Description

[Technical Field]

[0001] (Cross-reference of related applications) This application claims priority to Chinese patent applications 202210421560.9, 202220928567.5, 202310369818.X, and 202320781318.2, filed on 21 April 2022, and all contents of the aforementioned patent applications are incorporated into this application by reference. This disclosure relates to the field of optics, and more specifically to lens elements, optical lens groups, molds, and eyeglasses. [Background technology]

[0002] Related technologies include lenses that have the function of suppressing the progression of refractive errors such as nearsightedness and farsightedness in the human eye.

[0003] For example, a lens described in the specification of Chinese Patent Application Publication No. 104678572 is known. This patent describes an eyeglass lens comprising: a first refractive region having a first refractive power based on a prescription for correcting refractive errors of the eye; and a second refractive region having a refractive power different from the first refractive power and having the function of focusing on a location other than the retina of the eye in order to suppress the progression of refractive errors of the eye, wherein the second refractive region is formed as a plurality of island-like regions that are spaced apart from each other and are independent near the center of the lens, and the first refractive region is formed as a region other than the region formed as the second refractive region.

[0004] For example, the eyeglasses described in the patent document specification of Chinese Patent No. 109716212 include an ophthalmic lens attached to an eyeglass frame, the ophthalmic lens having dimensions in the range of 0.1 mm to 0.5 mm and including a plurality of light scattering centers spaced at intervals of 0.8 mm or less, and with respect to incident light that passes through each ophthalmic lens, the ophthalmic lens scatters the light incident on the light scattering centers. [Overview of the project]

[0005] The inventors found that eyeglasses, developed prior to the filing date, which have a function to focus on a location other than the retina of the eye in order to suppress the progression of refractive errors, can suppress the progression of refractive errors, but the structural characteristics of the surface of the lens element unnecessarily reduce visual clarity.

[0006] Specifically, the cross-sectional view of the lens element of the related technology (for example, Chinese Patent Application Publication No. 104678572) is shown in Figures 1 and 2, and the spectacle lens 10 is a lens that corrects myopia and suppresses the progression of myopia. The spectacle lens 10 has a base region 1 and a plurality of spaced-apart and independent island-like regions 2, of which the base region 1 has a first refractive power based on a prescription for correcting myopia, and the island-like regions have the function of focusing on a position other than the retina of the eye in order to suppress the progression of refractive errors of the eye. The plurality of island-like regions 2 are arranged almost uniformly near the center of the lens so that they are spaced apart from each other by a distance r of approximately the same value as the radius d / 2. The plurality of island-like regions 2 are formed to fit within a circular region of radius R (20 mm or less) centered on the optical center O of the lens, and are arranged to form, for example, a hexagon inscribed in a circle of radius R.

[0007] The inventors found that while lenses of related technologies can be used in practical applications to suppress the progression of myopia, such lenses reduce the wearer's visual clarity and do not provide a satisfactory wearing experience.

[0008] Similarly, the inventors have found that in actual applications, the related technology in Chinese Patent No. 109716212 also has a similar problem, in which its lenses reduce the wearer's visual clarity and fail to provide a satisfactory wearing experience.

[0009] To solve the above technical problems, this application provides an innovative lens element that can suppress the progression of myopia, give the wearer good visual clarity, and provide a comfortable wearing experience.

[0010] In a first aspect, the present application is a base region including a prescription region for correcting refractive errors of the eye, and a plurality of island regions including regions for suppressing the progression of refractive errors of the eye, and provides a lens element in which at least some of the island regions are adjacent to each other and have a shared edge.

[0011] In some embodiments, the present application is a base region including a prescription region for correcting refractive errors of the eye, and a plurality of island regions including regions for suppressing the progression of refractive errors of the eye, and provides a lens element in which at least some of the island regions are adjacent to each other and have a shared edge, and for all edges of the island regions on the lens element, the length of the shared edge portion is L1, the length of the non-shared edge portion is L2, and the ratio of L1 to L2 is 0.1 or more.

[0012] In some embodiments, the present application is a base region including a prescription region for correcting refractive errors of the eye, and a plurality of island regions including regions for suppressing the progression of refractive errors of the eye, and provides a lens element in which at least some of the island regions are adjacent to each other and have a shared edge, and for all edges of the island regions on the lens element, the length of the shared edge portion is L1, the length of the non-shared edge portion is L2, and the ratio of L1 to L2 is 0.2 or more.

[0013] In some embodiments, the present application is a base region including a prescription region for correcting refractive errors of the eye, and a plurality of island regions including regions for suppressing the progression of refractive errors of the eye, and provides a lens element in which at least some of the island regions are adjacent to each other and have a shared edge. The present invention provides a lens element in which, for all island-shaped regions on the lens element, the length of the shared edge portion is L1, the length of the non-shared edge portion is L2, and the ratio of L1 to L2 is 0.3 or greater.

[0014] Through extensive research and practice, the inventors discovered that one of the key factors causing lenses to reduce the wearer's visual clarity in related technologies is the boundary between the island regions and the base region, i.e., the edge of the island regions. Because the base region and the island regions have different refractive powers, the edge of the island regions becomes the boundary between the two types of refractive powers. This boundary is a refractive power transition region, which does not have favorable optical properties and reduces the wearer's visual clarity. When the island regions on the lens are spaced apart and independent of each other, each island region on the lens has its own edge, resulting in an excessive refractive power transition region on the lens and reducing the wearer's visual clarity.

[0015] Figure 3 shows a magnified view of a spectacle lens of the related technology. As shown in Figure 3, there are five island-like regions (70a, 70b, 70c, 70d, 70e) that are spaced apart from each other and independent on the lens, and if the edges of each island-like region and the base region have a circumference L, then the total circumference of the edges of the five island-like regions is 5L.

[0016] The innovative lens element of the present invention solves the above problems. In the lens element of the present invention, at least some island-like regions are adjacent to each other and have shared edges. In this way, the number of edges of the island-like regions is significantly reduced without reducing the number of island-like regions, thereby improving the wearer's visual clarity.

