Zusammenfassung:	The present invention relates to a method (164), a computer program product and a system (110) for determining at least one optical parameter (172) of at least one spectacle lens (114) and to a related method (160) for producing the at least one spectacle lens (114) by adjusting the at least one optical parameter (172). Herein, the method (164) for determining the at least one optical parameter (172) of the at least one spectacle lens (114) comprises the following steps:a) capturing at least one image (124) picturing the at least one spectacle lens (114) by using at least one camera (120), wherein the at least one camera (120) generates at least one signal (168) related to a position of a focus, wherein the at least one focus of the camera (120) is adjusted to at least one object (130) in space in at least one first distance to the at least one spectacle lens (114) and in at least one second distance to the at least one camera (120); andb) determining at least one optical parameter (172) of the at least one spectacle lens (114) by processing the at least one image (124) and by using the at least one signal (168) related to the position of the focus, wherein the at least one optical parameter of at least one spectacle lens (114) is determined by processing the at least one image (124) by further capturing the at least one object (130) in space in the at least one first distance to the at least one spectacle lens (114) and in the at least one second distance to the at least one camera (120),wherein the at least one optical parameter (172) of the at least one spectacle lens (114) is determined by using at least one marking comprised by the at least one spectacle lens (114), wherein at least one alteration of the at least one marking in the at least one image (124) is related to the at least one optical parameter (172) of the at least one spectacle lens (114) by applying a known relationship.The method (164) and the system (110) allow determining the at least one optical parameter (172) of the at least one spectacle lens (114) in a direct fashion by applying the at least one signal (168) related to the position of the focus as generated by the camera (120) as a measured value for the at least one optical parameter (172) of the at least one spectacle lens (114).
