Abstract: This relates to a method including: detecting, using an optical sensor, an intrinsic optical feature of a lens member to be positioned on a manufacturing apparatus configured to apply an optical lens manufacturing operation to the lens member; and determining, using a processing unit, the position or orientation of the lens member in a framework of the manufacturing apparatus based on the intrinsic optical feature. The method can be used to position and block a lens member, i.e. a lens blank or a finished lens, on any type of manufacturing apparatus used for the manufacture of an optical lens. The intrinsic optical features have not been intentionally etched or engraved onto the lens member for the specific purpose of determining the position or orientation of the lens member.

Abstract: A method of preparing a lens blank for a further operation of surfacing to transform the lens blank into a surfaced lens for further transformation into a lens having a lens shape, the operation of surfacing including processing the lens blank so that the surfaced lens exhibits a crib diameter, the method being implemented using a processing module and comprising: based on input data (ID) which define the lens shape, defining a temporary crib diameter (Dtemp) so that said temporary crib diameter satisfies a set of constraints which includes at least: a first constraint whereby the temporary crib diameter (Dtemp) is large enough for the surfaced lens having said temporary crib diameter to be suitable to be processed into said lens, a second constraint whereby the temporary crib diameter is large enough for the surfaced lens having said temporary crib diameter to include a plurality of reference points defined on the lens blank and which together identify an optical center of the lens, choosing the crib diameter as a function of the temporary crib diameter (Dtemp), said choosing the crib diameter being configured so that, when a step cribbing configuration is destined to be applied to the operation of surfacing, said crib diameter is chosen among at least one predetermined discrete value (Vali).

Abstract: Disclosed is a method implemented by computer for determining a lens blank intended to be used for the manufacturing of a finished optical article. The method includes: —a virtual volume data determining step, during which virtual volume data are determined based at least on finished optical article data representative of the volume of the finished optical article and over-thickness data representative of over-thickness requirements, the virtual volume data are determined so that the virtual volume defined by the virtual volume data includes the volume of the finished optical article volume of the finished optical article and the over-thickness, —a lens blank determining step, during which a lens blank is determined based on the virtual volume data so as to include the virtual volume defined by the virtual volume data.

Abstract: Disclosed is a method for determining location of a lens machining tool (24) having an offset location according to a first direction (Y) smaller than a first predetermined threshold, including the steps of manufacturing a calibration piece (10) according to a predetermined theoretical geometry by using the lens machining tool for providing a at least partially annular groove in a main surface of the calibration piece, the at least partially annular groove being configured to form at least one sharp edge defining a slope discontinuity on the main surface; measuring a distance between the at least one sharp edge and a turning center of the calibration piece for providing data of geometrical characteristics of the calibration piece; and deducing from the measured data a location of the lens machining tool according to a second direction (X) distinct from the first direction.
