Description

[0001] Cross-reference to related applications

[0002] This application is based on and claims priority to Chinese Patent Application No. 202410975675.1, filed on July 19, 2024, entitled “An Ophthalmic Lens”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of lens technology, specifically to an ophthalmic lens. Background Technology

[0004] With the proliferation of electronic products and increased screen time, the vision problems of Chinese teenagers cannot be ignored. The myopia rate among junior high, high school, and university students has exceeded 70%, making myopia prevention and control an urgent priority. The current simple and effective method is to wear corrective glasses, i.e., myopia glasses, which focus light onto the retina. However, for teenagers, whose eyes are still developing, wearing myopia glasses causes the peripheral optical focus of the lens to fall behind the retina, leading to axial elongation and actually exacerbating vision loss.

[0005] Currently, existing spherical and aspherical lenses for myopia do not have the function of preventing the vision of teenagers from deteriorating. Summary of the Invention

[0041] It should be noted that the embodiments in the present disclosure and the technical features in the embodiments can be combined with each other without conflict, and the detailed description in the specific embodiments should be understood as an explanation and description of the purpose of the present disclosure, and should not be regarded as an improper limitation of the present disclosure.

[0042] At present, the technology for slowing down myopia deepening of eye health is mainly the film front defocus technology, which arranges a plurality of microlenses on the lens to form a defocus type number on the peripheral retina to achieve the prevention and control effect. Such lenses have relatively complex process steps, and a small part of the population cannot adapt to the lenses. Studies have shown that reducing the light signal of the peripheral retina can achieve control of axial growth and prevent and control the deterioration of vision.

[0043] Based on this, the following technical solutions are proposed for embodiments of this disclosure:

[0044] This disclosure provides an ophthalmic lens, including:

[0045] The lens body includes at least a central region and a scattering region surrounding the central region, and the scattering region includes at least a first region and a second region.

[0046] Multiple scattering structures are located in the scattering region, and the multiple scattering structures are located in at least the first region and the second region;

[0047] The first pattern information formed by the scattering structure in at least a portion of the first region is the same as the second pattern information formed by the scattering structure in at least a portion of the second region.

[0048] In this embodiment, the ophthalmic lens is divided into a central area and a scattering area surrounding the central area. The central area provides refractive power for vision correction, while the scattering area surrounding the central area contains multiple scattering structures. After passing through these structures, light can effectively reduce the contrast of light around the retina, thereby helping to reduce abnormal changes in the axial length caused by high light contrast, such as elongation or shortening of the axial length. This helps prevent the wearer's myopia or hyperopia from worsening. Furthermore, in the ophthalmic lens provided in this embodiment, the pattern information formed by the scattering structures in different areas has common elements, meaning the scattering structures are regularly arranged. This allows the wearer to experience good comfort while controlling vision deterioration when wearing the ophthalmic lens provided in this embodiment.

[0049] To make the above-mentioned objects, features, and advantages of this disclosure more apparent and understandable, the specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. In describing the embodiments of this disclosure in detail, for ease of explanation, the schematic diagrams may be partially enlarged without adhering to general proportions, and the schematic diagrams are merely examples and should not limit the scope of protection of this disclosure.

[0051] The ophthalmic lens provided by an embodiment of the present disclosure will be described in further detail below with reference to the accompanying drawings.

[0052] As shown in Figure 1 , Figure 2 , the ophthalmic lens comprises a lens body 10, the lens body 10 at least comprising a central region C and a scattering region D arranged around the central region C, the scattering region D at least comprising a first region D1 and a second region D2.

[0053] A plurality of scattering structures 11 located in the scattering region D, the plurality of scattering structures 11 at least located in the first region D1 and the second region D2.

[0054] The first pattern P1 information constituted by the scattering structures 11 in at least part of the first region D1 is the same as the second pattern P2 information constituted by the scattering structures 11 in at least part of the second region D2.

[0055] The lens provided by an embodiment of the present disclosure can be used as a lens for inhibiting the development of myopia or hyperopia.

[0056] In some embodiments, the ophthalmic lens can be a spectacle lens or a contact lens (e.g., a soft contact lens), and the ophthalmic lens can comprise a spherical lens or an aspherical lens. The material of the lens comprises a resin material or an optical glass material.

[0057] Here, the central region C can be understood as a region of the lens for correcting vision, and the refractive power of the central region C is the refractive power of the prescription adopted by the lens for correcting vision.

[0058] In some embodiments, the shape of the central region C can include but is not limited to a circle Figure 1 , an ellipse, a regular hexagon, a conchiform shape Figure 2 , etc.

[0059] In some embodiments, the scattering region D may be located in a region of the lens other than the central region C. However, it is not limited to this. In other embodiments, the lens may also include an edge region (not shown in the figure), with the scattering region D located between the central region C and the edge region (not shown in the figure).

[0060] In some embodiments, when the lens includes an edge region (not shown), the edge region (not shown) may include any desired pattern structure, or the edge region (not shown) may not include a pattern structure. The specific details can be determined according to actual needs and are not specifically limited here.

[0061] Figure 3 A schematic diagram of the structure 11 contained in a myopia lens, arranged in different positions; Figure 4 The diagram illustrates the arrangement of the scattering structure 11 in a farsighted lens at different locations. It should be noted that the methods provided in this disclosure can also be used on any type of lens requiring a scattering structure, and are not listed here. The relevant information regarding the scattering structure 11 included in the above-described lens can be set with reference to the content of any embodiment of this disclosure. Figure 5 The diagram mainly shows a structural schematic of a single scattering structure 11 in different embodiments.

