Abstract
Disclosed is a method for verifying the mounting of at least one ophthalmic lens in a frame of a pair of spectacles designed to be worn by a subject, the method including the steps of: obtaining a test image of the frame in which the at least one ophthalmic lens is mounted, the at least one ophthalmic lens including at least one marking visible in the test image; comparing the test image of the frame with a reference image of the frame worn by the subject without the at least one ophthalmic lens; and verifying the mounting of the at least one ophthalmic lens in the frame based on the previous comparison.
