[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

[0039] 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 illustration of the purpose of the present disclosure, and should not be regarded as an improper limitation of the present disclosure.

[0040] At present, most of the techniques for slowing down myopia deepening of eye health are pre-film defocus techniques, which form a defocus type number on the retina periphery by arranging a plurality of micro-lenses on the lens, so as 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 the axial growth and achieve the condition of preventing and controlling the deterioration of vision.

[0041] Based on this, the following technical solutions of the embodiments of the present disclosure are proposed:

[0042] The embodiments of the present disclosure provide an ophthalmic lens, comprising:

[0043] A lens body, the lens body at least comprising a central region and a scattering region arranged around the central region, the scattering region at least comprising a first region and a second region;

[0044] A plurality of scattering structures located in the scattering region, the plurality of scattering structures being located at least in the first region and the second region.

[0045] 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.

[0046] 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, the contrast of light around the retina is effectively reduced, optimizing the light entering the eye. In other words, the ophthalmic lens with scattering structures achieves light optimization, which helps reduce abnormal changes in axial length caused by high light contrast, such as elongation or shortening of the axial length, thus helping to 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.

[0047] 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.

[0048] Figure 1 This is a schematic diagram of the structure of an ophthalmic lens provided in an embodiment of the present disclosure; Figure 2 This is a schematic diagram of the structure of another ophthalmic lens provided in an embodiment of the present disclosure; Figure 3 and Figure 4 For along Figure 1 A schematic diagram of the partial structure of an ophthalmic lens taken along the B1-B2 direction; Figure 5 This is a schematic diagram of the scattering structure provided in an embodiment of the present disclosure; Figure 6 A schematic cross-sectional view of the scattering structure provided in an embodiment of this disclosure; Figure 7 This is a schematic diagram of a pattern composed of scattering structures provided in an embodiment of the present disclosure; Figure 8 A schematic diagram of another pattern composed of scattering structures provided in an embodiment of this disclosure; Figure 9 A cross-sectional schematic diagram of the connection structure provided in an embodiment of this disclosure; Figure 10 A schematic diagram illustrating a configuration of a first pattern and a second pattern according to an embodiment of this disclosure; Figure 11Another structure schematic diagram of the setting mode of the first pattern and the second pattern provided by the embodiment of the present disclosure is provided. Figure 12 Another structure schematic diagram of the setting mode of the first pattern and the second pattern provided by the embodiment of the present disclosure is provided.

[0049] The ophthalmic lens provided by the embodiment of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0050] 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;

[0051] 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;

[0052] wherein 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.

[0053] The lens provided by the embodiment of the present disclosure can be used as a lens for inhibiting the development of myopia or hyperopia.

[0054] In some embodiments, the ophthalmic lens can be a spectacle lens or a contact lens (for example, 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.

[0055] Here, the central region C can be understood as the 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.

[0056] 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. In some embodiments, the arrangement shape of the scattering structures 11 in the scattering region D can include one of a circle, an ellipse, a conchiform shape or a regular hexagon.

[0057] In this way, the central region C and the scattering region D can contain a variety of possible shapes, and in some cases, the arrangement shape of the scattering structures 11 in the scattering region D can be set following the shape of the central region C, that is, the arrangement shape can be the same as the shape of the central region C, but is not limited thereto, and in other cases, the two can also be different. Specifically, it can be flexibly selected according to actual conditions, which is not specifically limited here.

[0058] In addition, when at least one of the arrangement shape of the central region C and the scattering structure 11 in the scattering region D comprises a regular hexagon, a bionic structure similar to an insect compound eye structure is included in the ophthalmic lens, 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.

[0059] It can be seen that the ophthalmic lens provided by the embodiments of the present disclosure can not only obtain the light optimization effect by introducing the scattering structure, but also can make the final ophthalmic lens have a plurality of beneficial functions by introducing the bionic structure, which helps the lens wearer to inhibit the development of myopia or hypermetropia from multiple aspects.

