A method for producing a semi-finished spectacle lens and a semi-finished spectacle lens includes identifying the semi-finished spectacle lens by applying a removable sticker having a unique code to the semi-finished spectacle lens. The semi-finished spectacle lens has an embossed code that is engraved into the semi-finished spectacle lens. The sticker is applied to at least partially cover the embossed code. The sticker can be applied directly onto the semi-finished spectacle lens early in the manufacturing process, for example immediately after molding or injection molding. The sticker can also be applied to the semi-finished spectacle lens before further surface treatment is carried out.

The invention concerns a method for producing an optical article suitable for edging comprising an antifouling layer on which there is deposited a temporary overlayer for assisting with edging, comprising: depositing, on an optical substrate, an organic antifouling layer comprising at least a fluorinated polymer compound comprising hydrolysable functions; and depositing, on the antifouling layer, an overlayer for assisting with edging, of mineral nature, comprising one or more metal fluorides and/or one or more metal oxides or hydroxides;

method characterised in that it further comprises a step of accelerated grafting of the antifouling layer chosen from:

(a) a treatment of the deposited antifouling layer in a humid atmosphere of the deposited antifouling layer and

(b) a catalytic treatment in the acidic or basic vapour phase of the deposited antifouling layer.

A fixture used in the manufacture of an eyepiece, to cut the eyepiece to a particular shape, and a method of using the fixture to cut the eyepiece to have a desired shape. Embodiments are directed to a configurable fixture to align, hold, and protect a plastic sheet (e.g., a wafer) while a laser cutting apparatus is cutting one or more eyepieces out of the wafer. During the cutting, the fixture protects the eyepieces from reflected laser light by providing voids around the laser cutting lines, and by supporting each eyepiece near its perimeter. The fixture can be quickly rearranged for different eyepieces, different eyepiece shapes, and/or different plastic sheet sizes.
