Abstract
A spectacle lens for smartglasses can include at least one light source arrangement at the edge of the spectacle lens that emits coherent light, or at least one region at the edge of the spectacle lens for coupling in light from a light source arrangement that emits coherent light, or at least one light source arrangement that is embedded in the spectacle lens. A transparent or partly transparent display can provided to the spectacle lens such that coherent light emanating from the light source arrangement emits coherent light passing through the display or is reflected by the display. The wavefront of the coherent light is modulable in terms of its amplitude and/or its phase by an actuation of the display. A deformation device for deforming the wavefront of the coherent light before or after the modulation by the display can also be provided.