[0062] It should be noted that, in Figure 5 In order to clearly show the specific structure of the scattering structure, many details such as lens type, curvature information, and placement are omitted.

[0063] In some embodiments, such as Figure 3 and Figure 4 As shown, the scattering structure 11 can be disposed on the front surface of the lens (see reference for details). Figure 3 Figure (1) in the middle and Figure 4 (1) Figure in the middle), the back surface, and the bonding surface of the two lens materials (please refer to Figure 1 for details). Figure 3 Figures (2) and (3) in the middle Figure 4 (Figures (2) and (3) in the text).

[0064] In some embodiments, such as Figure 3 and Figure 4 As shown, in some embodiments, the scattering structure 11 includes at least one of a recess or a light-shielding material (see reference for details). Figure 3 , Figure 4 , Figure 5 Figures (1), (2), and (3) in the text and Figure 5 (Figures (4), (5) and (6) in the text).

[0065] In some embodiments, when the scattering structure 11 is located at the interface between the two lens materials, the recessed direction of the scattering structure can be towards the material with a higher refractive index, for example:

[0066] In some embodiments, such as Figure 3 Figure (2) in the middle and Figure 4 As shown in Figure (2), the lens body 10 includes a first lens material 101 and a second lens material 102. When the refractive index of the first lens material 101 is greater than the refractive index of the second lens material 102, the concave direction of the scattering structure 11 is toward the first lens material 101.

[0067] In some embodiments, such as Figure 3 Figure (3) in the middle and Figure 4 As shown in Figure (3), the lens body 10 includes a first lens material 101 and a second lens material 102. When the refractive index of the first lens material 101 is less than the refractive index of the second lens material 102, the concave direction of the scattering structure 11 is toward the second lens material 102.

[0068] In some embodiments, the scattering structure 11 can be made into a recessed structure by means of a laser.

[0069] In some embodiments, such as Figure 3 and Figure 4 As shown, when the scattering structure 11 is a concave structure, the ratio between the maximum value D of the scattering structure 11 in the direction parallel to the thickness of the lens body 10 and the average value W of the shape of the part where the scattering structure 11 intersects with the lens body is between 0.05 and 0.6 (including the endpoint values), for example: 0.1, 0.15, 0.2, 0.25, 0.30, 0.35, 0.4, 0.45, 0.5, 0.55, etc.

[0070] When the size of the recessed structure is within the range mentioned above, the orthographic projection of the obtained scattering structure 11 in the direction parallel to the thickness of the lens body 10 can fall within a large range of the shape formed by the intersection of the scattering structure 11 and the lens body 10. This reduces the number of times light is scattered in the scattering structure 11, which is beneficial to obtaining a stable light scattering effect and a contrast reduction effect, and can effectively reduce the vision decline of the lens wearer.

[0071] In some embodiments, the light-blocking material can be formed on the surface of the lens body 10 by material growth.

[0072] In some embodiments, the scattering structure 11 can also be obtained by a mask etching process after it has been designed.

[0073] In some embodiments, the light-shielding material may include, but is not limited to, a chromium layer.

[0074] Here, the light-shielding material reduces the contrast of light located around the retina by reducing the transmittance of incident light, thereby effectively slowing down the decrease in vision of the lens wearer.

[0075] It can be understood that when the scattering structure 11 is a light-shielding material, the original front surface and rear surface structures of the lens itself are not destroyed, which helps to maintain the stability and good optical performance of the lens when the wearer uses it, and the contrast of light located around the retina can be significantly reduced, reducing the light signal of the peripheral retina to control the axial growth or shortening, achieving the effect of preventing and controlling myopia or hyperopia deepening.

[0076] In some embodiments, as shown in Figure 6 Regardless of whether the scattering structure 11 is a concave structure or a light-shielding material, the cross-sectional shape of the scattering structure can include at least one of a circle, an ellipse, a triangle, a quadrilateral, a regular hexagon, a polygon, and an irregular shape, or a combination thereof.

[0077] In some embodiments, as shown in Figure 13 The shape of the scattering structure 11 includes a regular hexagon, and the boundaries of adjacent scattering structures 11 are connected to each other to form a honeycomb structure in at least part of the scattering area D.

[0078] It can be understood that in this embodiment, since the scattering structure 11 is a bionic structure of a regular hexagon, it helps to include a bionic structure similar to the compound eye structure of insects in the ophthalmic lens, which helps to achieve diffuse reflection to reduce strong light and glare, and helps the lens wearer to inhibit the development of myopia or hyperopia.

[0079] On this basis, further, when the boundaries between the scattering structures 11 are connected to each other to form a honeycomb structure, the arrangement density of the scattering structures 11 on the ophthalmic lens is increased, and the honeycomb network structure also has high reflectivity, so that it can reflect unnecessary polarized stray light and strong light, achieving the effect of light optimization. In this way, the introduction of the bionic structure makes the final ophthalmic lens have multiple beneficial functions, which helps the lens wearer to inhibit the development of myopia or hyperopia from multiple aspects.