[0060] In some embodiments, the scattering region D can be located in the region of the lens except the central region C. However, it is not limited thereto, and in other embodiments, the lens can also comprise an edge region (not shown in the figure), and the scattering region D is located between the central region C and the edge region (not shown in the figure).

[0061] In some embodiments, when the lens comprises an edge region (not shown in the figure), any required pattern structure can be included on the edge region (not shown in the figure), or the edge region (not shown in the figure) can also not include a pattern structure, which can be determined according to actual needs, and is not specifically limited here.

[0062] Figure 3 Structure schematic diagram of scattering structure 11 provided in different positions for myopia lens; Figure 4 Structure schematic diagram of scattering structure 11 provided in different positions for hypermetropia lens. It should be noted that the mode provided by the embodiments of the present disclosure can also be used on any type of lens requiring a scattering structure, which is not enumerated here. In the above-mentioned lenses, the related information of the scattering structure 11 contained can be set with reference to the content of any embodiment of the present disclosure. Figure 5 The structure schematic diagram of a single scattering structure 11 in different embodiments is mainly shown in

[0063] It should be noted that in Figure 5 , in order to clearly show the specific structure of the scattering structure, a plurality of information about the type of lens, the information of the curved surface and the setting position are omitted.

[0064] In some embodiments, as shown in Figure 3 and Figure 4 , the scattering structure 11 can be provided on the front surface of the lens (for details, please refer to (1) of Figure 3 and (1) of Figure 4 ), the back surface, and the bonding surface of the two layers of lens materials (for details, please refer to (2) and (3) of Figure 3 and (2) and (3) of Figure 4 ).

[0065] In some embodiments, as shown in FIG. 1A and FIG. 1B, the scattering structure 11 includes at least one of a recess (see FIG. 2A, FIG. 2B and FIG. 2C) or a light-shielding material (see FIG. 3A, FIG. 3B and FIG. 3C). Figure 3 and Figure 4 In some embodiments, as shown in FIG. 2A, FIG. 2B and FIG. 2C, the scattering structure 11 includes a recess. Figure 3 、 Figure 4 、 Figure 5 In some embodiments, as shown in FIG. 3A, FIG. 3B and FIG. 3C, the scattering structure 11 includes a light-shielding material. Figure 5 、

[0066] In some embodiments, when the scattering structure 11 is located on the bonding surface of two lens materials, the recess direction of the scattering structure can be towards the material with high refractive index, for example:

[0067] In some embodiments, as shown in FIG. 2B and FIG. 3B, the lens body 10 includes a first lens material 101 and a second lens material 102, and when the refractive index of the first lens material 101 is greater than the refractive index of the second lens material 102, the recess direction of the scattering structure 11 is towards the first lens material 101. Figure 3 、 Figure 4 In some embodiments, as shown in FIG. 2C and FIG. 3C, the lens body 10 includes a first lens material 101 and a second lens material 102, and when the refractive index of the first lens material 101 is less than the refractive index of the second lens material 102, the recess direction of the scattering structure 11 is towards the second lens material 102.

[0068] In some embodiments, as shown in FIG. 2C and FIG. 3C, the lens body 10 includes a first lens material 101 and a second lens material 102, and when the refractive index of the first lens material 101 is less than the refractive index of the second lens material 102, the recess direction of the scattering structure 11 is towards the second lens material 102. Figure 3 、 Figure 4 In some embodiments, the scattering structure 11 can be a recess structure realized by a laser.

[0069] In some embodiments, as shown in FIG. 2A, FIG. 2B and FIG. 2C, the scattering structure 11 includes a recess.

[0070] In some embodiments, as shown in FIG. 2A, FIG. 2B and FIG. 2C, the scattering structure 11 includes a recess. Figure 3 and Figure 4 In some embodiments, as shown in FIG. 2A, FIG. 2B and FIG. 2C, the scattering structure 11 includes a recess.

[0071] 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 and the lens body. 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.

[0072] In some embodiments, the light-blocking material can be formed on the surface of the lens body 10 by material growth.

