Description

Technical Field

[0001] The present application relates to the technical field of myopia glasses, and in particular to a kind of spectacle lens. Background Art

[0002] Due to the unique physiological structure of the eyeball, the refraction of the eye is asymmetric in the upper, lower, left and right directions, and the amount of asymmetry of each person's eyeball is different. The existing defocus lenses either do not have regional correction or are not customized according to individual differences. Therefore, they cannot completely produce the correct defocus effect, resulting in the ineffective prevention and control of myopia. Conventional myopia correction lenses are mostly single-vision lenses. When worn, the middle light focuses on the retina, while the peripheral light focuses behind the retina. Studies have shown that the focusing method of this type of single-vision lens will aggravate the development of myopia in myopic people.

[0003] In order to suppress the progression of myopia, some researchers have proposed the accommodation theory and the defocus theory, and designed defocus glasses. This type of lens is provided with a first refractive area for correcting vision, and a second refractive area for suppressing the progression of myopia by focusing light in front of the retina. The second refractive area is formed into a plurality of independent island areas or a continuous Fresnel lens. When in use, while visually distinguishing the image of the object formed by the first refractive power, the development of myopia is suppressed by the image obtained in front of the retina by the second refractive power in addition to the first refractive power.

[0004] In the related art, the image formed in front of the retina is formed by parallel light being refracted through multiple independent island-shaped areas or through a continuous Fresnel lens and focused in front of the retina. However, the size and curvature of each microlens in the independent island-shaped areas or the sawtooth lens of the Fresnel lens are difficult to control, resulting in the failure of light to be refracted according to the established curvature requirements, thereby affecting myopia correction.

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] In order to solve the above technical problems, the present application provides a kind of eyeglass, comprising a first refractive area, having a plurality of first lenses, and the plurality of the first lenses enable the light to form an image on the retina; and a second refractive area, having a plurality of second lenses, and the plurality of the second lenses enable the light to form an image in front of the retina; wherein the first lens and the second lens are both prisms, the first lens is tilted in a direction toward the center of the eyeglass, and the second lens is tilted in a direction away from the center of the eyeglass.

[0044] Among them, it is necessary for those skilled in the art to understand that the eyeglass lens is formed from glass, and the first lens and the second lens are integrally formed. The difference is that the refractive powers of the first lens and the second lens are different to ensure differentiated customization in different areas.

[0045] In order to have a more specific understanding of the technical ideas of the present application, the exemplary embodiments are described below in conjunction with the accompanying drawings:

[0046] like Figure 1-Figure 6 As shown, the present application provides a spectacle lens, comprising a first refractive area 1, having a plurality of first lenses 11, wherein the plurality of first lenses 11 enable light to form an image on the retina; and a second refractive area 2, having a plurality of second lenses, wherein the plurality of second lenses enable light to form an image in front of the retina; wherein both the first lens 11 and the second lens are prisms, the first lens 11 is tilted in a direction toward the center of the spectacle lens, and the second lens is tilted in a direction away from the center of the spectacle lens.

[0047] The eyeglasses provided in the embodiment of the present application have inconsistent inclination directions of the first lens 11 and the second lens, so that the focused light rays are inconsistently deflected. Parallel light rays are refracted outwards through the first lens 11, and are finally imaged on the retina through the combined refraction on the inner surface of the eyeglasses, which is a correction area. Parallel light rays are refracted inwards through the second lens, and are finally imaged in front of the retina through the combined refraction on the inner surface of the eyeglasses, which is a defocus area. Through the above-mentioned arrangement, the light rays are able to change their refraction position and focal position according to the predetermined bending requirements of the first lens 11 and the second lens, ensuring that the light rays are just focused on the retina, and the second refractive area 2 is focused in front of the retina, avoiding hyperopic defocus, thereby effectively inhibiting the tendency of the eyeball to grow backward and playing a role in preventing and controlling myopia.