[0080] It can be understood that in the embodiment in which the scattering structure 11 includes a regular hexagon, in addition to the case in which the boundaries between the scattering structures 11 each being a regular hexagon are connected to each other to form a honeycomb structure, other possible variations or combinations can be applied to the embodiments of the present disclosure, for example:

[0081] In some embodiments, as shown in Figure 14As shown in (1) to (5) in FIG. 1, the scattering structure 11 includes a first combined pattern A1, which includes a regular hexagon, and at least one of the following shapes or a combination thereof in the middle region of the regular hexagon:

[0082] a circle, an ellipse, a triangle, a quadrilateral, a regular hexagon, a polygon, and an irregular shape.

[0083] In some embodiments, when the scattering structure 11 includes the first combined pattern A1, the first combined pattern A1 can be obtained by the following method:

[0084] First, a regular hexagon pattern is obtained on the lens body 10, which can be obtained by forming a recess or a light-shielding material;

[0085] Then, the pattern structure, such as at least one of the following shapes or a combination thereof, is formed on the middle region of the regular hexagon pattern by adding material or removing material.

[0086] It can be understood that, in some embodiments, when the regular hexagon is formed by the recess method, the material of the lens body 10 can be removed to obtain the regular hexagon pattern, and then the first combined pattern A1 can be obtained by forming a light-shielding material layer on the middle region inside the regular hexagon.

[0087] However, the above is not limiting, and in some other embodiments, when the regular hexagon is formed by the recess method, the material of the lens body 10 can be removed to obtain the regular hexagon pattern, and then the pattern structure in the middle region of the regular hexagon pattern can be obtained by further removing the material of the lens body 10 in the middle region inside the regular hexagon. In actual operation, the method can be flexibly selected according to actual conditions, which is not limited herein.

[0088] It should be noted that when the first combined pattern A1 is obtained by the recess method, the boundary of the pattern structure in the middle region inside the regular hexagon in the vertical projection on the surface of the lens body 10 cannot exceed the boundary of the regular hexagon, so as to effectively prevent the influence on the integrity of the surrounding first combined pattern A1 and further prevent the light between adjacent first combined patterns A1 from being scattered in disorder.

[0089] In other embodiments, the hexagonal pattern can also be obtained by first depositing the light-shielding material and then removing the light-shielding material located on the boundaries of the hexagonal pattern, while the pattern structures located in the middle region of the hexagonal pattern can be obtained by removing the light-shielding material on the boundaries of the pattern structures. Alternatively, the pattern structures can be obtained by first removing the light-shielding material formed in advance and then re-forming the light-shielding material.

[0090] Thus, in the embodiments containing the first combined pattern A1, the structures with different scattering effects can be obtained in the same first combined pattern A1, which is beneficial for forming a bionic structure similar to the compound eye structure of insects, so as to help achieve the function of diffuse reflection to reduce strong light and glare, while further helping the lens wearer to inhibit the development of myopia or hyperopia, according to the actual situation of the lens wearer, such as myopia or hyperopia degree, the situation that the local area of the eyeball needs to be adjusted locally due to some possible reasons, etc.

[0091] In some embodiments, the pattern structures located in the middle region of the hexagonal pattern, such as at least one or a combination of the following shapes of at least one or a combination of circular, elliptical, triangular, quadrilateral, hexagonal, polygonal and irregular shapes, can be spaced apart from each other (for details, please refer to FIG. 1 and FIG. 2 in the description of the first embodiment), but are not limited thereto, and can also exist in a connected manner with each other (for details, please refer to FIG. 3, FIG. 4 and FIG. 5 in the description of the first embodiment). Figure 14 Figure 14

[0092] When the pattern structures exist in a connected manner with each other, the first sub-pattern A11 and the second sub-pattern A12 in the first combined pattern A1 can be further combined to form a new combined structure, and the boundary shape of the new combined structure can also be a hexagonal structure with the same number of sides as the hexagonal shape. That is, in the scheme provided in the embodiments of the present disclosure, in addition to the bionic structure of the hexagonal shape itself, the bionic structure is further contained inside the bionic structure. Not only can the pattern structures located in the hexagonal shape provide varying scattering effects and reduce the contrast change of the light entering the eye, but at the same time, the outline of the bionic structure is as much as possible to be maintained or approached, which helps to exert a better vision regulation effect on myopic patients or hyperopic patients.

[0093] In some embodiments, as shown in FIG. 6, the first combined pattern A1 can be obtained by first forming a hexagonal structure A1a, and then forming a plurality of pattern structures A1b in the middle region of the hexagonal structure A1a. Figure 14 ​​As shown in (6) of FIG. 1, the scattering structure 11 includes a second combined pattern A2, a boundary of an edge of the second combined pattern A2 includes a boundary L1 of a regular hexagon, and inside the second combined pattern A2 includes a plurality of straight line boundaries L2 connected to each other and at least one curved line boundary L3 connected to the straight line boundaries L2.

[0094] It can be understood that, in this embodiment, the second combined pattern A2 includes the boundary L1 of the regular hexagon, which helps to keep the shape of the bionic structure, and the way that the second combined pattern A2 contains both the straight line boundaries L2 and the curved line boundaries L3 helps to form the pattern structure with adjustable scattering effect inside, and the presence of the curved line boundaries L3 helps to show more uniform scattering characteristics in light scattering, the scattering intensity and angle distribution are relatively stable, which helps to further play a better vision control effect on myopic patients or hyperopic patients.

