Abstract

The invention relates particularly to a spectacle lens having a first and a second surface, wherein at least the first surface of the spectacle lens has a major portion zone and at least one prism zone. The major portion zone of the first surface, together with the opposing second surface of the spectacle lens, forms a major portion of the spectacle lens, which is designed for vision in at least a predetermined distance. The prism zone of the first surface, together with the opposing second surface of the spectacle lens, forms a prism portion, which is designed and arranged such that an optical image of a display is formed at a predetermined virtual distance in front of the eyes of the spectacle wearer. The invention further relates to spectacles, which comprise the spectacle lens, and to a method and apparatuses for calculating or optimizing and producing the spectacle lens.
