Method of Manufacturing Optical Article and Optical Shaping Apparatus
16 Sep 20
A method of manufacturing an optical article, wherein an output light flux generating process of generating an output light flux by inputting a light from a light source to an output setting element having a repetition structure; a cured layer forming process of forming a cured layer at an irradiation area that is formed in correspondence with the output area by introducing the output light flux through a projection optical system into a container in which light-curable resin is contained and a stage is arranged and condensing the output light flux; and a stage moving process of moving the stage in a desired distance along the direction of the output flux propagating, are sequentially performed in this order and an irradiation variation process of varying the irradiation area in the cured layer generating process are further included, thereby the optical article is formed on a surface of the stage.

an Improved Method of Preparing a Lens Blank for an Operation of Surfacing Thereof
2 Sep 20
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).

Method for Packaging a Spectacle Lens
19 Aug 20
Disclosed is a method for packaging an optical lens including two faces and a peripheral edge, at least one of the faces having a convexity marked by a peak point, the method including the following steps: a step of depositing a protective strip made from a rigid material at least partially along the edge, the width of the strip extending beyond the peak point of the convex face of the lens; a step of inserting the lens into an envelope delimited by a wall; a step of positioning the lens in the envelope, such that the protective strip acts as a spacer in order to maintain a distance between the wall of the envelope and the convex face of the lens and thus preventing any contact between the wall and the face.