[0095] In some embodiments, the curved line boundary L3 can include an arc line or any other arbitrary curve.

[0096] In some embodiments, the number of curved line boundaries L3 can be greater than the number of straight line boundaries L2, but is not limited thereto, and the number of curved line boundaries L3 can also be less than or equal to the number of straight line boundaries L2.

[0097] In actual operation, the specific number of straight line boundaries L2 and curved line boundaries L3 can be flexibly selected according to actual conditions and is not specifically limited here.

[0098] In some embodiments, the shape of the part of the scattering structure intersecting with the lens body has an average size in the range of 0.1 mm to 1 mm (including the end point value), such as 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm, 1 mm, etc.

[0099] Continuing to refer to Figure 5 It can be seen that, in some embodiments, the scattering structure 11 at least includes a first sub-layer L1 and a second sub-layer L2, wherein the second sub-layer L2 is located above the first sub-layer L1.

[0100] In some embodiments, the combination of the first sub-layer L1 and the second sub-layer L2 can include two or more of the following: the material of the lens body itself, a material from outside with a preset structure (e.g., a film layer), a material with scattering effect inside the lens body, a light blocking material, a material deposited from outside, other optical materials, or a material that can be easily shaped by photocatalysis or thermal catalysis, etc.

[0101] For example, in some embodiments, the first sub-layer L1 can be the material of the lens body 10, and the second sub-layer L2 can be a light blocking material; or, the first sub-layer L1 can be the material of the lens body 10, and the second sub-layer L2 can be a material deposited from outside with a refractive index less than that of the material of the lens body; or, the first sub-layer L1 can be the material of the lens body 10, and the second sub-layer L2 can be one of a light blocking material, a material deposited from outside, other optical materials, or a material that can be easily shaped by photocatalysis or thermal catalysis; or, the first sub-layer L1 can be one or more of a material deposited from outside, other optical materials, or a material that can be easily shaped by photocatalysis or thermal catalysis, and the second sub-layer L2 can be a light blocking material; or, the first sub-layer L1 can be a light blocking material, and the second sub-layer L2 can be one or more of a material deposited from outside, other optical materials, or a material that can be easily shaped by photocatalysis or thermal catalysis.

[0102] Continuing to refer to Figure 5 In some embodiments, the second sub-layer L2 includes a void structure H that does not expose the first sub-layer L1 (see Figs. 2 and 5 of Figure 5 for details);

[0103] Alternatively,

[0104] the void structure H exposes the first sub-layer L1 (see Figs. 3 and 6 of Figure 5 for details).

[0105] It can be understood that when the second sub-layer L2 includes a void structure H but the void structure H does not expose the first sub-layer L1, the material in the surface layer for scattering light is still the second sub-layer L2, which can have the same refractive index, but at the same time, due to the addition of the void structure H, the number of scattering structures 11 is increased, so that multiple scattering structures can be obtained on one scattering structure 11 of the present disclosure, and the effect of simultaneously scattering light by multiple scattering structures is achieved, thereby having a higher scattering effect to help achieve a better contrast reduction effect.

[0106] When the second sub-layer L2 contains the void structure H but the void structure H exposes the first sub-layer L1, the material for scattering light rays on the surface layer can be of two refractive indices, and compared with the case where the surface for scattering light rays contains only one refractive index material, the scattering structure 11 provided by the embodiment can have multiple forms of scattering effect on the incident light rays, which helps to select the required material of the two sub-layers or the specific position of the exposed first sub-layer according to the required scattering effect, such as the need to strengthen, weaken, or change regularly or irregularly, so as to obtain the required scattering effect of the lens.

[0107] In addition to the above structure, in some embodiments, in the same area or different areas, the void structure H in the second sub-layer L2 can also contain the case where the void structure H does not expose the first sub-layer L1 and the case where the void structure H exposes the first sub-layer L1. Compared with the above two embodiments containing the void structure H, the embodiment can have higher flexibility and more possible scattering effects.

[0108] In actual operation, the number, position, size, depth, roughness, etc. of the void structure H can be selected according to actual conditions, which are not limited here.

[0109] In some embodiments, in the embodiment where the void structure H does not expose the first sub-layer L1, the ratio of the thickness of the second sub-layer L2 located below the void structure H and retained to the thickness of the second sub-layer L2 without the void structure H can be in the range of 0.01 to 0.6 (including the end point value), for example: 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, etc.

[0110] In some embodiments, as shown in Figure 8 The scattering area D also includes a connecting structure 12 which connects at least part of the scattering structures 11.

[0111] In some embodiments, the connecting structure 12 is located at least one of the surface or the inside of the lens body.

[0112] In some embodiments, the shape and material of the connecting structure can be the same as or different from the scattering structure. In some embodiments, the connecting structure can also have the same structure and material setting as the scattering structure, and even can have part or all of the same multi-layer structure setting as the scattering structure.

[0113] As shown in Figure 9 In some embodiments, the cross-sectional shape of the connecting structure 12 can include at least one of a circle, an ellipse, a triangle, a quadrilateral, a regular hexagon, a polygon, and an irregular shape, or a combination thereof.

[0114] In some embodiments, the areas between the scattering structures 11 provided with the connecting structures 12 can be located on the entire scattering area D, but are not limited thereto, and in other embodiments, the areas between the scattering structures 11 provided with the connecting structures 12 can also be located on part of the scattering area D.

