Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0039] See also Figure 1A microstructure lens comprises: a lens body 100, a first microstructure unit 20 and a plurality of second microstructure units 30; the lens body 100 is used to produce clear vision, and the lens body 100 has an optical center 101; the first microstructure unit 20 is used to produce unclear vision, the first microstructure unit 20 is connected to the lens body 100, the first microstructure unit 20 surrounds the optical center 101, and the geometric center of the first microstructure unit 20 coincides with the optical center 101; the plurality of second microstructure units 30 are used to produce unclear vision, the plurality of second microstructure units 30 are connected to the lens body 100, and the plurality of second microstructure units 30 are arranged around the first microstructure unit 20; the geometric center of any one of the plurality of second microstructure units 30 does not coincide with the geometric center of the first microstructure unit 20, and the geometric centers of any two of the plurality of second microstructure units 30 do not coincide.

[0040] It can be understood that the lens body 100 has a clear vision correction function. The lens body 100 is a symmetrical structure, which can be a plane mirror or a spherical thin lens. Therefore, the optical center 101 of the lens body 100 coincides with its geometric center; the first microstructure unit 20 is arranged around the optical center 101, and the geometric center of the first microstructure unit 20 coincides with the optical center 101. Therefore, the first microstructure unit 20 is symmetrical relative to the optical center 101, thereby improving the wearer's adaptability to the non-clear vision signal emitted by the retinal peripheral receiving microstructure without affecting the comfort of wearing the lens at the center of the macula; the geometric center of the second microstructure unit 30 does not coincide with the geometric center of the first microstructure unit 20, which actually means that the geometric center of the second microstructure unit 30 does not coincide with the optical center 101. It shows that the second microstructure unit 30 is not concentric with the lens body 100 and the first microstructure unit 20, and the geometric centers of any second microstructure unit 30 do not coincide, which also shows that the second microstructure units 30 are not concentric with each other. Therefore, the setting of the second microstructure unit 30 can introduce an asymmetric microstructure area on the lens body 100 to form stimulation signal micro-fluctuations. Since the first microstructure unit 20 and the second microstructure unit 30 are both used to produce non-clear vision, the first microstructure unit 20 and the second microstructure unit 30 have the function of not focusing light on the retina. Combined with asymmetry, a certain amount of stimulation micro-fluctuations can be brought about, which can enhance the lasting effect of the lens on the wearer's refractive error intervention, especially the dynamic adaptability during eye rotation is reduced, which can help retain the time of high-intensity stimulation effects.

[0041] It should be further explained that the geometric center defined in this embodiment is the most central position of the shape having symmetry. Therefore, it can be understood that the shapes of the first microstructure unit 20 and the second microstructure unit 30 are symmetrical structures.

[0042] In some embodiments, the lens body 100 includes a first surface close to the eye and a second surface away from the eye in actual application; the first microstructure unit 20 and the second microstructure unit 30 can be arranged on the first surface or the second surface at the same time, or can be arranged on the first surface and the second surface independently, and the specific arrangement method can be based on actual requirements. The surface shape of the first surface and the second surface is selected from at least one of a spherical surface, an aspherical surface, and a free-form surface.

[0043] In some embodiments, clear vision includes that after the wearer wears the glasses, the eye can obtain a clear field of vision through the area. The clear vision model includes no diopter (0 degrees) or a diopter based on correcting the refractive error of the human eye.

[0044] In some embodiments, the non-clear vision includes that after the wearer wears the glasses, when the incident light passes through the first microstructure unit 20 or the plurality of second microstructure units 30, defocusing occurs at the periphery of the retina, thereby producing non-clear image quality on the retina. Alternatively, when the incident light passes through the first microstructure unit 20 or the plurality of second microstructure units 30, the light energy formed by the outgoing light in the eye is higher or lower than the light energy of the lens body 100, so as to reduce or enhance the image sharpness or saturation, so that the contrast between the light passing through the first microstructure unit 20 or the plurality of second microstructure units 30 and the lens body 100 is not equal. Alternatively, when the incident light passes through the first microstructure unit 20 or the plurality of second microstructure units 30, a diffuse spot is generated in front of, on, or behind the retina in the eye, thereby producing non-clear vision; or, when the incident light passes through the first microstructure unit 20 or the plurality of second microstructure units 30, high-order aberrations, such as aberrations of at least 3rd order or more, can be generated, so that the image quality deteriorates, thereby producing non-clear vision.

