Abstract
A computer-implemented method of determining a base curve value representing a base curve for a front surface of a spectacle lens is disclosed. The method includes receiving individual prescription data and determining the base curve value for the front surface of the spectacle lens based on the prescription data. In particular, the base curve value is calculated from the received prescription data based on a functional relationship between one or more values included in the prescription data and the base curve value.
