Abstract: This method for retrieving at least one optical parameter of an ophthalmic lens comprises: obtaining (10) an image of a first and second patterns by using an image capture device located at a first position; from that image, obtaining (12) a first set of data from at least a part of the first pattern that is seen through the lens by the image capture device and obtaining (14) a second set of data from at least a part of the second pattern that is seen directly i.e. outside the lens by the image capture device; retrieving (16) the at least one optical parameter by using the first and second sets of data and taking account of relative positions of the image capture device, the lens and the first and second patterns.
