Abstract
A system for monitoring the position of a blocking device on an ophthalmic lens () having at least one marking comprises: —a mechanical structure adapted to cooperate with the blocking device; —an image sensor () observing the ophthalmic lens (); —a control unit () connected to the image sensor () and configured to produce an image having a point of reference with a determined position with respect to the mechanical structure and at least part of the ophthalmic lens () including said marking; and—a user interface () adapted to display a blocking device positional compensation proposal for an automatic positional compensation or for a manual positional compensation based on the comparison to a predetermined threshold of a distance between the point of reference and the marking on the image. A corresponding method and a method for edging an ophthalmic lens are also proposed.