[0017] Figure 5 shows an abstract planar schematic diagram of an island-shaped region according to an embodiment of the present invention. As shown in Figure 5, there are five island-shaped regions (50a, 50b, 50c, 50d, 50e) sharing an edge on the optical lens. Island-shaped region 50a and island-shaped region 50b have a shared edge ab, island-shaped region 50a and island-shaped region 50e have a shared edge ae, island-shaped region 50b and island-shaped region 50e have a shared edge be, island-shaped region 50c and island-shaped region 50e have a shared edge ce, island-shaped region 50c and island-shaped region 50d have a shared edge cd, and island-shaped region 50d and island-shaped region 50e have a shared edge de. By sharing an edge, these five island-shaped regions (50a, 50b, 50c, 50d, 50e) significantly reduce the total perimeter of the edge. For island-like regions (50a, 50b, 50c, 50d, 50e) that share an edge, the length of the shared edge portion is (ab + ae + be + ce + cd + de), and edges other than the shared edge are non-shared edge portions. For all island-like regions on the lens element, the length of the shared edge portion is L1, and the length of the non-shared edge portion is L2. It should be emphasized that a ratio of L1 to L2 of 0.3 or greater is particularly important for substantially improving visual clarity. Substantial improvement in visual clarity here means an improvement in visual clarity that the wearer can clearly perceive. Experiments have shown that when the ratio of L1 to L2 is less than the threshold of 0.3, the wearer's visual clarity cannot be substantially improved.

[0018] In some embodiments, the island-like region is A first island-like region positioned to scatter incident light and suppress the progression of refractive errors in the eye, and / or It includes a second island-like region positioned to focus light at a location other than the retina of the eye, thereby suppressing the progression of refractive errors in the eye.

The second refractive power is different from the first refractive power.

[0067] The inventors have further discovered that eyeglasses, developed prior to the filing date, which have a function to focus on a location other than the retina of the eye in order to suppress the progression of refractive errors, can suppress the progression of refractive errors, but they also reduce the wearer's visual clarity to some extent.

[0068] Based on the principles of vision generation, the inventor recognized that the observer's left and right eyes each view objects at different angles, and the world perceived by the brain is a mixture of both.

[0069] The inventor utilizes the above principle to provide a novel optical lens group and eyeglasses. When a wearer wears these eyeglasses, areas of reduced clarity in the left eye are compensated for by the right eye, and areas of reduced clarity in the right eye are compensated for by the left eye, resulting in a unique complementary relationship between the left and right eyes. Ultimately, the signals received by both eyes are integrated and then fed back to the brain, allowing the brain to still obtain relatively clear and complete target information.

[0102] Embodiments of the present invention will be described in detail below with reference to examples, but it will be understood by those skilled in the art that the following examples are merely for illustrative purposes and should not be considered to limit the scope of the present invention.

[0103] As used herein, “around,” “about,” or “approximate” typically means within a 20 percent deviation, preferably within a 10 percent deviation, and more preferably within a 5 percent deviation of a given value or range. The numbers given herein are approximations that implicitly include the terms “degree,” “about,” or “approximately” (unless such terms are explicitly stated).

[0104] In this invention, the technical features (e.g., structure, dimensions, parameters, performance, etc.) of the subject matter—lens elements, optical lens groups, and eyeglasses—have been described. However, those skilled in the art should understand that some inaccuracies may exist in actual production. Therefore, if the difference between one subject and one of the solutions described in this invention falls within the range of manufacturing or operational tolerances desired in the art (e.g., within ±5%, within ±3%, or within ±1%), then this subject should be considered to constitute the same or equivalent solution as the technical solution of this invention.

[0105] In this invention, the term “part” means a range greater than 0% and less than 100%, such as 1% to 10%, 10% to 20%, 20% to 30%, 30% to 40%, 40% to 50%, 50% to 60%, 60% to 70%, 70% to 80%, 80% to 90%, or 90% to 99%.

[0106] Similarly, the elements and components of this disclosure will be described using the terms "one" or "one kind" for convenience and to give a general meaning to the disclosure. Unless otherwise explicitly stated, such descriptions should be understood to include one or at least one, and the singular simultaneously includes the plural.

[0107] It should be understood that the directions or positional relationships indicated by terms such as "center point," "vertical direction," "horizontal direction," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," and "outside" are based on the drawings and are merely for the purpose of easily explaining the present invention and simplifying the description. They do not explicitly or implicitly suggest that the described devices or elements necessarily have a specific direction or are configured and operated in a specific direction, and therefore should not be understood as limiting the claims of the present invention.

[0108] It should be understood that, in the drawings of this application, some structural features are intentionally enlarged to help the reader more clearly identify them, and as a result, the scale of some drawings differs from that of the actual product. Those skilled in the art should understand that the above scales are enlarged or reduced simply for the purpose of more clearly illustrating certain structural features.

[0109] Figure 4 shows a lens element according to several embodiments of this application. As shown in the figure, the lens element 10 includes a base region 55 and a plurality of island regions 50. The base region 55 is a prescription region that corrects refractive errors of the eye. The island regions 50 are regions that suppress the progression of refractive errors of the eye. One or more adjacent island regions 50 on the lens element 10 have a shared edge.

[0110] As described above, through extensive research and practice, the inventors have found that one of the key factors that reduces the wearer's visual clarity in related technologies is the boundary between the island regions and the base region, i.e., the edge of the island regions. Because the base region and the island regions have different refractive powers, the edge of the island regions becomes the boundary between the two types of refractive powers. This boundary is a refractive power transition region, which does not have favorable optical properties and reduces the wearer's visual clarity. When the island regions on the lens are spaced apart and independent of each other, each island region on the lens has its own edge, resulting in an excessive refractive power transition region on the lens and reducing the wearer's visual clarity. The innovative lens element of the present invention solves the above problem. In the lens element of the present invention, one or more island regions and one or more adjacent island regions have a shared edge. In this way, the number of island regions is significantly reduced without reducing the number of island regions, improving the wearer's visual clarity.

[0111] Figure 5 shows a partially enlarged view of Figure 4, representing a partially enlarged representation of the island-shaped regions on the lens element. As shown in Figure 5, the partial region of the optical lens includes five island-shaped regions (50a, 50b, 50c, 50d, 50e) that share an edge. Island-shaped regions 50a and 50b have a shared edge ab, island-shaped regions 50a and 50e have a shared edge ae, island-shaped regions 50b and 50e have a shared edge be, island-shaped regions 50c and 50e have a shared edge ce, island-shaped regions 50c and 50d have a shared edge cd, and island-shaped regions 50d and 50e have a shared edge de. By sharing an edge, these five island-shaped regions (50a, 50b, 50c, 50d, 50e) significantly reduce the total perimeter of the edge.

