Abstract
The present invention relates to a method and a lens detection station for detecting the presence or absence of an ophthalmic lens capable of absorbing UV-light, in particular a contact lens, in a receptacle. The method comprises the steps of:
- irradiating at least a portion of said receptacle where said ophthalmic lens is supposedly accommodated with UV-light, said receptacle having an absorbance for said UV-light which is significantly different from that of the ophthalmic lens,detecting UV-light coming from said irradiated portion of said receptacle where said ophthalmic lens is supposedly accommodated,analyzing said detected UV-light, andfrom said analysis of said detected UV-light determining the presence or absence of a said ophthalmic lens.