[0073] In some embodiments, the scattering structure 11 can also be obtained by a mask etching process after it has been designed.

[0074] In some embodiments, the light-shielding material may include, but is not limited to, a chromium layer.

[0075] Here, the light-blocking material reduces the contrast of light around the retina by decreasing the transmittance of incident light, thereby effectively slowing down the decline in vision for the lens wearer.

[0076] Understandably, when the scattering structure 11 is a light-shielding material, the original structure of the front and back surfaces of the lens itself will not be destroyed, which helps the lens maintain stability and good optical performance when used by the wearer. Moreover, the contrast of light around the retina can be significantly reduced, thereby reducing the light signal of the peripheral retina to control the growth or shortening of the axial length, thus achieving the effect of preventing myopia or hyperopia from worsening.

[0077] In some embodiments, such as Figure 6 As shown, regardless of whether the scattering structure 11 is a recessed structure or a light-shielding material, the cross-sectional shape of the scattering structure can include at least one or a combination of circular, elliptical, triangular, regular hexagonal, quadrilateral, polygonal and irregular shapes.

[0078] Thus, in this embodiment of the present disclosure, the cross-sectional shape of the scattering structure 11 can include a variety of possible shapes. When at least one of the arrangement shape of the central region C and the scattering structure 11 in the scattering region D and the cross-sectional shape of the scattering structure 11 includes a regular hexagon, the ophthalmic lens contains a biomimetic structure similar to the compound eye structure of an insect, which helps to achieve diffuse reflection to reduce strong light and glare, alleviate visual fatigue, and help the lens wearer suppress the development of myopia or hyperopia.

[0079] It can be seen that the ophthalmic lens provided by the embodiments of the present disclosure, in addition to the light optimization effect obtained by introducing the scattering structure, also has a plurality of beneficial functions by introducing the bionic structure, which helps to inhibit the development of myopia or hyperopia from multiple aspects.

[0080] In some embodiments, the average value of the size of the shape of the portion where the scattering structure intersects the lens body ranges between 0.1 mm and 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.

[0081] 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.

[0082] In some embodiments, the combination of the first sub-layer L1 and the second sub-layer L2 can include a combination of two or more of the material of the lens body itself, the material from the outside with a preset structure (for example, a film layer), the material with a scattering effect located inside the lens body, the light shielding material, the material deposited from the outside, other optical materials, or the material that is easy to be photo-catalyzed or heat-catalyzed to be shaped, etc.

[0083] 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 shielding material; or the first sub-layer L1 can be the material of the lens body 10, and the second sub-layer L2 can be an external deposited material with a refractive index less than 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 shielding material, an external deposited material, other optical materials, or a material that is easy to be photo-catalyzed or heat-catalyzed to be shaped; or the first sub-layer L1 can be one or more of an external deposited material, other optical materials, or a material that is easy to be photo-catalyzed or heat-catalyzed to be shaped, and the second sub-layer L2 can be a light shielding material; or the first sub-layer L1 can be a light shielding material, and the second sub-layer L2 can be one or more of an external deposited material, other optical materials, or a material that is easy to be photo-catalyzed or heat-catalyzed to be shaped.

[0084] Continuing to refer to Figure 5 In some embodiments, the second sub-layer L2 includes a void structure H, and the void structure H does not expose the first sub-layer L1 (for details, please refer to Figure 5Fig. 2 and Fig. 5 in the drawings);

[0085] or,

[0086] The void structure H exposes the first sub-layer L1 (for details, please refer to Figure 5 Fig. 3 and Fig. 6 in the drawings).

[0087] It can be understood that when the second sub-layer L2 contains the void structure H but the void structure H does not expose the first sub-layer L1, the material for scattering light at the surface layer is still the second sub-layer L2, which can have the same refractive index, but at the same time, due to the increase 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, which can have a higher scattering effect, thereby helping to obtain a better contrast reduction effect.

