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.
A method for producing a semi-finished spectacle lens, the method comprising:
A semi-finished spectacle lens with a detachable sticker for producing a finished spectacle lens, wherein the sticker has a code for unique identification of the semi-finished spectacle lens during at least one production step of the semi-finished spectacle lens or the finished spectacle lens, wherein the sticker identifies at least one reference region or a coordinate system of the semi-finished spectacle lens, wherein the sticker is applied to the semi-finished spectacle lens with a positioning accuracy selected from a group of ±1 mm, ±500 μm, ±200 μm, ±100 μm, ±50 μm, and ±20 Ξm relative to a rotation around a center of the semi-finished spectacle lens, and an angular accuracy selected from a group of ±1° and ±0.5° relative to the center of the semi-finished spectacle lens.
A method of identifying a semi-finished spectacle lens during manufacturing, the method comprising:
