ABSTRACT:
In a method of reading off the cross-section of the bezel of an eyeglass frame rim or surround at one point at least on the latter, a mobile feeler the position of which can be defined in a given system of coordinates is moved into line with the bezel. The head of the feeler successively sights at least two different points of at least one of the flanks of the bezel in order to deduce the coordinates of these points. The cross-section of the bezel read off in this way is used in trimming the lens to be mounted in the bezel.
