Spectacle Glass and Spectacle Lens for Data Reflection
First Claim
1. A spectacle lens with 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 forms a major portion of the spectacle lens together with the opposite second surface of the spectacle lens, which major portion is designed for vision in at least one predetermined distance; and
the prism zone of the first surface forms a prism portion together with the opposite second surface of the spectacle lens, which prism portion is designed and arranged so as to form an optical image of a display in a predetermined virtual distance in front of the eyes of the spectacle wearer.

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.

31. A method for calculating or optimizing a spectacle lens, comprising a calculating or optimizing step of at least a first surface of the spectacle lens, wherein the calculating or optimizing step comprises
specifying a major portion zone and a prism zone of the first surface, and calculating or optimizing the first surface such that the first surface in the major portion zone forms a major portion of the spectacle lens together with an opposite second surface of the spectacle lens, which major portion is designed for vision in at least one predetermined distance; - and
the first surface in the prism zone forms a prism portion together with the opposite second surface of the spectacle lens, which prism portion is designed and arranged so as to form an optical image of a display in a predetermined virtual distance in front of the eyes of the spectacle wearer. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62)