[0045] In some embodiments, see further Figure 2 , the lines connecting the geometric centers of the adjacent second microstructure units 30 enclose a polygon, the polygon is arranged around the optical center 101, and the number of vertices of the polygon is equal to the number of the second microstructure units 30. It can be understood that when the lines connecting the geometric centers of the adjacent second microstructure units 30 enclose a polygon, the microstructure lens with a slightly eccentric asymmetric layout is similar to the defocus ring offset of the angle molding, which can ensure that the second microstructure unit 30 introduces more complex stimulation signals including high-order aberrations. Compared with the structure of concentric rings, the above setting method can bring better myopia intervention effect.

[0046] In some embodiments, the lines connecting the geometric centers of adjacent second microstructure units 30 form a circle, and the circle is disposed around the optical center 101 .

[0047] In some embodiments, the polygon is a regular polygon, and the center of the second microstructure unit 30 is located at the vertex of the regular polygon, and the geometric center of the first microstructure unit 20 coincides with the geometric center of the regular polygon. The geometric center of the second microstructure unit 30 is equidistant from the optical center 101, and the number of vertices of the regular polygon is equal to the number of the second microstructure units 30. It can be understood that the regular polygon may include a regular triangle, a regular quadrilateral, a regular pentagon, a regular hexagon, etc. The geometric center of the regular polygon can be understood as the center of the inscribed circle or circumscribed circle of the regular polygon. Figure 2 For example, the regular polygon shown in the figure is a regular decagon, wherein the number 1 is the position of the geometric center of the first microstructure unit 20, and the numbers 2 to 11 correspond to the positions of the geometric centers of the ten second microstructure units 30. Figure 2 The arrangement ensures that the second microstructure unit 30 can further enhance the lasting effect of the lens on the wearer's refractive error intervention; at the same time, the vertices of the regular polygon can also facilitate the determination of the position of the second microstructure unit 30 on the lens body 100 to simplify the design of the lens structure.

[0048] In some embodiments, the distance between the vertex of the regular polygon and the optical center 101 is R1 mm, satisfying: 0.1≤R1≤2. Figure 2 , the geometric center of the regular polygon also coincides with the optical center 101, so the distances from each vertex on the regular polygon to the optical center 101 are equal. R1 can be any one of 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm or a range between any two values. When R1 satisfies the above range, it can be ensured that the second microstructure unit 30 is distributed at a relatively appropriate position on the lens body 100, and the regulation effect of the stimulation signal will not be affected due to R1 being too small, nor will the second microstructure unit 30 be unable to correspond to the retina of the human eye due to R1 being too large.

[0049] In some embodiments, see Figure 3, the line connecting the centers of at least two of the plurality of second microstructure units 30 is a spiral line; the line connecting the center of any one of the plurality of second microstructure units 30 and the center of the first microstructure unit 20 is a spiral line. It can be understood that when the line connecting the geometric centers of the first microstructure unit 20 and the second microstructure unit 30 is a spiral line, and the geometric centers between the second microstructure units 30 are spiral lines, the microstructure lens with a micro-eccentric asymmetric layout is similar to the defocus ring offset of the angle molding, which can ensure that the second microstructure unit 30 introduces more complex stimulation signals including high-order aberrations. Compared with the structure of concentric rings, the above setting method can bring better myopia intervention effect.

[0050] In some embodiments, see further Figure 3 , reference numeral 1 is the position of the geometric center of the first microstructure unit 20, and reference numerals 2 to 11 correspond to the positions of the geometric centers of the ten second microstructure units 30, respectively. Figure 3 The arrangement ensures that the second microstructure unit 30 can further enhance the lasting effect of the lens on the wearer's refractive error intervention; at the same time, the spiral line can also facilitate the determination of the position of the second microstructure unit 30 on the lens body 100 to simplify the design of the lens structure.

