The invention relates to rimless eyeglasses comprising a bridge (13) interconnecting two lenses (V), and two side branches (11) connected to respective side zones of the corresponding lenses (V). In accordance with the invention, each side branch (11) essentially presents a wire structure comprising two main portions (11.1, 11.2) extending towards the rear or said branch, said main portions extending forwards, passing through two through holes (21, 22) in the lens (V), and being connected together in the vicinity of the front face of said lens by a front portion (11.3), a flexible bushing (15) being interposed in each through hole (21; 22) in order to clamp the associated main portion (11.1; 11.2) so as to hold the side branch (11) in place on the corresponding lens (V).
