DESCRIPTION OF EXEMPLARY EMBODIMENTS

(13) Explanations were given above that the spectacle lens according to the disclosure comprises at least two volume element groups. The two volume element groups, referred to as first and second volume element groups below, each comprise a plurality of corresponding volume elements. The volume elements of the first volume element group are referred to as first volume elements below; the volume elements of the second volume element group are referred to as second volume elements below.

(14) The first volume elements are arranged as grid points of a geometric grid and form a first partial grid. The first volume elements are made of a first material with a first Abbe number v.sub.1. The second volume elements are likewise arranged as grid points of a geometric grid and together form a second partial grid in their own right. The second volume elements are made of a second material with a second Abbe number v.sub.2, which is different than the first Abbe number v.sub.1.

(15) The first partial grid and the second partial grid are arranged displaced within one another in penetrative fashion in each case. As a result, the regions of the spectacle lens that are defined by the two partial grids respectively formed from different volume elements geometrically coincide on a macroscopic level. This will be elucidated once again below with reference to the figures.

(16) FIG. 1 shows a first exemplary embodiment for the arrangement of two partial grids formed by volume elements of first and second volume element groups, displaced within one another in penetrative fashion. The first partial grid includes volume elements 1a, 1b, 1c . . . 1t, 1u, which are depicted as parallelepipedal in the present exemplary embodiment and which are arranged like the white fields of two checkerboards arranged one above the other. The second partial grid includes volume elements 2a, 2b, 2c . . . 2t, 2u, which are depicted as parallelepipedal in the present exemplary embodiment and which are arranged like the black fields of two checkerboards arranged one above the other. The colors of the fields of the lower checkerboard are interchanged relative to the colors of the upper checkerboard.

(17) In this exemplary embodiment, each volume element 1a, 1b, 1c . . . 1t, 1u, 2a, 2b, 2c . . . 2t, 2u takes up the same rectangular volume having edge lengths a.sub.1, a.sub.2, a.sub.3. The edge lengths a.sub.1, a.sub.2, a.sub.3 typically lie in the range between 10 μm and 1 mm. The volumes of the parallelepipedal volume elements 1a, 1b, 1c . . . 1t, 1u, 2a, 2b, 2c . . . 2t, 2u are then in the range between 1000 μm.sup.3 and 1 mm.sup.3.

(18) In the present exemplary embodiment, the first partial grid that is based on the volume elements 1a, 1b, 1c . . . 1t, 1u and the second partial grid that is based on the volume elements 2a, 2b, 2c . . . 2t, 2u have an identical exemplary embodiment. From a geometric point of view, the two partial grids are offset in relation to one another by the edge length a.sub.1 in the direction of a sheet row. Alternatively, it is also possible that the two partial grids are offset in relation to one another by the edge length a.sub.2 in a direction perpendicular to the direction of a sheet row. In this exemplary embodiment, both partial grids lie in one plane. In the present case, let the surface 3 visible in FIG. 1 be the surface facing the object in the case of an intended use of the spectacle lens, which is based on the structure shown in FIG. 1. Accordingly, the surface 4 that is not visible in FIG. 1 in that case is the surface facing the eye of the spectacle wearer in the case of an intended use of the spectacle lens. The object-side surface of a single volume element 1a, 1b, 1c . . . 1t, 1u, 2a, 2b, 2c . . . 2t, 2u, which in each case represents a plane surface in the present schematic exemplary embodiment, lies between 100 μm.sup.2 and 1 mm.sup.2, taking account of the aforementioned size specifications.

(19) From a macroscopic standpoint, the surface region defined by the first partial grid and the surface region defined by the second partial grid coincide, such that no macroscopic separation exists.

(20) By way of example, WO 2015/102938 A1 describes in detail how such grid structures can be produced. Thus, a 3D printer equipped with one or more processors receives a CAD model with data of, in the present exemplary embodiment, two layers, each by themselves comprising a multiplicity of volume elements. Thus, the data contain, for example, the information that the first volume elements 1a, 1b, 1c . . . 1t, 1u, specified above, are intended to be manufactured from a first material with a first Abbe number v.sub.1, corresponding to a first printing ink, and the information that the second volume elements 2a, 2b, 2c . . . 2t, 2u, specified above, should be manufactured from a second material with a second Abbe number v.sub.2, corresponding to a second printing ink. From the data, the processor or processors of the 3D printer calculate the respective location at which the respective printing ink is intended to be placed, the temperature and/or the UV light requirements and the corresponding times to cure the placed printing ink for the purposes of generating the respective volume element 1a, 1b, 1c . . . 1t, 1u, 2a, 2b, 2c . . . 2t, 2u. In the present exemplary embodiment, the first material shall be PC, and the second material PMMA. The two substances mentioned are thermoplastics, the curing of which does not require UV light.

(21) FIG. 2 shows a further exemplary embodiment of an arrangement of volume elements of partial grids, displaced within one another in penetrative fashion. In this exemplary embodiment, the overall grid is formed from four partial grids. The four partial grids comprise volume elements of first, second, third, and fourth volume element groups. The first partial grid, which is based on the hexagonal volume elements 11a, 11b, 11c, 11d, the second partial grid, which is based on the hexagonal volume elements 12a, 12b, 12c, 12d, the third partial grid, which is based on the hexagonal volume elements 13a, 13b, and the fourth partial grid, which is based on the hexagonal volume elements 14a, 14b, have an identical embodiment in the present exemplary embodiment. The volumes of the hexagonal volume elements 11a, 11b, 11c, 11d, 12a, 12b, 12c, 12d, 13a, 13b, 14a, 14b are in the range of between 1000 μm.sup.3 and 1 mm.sup.3. In the present case, let the surface 3 visible in FIG. 2 be the surface facing the object in the case of an intended use of the spectacle lens, which is based on the structure shown in FIG. 2. Accordingly, the surface 4 that is not visible in FIG. 2 in that case is the surface facing the eye of the spectacle wearer in the case of an intended use of the spectacle lens. In the present exemplary embodiment, the first material shall be PET, the second material PMMA, the third material PC, and the fourth material PU.

