Abstract

A method, a device, and a computer program for determining at least one optical parameter of a spectacle lens, and a method for manufacturing the spectacle lens using the at least one optical parameter are disclosed. The optical parameter denotes a value for a property of the spectacle lens which is adjusted during manufacture of the spectacle lens to achieve an intended correction of ametropia of at least one eye of a user of the spectacle lens. The method includes: a) capturing at least one image of a user wearing the spectacle lens; and b) determining at least one optical parameter of the spectacle lens by image processing the at least one image, wherein the at least one image contains an eye portion including at least one eye and/or a face portion adjacent to at least one eye of a user of the spectacle lens.
