Abstract (en)
The invention relates to a method and a device for detecting the presence of an ophthalmic moulding consisting of a biocompatible polymeric material, especially an ophthalmic lens, particularly a contact lens, in a package. The invention solves the problem through the use of a spectroscopic process. Packages containing a moulding, especially a contact lens, have a characteristic change in their measuring spectrum compared with a package without a contact lens. By evaluating the spectra, it is possible to determine whether or not there is a contact lens in a package. In particular, by using the measuring method according to the invention, one can determine directly after the filling procedure whether there is a contact lens in the package. In addition, the invention is suitable for checking whether contact lenses are contained in the already sealed package. During this procedure, the package remains intact. <IMAGE>
