Rimless spectacles and hinge pieces are disclosed, where the hinge pieces each include an abutment part having an abutment surface extending parallel to and in substantial abutment with a side surface of the respective lens and at least two corresponding pins, that are fastened to the abutment part and extend into corresponding holding holes of the lenses. The pins are rigidly connected to the inner side surfaces of the corresponding holes, so that the pins substantially are prevented from gaining an angular displacement relatively to the holes in the lens. The two pins form together with the abutment part a three-sided contact area between the hinge piece and the lens. A force or torque applied to the hinge piece is distributed over this contact area, since the construction substantially prevents any mutual movements or displacements between the hinge piece and the lens, and the stresses are consequently distributed and fatal stress concentrations leading to damages and fractures of the lens are avoided.
