Abstract

In a method for creating a design of a prescription surface of a multifocal lens, in particular for a progressive spectacle lens, at first data and second data for describing at least one aberration of an eye of a proband for a first situation of use and a second situation of use, respectively, are obtained, and then a first set of parameters and a second set of parameters of a predetermined prescription surface equation are determined from the first and second data, wherein the prescription surface equation is assigned to a first reference point of the prescription surface for the first set of parameters, and is assigned to a second reference point of the prescription surface for the second set of parameters.
