The invention relates to a spectacle lens for a display device (1) which can be placed on the head of a user and which generates an image, comprising a front face (5) and a rear face (6), said front face (5) and/or the rear face (6) being curved, and comprising an in-coupling portion (10) in an edge region (15) of the spectacle lens (3, 4) and an out-coupling portion (11) in a central region (16) of the spectacle lens (3, 4), when seen in plan view of the spectacle lens (3, 4). The spectacle lens (3, 4) is suitable for coupling light bundles (L1, L2, L3) of pixels of the generated image into the spectacle lens (3, 4) via the in-coupling portion (10), for guiding the light bundles in the spectacle lens (3, 4) to the out-coupling portion (11), and for coupling the light bundles out of the spectacle lens (3, 4) via the out-coupling portion (11). At least one of the light bundles (L1) is divided into respective multiple first sub-bundles (L11, L12, L13, L14) and coupled into the spectacle lens (3, 4) in a first direction in an offset manner relative to one another when being in-coupled via the in-coupling portion (10) such that the first sub-bundles (L11-L14) are guided to the out-coupling portion (11) in the spectacle lens (3, 4) along a second direction, which runs transverse to the first direction, and at least one of the first sub-bundles (L11) is divided into respective multiple second sub-bundles (L111, L112, L113, L114) and coupled out of the spectacle lens in the second direction in an offset manner relative to one another when being out-coupled via the out coupling portion (11). |
