The present invention relates to supply systems for providing spectacle ophthalmic lenses. Said supply systems have improved efficacy, in particular with respect to lens blank picking performance and/or lens manufacturing performance. The present invention also provides a lens blank with an identifier, wherein the identifier allows the subsequent retrieval of a measured value of a geometrical parameter of said blank. The present invention further provides methods for providing a lens blank that is identifiable, in that it allows the subsequent retrieval of a measured value of a geometrical parameter of said blank; methods for picking a lens blank; and methods for making a finished lens. The present invention lies particularly in that at least a measured value of at least one geometric parameter of a semi-finished spectacle lens blank is used instead of the corresponding nominal value of said at least one geometric parameter. |
