ABSTRACT:
So-called ‘rimmed’ or “half-rimmed” spectacles have two optical or sun lenses with contiguous edges between which is a bridge supporting the nose pads. The lenses are joined together by a central linking element and by a rigid full frame or a partial frame comprising a rigid upper part which is continued by a lower part in the form of two flexible and transparent cords housed in a groove running a the edge of each lens to support them. The spectacles are characterized in that the central linking means is a vertical bar inserted between the extreme adjoining flanks of the contiguous edges of the lenses, respective profiles being formed in the flanks to engage with, by housing, complementary profiles formed on the flanks of the linking bar, in such a way as to locate and secure it, and hence the lenses, without additional mechanical fixing devices.