(22) From a macroscopic standpoint, the surface region defined by the first partial grid, the surface region defined by the second partial grid, the surface region defined by the third partial grid and the surface region defined by the fourth partial grid coincide, such that no macroscopic separation exists.

(23) FIG. 3 shows a second exemplary embodiment for the arrangement of two partial grids formed by volume elements of first and second volume element groups, displaced within one another in penetrative fashion. The first partial grid is based on the ring-segment-shaped volume elements 21a, 21b, 21c, . . . , which are depicted with hatching in FIG. 3. The second partial grid comprises a plurality of ring-segment-shaped volume elements 22a, 22b, 22c, . . . , which are depicted white in FIG. 3.

(24) FIG. 4 shows a third exemplary embodiment for the arrangement of two partial grids formed by volume elements of first and second volume element groups, displaced within one another in penetrative fashion.

(25) In the present exemplary embodiment, the first partial grid that is based on the volume elements 1a, 1b, 1c . . . 1x, 1y, 1z and the second partial grid that is based on the volume elements 2a, 2b, 2c . . . 2x, 2y, 2z have an identical embodiment. Both partial grids represent a sequence of three-dimensional structures illustrated as cubic, the respective volume elements 1a, 1b, 1c . . . 1x, 1y, 1z, 2a, 2b, 2c . . . 2x, 2y, 2z of which are arranged adjacently and in a manner interleaved in one another. Accordingly, the final grid comprises three layers of the type described with reference to FIG. 1. In the present case, let the surface 3 visible in FIG. 4 be the surface facing the object in the case of an intended use of the spectacle lens, which is based on the structure shown in FIG. 4. Accordingly, the surface 4 that is not visible in FIG. 4 in that case is the surface facing the eye of the spectacle wearer in the case of an intended use of the spectacle lens.

(26) FIGS. 5A to 5C show a fourth exemplary embodiment for the arrangement of two partial grids formed by volume elements of first and second volume element groups, displaced within one another in penetrative fashion. FIG. 5A shows the basic arrangement of the volume elements 51a, 51b, . . . 51t, 51u, 52a, 52b, 52c, . . . 52t, 52u in the style of a three-dimensional two-layered checkerboard pattern, as described in detail above in relation to FIG. 1. In the present case, let the surface 3 visible in FIG. 5A be the surface facing the object in the case of an intended use of the spectacle lens, which is based on the structure shown in FIG. 5A. Accordingly, the surface 4 that is not visible in FIG. 5A in that case is the surface facing the eye of the spectacle wearer in the case of an intended use of the spectacle lens. It shall furthermore be assumed that the surface 3 shows a segment of the actual front surface of the spectacle lens and the surface 4 represents the corresponding opposite segment of the actual back surface of the spectacle lens.

(27) A light ray coming from an object will for example enter the spectacle lens on the surface of the first volume element 51a facing the object, pass through the volume element 51a, emerge again at the rear side thereof, in this case enter the volume element 52i through the front surface thereof, pass through the volume element and emerge at the rear side thereof in order to leave the spectacle lens again on the rear side and from there enter the eye of the spectacle wearer. According to the disclosure, the two volume elements 51a and 52i are intended to be able to interact in achromatic fashion. FIGS. 5B and 5C show two advantageous configurations for the volume elements 51a and 52i for achieving this purpose.

(28) It has been explained above that for an achromatic (or, if appropriate, apochromatic) interaction, for example, a plurality of dispersive optical first and second volume elements, the form of which is coordinated with one another, can be arranged in succession in the light path in such a way that the color dispersion of the first volume element (or of the plurality of first volume elements) is cancelled out again by that of the second volume element (or of the plurality of second volume elements), without the deflection itself being cancelled. By way of example, it is indicated that they can be embodied as prism elements or as lens elements.

(29) FIG. 5B shows the configuration of the volume elements 51a and 52i in the form of lens elements. The first volume element 51a is embodied as a micro-convex lens element according to this exemplary embodiment and the second volume element 52i is embodied as a micro-concave lens element according to this exemplary embodiment. The focal lengths and Abbe numbers of the two lens elements 51a, 52i must ideally be coordinated with one another such that the achromatism condition (e.g., in accordance with the approximation formula above) is satisfied in the best possible way.

(30) FIG. 5C shows the configuration of the volume elements 51a and 52i in the form of prism elements. The first volume element 51a is embodied as a prism element having the base position B1 according to this exemplary embodiment and the second volume element 52i is embodied as a prism element having the base position B2 according to this exemplary embodiment. The base positions and prism powers of the two prism elements 51a, 52i must ideally be coordinated with one another such that the achromatism condition is satisfied in the best possible way. The base positions B1, B2 of the two prism elements 51a, 52i are arranged opposite one another.

(31) FIG. 6 shows a first exemplary embodiment of a spectacle lens 60 in a plan view from the object side in the form of a schematic sketch. The visible surface is denoted by the reference sign 63. The exemplary embodiment has a region 61, which is embodied in the form according to the disclosure.