[0051] In some embodiments, the distance between the centers of adjacent second microstructure units 30 is R2 mm, satisfying: 0<R1≤2; the distance between the center of the first microstructure unit 20 and the center of the second microstructure unit 30 adjacent to the first microstructure unit 20 is R3 mm, satisfying: 0<R3≤2. Wherein, R2 can be any one of 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, or a range between any two values. When R2 satisfies the above range, it can be ensured that the second microstructure units 30 are distributed at relatively appropriate positions on the lens body 100, and the adjustment effect of the stimulation signal will not be affected due to R2 being too small, nor will the second microstructure unit 30 be unable to correspond to the retina of the human eye due to R2 being too large. R3 can be any one of 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, and 2mm, or a range between any two of the values. When R3 satisfies the above range, it can be ensured that the first microstructure unit 20 and the second microstructure unit 30 adjacent thereto are distributed at relatively appropriate positions on the lens body 100.

[0052] In some embodiments, the distance difference between the geometric centers of adjacent second microstructure units 30 is 0.05-3 mm, for example, any value of 0.05 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.8 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, or a range between any two values.

[0053] In some embodiments, see Figure 5 , the first microstructure unit 20 and the second microstructure unit 30 include a plurality of microlenses 40; among the plurality of microlenses 40, at least two microlenses 40 are connected to each other. It can be understood that the first microstructure unit 20 and the second microstructure unit 30 can be an annular structure formed by connecting a plurality of microlenses 40 to each other, or the microlenses 40 may not be continuously connected, so that the first microstructure unit 20 and the second microstructure unit 30 are a non-closed annular structure. A plurality of microlenses 40 means at least two or more, and the microlenses 40 have the function of not focusing light on the retina, and the lens body 100 can use this to intervene in the development of adolescent refractive error.

[0054] In some embodiments, the first microstructure unit 20 and the second microstructure unit 30 are at least one of a circle and a polygon. The first microstructure unit 20 and the second microstructure unit 30 are symmetrical structures, preferably regular polygons.

[0055] In some embodiments, the microlens 40 is at least one of a circular shape, an elliptical shape, and a polygonal shape.

[0056] In some embodiments, the surface shape of the microlens 40 is selected from at least one of a spherical surface, an aspherical surface, a toric surface, a cylindrical surface, and a free-form surface.

[0057] In some embodiments, the diameter of the microlens 40 is 0.1-3 mm. For example, the diameter can be any one of 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2.0 mm, 2.5 mm, and 3.0 mm, or a range between any two values. It is understood that when the diameter of the microlens 40 meets the above range, it can be ensured that when the human eye is looking straight or scanning, the full aperture light beam of the peripheral field of view of the retina can completely cover the lens corresponding to the microlens 40, ensuring that the human eye has more clear visual signal stimulation, making it easier for the wearer to adapt.

[0058] In some embodiments, see further Figure 4 , there is a spacing D1 mm between the first microstructure unit 20 and the second microstructure unit 30 adjacent to the first microstructure unit 20, satisfying: 0≤D1≤3. For example, D1 can be any value of 0mm, 0.1mm, 0.2mm, 0.5mm, 0.8mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, or a range between any two values. When D1 satisfies the above range, it can be ensured that the position between the first microstructure unit 20 and the second microstructure unit 30 is within a reasonable range, which can further improve the wearer's adaptability.

[0059] In some embodiments, see further Figure 5 , the spacing D1 has a maximum value D max and minimum value D min This is because the diameters of the microlenses 40 in the first microstructure unit 20 and the second microstructure unit 30 are not equal. At this time, the first microstructure unit 20 and the second microstructure unit 30 composed of microlenses 40 of different diameters connected end to end also have the function of forming a non-clear stimulation signal, and the maximum value D max Satisfy less than or equal to 3mm, minimum value D min Satisfy greater than or equal to 0mm.

