radius of curvature is R i , then we can definitely find a sphere with the center at (x i0 ,y i0 , z i0 ), with a radius of R i , then solve the system of equations:
[0051] (x i0 -x i1 ) 2 +(y i0 -y i1 ) 2 +(z i0 -z i1 ) 2 =R i 2 (x i0 -x i2 ) 2 +(y i0 -y i2 ) 2 +(z i0 -z i2 ) 2 ;
[0052] (x i0 -x i1 ) 2 +(y i0 -y i1 ) 2 +(z i0 -z i1 ) 2 =R i 2 (x i0 -x i3 ) 2 +(y i0 -y i3 ) 2 +(z i0 -z i3 ) 2 ;
[0053] (x i0 -x i1 ) 2 +(y i0 -y i1 ) 2 +(z i0 -z i1 ) 2 =R i 2 ;
[0054] Since the coordinates of the three endpoints of the side surface can be obtained according to the coordinates of the bottom endpoint and the vertex coordinates, the coordinates of the center of the sphere can be obtained, and the vector height z corresponding to each point (x, y) on the side surface can be obtained as follows:
[0055]
[0056] As an example, the distance from the vertex to the bottom is h, which is 3 μm, and the radius R of the circumscribed circle of the regular n-gon at the bottom is p The curvature radius R of each side is 0.6 mm. i The circle diameter is 100mm, and the coordinates of the center of one of the side surfaces are (-0.19998850044397265,-0.3463902436984715,99.99920008879452).
[0057] For example, the radius of curvature of the side surface of the polyhedral microlens 20 is R i , the light addition of each surface is A i , the refractive index is n, the surface diopter of the base lens 10 is P, and the added diopter is A i Greater than or equal to -6D, less than or equal to 6D.
[0058] Optionally, the light addition A i Greater than or equal to 2D, less than or equal to 4D.

At this time, the rotational symmetry axes of the multiple polyhedral microlenses 10 intersect at one point, forming a stronger myopic defocus, called high-order defocus, which helps to better control the development of myopia.
[0060] Exemplarily, the number of sides n of the bottom n-gon satisfies n≤32.
[0061] Optionally, the number of sides n of the bottom n-gon satisfies n≤6.
[0062] Exemplarily, a distance h from the common vertex to the bottom surface satisfies that h is greater than or equal to 1 μm and less than or equal to 10 μm.
[0063] Optionally, a distance h between the common vertex and the bottom surface is greater than or equal to 1.5 μm and less than or equal to 5 μm.
[0064] Exemplarily, at least two sides of the n-gon have different lengths, the maximum side length of the n-gon is a, and a is greater than or equal to 0.8 mm and less than or equal to 2.5 mm.
[0065] Optionally, the maximum side length a of the n-gon is greater than or equal to 0.8 mm and less than or equal to 1.5 mm.

Figure 7 The eyeglass lens includes an optical zone 30 located at the center of the lens and a microlens zone 21 surrounding the optical zone 30, and the optical zone 30 does not contain a polyhedral microlens. The optical zone 30 at the center of the lens is set to ensure that the user can see things clearly, and under the premise of ensuring a clear field of vision, the myopia control of the user by the microlens is not affected.
[0067] Figure 8 This is a schematic diagram of the front view structure of the second eyeglass lens provided by an embodiment of the utility model, Fig. 9 This is a schematic diagram of the front view structure of the third eyeglass lens provided by the embodiment of the utility model, Fig.10 This is a schematic diagram of the front view structure of the fourth eyeglass lens provided in the embodiment of the utility model, referring to Figure 1 , Figure 7-Figure 10 , multiple polyhedral microlenses 20 are arranged in multiple layers around the optical zone 30, and each layer of polyhedral microlenses 20 is hexagonal ( Figure 8 ) or concentric ring arrangement ( Fig. 9 ), two adjacent polyhedral microlenses 20 in the concentric rings are tangent to each other, or the polyhedral microlenses 20 are arranged radially like beads, and the diameter of the polyhedral microlenses 20 gradually increases from the center to the outside ( Fig.10 ).
[0068] For example, reference Figure 8 The polyhedral microlenses 20 are arranged in a hexagonal shape around the optical zone 30, the diameter of the polyhedral microlenses 20 is 1.03 mm, the spacing between the polyhedral microlenses 20 is 1.5 mm, and the area of the polyhedral microlenses 20 accounts for 50% of the area of the microlens zone 21. Fig. 9 The polyhedral microlenses 20 are arranged in concentric rings around the optical zone 30. Two adjacent polyhedral microlenses 20 in the concentric rings are tangent to each other. The diameter of the polyhedral microlenses 20 is 1.12 mm. The area of the polyhedral microlenses 20 accounts for 35% of the area of the microlens zone 21. Fig.10The polyhedral microlenses 20 are arranged radially in a beaded pattern around the optical zone 30, and the diameter of the polyhedral microlenses 20 gradually increases from the center to the outside. In other optional implementations, the diameter of the polyhedral microlenses 20 remains unchanged, and the embodiment of the utility model is not limited to this.