[0115] In some embodiments, the connecting structures 12 can have the function of reducing the contrast of the incident light at different positions of the lens, but are not limited thereto, and can also not have the above function or have other functions.

[0116] It can be understood that when the connecting structures 12 are contained between the scattering structures 11 in the scattering area D and have the function of reducing the contrast of the incident light at different positions of the lens, the number and density of the scattering structures 11 for reducing the contrast of the incident light at different areas of the lens are effectively increased, which can effectively delay the deterioration of the wearer's vision.

[0117] For the convenience of description, the plurality of scattering structures 11 arranged around the central area C and located on the same surrounding track can be referred to as a group of scattering structures, for example, the first group of scattering structures R1, the second group of scattering structures R2 and the third group of scattering structures R3 in Figure 8 .

[0118] In some embodiments, the connecting structures 12 can be located between two adjacent scattering structures 11 in the same group of scattering structures 11 (for details, please refer to (1) in Figure 8 .

[0119] But not limited thereto, in other embodiments, the connection relationship between the two adjacent scattering structures 11 in (1) in Figure 8 may also be extended to the case that the connecting structures are provided between two scattering structures 11 in adjacent positions between two adjacent groups of scattering structures. For example:

[0120] In some embodiments, as shown in (2) in Figure 8 , the connecting structures 12 connect two scattering structures 11 in adjacent positions between two groups of scattering structures to each other.

[0121] In addition to the above manner, in order to take into account that the densities of the scattering structures 11 and the connecting structures 12 cannot be too large to reduce the conspicuousness of the structures in the scattering area D, the arrangement relationship between the scattering structures 11 and the connecting structures 12 can also be processed as follows:

[0122] In some embodiments, as shown in (3) in Figure 8As shown in FIG. 3 of the drawings, the plurality of connecting structures 12 connect two scattering structures 11 in adjacent positions between two groups of scattering structures, wherein the scattering structures connected by the connecting structures 12 are arranged at intervals in the same group of scattering structures; the plurality of connecting structures 12 connecting adjacent two groups of scattering structures are defined as the same group of connecting structures, and at least in some areas, no connecting structure 12 is arranged in the adjustment area A between two groups of connecting structures 12.

[0123] In this way, in the case of arranging the connecting structures 12 to enhance the scattering effect in some areas, the structure density in the scattering area can be considered not to increase too much at the same time, which helps to reduce the light contrast around the retina and improve the wearing aesthetics.

[0124] In other embodiments, as shown in FIG. 4 of the drawings, Figure 8 As shown in FIG. 4 of the drawings, Figure 8 Compared with FIG. 3 of the drawings, Figure 8 The difference between FIG. 4 of the drawings and FIG. 3 of the drawings is that, at least in some areas, the scattering structures 11 originally located in the second group of scattering structures R2 and the third group of scattering structures R3 and not connected by the connecting structures 12 are transferred to the position where the adjustment area A is located (for example, the first sub-structure 111 in the scattering structure 11 connected by the connecting structure is still located in the original position, and the second sub-structure 112 in the scattering structure 11 is located in the adjustment area A), to further balance the relationship between the strengthening of the scattering effect and the density not increasing too much.

[0125] In yet other embodiments, as shown in FIG. 5 of the drawings, Figure 8 As shown in FIG. 5 of the drawings, Figure 8 Compared with FIG. 4 of the drawings, Figure 8 The difference between FIG. 5 of the drawings and FIG. 4 of the drawings is that, at least in some areas, the scattering structures 11 originally located in the first group of scattering structures R1, the second group of scattering structures R2, the third group of scattering structures R3 and the fourth group of scattering structures R4 and not connected by the connecting structures 12 are all transferred to the position where the adjustment area A is located, to further balance the relationship between the strengthening of the scattering effect and the density not increasing too much.

[0126] In the embodiments of the present disclosure, regarding the distribution and division of the first area and the second area, various cases can be included, and the various cases of the first area and the second area provided by the embodiments of the present disclosure will be further described in detail in combination with the drawings as follows:

[0127] In the embodiments of the present disclosure, the first pattern P1 information and the second pattern P2 information can be understood as follows: the plurality of scattering structures 11 located in at least part of the first region D1 constitute the first pattern P1, the information contained in the first pattern P1 constitutes the first pattern P1 information, the plurality of scattering structures 11 located in at least part of the second region D2 constitute the second pattern P2, and the information contained in the second pattern P2 constitutes the second pattern P2 information.

[0128] Meanwhile, in the embodiments of the present disclosure, the first pattern P1 information and the second pattern P2 information are the same, which includes the case that the first pattern P1 and the second pattern P2 are the same, and the case that the information contained in the first pattern P1 and the second pattern P2 is also the same.

[0129] In addition, if there is other pattern information in the embodiments, it can be understood in the above-mentioned manner.

[0130] In the embodiments of the present disclosure, the scattering region can only include the first region and the second region, but is not limited thereto, and can also include any other possible region, including but not limited to a third region, or a fourth region, a fifth region, or other regions, etc., which can be flexibly selected according to actual needs and is not limited herein.

