Abstract

The invention relates to a semi finished lens blank having two defined faces assembled together a first face being intended for producing lenses in a first subset of wearer data and/or frame data and a second face being intended for producing lenses in a second subset of wearer data and/or frame data. The number of semi finished lens blanks for a given line can thus be reduced.
