ABSTRACT:
Glass frames have a thin basic frame which mechanically absorbs the load on the glasses. A thin layer of soft material, such as silicon rubber or plastic foam is connected to the frame, at least on the rear eyebrow and nose rest and pad portions. The soft material may be separately formed and mechanically connected to the frames or formed on the frames.
