Abstract: In preferred embodiments, the proposed eyeglass frame includes two glass-holding rims, each attached to an endpiece with upper and lower hinge loops coupled thereto. The endpiece includes split proximal and middle sections, and a solid distal section. The split includes a curvilined slit and a first window. The frame has two clamps with a second window and a groove. The clamp, preferably formed as a tube having a C-like or 0-like cross-section, operatively slides along the endpiece. The frame has two temples each with—an upper prong and—a lower prong furnished with outer protrusions, and—a middle prong therebetween, including—a strip-shaped portion,—a Z-shaped portion, and—a tongue with a tip. The lower and upper prongs diverge, forming a V-shape. The tongue and tip engage with the first and second windows during assembling.
