    摘要: A family of spectacle lenses is provided in which each spectacle lens is configured to achieve a specified prescriptive spherical power from among a number of prescriptive spherical powers and a specified prescriptive astigmatic power from among a number of prescriptive astigmatic powers. Each spectacle lens has a specified rotationally symmetrical spectacle-lens front face, a specified atoric spectacle-lens rear face, and in at least one principal section, such a deviation in the curvature from the circular form that, for a value for the distance between the vertex of the spectacle lens rear face and the pivot point of the eye, which lies in a range between 15 and 40 mm, at any point in a spectacle lens region within a radius of 25 mm about the geometrical center of the spectacle lens, an upper limit of the total deviation of the power is not exceeded.