[0131] Continuing to refer to Figure 1 It can be seen that, in some embodiments, the line O1 passing through the center region C divides the entire lens body 10 into two regions: the first region D1 and the second region D2, and the first pattern P1 information composed of the scattering structures 11 in the first sub-region D11 in the first region D1 is the same as the second pattern P2 information composed of the scattering structures 11 in the second sub-region D12 in the second region D1.

[0132] In some embodiments, the first pattern P1 information and the second pattern P2 information include material composition, size, depth, roughness, spacing, arrangement information, and optical information, etc.

[0133] In some embodiments, the material of the lens includes but is not limited to resin material or optical glass material, etc.

[0134] It can be understood that the greater the depth, the stronger the scattering effect on light; the greater the roughness, the stronger the scattering effect on light, but too large roughness can easily cause chaotic scattering of light, which can reduce the wearing comfort. Smaller spacing can produce better scattering effect, but can also easily cause the scattering structure to have high visibility, which can affect the wearing aesthetics; the arrangement information can include the result obtained after the scattering structure is arranged, which can include multiple information, including but not limited to size, spacing, shape, etc. The optical information can include refractive index, transmittance, single-point scattering, and comprehensive scattering effect, etc.

[0135] Therefore, in actual operation, the specific setting of each item can be comprehensively considered based on the above-mentioned multiple angles, the setting position, and the demand situation of the wearer (for example, whether the demand of the myopia, hyperopia, astigmatism, or the partial light of the eye needs to be strengthened or weakened, etc.).

[0136] It should be noted that in some other embodiments, the first pattern P1 information and the second pattern P2 information can also contain any other suitable information, which can be flexibly selected according to actual conditions and is not limited here.

[0137] It can be understood that in this embodiment, when the first pattern P1 information and the second pattern P2 information are the same, the scattering structure forms a regularly distributed area on the lens, which helps the pattern density of the scattering structure in the lens to be more consistent in each area, and helps to improve the wearing comfort.

[0138] Continuing to refer to Figure 2 It can be seen that in some other embodiments, the lines O2, O3, and O4 passing through the intersection points of the three arc lines of the shell-shaped central area C divide the entire lens body 10 into three areas: a first area D1, a second area D2, and a third area D3. The first pattern P1 information composed of the scattering structure 11 in the first sub-area D11 in the first area D1 is the same as the second pattern P2 information composed of the scattering structure 11 in the second sub-area D12 in the second area D1.

[0139] In some specific embodiments, Figure 2 The third pattern P3 information composed of the scattering structure 11 in the third sub-area D31 in the third area D3 in the entire lens body 10 can be the same as or different from the first pattern P1 information and the second pattern P2 information.

[0140] Continuing to refer to Figure 1 and Figure 2 In some embodiments, the scattering structure located on the entire lens body 10 has the same information, which includes but is not limited to material composition, size, depth, roughness, spacing, arrangement information, and optical information, etc. At this time, the first pattern P1 information located in the entire first area D1 can be the same as the second pattern P2 information located in the entire second area D2.

[0141] It can be understood that when the first pattern P1 and the second pattern P2 occupy the entire lens and contain the same information, the scattering structure forms the maximum regular arrangement on the lens, which helps the pattern density of the scattering structure in the lens to be more consistent in each area, helps to better improve the wearing comfort, and can significantly reduce the complexity of the manufacturing process and the production cost.

[0142] In addition to the above-mentioned area division, in some embodiments, as shown in Figure 10 and Figure 11 , the first area D1 and the second area D2 are both arranged around the entire central area C, and the first area D1 is located between the second area D2 and the central area C.

[0143] In this embodiment, the first area D1 located between the second area D2 and the central area C is arranged in a radial direction pointing to the lens edge along the central area C, and the scattering structure provides advantageous conditions in terms of different material compositions, sizes, depths, roughnesses, spacings, arrangement information, and optical information.

[0144] In some embodiments, as shown in Figure 10 , the first pattern P1 can include a first sub-pattern P11 adjacent to the central area C and a second sub-pattern P12 away from the central area C, and the second pattern P2 can include a third sub-pattern P21 adjacent to the first area D1 and a fourth sub-pattern P22 away from the first area D1. The first pattern P1 and the second pattern P2 and the information contained therein are the same.

[0145] In other embodiments, as shown in Figure 11 , the first pattern P1 includes multiple patterns and is symmetrically distributed about the line O5 and the line O6 passing through the central area C in a position adjacent to the central area C, and the second pattern P2 includes a third sub-pattern P21 adjacent to the first area D1 and a fourth sub-pattern P22 away from the first area D1.

[0146] In embodiments, when the multiple areas contained in the scattering area D are arranged around the central area C, the shape of the scattering structure 11 includes a regular hexagon, and multiple scattering structures 11 can be distributed in the scattering area D in the form of multiple ring structures, for example, can be arranged in the shape of the dashed line shown in Figure 10 and Figure 11 to form ring structures, and multiple ring structures in the first area D11 and the second area D12 are concentric circular rings around the central area C.

[0147] It should be noted that although only a limited number of dashed ring shapes are shown in Figure 10 and Figure 11 , this is only an exemplary illustration, and in actual operation, the number of ring structures can not be limited to the number of dashed ring shapes shown in the figures, and it can be more or fewer ring structures, which can be flexibly selected according to actual conditions, and is not specifically limited here.

[0148] Understandably, by setting the hexagonal scattering structure 11 to form a ring structure, more options are available for reducing the scattering effect and contrast in ophthalmic lenses, which helps to effectively help lens wearers suppress the development of myopia or hyperopia.