[0112] In some embodiments, for adjacent first and second island-shaped regions having a shared edge, the total perimeter of the edge is significantly reduced by sharing the edge. The so-called shared edge is the edge of both the first and second island-shaped regions. Assuming that a 3mm long edge in the first island-shaped region is a shared edge and a 7mm long edge is a non-shared edge, and that a 3mm long edge in the second island-shaped region is a shared edge and a 7mm long edge is a non-shared edge, the total edge length of the first and second island-shaped regions is 7mm + 7mm + 3mm = 17mm. In the total length calculation, the 3mm long edge is added only once because it is shared by both the first and second island-shaped regions. The total perimeter of the edges of adjacent first and second island-shaped regions having a shared edge is reduced compared to the case where the first and second island-shaped regions are spaced apart.

[0113] In some embodiments, there is no base region between adjacent island-like regions having a shared edge.

[0114] Figure 6 shows an abstract schematic diagram of a longitudinal section (longitudinal section AA' in Figure 5) of a lens element according to one embodiment of the present invention. As shown in the figure, in some embodiments, the lens element 10 has a base region 55 and adjacent island regions (50a, 50b), and the adjacent island regions (50a, 50b) have a shared edge (ab). The island regions (50a, 50b) having a shared edge are fused with each other at the shared edge (ab). Parts of island region 50a and island region 50b are fused with each other to form a fused region 505. The island regions (50a, 50b) having a shared edge can be manufactured by methods known in the art (e.g., 3D printing, mold casting, machining, etc.).

[0115] As shown in Figure 6, in some embodiments, each island-like region (50a, 50b) has independent optical centers (40a, 40b). Independent optical centers (40a, 40b) are defined as optical centers that are spaced apart from each other, with the distance between them being greater than zero.

[0116] In some embodiments, the optical center may be defined as the intersection of the optical axis and the refractive plane.

[0117] In some embodiments, for a toric lens, the optical center may be defined as the vertex of the toric surface. For example, for a convex surface, the optical center is the highest point of the convex surface. For example, for a concave surface, the optical center is the lowest point of the concave surface.

[0118] As shown in Figure 5, in some embodiments, the lens element includes an island region array 500, the island region array 500 includes a plurality of continuously arranged island regions (50a, 50b, 50c, 50d, 50e), and adjacent island regions (50a, 50b) have a shared edge (ab).

[0119] As shown in Figure 5, in some embodiments, the island region array 500 is tiled with multiple island regions (50a, 50b, 50c, 50d, 50e). In this configuration, adjacent island regions within the island region array share edges sufficiently, significantly reducing the total edge length and improving the optical quality of the lens element.

[0120] As shown in Figure 4, in some embodiments, a plurality of island-shaped region arrays 500 are provided on the lens element, and the plurality of island-shaped region arrays 500 are distributed at intervals from each other. With this configuration, by rationally arranging the positions of the plurality of island-shaped region arrays 500 and the base region 55, a lens element with improved optical quality can be obtained, which suppresses the progression of refractive errors in the eye and provides the wearer with good visual clarity.

[0121] As shown in Figure 4, in some embodiments, the island-shaped region array 500 has a strip-like shape, and multiple island-shaped region arrays 500 are distributed parallel to each other and spaced apart. In this configuration, multiple island-shaped region arrays 500 can form stripes distributed parallel to each other on the lens element, and such a pattern is advantageous in providing good visual clarity to the wearer.

[0122] As shown in Figure 4, in some embodiments, the island region array 500 has a linear stripe shape, and multiple island region arrays 500 are distributed parallel to each other and spaced apart. In this configuration, multiple island region arrays 500 can form linear stripes distributed parallel to each other on the lens element, and such a pattern is advantageous in providing good visual clarity to the wearer.

[0123] Figures 7(A) and 7(B) show schematic plan views and longitudinal cross-sectional views (AA' cross-section) of lens elements according to several embodiments of this application, respectively. As shown in Figure 7, in some embodiments, the shape of the projection of the island-shaped region 50 onto the lens element surface is strip-shaped. The width of the strip-shaped island-shaped region 50 is, for example, 0.5 to 2 mm or 1 to 1.5 mm. Multiple strip-shaped island-shaped regions 50 are arranged in parallel, and adjacent island-shaped regions 50 have a shared edge, which is the long side edge of the strip-shaped island-shaped region.

[0124] In some embodiments, the band-shaped island region 50 may be a prismatic lens or a prismatic composite lens.

[0125] Figure 8 shows an abstract schematic diagram of a lens element according to several embodiments of this application.

[0126] As shown in Figure 8(a), in some embodiments, the lens element has a first side surface 11 and a second side surface 12 facing the first side surface 11, one or more island-like regions 50a are located on the first side surface 11 of the lens element, and the refractive surfaces of the island-like regions 50a are formed in a convex shape toward the object side with respect to the surface shape of the base region.

[0127] As shown in Figure 8(b), in some embodiments, the lens element has a first side surface 11 and a second side surface 12 facing the first side surface 11, one or more island-like regions 50b are located on the first side surface 11 of the lens element, and the refractive surfaces of the island-like regions 50b are formed in a concave shape toward the object side with respect to the surface shape of the base region.

[0128] As shown in Figure 8(c), in some embodiments, the lens element has a first side surface 11 and a second side surface 12 facing the first side surface 11, and one or more island-like regions 50c are located between the first side surface 11 and the second side surface 12 of the lens element. The island-like regions 50c are manufactured from a different material than the base region so as to have a different refractive power from the base region.

[0129] As shown in Figure 8(d), in some embodiments, the lens element has a first side surface 11 and a second side surface 12 facing the first side surface 11, one or more island-like regions 50d are located on the second side surface 12 of the lens element, and the refractive surfaces of the island-like regions 50d are formed in a convex shape toward the object side with respect to the surface shape of the base region.

[0130] As shown in Figure 8(e), in some embodiments, the lens element has a first side surface 11 and a second side surface 12 facing the first side surface 11, one or more island-like regions 50e are located on the first side surface 12 of the lens element, and the refractive surfaces of the island-like regions 50e are formed in a concave shape toward the object side with respect to the surface shape of the base region.

[0131] In some embodiments, the base region and the island region each have a refractive surface, and by making the shape of the refractive surface of the island region different from the shape of the refractive surface of the base region, the refractive force of the island region and the refractive force of the base region are made different.

[0132] In some embodiments, the base region and the island regions each have refractive surfaces, and the refractive surfaces of one or more island regions are formed in a convex shape toward the object side with respect to the surface shape of the base region.

[0133] In some embodiments, the base region and the island regions each have refractive surfaces, and the refractive surfaces of one or more island regions are formed in a concave shape toward the object side with respect to the surface shape of the base region.

[0134] In some embodiments, the island-like regions are manufactured from a different material than the base region, thereby giving the island-like regions a different refractive power than the base region. For example, the base region may be made from a material with a first refractive index, and the island-like regions from a material with a second refractive index.

