(57) An apparatus for cutting coloured and/or polarized lenses for spectacles comprises
a supporting construction, having a bearing shoulder for bearing the outer contour
of the spectacle frame for holding the lenses.
On the supporting construction is mounted a cutting tool, arranged near the bearing
shoulder on the side thereof opposite to the spectacle frame bearing side, the cutting
tool being controllably driven in order to progressively cut that portion of the additional
lens, previously mounted on the frame, projecting from the frame and overlaying the
bearing shoulder in the direction of the cutting tool, while the frame is driven,
with respect to the bearing shoulder, so as to cause the bearing shoulder to follow
the outer contour of the frame.