[0088] 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 at the surface layer can be a case containing two refractive indexes. Compared with the case where the surface for scattering light contains only one refractive index material, the scattering effect of the scattering structure 11 provided by the embodiment on the incident light can have multiple forms, which helps to select the required materials of the two sub-layers or the specific position of the exposed first sub-layer according to the required scattering effect, such as strengthening, weakening, or regular or irregular changes, etc., so as to obtain the required scattering effect of the lens.

[0089] In addition to the above structure, in some embodiments, in the same area or different areas, the void structure H included 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.

[0090] 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.

[0091] 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 material 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.

[0092] In some embodiments, asFigure 8 As shown, the scattering region D further comprises connecting structures 12 connecting at least part of the scattering structures 11.

[0093] In some embodiments, the connecting structures 12 are located at least one of on the surface or inside the lens body.

[0094] In some embodiments, the connecting structures can have the same or different shape and material settings as the scattering structures. In some embodiments, the connecting structures can also have the same structure and material settings as the scattering structures, and even can have part or all of the same multi-layer structure settings as the scattering structures.

[0095] As shown, in some embodiments, the cross-sectional shape of the connecting structures 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. Figure 9

[0096] In any of the above embodiments, when the connecting structures 12 comprise a regular hexagon, the position and area of the bionic structure in the ophthalmic lens are further increased, which helps to further achieve the function of diffuse reflection to reduce strong light and glare, and slow down visual fatigue, thereby further helping the lens wearer to inhibit the development of myopia or hyperopia.

[0097] As can be seen, the ophthalmic lens provided by the embodiments of the present disclosure can have multiple beneficial functions in addition to the light optimization effect of introducing the scattering structure, which helps to help the lens wearer inhibit the development of myopia or hyperopia from multiple aspects.

[0098] In some embodiments, the area where the connecting structures 12 are arranged between the scattering structures 11 can be located on the entire scattering region D, but is not limited thereto, and in other embodiments, the area where the connecting structures 12 are arranged between the scattering structures 11 can also be located on part of the scattering region D.

[0099] In some embodiments, the connecting structures 12 can have the function of reducing the contrast of 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.

[0100] As can be understood, when the connecting structures 12 are arranged between the scattering structures 11 in the scattering region D and have the function of reducing the contrast of incident light at different positions of the lens, the number and density of the scattering structures for reducing the contrast of incident light at different regions of the lens are effectively increased, which can effectively delay the deterioration of the wearer's vision.

[0101] ​For ease of reference, multiple scattering structures arranged around the central region C and located on the same scattering trajectory can be called a group of scattering structures, for example... Figure 8 The first scattering structure R1, the second scattering structure R2, and the third scattering structure R3 are shown in the figure.

[0102] In some embodiments, the connection structure 12 may be located between two adjacent scattering structures 11 in the same set of scattering structures (see details). Figure 8 (Figure 1) in the middle.

[0103] However, this is not the only one; in other embodiments, it may also be possible to... Figure 8 The connection between two adjacent scattering structures 11 in Figure (1) is extended to the case where there is a connection structure between two adjacent scattering structures 11 in adjacent positions. For example:

[0104] In some embodiments, such as Figure 8 As shown in Figure (2), the connecting structure 12 connects two scattering structures 11 that are in adjacent positions between the two sets of scattering structures.

[0105] In addition to the above methods, in order to ensure that the density of the scattering structure 11 and the connecting structure 12 is not too high, so as to reduce the conspicuousness of the structure in the scattering region D, the arrangement relationship between the scattering structure 11 and the connecting structure 12 can be handled as follows:

[0106] In some embodiments, such as Figure 8 As shown in Figure (3), multiple connecting structures 12 connect two scattering structures 11 that are adjacent to each other between two groups of scattering structures. The scattering structures connected by the connecting structures 12 are arranged at intervals in the same group of scattering structures. Multiple connecting structures 12 that connect two adjacent groups of scattering structures are defined as the same group of connecting structures. At least in some regions, no connecting structures 12 are set in the adjustment region A between the two groups of connecting structures 12.