[0135] In some embodiments, a portion of the island-like region is manufactured from a material different from the material constituting the base region. That is, the high-refractive-index material portion, which has a large refractive index, is provided in the island-like region in a substantially plano-convex shape, extending inward from the surface of the island-like region in the thickness direction. Even with such a structure, the same functionality as the island-like region in the embodiments described above can be obtained. In this case, for example, a plastic material as CR39 material can be used as the material for constituting the base region, and the CR39 material is manufactured from a thermosetting allyl resin with a refractive index of 1.5. For example, a plastic material manufactured from a thermosetting polythiourethane resin with a refractive index of 1.67 can be used as the high-refractive-index material to manufacture the island-like region.

[0136] As shown in Figure 4, in some embodiments, one or more island-like regions are formed near the center of the lens element. The center of the lens element is, for example, the optical center of the lens element. The center of the lens element is, for example, the geometric center of the lens element. The center of the lens element is, for example, the centroid of the lens element. The term “neighbor” may be understood as a region within a range of 20 mm away from the center, a region selectively within a range of 15 mm away from the center, a region further selectively within a range of 10 mm away from the center, and a region further selectively within a range of 5 mm away from the center.

[0137] In some embodiments, the lens element is a lens element having refractive power that suppresses the progression of myopia, and the island-shaped region has refractive power obtained by adding a positive refractive power to the first refractive power.

[0138] In some embodiments, the lens element is a lens element having refractive power that suppresses the progression of hyperopia, and the island-shaped region has refractive power obtained by adding a negative refractive power to the first refractive power.

[0139] As shown in Figures 5-7, in some embodiments, the shape of the projection of one or more island-like regions on one side surface of the lens element is circular, approximately circular, polygonal or approximately polygonal, or strip-shaped.

[0140] Figure 15 shows schematic diagrams of lens elements according to several embodiments of this application. As shown in the figure, island-shaped regions with different projection shapes are provided on the lens element. For example, a polygonal island-shaped region 506 is provided on the lens element. Also, for example, strip-shaped island-shaped regions (507a, 507b) are provided on the lens element.

[0171] In some embodiments, in a single lens element, the island-shaped region and the base region do not overlap with each other.

[0175] In some embodiments, the lens element is a contact-type spectacle lens, i.e., a spectacle lens that comes into contact with the wearer's cornea when worn.

[0176] In some embodiments, the first refractive power is between -10.00D and 10.00D, for example, between -10.00D and 0D, for example, between 0D and 10.00D.

[0177] In some embodiments, the first refractive power is -10.00D to -9.00D, -9.00D to -8.00D, -8.00D to -7.00D, -7.00D to -6.00D, -6.00D to -5.00D, -5.00D to -4.00D, -4.00D to -3.00D, -3.00D to -2.00D, and -2.00D to -1. The ranges are 00D, -1.00D to 0.00D, 0.00D to 1.00D, 1.00D to 2.00D, 2.00D to 3.00D, 3.00D to 4.00D, 4.00D to 5.00D, 5.00D to 6.00D, 6.00D to 7.00D, 7.00D to 8.00D, 8.00D to 9.00D, and 9.00D to 10.00D.

[0178] In some embodiments, the second refractive power is -10.00D to -9.00D, -9.00D to -8.00D, -8.00D to -7.00D, -7.00D to -6.00D, -6.00D to -5.00D, -5.00D to -4.00D, -4.00D to -3.00D, -3.00D to -2.00D, and -2.00D to -1. The ranges are 00D, -1.00D to 0.00D, 0.00D to 1.00D, 1.00D to 2.00D, 2.00D to 3.00D, 3.00D to 4.00D, 4.00D to 5.00D, 5.00D to 6.00D, 6.00D to 7.00D, 7.00D to 8.00D, 8.00D to 9.00D, and 9.00D to 10.00D.

[0179] In some embodiments, the difference between the second refractive power and the first refractive power is -10.00D to -9.00D, -9.00D to -8.00D, -8.00D to -7.00D, -7.00D to -6.00D, -6.00D to -5.00D, -5.00D to -4.00D, -4.00D to -3.00D, -3.00D to -2.00D, and -2.00D.

[0180] In some embodiments, the base region has substantially consistent refractive power, i.e., the refractive power does not substantially change with changes in the position of the base region surface.

[0181] In some embodiments, the base region has a refractive power that changes gradually with the position of the base region surface, meaning that the absolute value of the rate of change of refractive power in any direction of the lens element surface is greater than 0.00 D / mm and less than 5.00 D / mm, for example, from 0.5 D / mm to 1.00 D / mm, from 1.00 D / mm to 2.00 D / mm, from 2.00 D / mm to 3.00 D / mm, from 3.00 D / mm to 4.00 D / mm, and from 4.00 D / mm to 4.50 D / mm. In some embodiments, the base region has a continuously changing refractive power (a refractive power added so as to gradually become positive or a refractive power subtracted so as to gradually become negative) in the direction from the center to the edge of the lens element.

[0182] Figure 16 shows a lens element according to several other embodiments of the present invention. As shown in the figure, the lens element includes a base region 55 and a plurality of island-like regions 50. The base region 55 includes a prescription region 551 and a non-prescription region 552. The prescription region 551 has a prescription refractive power that corrects refractive errors of the eye. The non-prescription region 552 has a refractive power that is positive or negative compared to the prescription refractive power.

[0183] In some embodiments, the central region of the lens element may be used to form a prescription region 551. The prescription region has the function of correcting refractive errors of the eye.

[0184] In some embodiments, the outer peripheral region of the lens element may be used to form a non-prescription region, which may have refractive power other than that which corrects refractive errors of the eye, such as a more positive refractive power or a more negative refractive power. The non-prescription refractive region is, for example, a thinning region that thins the edge of the lens and improves the appearance of the lens. The non-prescription region may also include a defocus region that has the function of suppressing the progression of refractive errors.

[0185] In some embodiments, the multiple island-like regions 50 are located between the formulation region 551 and the non-formulation region 552.

[0186] In some embodiments, the island-like region is further defined as a region having a dimension of 3 mm or less in at least one direction.

[0187] In some embodiments, regions having dimensions of 3 mm × 3 mm or more in at least one pair of mutually perpendicular directions are not island-like regions.

[0188] In some embodiments, the dimensions of an island-like region are measured based on the boundary (edge) between the island-like region and an adjacent region.

