Abstract
An eyeglass lens for an optical imaging element for producing a virtual image of an initial image includes a main body and at least one complementary element mounted on the main body. The main body has a material with a first index of refraction n. A viscous or solid intermediate layer is arranged between the complementary element and the main body at least in the region where the complementary element overlaps with a reflection section of the main body. The material of the viscous or solid intermediate layer has a second index of refraction nthat satisfies the condition n<nsin(θ). θis an angle of incidence of the light beams of the imaging beam path proceeding from the incoupling section and incident on the reflection section, selected such that at least 50% of the light beams of the imaging beam path have an angle of incidence of θ>θ.
