Removable trim adjusting device for spectacles, has frame screwed through hole provided in lens and cooperating with another frame, by sliding between two points, for exerting trim`s convexity adjustment constraints between ends of trim

摘要

The device has a frame screwed through a hole (10) provided in an ophthalmic lens (7) by a pin (11) and a nut, where the pin passes through an oblong hole. The frame cooperates with another frame, by sliding between two points (A, B), for exerting trim`s convexity adjustment constraints between ends of a trim (2). The former frame has slides for guiding the sliding of the latter frame during the adjustment of convexity of the trim.
