Title:
METHOD FOR PRODUCING A SEMI-FINISHED SPECTACLE LENS AND SEMI-FINISHED SPECTACLE LENS
Document Type and Number:
WIPO Patent Application WO/2019/158651
Kind Code:
A3
Abstract:
The invention relates to a method for producing a semi-finished spectacle lens (1) characterised by the step of identifying the semi-finished spectacle lens (1) by applying a removable adhesive (10) to the semi-finished spectacle lens (1), the adhesive (10) having a code (11) used to clearly identify the semi-finished spectacle lens (1). The semi-finished spectacle lens (1) also comprises a second code (25, 26) engraved into the semi-finished spectacle lens and the adhesive (10) is applied to the semi-finished spectacle lens (1), such that the adhesive (10) at least partially covers the second code (25, 26) engraved into the semi-finished spectacle lens. In particular, the adhesive can be applied directly to the semi-finished spectacle lens earlier, immediately after the moulding or injection moulding on the semi-finished spectacle lens or even before further surface treatment is carried out.
