Abstract: Vapor deposition apparatuses and methods for coating a substrate with at least two functional coatings that include a hydrophobic coating are described herein. Some embodiments include a vapor deposition apparatus with at least a first evaporator and a second evaporator, where the evaporator configured to apply the hydrophobic coating is raised above the other evaporator and is thus closer to the substrate. Others include methods of coating a substrate with such evaporators and different distances. Embodiments of the present disclosure can be useful for coating eyeglass lenses. Still others are disclosed.

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).
