The invention relates to an eyeglass lens for a display device (1), which display device can be placed on the head of a user and produces an image, wherein the eyeglass lens (3) has a front side (18) and a back side (15), an incoupling segment (11) and an outcoupling segment (13) spaced apart from the incoupling segment (11), and a light-conducting channel (12), which is suitable for conducting light bundles (9) of pixels of the produced image, which are coupled into the eyeglass lens (3) via the incoupling segment (11) of the eyeglass lens (3), in the eyeglass lens (3) to the outcoupling segment (13), by means of which the light bundles are coupled out of the eyeglass lens (3), wherein the eyeglass lens (3) has a multi-shell construction and comprises an outer shell (19) and an inner shell (22) connected to the outer shell (19), wherein the first side (20) of the outer shell (19) facing away from the inner shell (22) forms the front side (18) of the eyeglass lens (3) and the first side (23) of the inner shell (22) facing away from the outer shell (19) forms the back side (15) of the eyeglass lens (3), wherein the outer shell (19) comprises the incoupling segment (11), the light-conducting channel (12), and the outcoupling segment (13), and the inner shell (22) comprises a recess (27), which extends toward the back side (15) from the second side (24) of the inner shell (22) facing the outer shell (19) and in which the light-conducting channel (12) sits, wherein the outcoupling segment (13) lies adjacent to the recess (27) such that the light bundles (9) coupled out by means of the outcoupling segment (13) enter the inner shell (22) via the second side (24) of the inner shell (22), pass through the inner shell (22), and leave the inner shell (22) via the back side (15). |