[0107] In this way, while setting the connection structure 12 to enhance the scattering effect in certain areas, it is possible to ensure that the structural density in the scattering area does not increase too much, which helps to reduce the light contrast around the retina and also helps to improve the aesthetics of wearing the garment.

[0108] In other embodiments, such as Figure 8 As shown in Figure (4), Figure 8 Figure (4) in the middle and Figure 8Compared with the (3) of FIG. 1, the difference 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 with the connecting structure 12 are transferred to the position where the adjustment region A is located (for example, the first sub-structure 111 in the scattering structure 11 connected with 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 region A), so as to further balance the relationship between the strengthening of the scattering effect and the fact that the density does not increase too much.

[0109] In still other embodiments, as shown in the (5) of FIG. 1, Figure 8 Compared with the (4) of FIG. 1, Figure 8 Compared with the (5) of FIG. 1 and Figure 1 Compared with the (4) of FIG. 1, the difference 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 with the connecting structure 12 are all transferred to the position where the adjustment region A is located, so as to further balance the relationship between the strengthening of the scattering effect and the fact that the density does not increase too much.

[0110] In the embodiments of the present disclosure, regarding the distribution and division of the first region and the second region, various cases can be included, and the various cases that the first region and the second region can exist will be further described in detail below in combination with the drawings:

[0111] 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 P2 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.

[0112] Meanwhile, in the embodiments of the present disclosure, the first pattern P1 information and the second pattern P2 information are the same, which simultaneously 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.

[0113] In addition, if there are other pattern information in the embodiments, they can be understood in the above-mentioned manner.

[0114] 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, which can be flexibly selected according to actual needs and is not limited herein.

[0115] With reference back to Figure 2 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: a first region D1 and a second region D2, respectively. 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.

[0116] 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.

[0117] In some embodiments, the material of the lens includes, but is not limited to, a resin material or an optical glass material, etc.

[0118] It can be understood that the greater the depth, the stronger the scattering effect on the light; the greater the roughness, the stronger the scattering effect on the 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, affecting the wearing aesthetics; the arrangement information can include the results 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.

[0119] Therefore, in actual operation, the specific setting of each item can be comprehensively considered based on the above-mentioned multiple angles, and the needs of the wearer (such as myopia, hyperopia, astigmatism, or whether the light needs to be strengthened or weakened in the local eye, etc.) are comprehensively considered.

[0120] It should be noted that, in some other embodiments, the first pattern P1 information and the second pattern P2 information can also include any other suitable information, which can be flexibly selected according to actual conditions and is not specifically limited herein.

[0121] 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 region on the lens, which helps the pattern density of the scattering structure in the lens to be more uniform in the distribution of each region, and helps to improve the wearing comfort.

[0122] With reference back to Figure 2As can be seen, in other embodiments, the lines O2, O3, O4 passing through the intersection points of the three arc segments of the shell-shaped central region C divide the entire lens body 10 into three regions: a first region D1, a second region D2, and a third region D3. 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.

[0123] In some specific embodiments, Figure 1 The third pattern P3 information composed of the scattering structures 11 in the third sub-region D31 in the third region D3 in the lens body 10 can be the same as or different from the first pattern P1 information and the second pattern P2 information.

[0124] With reference to Figure 2 and Figure 10 , in some embodiments, the scattering structures on the entire lens body 10 have the same information, including but not limited to material composition, size, depth, roughness, spacing, arrangement information, and optical information. At this time, the first pattern P1 information on the entire first region D1 can be the same as the second pattern P2 information on the entire second region D2.

[0125] 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 structures form the most regular arrangement on the lens, which helps to achieve a high degree of consistency in the pattern density of the scattering structures in each region, helps to better improve the wearing comfort, and can significantly reduce the complexity of the manufacturing process and the production cost.

[0126] In addition to the above-mentioned region division, in some embodiments, as shown in Figure 11 and Figure 10 , the first region D1 and the second region D2 are both arranged around the entire central region C, and the first region D1 is located between the second region D2 and the central region C.

