Zusammenfassung:	Provided is 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 comprises determining an intended position of the first optical mark at the first spectacle lens in an automated manner based on the spectacle frame including taking an image of at least a part of the spectacle frame. The method further comprises arranging the spectacle frame in a marking device having a marking appliance and adjusting the 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. In addition, the method comprises applying the first optical mark to the spectacle lens at the intended position by using the marking appliance. The method further comprises applying the second optical mark to a second spectacle lens mounted in the spectacle frame, wherein applying the second optical mark to the second spectacle lens mounted in the spectacle frame comprises taking an image of at least a part of the first spectacle lens including the intended and/or actual position of the first optical mark at the first spectacle lens and of at least a part of the spectacle frame surrounding the first spectacle lens. Applying the second optical mark further comprises determining an intended position of the second optical mark at the second spectacle lens in an automated manner using the image of at least a part of the first spectacle lens including the intended and/or actual position of the first optical mark at the first spectacle lens and of at least a part of the spectacle frame surrounding the first spectacle lens, 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 by using the marking appliance. Determining the intended position of the optical mark based on the spectacle frame includes determining one or more of the following parameters based on the image: a box dimension of the spectacle frame enclosing the mounted spectacle lens; a center point of the spectacle lens mounted in the spectacle frame.
