Abstract:
In an eyeglass lens, an edge adjustment between an incoupling segment and an outcoupling structure can be provided by shaping of the inner surface. In the region of the eyeglass lens through which the eye looks for straight-ahead viewing, the inner surface substantially has a curvature that approximates the curvature of a typical inner surface of an eyeglass lens to such an extent that no perceptible optical imaging errors are induced by the inner surface when straight-ahead viewing. In the region of the edge adjustment, the inner surface has a shape that deviates to a greater extent from the curvature of the typical inner surface, which shape enables an imaging beam path coupled into the eyeglass lens by the incoupling segment to be directed to the outcoupling structure by reflections between the inner surface and the outer surface of the eyeglass lens.

Claim (Index 21):
A spectacle lens for an imaging optical unit for generating a virtual image of an initial image represented on an image generator, comprising:\n an inner surface that faces an eye of the user; an outer surface that faced away from the eye of the user; an input coupling section for coupling an imaging beam path in between the inner surface and the outer surface; and an output coupling structure for coupling the imaging beam path out of the spectacle lens in the direction of the eye, wherein the input coupling section is arranged in the spectacle lens such that an imaging beam path, coupled into the spectacle lens through the input coupling section, is guided to the output coupling structure by way of reflections between the inner surface and the outer surface of the spectacle lens, wherein, situated between the input coupling section and the output coupling structure in the spectacle lens is a periphery adaptation that is implemented by a corresponding shaping of the inner surface, wherein in a region of the spectacle lens through which the eye looks when the user is looking straight ahead, the inner surface has substantially a curvature that is approximated to the curvature of a typical inner surface of a spectacle lens with or without correction of a refractive error to such an extent that it does not induce any optical aberrations that are perceivable when looking straight ahead, and, in the region of the periphery adaptation, the inner surface has a shaping that deviates more strongly from the curvature of the typical inner surface and makes possible the guidance of an imaging beam path, which has been coupled into the spectacle lens through the input coupling section, by way of reflections between the inner surface and the outer surface of the spectacle lens to the output coupling structure, and wherein an entirety of the inner surface of the spectacle lens is described by a single free-form surface.