[0127] In this embodiment, the arrangement of the first region D1 between the second region D2 and the central region C provides favorable conditions for the scattering structures to provide different material compositions, sizes, depths, roughnesses, spacings, arrangement information, and optical information in the radial direction of the central region C pointing to the edge of the lens.

[0128] In some embodiments, as shown in Figure 11As shown, the first pattern P1 can include a first sub-pattern P11 adjacent to the central region C and a second sub-pattern P12 away from the central region C, and the second pattern P2 can include a third sub-pattern P21 adjacent to the first region D1 and a fourth sub-pattern P22 away from the first region D1. The first pattern P1 and the second pattern P2 and the information contained in each are the same.

[0129] In some embodiments, as shown, Figure 12 the first pattern P1 includes a plurality of patterns and is symmetrically distributed about lines O5 and O6 passing through the central region C at positions adjacent to the central region C, and the second pattern P2 includes a third sub-pattern P21 adjacent to the first region D1 and a fourth sub-pattern P22 away from the first region D1.

[0130] In some embodiments, as shown, Figure 7 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 distance vision region of the ophthalmic lens, and the third region D3 is located between the near vision region and the distance vision region and is symmetrically arranged or asymmetrically arranged; wherein the first pattern P1 information and the second pattern P2 information are located in at least a region where the near vision region and the distance vision region are close to each other.

[0131] Here, the near vision region is a near distance image region, the distance vision region is located at the upper part of the lens, the intermediate vision region is located at the middle part of the lens, and the near vision region is located at the lower part of the lens.

[0132] In this way, the lens wearer can directly switch without having to adapt when switching from the distance vision region to the near vision region or vice versa, which helps to reduce the speed of vision decline and improve wearing comfort.

[0133] However, this is not limiting, and in other embodiments, the first pattern P1 and the second pattern P2 can also be located in a region where the near vision region and the distance vision region are away from each other and contain the same information.

[0134] In this way, the pattern design in the region where the near vision region and the distance vision region are close to each other can be designed differently according to the different contrast of light in the near vision region or the distance vision region, which helps to avoid the jump in light contrast when the lens wearer switches from the distance vision region to the near vision region or vice versa, which helps to reduce the speed of vision decline and improve wearing comfort.

[0135] In yet other embodiments, the first pattern P1 and the second pattern P2 can also be located in the entire near vision region and the entire distance vision region and contain the same information.

[0136] In this way, 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 different areas of the near vision zone and the far vision zone during the wearing process, which helps to slow down the rate of vision decline and improve wearing comfort.

[0137] In some embodiments, the third region D3 contains third pattern P3 information, which may be the same as or different from the first pattern P1 information and the second pattern P2 information.

[0138] 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.

[0139] 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.

[0140] Figure 7 Schematic diagrams of patterns composed of various scattering structures provided for different embodiments of this disclosure;

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] It can be understood that in the lens structure provided in any embodiment of the present disclosure, the pattern composed of the plurality of scattering structures 11 in any area of any scattering region D can adopt at least one of the arrangement modes shown in Figure 8 , or a combination thereof. In addition, in the embodiment comprising the connecting structure, the pattern composed of the plurality of scattering structures 11 and the connecting structure 12 in any scattering region D can adopt at least one of the arrangement modes shown in Figure 7 , or a combination thereof. In addition, the pattern composed of the plurality of scattering structures 11 and the connecting structure 12 in any scattering region D can also be any combination between the various patterns contained in Figure 8 and Figure 7 .

[0146] In some specific embodiments, for example, in the embodiment in which the first area D1 is located between the central region C and the second area D2, as shown in (3) and (1) of Figure 7 , in the first area 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 ​ ) the size of the scattering structure 11 away from the central region C.

[0147] 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 area occupied by the ophthalmic lens in the drawings 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.

[0148] It should be noted that in the embodiments of the present disclosure, the technical features in the technical solutions described in each embodiment can be combined arbitrarily without conflict.

[0149] 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.