[0189] In some embodiments, the boundary (edge) between an island-like region and an adjacent base region or island-like region is formed by a sudden change in refractive power.

[0190] In some embodiments, the island-like regions are configured such that there is a sudden change in refractive power between them and adjacent base regions or island-like regions.

[0191] In some embodiments, a sudden change in refractive power means that the absolute value of the rate of change of refractive power in any direction on the surface of the lens element reaches 5.00 D / mm or more.

[0192] In some embodiments, the sudden change in refractive power is, for example, from 5.00 D / mm to 6.00 D / mm, from 6.00 D / mm to 7.00 D / mm, from 7.00 D / mm to 8.00 D / mm, from 8.00 D / mm to 9.00 D / mm, or from 9.00 D / mm to 10.00 D / mm. For example, the change in refractive power at a distance of 0.2 mm reaches 1.00 D or more. Furthermore, for example, the change in refractive power at a distance of 0.5 mm reaches 2.50 D or more.

[0193] Figure 9 shows an abstract schematic diagram of eyeglasses according to several embodiments of the present invention. As shown in the figure, the present application provides eyeglasses including an eyeglass frame 30 and a lens element 90 attached to the eyeglass frame 30, wherein the lens element 90 is the lens element described in any one of the above claims.

[0194] As shown in Figure 9, in some embodiments, the eyeglasses include an eyeglass frame 30 and a first lens element 100 and a second lens element 200 mounted on the eyeglass frame 30. The first lens element 100 includes a base region 55 and a plurality of linear island region arrays 501, which are arranged parallel to each other and spaced apart, and which are parallel to the connecting line AB of the optical centers of the first and second lens elements. The second lens element 200 includes a base region 55 and a plurality of linear island region arrays 502, which are arranged parallel to each other and spaced apart, and which are parallel to the connecting line AB of the optical centers of the first and second lens elements. Optical lenses based on the above embodiments can provide the wearer with a better visual sense. In daily life, horizontal lines are the most common and are in the best harmony with the wearer's visual sense. Especially when reading on a daily basis, the orientation of the characters is usually horizontal.

[0195] Figure 17 shows a schematic diagram of the mold of the present invention. As shown in the figure, the mold 21 has a mold cavity 22, and the shape of the mold cavity 22 is set to match the shape of the lens element described in any one of the above items. Matching here means that the lens element described in any one of the above items can be obtained by casting the lens element in the above mold.

[0196] Experimental data The advantages of the technical solution of this application will be further explained below in relation to specific experimental data. It should be noted that all drawings mentioned in the following embodiments are abstract schematics, merely illustrating the pattern of the island-like regions, and are not drawings in the strict sense. To facilitate the reader's understanding, these schematics are modified by operations such as enlargement, reduction, partial enhancement, and partial simplification of some of the structure of the lens element. Therefore, the specific dimensions and distribution parameters of the island-like regions of the lens element still conform to the textual descriptions and the specific definitions in Table 1.

[0197] Example 1 Figure 9 shows an abstract schematic diagram of eyeglasses, and Figure 10 shows an abstract schematic diagram of the first and second lens elements on the eyeglasses.

[0198] As shown in Figures 9 and 10, the eyeglasses include an eyeglass frame 30 and a first lens element 100 and a second lens element 200 mounted on the eyeglass frame 30. The first lens element 100 and the second lens element 200 are identical. The first lens element 100 and the second lens element 200 are circular in shape and have a diameter of 35 mm. The first lens element 100 and the second lens element 200 each include a base region 55 and a plurality of island-shaped region arrays 500.

[0199] Figure 11 shows an abstract schematic diagram of the distribution pattern of island regions on the lens element of Example 1. As shown in Figure 11, each island region array 500 has the shape of a linear band. Both ends of each island region array 500 extend to the two edges of the first lens element 100. Multiple linear band island region arrays 500 are arranged parallel to each other and spaced apart. The width of each island region array 500 is 3.25 mm, and the spacing distance between adjacent island region arrays 500 is 4 mm. Each island region array 500 is parallel to the connecting line AB of the optical centers of the first lens element and the second lens element. The area other than the island region arrays 500 is the base region 55.

[0200] The structure of the island region array 500 is shown in Figure 5, where multiple island regions (50a, 50b, 50c, 50d, 50e) are densely arranged on the island region array 500. Adjacent island regions share a common edge.

[0201] The base region 55 has a prescription refractive power (first refractive power) that corrects refractive errors of the eye, and this first refractive power is 0.00D. The island regions (50a, 50b, 50c, 50d, 50e) each have a refractive power (second refractive power) that suppresses the progression of refractive errors of the eye, and this second refractive power is 7.5D. This second refractive power suppresses the progression of refractive errors of the eye by focusing light at a location other than the retina.

[0202] For the parameters of the lens elements (where the first and second lens elements coincide), please refer to Table 1. These parameters include, for example, the number of island-like regions, the percentage of the total area of ​​island-like regions on the lens, and the area of ​​the base region on the lens in mm². 2 This includes the length L1 / mm of the shared edges in the island region, the length L2 / mm of the non-shared edges in the island region, the total length of the edges in the island region (L1+L2)mm, and the ratio of L1 to L2.

[0203] Example 2 Example 2 provides eyeglasses with a structure similar to that of Example 1. The difference between Example 2 and Example 1 lies in the distribution pattern of island-like regions on the lens element. In particular, the island-like regions in the island-like region array are more sparsely distributed, and there are fewer shared edges between the island-like regions. Please refer to Table 1 for the parameters of the lens element.

[0204] Example 3 Example 3 provides eyeglasses with a structure similar to that of Example 1. The difference between Example 3 and Example 1 lies in the shape and distribution pattern of the island-like regions on the lens element.

[0205] Figure 13 shows an abstract schematic diagram of the distribution of island-shaped regions on the lens element. As shown in the figure, the shape of the island-shaped regions (505a, 505b) in Example 3 is linear. The linear island-shaped regions (505a, 505b) extend from one end to the other of the lens element 10. The width of the linear island-shaped regions (505a, 505b) is 1 mm. The refractive surfaces of the linear island-shaped regions (505a, 505b) are formed as prismatic convex shapes facing the object side relative to the surface shape of the base region 55, and the generatrix direction of the prismatic surface is the longitudinal direction of the island-shaped regions (505a, 505b). The base region 55 has a prescription refractive power (first refractive power) that corrects refractive errors of the eye, and the first refractive power is 0.00 D. The island regions (505a and 505b) each possess a refractive power (second refractive power) that suppresses the progression of refractive errors in the eye. This second refractive power is +7.5D, and it suppresses the progression of refractive errors by focusing light at locations other than the retina of the eye.