[0060] In some embodiments, see further Figure 4 , there is a spacing D2 mm between adjacent second microstructure units 30, satisfying: 0≤D2≤5. For example, D2 can be any value of 0mm, 0.1mm, 0.2mm, 0.5mm, 0.8mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, or a range between any two values. When D2 satisfies the above range, it can ensure that the position between the second microstructure units 30 is within a reasonable range, and further expand the fluctuation of the stimulation signal generated by the asymmetric structure, helping to improve the duration of the stimulation effect.

[0061] In some embodiments, see further Figure 4 , there is a distance D3 mm between the first microstructure unit 20 and the optical center 101, which satisfies: 2≤D3≤5. For example, D3 can be any value of 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, or a range between any two values. It should be noted that the size of D3 determines the range of the clear vision area on the lens body 100. When the range of D3 is met, it can be ensured that the pupil scanning range can cover the clear vision area during the wearing process of the human eye, so as to ensure that the clear vision signal and the unclear stimulation signal play a role in intervening myopia.

[0062] In some embodiments, the microstructured lens can be cast or injection molded by a metal mold, or cast by a glass mold to form a desired prescription diopter or semi-finished product, and the semi-finished product is then processed by a workshop to obtain the desired prescription diopter. In some embodiments, the microstructured lens can also be made into the desired prescription diopter or semi-finished product by a metal or glass mold using a UV light curing process, and the semi-finished product is then processed by a workshop to produce the spectacle lens required by the wearer, or the spectacle lens or spectacle lens blank produced by a bonding process.

[0063] In some embodiments, the material of the microstructure lens includes polymer materials or inorganic non-metallic materials. Among them, the polymer material includes thermoplastic resin or thermosetting resin, and the inorganic non-metallic material includes glass, etc. Thermoplastic resin includes polycarbonate or polymethyl methacrylate; thermosetting resin includes any one of acrylic resin, episulfide resin, thiourethane resin, allyl resin and polyurethane.

[0064] In some embodiments, a coating film is formed on the surface of at least one side of the microstructure lens, and the coating film includes a transparent coating film that increases the transmittance of the lens, a hard coating film that increases the durability of the lens, a reflective film that blocks harmful light, an anti-reflection and anti-reflection film that realizes imaging visibility, a polarizing film with a color-changing function, or other color-changing films doped with ultraviolet-sensitive materials, etc. The coating film itself can have different colors, and the visual color under the reflection condition can be green, blue, yellow, purple, etc., or other colors.

[0065] In some embodiments, the microstructure lens is directly prepared by a mold, and the mold may include an upper mold base and a lower mold base. The working surface of the upper mold base is a concave surface, which is used to shape the first surface and the second surface respectively.

[0066] In some embodiments, the microstructured lens obtained by the above process can be combined with a glasses frame to further obtain glasses, and the shape of the microstructured lens can be circular, square, elliptical or other special-shaped structures. It should be noted that the shape of the microstructured lens can be roughly the above shape and is not limited to a perfect geometric shape.

[0067] In some embodiments, see Figure 6 and Figure 7 , the first microstructure unit 20 and the second microstructure unit 30 can also be a micro-column 50, and the micro-column 50 is an integral structure, so that the first microstructure unit 20 can be arranged around the optical center 101, and the second microstructure unit 30 is arranged around the first microstructure unit 20; the cylindrical power of the micro-column 50 is 5.00D, the micro-column 50 is circular or cylindrical, and the line connecting the geometric centers of the first microstructure unit 20 and the second microstructure unit 30 is Figure 7 The number of the second microstructure units 30 is 5, and Figure 7 The numbers corresponding to the geometric centers of the second microstructure units 30 are 2 to 6. Figure 6 and Figure 7 The setting makes the first microstructure unit 20 and the second microstructure unit 30 on the lens body 100 have the function of not focusing the light on the retina. At the same time, the geometric center of the first microstructure unit 20 and the geometric centers of the multiple second microstructure units 30 do not coincide. The eccentric asymmetric layout can introduce micro-fluctuations of the stimulation signal in the microstructure area on the lens surface, ensuring that the dynamic adaptability during eye movement is reduced, which can help retain the time of high-intensity stimulation effects and improve the durability of the lens in intervening in the development of refractive errors.

The description of the above embodiments is only used to help understand the technical solutions and core ideas of the present application; ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
