So-called 'rimmed' (1) or 'half-rimmed' spectacles consisting of two optical or sun lenses (2) with contiguous edges between which is a bridge (11) supporting the nose pads (12), said lenses being joined together by a central linking element (13) and by a rigid full frame (3) 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 around the edge of each lens (2) to support them, said spectacles being characterized in that the central linking means (13) is a vertical bar inserted between the extreme adjoining flanks of the contiguous edges of the lenses (2), respective profiles being formed in said flanks to engage with, by housing, complementary profiles formed on the flanks of the linking bar (13), in such a way as to locate and secure it, and hence the lenses (2), without additional mechanical fixing means.
