1. A method for determining at least one optical parameter of at least one spectacle lens, the method comprising the following steps:
a) capturing at least one image picturing the at least one spectacle lens by using at least one camera, wherein the at least one camera generates at least one signal related to a position of a focus of the at least one camera; and
b) determining at least one optical parameter of the at least one spectacle lens by processing the at least one image and by using the at least one signal related to the position of the focus of the at least one camera,
wherein the at least one optical parameter of the at least one spectacle lens is determined by comparing the at least one signal related to the position of the focus of the at least one camera to at least one further signal related to a further position of the focus of the at least one camera in at least one further image not picturing the at least one spectacle lens.