[0206] As shown in Figure 13, a pair of adjacent island-like regions (505a, 505b) form an island-like region array 500. The adjacent island-like regions (505a, 505b) share a long edge.

[0207] FIG. 13 shows only one island region array 500, but actually, a plurality of island region arrays 500 are distributed on the first lens element and the second lens element of Example 3. These island region arrays 500 are arranged at equal intervals and parallel to each other. Each island region array 500 is parallel to the connecting line of the optical centers of the first lens element and the second lens element of the glasses. Refer to Table 1 for the parameters of the lens element.

[0208] Comparative Example 1 Comparative Example 1 provides glasses with the same structure as Example 1. The difference between Comparitive Example 1 and Example 1 lies in the structure of the island region array, particularly the distribution pattern of the island regions on the island region array.

[0209] In the island region array of Comparitive Example 1, a plurality of island regions are structurally distributed at intervals, and adjacent island regions do not have a shared edge. The diameter of the island region is 1.3 mm, and the distance between adjacent island regions is 0.53 mm. The distribution density of the island regions (the ratio of the area of the island regions to the total area) is 42.2%. The island regions are uniformly distributed on the entire surface of the lens. The region other than the island region is the base region.

[0210] Comparative Example 2 Comparative Example 2 provides glasses with the same structure as Example 1. The difference between Comparitive Example 2 and Example 1 lies in the structure of the island region array, particularly the distribution pattern of the island regions on the island region array.

[0211] As shown in FIG. 12, the island regions of Comparitive Example 2 are more sparsely distributed, and some adjacent island regions (50a, 50b) have a shared edge, but the ratio of the shared edge is significantly lower than the ratio of the non-shared edge. In other words, the ratio of the length L1 of the shared edge of the island region is lower, and the ratio of the length L2 of the non-shared edge of the island region is higher. The parameters of the lens element are shown in Table 1.

[0212] Comparative Example 3 Comparative Example 3 provides glasses with the same structure as Example 3. The difference between Comparative Example 3 and Example 3 lies in the structure of the island region array, particularly in the distribution pattern of the island regions on the island region array.

[0213] FIG. 14 shows an abstract schematic diagram of the distribution of island regions on the lens element. As shown in the figure, a plurality of island regions (505a, 505b) are distributed at intervals on the lens element of Comparative Example 3. Although FIG. 14 shows only a pair of island regions (505a, 505b), actually, a plurality of similar island regions (505a, 505b) are distributed on the first lens element and the second lens element of Comparative Example 3.

[0214] The base region 55 has a prescribed refractive power (first refractive power) for correcting the refractive error of the eye, and the first refractive power is 0.00D. Each of the island regions (505a, 505b) has a refractive power (second refractive power) for suppressing the progression of the refractive error of the eye, and the second refractive power is 7.5D. The second refractive power focuses at a position other than the retina of the eye to suppress the progression of the refractive error of the eye.

[0215] The shape of each island region (505a, 505b) is a straight strip shape. Adjacent island regions (505a, 505b) do not have a shared edge. The plurality of straight strip-shaped island regions (505a, 505b) are arranged at intervals parallel to each other. The width of the straight strip-shaped island region (505a, 505b) is 1 mm. The interval distance between adjacent straight strip-shaped island regions is 1 mm. The parameters of the lens element are shown in Table 1. Blank Example

[0216] Glasses in which an optical lens group including a first lens element and a second lens element is arranged are provided. The first lens element has only a base region, and the base region has a refractive power of 0. The second lens element has only a base region, and the base region has a refractive power of 0. Visual Acuity Test

[0217] The wearers wore the eyeglasses of Examples 1-3 and Comparative Examples 1-2, respectively, and underwent a visual acuity test at a distance of 5 meters from a visual acuity chart according to the GB / T11533-2011 standard, with the wearers instructed to look at the chart. The results are shown in Table 1 below. The wearers' uncorrected visual acuity was 5.3.

[0218] TIFF0007867303000001.tif128164

[0219] As can be seen from the table above, (1) The glasses in the blank example do not have island-shaped regions that focus on a location other than the retina of the eye to suppress the progression of refractive errors in the eye, and the wearer's visual acuity is not affected by the island-shaped regions, therefore the wearer wearing the glasses in the blank example has a visual acuity of 5.3.

[0220] (2) The eyeglasses of Comparative Examples 1 and 3 have island-like regions that focus on locations other than the retina of the eye to suppress the progression of refractive errors. The island-like regions are spaced apart from each other and independent of one another, and each island-like region has a complete edge. The proportion of non-shared edges is relatively high (0 ≤ L1 / L2 < 0.3), which affects the wearer's visual clarity. The wearer's visual acuity after wearing the eyeglasses of Comparative Examples 1 and 3 was only 5.0, indicating that the visual acuity value is not high.

[0221] (3) The eyeglasses of Examples 1-3 also have island-shaped regions that focus on locations other than the retina of the eye, thereby suppressing the progression of refractive errors. Because several island-shaped regions share edges, the proportion of non-shared edges on the lens elements of Examples 1-2 was significantly lower than that of Comparative Example 1, and the proportion of non-shared edges on the lens elements of Example 3 was significantly lower than that of Comparative Example 3, without a decrease in the number of island-shaped regions. The proportion of shared edges in the island-shaped regions of Examples 1-3 was relatively high (L1 / L2≧0.3), improving the wearer's visual clarity. The wearer's visual acuity after wearing the eyeglasses of Examples 1-2 was 5.2-5.3, which was a substantial improvement in vision compared to Comparative Examples 1 and 3 (visual acuity value 5.0).

[0222] (4) Although Comparative Example 2 has a shared island-like region edge, the ratio L1:L2 of the length of the shared edge to the length of the non-shared edge of the island-like region is too low, at only 0.24, and does not reach the threshold of 0.3. In this case, the wearer does not substantially perceive an improvement in visual clarity, and the wearer's visual acuity after wearing the glasses of Comparative Example 2 was 5.0, which is not substantially an improvement in vision compared to Comparative Example 1 (visual acuity value 5.0).

[0223] The results above demonstrate that the lens element of the present invention can suppress the progression of refractive errors in the eye and provide the wearer with good visual acuity and visual function.

[0232] Referring to FIGS. 18(a) to 18(c), in some embodiments, the present application provides an optical lens group including a first lens element 10 and a second lens element 20.