[0048] In an optional solution of the present application, the sizes of the first lenses 11 in the first refractive area 1 are the same, and the inclination angles of the first lenses 11 are α, 10°<α<60°; the sizes of the second lenses in the second refractive area 2 are the same, and the inclination angles of the second lenses are β, 10°<β<60°.

[0049] In an optional solution of the present application, the size difference of the second lenses in each second refractive region 2 is 100 nm-100 μm. Specifically, the second lenses in each second refractive region 2 have at least three different sizes.

[0050] In an optional solution of the present application, the area of ​​the first lens 11 in the first refractive region 1 is 0.5 mm 2 -3.5mm 2 , the area of ​​the second lens in the second refractive region 2 is 0.5 mm 2 -3.5mm 2 .

[0052] In one embodiment of the present application, the first lens 11 and the second lens protrude from the eyeglass lens, and / or the first lens 11 and the second lens are recessed toward the eyeglass lens. It should be noted that the first lens 11 and the second lens can be convex or recessed relative to the eyeglass lens to control the imaging requirements of different areas.

[0053] In one embodiment of the present application, a plurality of the first lenses 11 and a plurality of the second lenses are distributed in a ring shape on the eyeglass lens, and form a plurality of concentric circles, and the concentric circles are centered at the center of the eyeglass lens. Figure 3As shown, it includes multiple concentric circles formed by multiple annuli, and from the inside to the outside, the diameter of the first concentric circle close to the center is 10.00mm-12.00mm, the inside of the annular zone corresponds to the clear imaging area, and the second refractive area 2 is 20%-60% of the area occupied by the lens. , and is prepared into an individualized wavefront aberration guiding eyeglass lens.

[0054] like Figure 3 As shown, the diopter of each second refractive area 2 is the same and uniform throughout the entire circle.

[0055] Or, if Figure 4 As shown, with respect to the functional division of the eyeglass lens, the second refractive area 2 is divided into: a first functional area for adjusting the internal and external refractive errors of the eyeball, the first functional area comprising an inner functional area 31 and an outer functional area 32, the inner functional area 31 and the outer functional area 32 being two relatively arranged fan-shaped areas with a central angle of 60-90°; and a second functional area for adjusting the distance of vision, the second functional area comprising a distance functional area 41, a near functional area 42 and a middle distance functional area 43, the near functional area 42 surrounds the middle distance functional area 43, the near functional area 42, the distance functional area 41 and the middle distance functional area 43 form two relatively arranged fan-shaped areas with a central angle of 90-120°.

The refractive power of the microlenses in different functional areas is different. When worn, there is no unclear visual area, the discomfort is low, and the wearer can easily adapt.

[0057] Furthermore, the positive addition values ​​of each functional area are as follows: the refractive power of the distance functional area 41 and the middle distance functional area 43 is +2.00D-+3.00D, the refractive power of the near functional area 42 is +2.50D-+3.50D, the refractive power of the medial functional area 31 is +2.50D-+3.50D, and the refractive power of the lateral functional area 32 is +1.50D-+2.50D.

[0058] Please continue to refer to Figure 3 As shown, all the functional areas form an annular surface, wherein the inner functional area 31, the outer functional area 32, the near functional area 42, the far functional area 41 and the middle distance functional area 43 are all fan-shaped rings, and the near functional area 42 is concentrically arranged with the middle distance functional area 43.

[0059] In one embodiment of the present application, the angle between one side of the inner functional area 31 or the outer functional area 32 and the horizontal direction is 10-45°, and the angle between the other side of the inner functional area 31 or the outer functional area 32 and the horizontal direction is 10-30°. That is, the angle between one side of the near functional area 42, the far functional area 41 or the middle distance functional area 43 and the horizontal line is 45-90°, and the angle between the other side of the near functional area 42, the far functional area 41 or the middle distance functional area 43 and the horizontal line is 10-30°.

[0062] In one embodiment of the present application, the first lens 11 and the second lens 21 protrude from the first surface 51, and / or the first lens 11 and the second lens 21 are recessed relative to the first surface 51.