[0149] In some embodiments, when the scattering structure 11 includes a regular hexagon, a first combined pattern A1 and a second combined pattern A2, the distribution of the scattering structure 11 in the scattering region D can include various cases. Each embodiment can obtain a biomimetic structure while also achieving light optimization.

[0150] The following is a more detailed description with reference to the accompanying drawings:

[0151] In some embodiments, such as Figure 13 As shown, the scattering structure 11 is located on the entire scattering region D, and each scattering structure 11 may contain a regular hexagonal structure. The boundaries between multiple scattering structures 11 are connected to form a honeycomb structure. Thus, in the scattering region of this embodiment, the scattering structure 11 has a maximized arrangement density, and at the same time, it forms a biomimetic structure similar to the compound eye structure of an insect, which helps to achieve diffuse reflection to reduce strong light and glare, and helps the lens wearer suppress the development of myopia or hyperopia.

[0152] In some embodiments, the first combined pattern A1 may be located in the entire scattering region A1 and arranged in a honeycomb pattern.

[0153] Thus, in the scattering region of this embodiment, the scattering structure 11 has a maximized arrangement density, and at the same time, it forms a biomimetic structure similar to the compound eye structure of insects, which helps to achieve diffuse reflection to reduce strong light and glare, and helps the lens wearer suppress the development of myopia or hyperopia.

[0154] Meanwhile, in this embodiment, the individual scattering structure 11, namely the first combined pattern A1, not only has a regular hexagonal biomimetic structure itself, but also further incorporates deformations of the biomimetic structure within the biomimetic structure. This not only allows these pattern structures located within the regular hexagon to provide varying scattering effects, reducing the contrast changes of light entering the eye, but also maintains as much of the biomimetic structure's outline as possible, which helps to achieve better visual regulation effects for myopic or hyperopic patients.

[0155] In some embodiments, the second combined pattern A2 may also be located in the entire scattering region D and arranged in a honeycomb pattern.

[0156] Thus, in the scattering region of this embodiment, the scattering structure 11 has a maximum arrangement density, and at the same time, a bionic structure similar to the structure of an insect compound eye is formed, which helps to achieve the function of diffuse reflection to reduce strong light and glare, and helps the lens wearer to inhibit the development of myopia or hypermetropia.

[0157] Meanwhile, in this embodiment, the single scattering structure 11, i.e., the second combined pattern A2, includes a regular hexagonal boundary L1, which helps to make the second combined pattern A2 maintain the shape of the bionic structure, and at the same time, in the second combined pattern A2, both straight boundaries L2 and curved boundaries L3 are included, which helps to form pattern structures with adjustable scattering effects inside. Compared with the pattern structures whose boundaries are all straight boundaries, the presence of curved boundaries 13 helps to exhibit more uniform scattering characteristics in light scattering, and the scattering intensity and angular distribution are relatively stable, which helps to further exert better vision regulation effect on myopic patients or hypermetropic patients.

[0158] However, it is not limited thereto, and in other embodiments, in the embodiment in which the scattering structure 11 includes a regular hexagon, in the structure arranged in a honeycomb shape in the scattering region D, the scattering structure can include any two or more combinations in addition to the single structure of the scattering structure 11 mentioned in any of the above embodiments. The arrangement mode can be interval arrangement, but it is not limited thereto, and can also be an arrangement mode in which a local area is a single scattering structure and other areas are multiple scattering structures, or an arrangement mode in which a local area is a multiple scattering structure and other areas are a single scattering structure, etc. Specifically, it can be flexibly adjusted according to actual conditions, and is not specifically limited herein.

[0159] It can be understood that in the above multiple embodiments of the ophthalmic lens provided by the present disclosure, in which the scattering structure 11 includes a regular hexagon, the distribution state of the scattering structure 11 arranged in a honeycomb shape on the scattering region D can also exist some changes:

[0160] For example, in some other embodiments, considering the different needs of the arrangement density of the scattering structure 11 on different regions, the scattering structure 11 arranged in a honeycomb shape can also not be arranged at some positions of the scattering region D, i.e., the presence of vacancy or discrete distribution can be allowed. Specifically, it can be flexibly selected and determined according to actual conditions, and is not specifically limited herein.

[0161] In some embodiments, as shown in Figure 12 The scattering region D further includes a third region D3, the first region D1 is a near vision region of the ophthalmic lens, the second region D2 is a far vision region of the ophthalmic lens, and the third region D3 is located between the near vision region and the far vision region and arranged in a symmetrical or asymmetrical manner; wherein the first pattern P1 information and the second pattern P2 information are located at least in the region close to each other of the near vision region and the far vision region.

[0162] In some embodiments, the shape of the scattering structure 11 comprises a regular hexagon, and the boundaries between adjacent scattering structures 11 are connected to each other to form a honeycomb structure in the first area D1 as the near vision zone and the second area D2 as the distance vision zone.

[0163] It can be understood that, in some cases, considering the different requirements for the arrangement density of the scattering structure 11 on different areas, the scattering structure 11 arranged in a honeycomb shape can also not be provided at some positions of the first area D1 and the second area D2, that is, the case of allowing vacancies or discrete distribution can exist, and the specific arrangement can be flexibly selected and determined according to actual conditions, which is not limited here.