[0233] Referring to FIG. 18(a), the first lens element 10 includes a base region 55 having a base refractive power, and an island region 50 having a refractive power different from the base refractive power and having a function of focusing at a position other than the retina of the eye to suppress the progression of refractive error of the eye. A first Y optical region is provided near the optical center of the first lens element 10. The first Y optical region includes a first A region 101 and a first B region 102. A plurality of independent island regions 50 are distributed within the first A region 101. The first B region 102 is substantially composed of the base region 55, or a plurality of independent island regions 50 are distributed within the first B region 102, and the first B region 102 has a lower distribution density of the island regions 50 than the first A region 101.

[0234] Referring to FIG. 18(b), the second lens element 20 includes a base region 55 having a base refractive power, and an island region 50 having a refractive power different from the base refractive power and having a function of focusing at a position other than the retina of the eye to suppress the progression of refractive error of the eye. A second Y optical region is provided near the optical center of the second lens element 20. The second Y optical region includes a second A region 201 and a second B region 202. A plurality of independent island regions 50 are distributed within the second A region 201. The second B region 202 is substantially composed of the base region 55, or a plurality of independent island regions 50 are distributed within the second B region 202, and the second B region 202 has a lower distribution density of the island regions 50 than the second A region 201.

[0235] Referring to FIG. 18(c), when the first lens element 10 and the second lens element 20 are placed parallel to each other and coaxially, they are arranged such that there is at least one relative position that satisfies a specific relationship. The specific relationship is (1) the projection of the first A region 101 of the first lens element 10 onto the second lens element 20 at least partially overlaps the second B region 202 of the second lens element 20; (2) The projection of the second A region 201 of the second lens element 20 onto the first lens element 10 overlaps at least partially with the first B region 102 of the first lens element 10.

[0236] It should be explained that the coaxial arrangement of the first lens element 10 and the second lens element 20 described above does not represent the usage state of the first lens element 10 and the second lens element 20, but rather serves to demonstrate that a specific mutual correspondence exists between the optical characteristics of the first lens element 10 and the optical characteristics of the second lens element 20 due to this particular relationship. When the first lens element 10 and the second lens element 20 are placed parallel to each other and coaxially, this specific mutual correspondence is very clearly demonstrated.

[0237] When the first lens element 10 and the second lens element 20 are worn on the left and right eyes of a person, respectively, the beneficial effects of the optical lens group of the above embodiment are shown as follows.

[0238] (1) The first A region 101 of the first lens element 10 has the function of suppressing the progression of refractive errors in the left eye, but it reduces the visual clarity of that region by the left eye to some extent. However, the second B region 202 of the second lens element 20 has a lower distribution density of island-like regions 50 than the second A region 201, and the projection of the first A region 101 of the first lens element 10 onto the second lens element 20 overlaps with the second B region 202 of the second lens element 20 at least partially. Therefore, it can be estimated that the second B region 202, which has a positional relationship of at least partially overlapping with the first A region 101, has relatively high visual clarity. To put it simply, it can be understood that the region in which the visual clarity of the left eye is reduced is enhanced to some extent in the corresponding region of the right eye.

[0239] (2) The second A region 201 of the second lens element 20 has the function of suppressing the progression of refractive errors in the right eye, but it reduces the visual clarity of that region by the right eye to some extent. However, the first B region 102 of the first lens element 10 has a lower distribution density of island-like regions 50 than the first A region 101, and the projection of the second A region 201 of the second lens element 20 onto the first lens element 10 overlaps at least partially with the first B region 102 of the first lens element 10. Therefore, it can be estimated that the first B region 102, which has a positional relationship of at least partially overlapping with the second A region 201, has relatively high visual clarity. To put it simply, it can be understood that the region in which the visual clarity of the right eye is reduced is enhanced to some extent in the corresponding region of the left eye.

[0240] Based on the principles of vision generation, the observer's left and right eyes each see objects at different angles, and the world perceived by the brain is a mixture of both. Therefore, areas where the clarity of the left eye is reduced are compensated for by the right eye, and areas where the clarity of the right eye is reduced are compensated for by the left eye, resulting in a unique complementary relationship between the left and right eyes. Ultimately, the signals received by both eyes are integrated and fed back to the brain, allowing the brain to still obtain relatively clear and complete target information. Thus, the lens assembly of this application suppresses the progression of refractive errors in both eyes and leverages the brain's ability to comprehensively utilize the visual signals from both eyes, providing the wearer with relatively clear and complete target information.

[0241] In some embodiments, when looking forward, the line of sight passes through approximately the center of the lens element to view an object. As a result, the object is viewed by the light beam that has passed through multiple island-like regions dispersed within the base region and the light beam that has passed through the base region. Consequently, this lens element has the effect of visually perceiving the image of the object formed by the first refractive power and suppressing the progression of myopia by the image formed in front of the retina by the second refractive power.

[0242] In some embodiments, when the eyes move, the line of sight shifts away from the center and passes through the periphery. However, since the periphery is the region with refractive power based on the prescription (the region with first refractive power), objects can be seen very well, and the wearer experiences little discomfort even when the eyes move. Therefore, it can demonstrate the function of suppressing the progression of refractive errors in the eye, while ensuring sufficient visibility and good wearing comfort.

[0243] In some embodiments, the structure of the first / second lens element has the function of focusing the base region on the retina of the eye. However, when forming a lens element that suppresses the progression of myopia, for example, the island region is made of a material that has the function of focusing on a point in front of the retina of the eye. Therefore, when a patient views an object with the lens element that suppresses the progression of myopia, an image of the object is formed on the retina and also focused in front of the retina. In other words, this lens element has the effect of visually perceiving the image of the object formed by the first refractive power and suppressing the progression of myopia by the image obtained in front of the retina by refractive powers other than the first refractive power. In the case of hyperopia, it can be said that the same applies except that the island region focuses on the retina of the eye.

[0244] In some embodiments, multiple independent island-like regions mean that each of the multiple island-like regions has an independent optical center. Considering that the present invention belongs to the field of optics, the term "independent" should also be understood from an optical perspective, that is, it should be understood as having an independent optical center.

[0245] In some embodiments, in a plurality of independent island-like regions, some island-like regions and adjacent island-like regions share a common edge (i.e., they are connected to each other).

[0246] In some embodiments, in a plurality of independent island-like regions, some island-like regions and adjacent island-like regions do not share a common edge (i.e., they are spaced apart from each other).

[0252] In some embodiments, for all island-shaped regions on the lens element, the length of the shared edge portion is L1, the length of the non-shared edge portion is L2, and the ratio of L1 to L2 is 0.3 or greater.

[0253] In some embodiments, some or all of the edges of one or more island-like regions are shared edges.

