7 Claims

1. A method of reading the outline of the bezel of a rim of an eyeglass frame, the method comprising the steps of putting a feeler into contact against the bezel and of feeling the bezel by sliding or running said feeler along the bezel, the feeler being actuated by actuator means along at least a first axis normal to the general plane of the rims of the frame, wherein during reading, the overall force delivered by the actuator means is caused to vary, either continuously or in steps, as a function of the position of the feeler along the first axis and wherein the overall force delivered by the actuator means comprises an axial component parallel to the first axis and a transverse component orthogonal to the first axis, one and/or the other of said components varying as a function of the position of the feeler along the first axis, in such a manner that that the axial component of the overall force is directed towards an inside of the frame that is to be positioned facing the eyes of the wearer.
