1. A method for applying a first optical mark to a first spectacle lens and a second optical mark to a second spectacle lens mounted in a spectacle frame, the method comprising:
capturing an image of at least such parts of the spectacle frame enclosing the first spectacle lens and the second spectacle lens mounted in the spectacle frame with an image capturing unit;
determining an intended position of the first optical mark at the first spectacle lens based on the spectacle frame including evaluating the image captured by the image capturing unit;
arranging the spectacle frame in a marking device having a marking appliance and adjusting a relative position of the spectacle frame and the marking appliance such that an actuation axis of the marking appliance intersects with the first spectacle lens at the intended position of the first optical mark;
applying the first optical mark to the spectacle lens at the intended position by using the marking appliance;
determining one or more of the following parameters: a center axis of the spectacle frame and a center point of the spectacle frame;
applying the second optical mark to the second spectacle lens mounted in the spectacle frame, wherein applying the second optical mark to the second spectacle lens mounted in the spectacle frame includes:
determining an intended position of the second optical mark at the second spectacle lens based on the position of the first optical mark at the first spectacle lens and based on at least one of the center axis of the spectacle frame and the center point of the spectacle frame;
adjusting the relative position of the spectacle frame and the marking appliance such that an actuation axis of the marking appliance intersects with the second spectacle lens at the intended position of the second optical mark; and
applying the second optical mark to the second spectacle lens at the intended position of the second optical mark with the marking appliance.