The distribution density of island-like regions on the first B region 102 and the first A region 101 is both greater than zero, but the distribution density of island-like regions 50 on the first B region 102 is lower than that on the first A region 101, or This means that the distribution density of island-like regions on the first B region 102 is zero, and the distribution density of island-like regions on the first A region 101 is greater than zero.

[0269] In some embodiments, the difference between the refractive power of the island region and the refractive power of the base region is -10.00D to -9.00D, -9.00D to -8.00D, -8.00D to -7.00D, -7.00D to -6.00D, -6.00D to -5.00D, -5.00D to -4.00D, -4.00D to -3.00D, -3.00D to -2.00D, and -2.

[0271] In some embodiments, the base region has a refractive power that changes gradually with the position of the base region surface, meaning that the absolute value of the rate of change of refractive power in any direction of the lens element surface is greater than 0.00 D / mm and less than 5.00 D / mm, for example, from 0.5 D / mm to 1.00 D / mm, from 1.00 D / mm to 2.00 D / mm, from 2.00 D / mm to 3.00 D / mm, from 3.00 D / mm to 4.00 D / mm, and from 4.00 D / mm to 4.50 D / mm. In some embodiments, the base region has a continuously changing refractive power (a refractive power added so as to gradually become positive or a refractive power subtracted so as to gradually become negative) in the direction from the center to the edge of the lens element.

[0272] In one specific embodiment, the peripheral region of the base region has a more positive refractive power than the central region of the base region. In some embodiments, the peripheral region of the base region may be used to form a defocused region.

[0273] In some embodiments, the island-like regions are configured such that a sudden change in refractive power exists between them and adjacent base regions. This sudden change in refractive power constitutes the boundary between the island-like regions and the adjacent base regions.

[0274] In some embodiments, a sudden change in refractive power means that the absolute value of the rate of change of refractive power in any direction on the surface of the lens element reaches 5.00 D / mm or more.

For example, the change in refractive power at a distance of 0.2 mm reaches 1.00 D or more. Furthermore, for example, the change in refractive power at a distance of 0.5 mm reaches 2.50 D or more.

Comparative Example 1

[0354] The present invention provides eyeglasses in which an optical lens group, as shown in Figure 26, including a first lens element and a second lens element, is arranged.

[0355] The first lens element includes a base region 55 and an island region 50, with the base region 55 having a refractive power of 0.00D and the island region 50 having a refractive power of 3.50D. A hexagonal 7X optical region and an annular 7Z optical region are sequentially provided near the optical center of the first lens element. The 7X optical region is composed of the base region 55.

[0357] The present invention provides eyeglasses in which an optical lens group including a first lens element and a second lens element is arranged. The first lens element has only a base region 55, and the base region 55 has a refractive power of 0. The second lens element has only a base region 55, and the base region 55 has a refractive power of 0. Visual Clarity Test

[0358] The wearer will wear the eyeglasses of Example 1, Comparative Example 1, and the blank example, and will perform a visual acuity test at a distance of 5 meters from the visual acuity chart according to the GB / T11533-2011 standard, instructing the wearer to view the visual acuity chart through a specific area of ​​the lens element.

[0359] For the lens element in Example 1, the wearer is instructed to view the eye chart through the 1X, 1Y, and 1Z regions of the lens element, respectively.

[0360] For the lens element in Comparative Example 1, the wearer is instructed to view the eye chart through the 7X and 7Z regions of the respective lens element.

[0361] For the blank example lens element, since the entire lens element is the base area, the wearer is instructed to view the eye chart directly through the base area.

[0362] The results are as follows: TIFF0007867303000002.tif47156

[0363] As can be seen from the table above, (1) The glasses in the blank example do not have island-shaped regions that focus on a location other than the retina of the eye to suppress the progression of refractive errors in the eye, and the wearer's visual acuity is not affected by the island-shaped regions, therefore the wearer wearing the glasses in the blank example has a visual acuity of 5.3.

[0364] (2) The eyeglasses of Comparative Example 1 have a 7X / 9X optical region and a 7Z / 9Z optical region. The 7X / 9X optical region does not have an island-shaped region that focuses on a location other than the retina of the eye to suppress the progression of refractive errors, so the visual acuity when the wearer looks at the visual acuity chart through this region is 5.3. The 7Z / 9Z optical region has an island-shaped region that focuses on a location other than the retina of the eye to suppress the progression of refractive errors, and the visual acuity when the wearer looks at the visual acuity chart through this region is only 5.0, which is not a high visual acuity.

[0365] (3) The eyeglasses of Example 1 have a first X / 2X optical region, a first Y / 2Y optical region, and a first Z / 2Z optical region. The first X / 2X optical region does not have an island-shaped region that focuses on a location other than the retina of the eye to suppress the progression of refractive errors, so the visual acuity when the wearer looks at the visual acuity chart through this region is 5.3. The first Z / 2Z optical region has an island-shaped region that focuses on a location other than the retina of the eye to suppress the progression of refractive errors, and the visual acuity when the wearer looks at the visual acuity chart through this region is only 5.0. In the first Y / 2Y optical region, the first A region and the first B region corresponding to the first eye, and the second A region and the second B region corresponding to the second eye, have a binocular complementary structure unique to this application. Specifically, the area reduced by the first A region of the first eye is compensated for by the second B region of the second eye, and the area reduced by the first B region of the second eye is compensated for by the first A region of the first eye. The visual acuity of the wearer when viewing the eye chart through the first Y / 2Y optical region is high at 5.2. From this, it can be seen that this region can suppress the progression of refractive errors in the eye and also hardly impair the visual acuity value.

[0366] Furthermore, the inventors have found that the optical lens group of Embodiment 1 of this application shows results very close to the blank example in multiple visual function tests (particularly binocular vision function tests such as sensory fusion tests and motor fusion tests), which indicates that the optical lens group of this application can suppress the progression of refractive errors of the eye and also does not substantially impair the wearer's visual function.

[0367] The results above demonstrate that the optical lens group, lens element, and eyeglasses of this application can suppress the progression of refractive errors in the eye and provide the wearer with good visual acuity and visual function.

[0368] Finally, it should be noted that the above embodiments are merely for illustrating the technical solutions of the present invention and do not limit them. Although the present invention has been described in detail with reference to preferred embodiments, as those skilled in the art will understand, specific embodiments of the present invention can be modified or some of its technical features can be replaced with equivalent versions without departing from the spirit of the technical solutions of the present invention, and all such modifications fall within the scope of the technical solutions claimed in the present invention.
