Claim 10:
11. A system for determining at least one optical parameter of at least one spectacle lens, the system comprising:
at least one camera, wherein the at least one camera is configured to capture at least one image picturing the at least one spectacle lens and to generate at least one signal related to a position of a focus of the at least one camera;
at least one evaluation unit, wherein the at least one evaluation unit is configured to determine 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 evaluation unit is further configured to determine the at least one optical parameter of the at least one spectacle lens 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.
