METHOD FOR DETECTING THE PRESENCE OR ABSENCE OF AN OPHTHALMIC LENS, IN PARTICULAR A CONTACT LENS, WITHIN A RECEPTACLE

摘要

The present invention relates to a method for detecting the presence or absence of an ophthalmic lens ( 10 ), in particular a contact lens, in a receptacle ( 1 ). The method comprising the steps of: - the absorption of the material for making the ophthalmic lenses (A L - detecting infrared rays emitted from at least a portion (3) of said receptacle (1) the ophthalmic lens (10) is accommodated the estimate, analyzing the detected infrared light in a spectral part where ) is significantly different from the absorbance (AR ) of the material from which the receptacle is made, and - from the analysis of the spectral part, of the ophthalmic lens 10 in the receptacle. detecting the presence or absence.
