Abstract: 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.
