The parts include lenses, and/or nose pads or nosepieces, end pieces for coupling temples, a bridge, a front of the eyeglass frame or mask, and hinges and/or hinging elements. Contiguous areas of different thickness are provided, sized so that the area with higher thickness differs from that with lower thickness by a maximum value of between 1.5 mm and 6 mm, the contiguous areas being joined by a junction having a radius of curvature between 0.5 and 5 mm.