[0164] Here, the near vision zone is a near image zone, the distance vision zone is located at the upper part of the lens, the intermediate vision zone is located at the middle part of the lens, and the near vision zone is located at the lower part of the lens.

[0165] In this way, the lens wearer can directly switch without an adaptation process in the line of sight activity from the distance vision zone to the near vision zone or from the near vision zone to the distance vision zone, which helps to reduce the speed of visual decline and improve wearing comfort.

[0166] However, it is not limited to this, and in other embodiments, the first pattern P1 and the second pattern P2 can also be located in areas where the near vision zone and the distance vision zone are away from each other and contain the same information.

[0167] In this way, the pattern design in the area where the near vision zone and the distance vision zone are close to each other can be designed to have different pattern information composed of different scattering structures according to the different contrast conditions of the light in the near vision zone or the distance vision zone, which helps to avoid the case of light contrast jumping when the lens wearer switches from the distance vision zone to the near vision zone or from the near vision zone to the distance vision zone, which helps to reduce the speed of visual decline and improve wearing comfort.

[0168] In yet other embodiments, the first pattern P1 and the second pattern P2 can also be located in the entire near vision zone and the entire distance vision zone and contain the same information.

[0169] In this way, the pattern information composed of the scattering structure 11 in the near vision zone and the distance vision zone can have a high degree of consistency, that is, a regular arrangement, so that the lens wearer can have a relatively stable contrast perception when looking at different areas of the near vision zone and the distance vision zone during lens wearing, which helps to reduce the speed of visual decline and improve wearing comfort.

[0170] In some embodiments, the third region D3 contains third pattern P3 information, which is at least partially the same as the first pattern P1 information and the second pattern P2 information. For example, they may be partially or completely the same, but are not limited thereto. In some other embodiments, the above relationship may also be different.

[0171] Thus, when the differences are not apparent, it can help to make targeted designs based on the actual situation. When the differences are similar, the pattern information composed of scattering structures 11 in the near vision zone and the far vision zone can have a high degree of consistency, that is, they are arranged in a regular manner. This allows the wearer to have a relatively stable contrast perception when looking at any different area of ​​the lens except for the central area C during the wearing process, which helps to slow down the rate of vision decline and improve wearing comfort.

[0172] In some embodiments, the first pattern P1 information and the second pattern P2 information include material composition, size, depth, roughness, spacing, arrangement information and optical information.

[0173] Figure 7 Schematic diagrams of patterns composed of various scattering structures provided for different embodiments of this disclosure;

[0174] like Figure 7 As shown in Figures (3) and (1), in the F direction from the central region to the edge region of the lens, the size of the scattering structure 11 near the central region C is smaller than (see Figures (3) and (1) for details). Figure 7 (3) in the figure) or equal to (please refer to the figure for details) Figure 7 The size of the scattering structure 11 far from the central region C in Figure (1) is shown.

[0175] In this way, the amount of light entering the central region C after passing through the scattering structure 11 can be reduced, thereby effectively maintaining the visual acuity of the central region C while reducing the light contrast around the retina.

[0176] In other embodiments, in the F direction from the central region to the lens edge region, such as Figure 7 As shown in Figure (2), the size distribution density of the scattering structure 11 near the central region C can be smaller than the distribution density of the scattering structure 11 far from the central region C.

[0177] In this way, the amount of light entering the central region C after passing through the scattering structure 11 can be reduced, thereby effectively maintaining the visual acuity of the central region C while reducing the light contrast around the retina.

[0178] It is understood that, in any embodiment of the lens structure provided in this disclosure, the pattern composed of multiple scattering structures 11 located in any region of any scattering region D can be adopted. Figure 7at least one of the arrangement modes shown or a combination thereof. In addition, in the embodiment comprising the connecting structure, the pattern of the plurality of scattering structures 11 and the connecting structure 12 located in any scattering region D can adopt Figure 8 at least one of the arrangement modes shown or a combination thereof. In addition, in the embodiment comprising the connecting structure, the pattern of the plurality of scattering structures 11 and the connecting structure 12 located in any scattering region D can adopt Figure 7 and Figure 8 any combination between the various patterns contained in (3) and (1) of

[0179] In some specific embodiments, for example, in the embodiment in which the first region D1 is located between the central region C and the second region D2, as shown in (3) and (1) of Figure 7 in the first region D1, the size of the scattering structure 11 close to the central region C is smaller than (for details, please refer to (3) of Figure 7 ) or equal to (for details, please refer to (1) of Figure 7 ) the size of the scattering structure 11 away from the central region C.

[0180] It should be noted that in the embodiments of the present disclosure, the lines O1, O2, O3, O4, O5, O6 are only exemplary indications, and the upper and lower or left and right relationships shown in the drawings and the proportion of the occupied area of the ophthalmic lens are only exemplary descriptions, and do not constitute the only limitation of the relative position relationship between the ophthalmic lens and the eye position of the user, the proportion of the area occupied by the lens, etc. In actual operation, the above-mentioned content can be flexibly selected according to the actual situation, which is not limited here.

[0181] It should be noted that in the embodiments of the present disclosure, the technical features between the technical solutions described in each embodiment can be combined arbitrarily without conflict.

[0182] The above is only a preferred embodiment of the present disclosure, and is not intended to limit the protection scope of the present disclosure. Any modification, equivalent replacement and improvement made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
