A nose bearing assembly is secured onto a central area of the spectacles, directly on the optical or sun lenses, or on the bridge connecting the lenses or on a rim frame of the latter, each of the two nose bearing assemblies having a pad intended to contact the nose ala of a user and carried by a pad-bearing arm connected to the spectacles, characterized in that the pad is made of a elastically deformable material and is divided into two areas, i.e. an upper area for receiving a free end of the pad-bearing arm or securing and stiffening the pad in area, and another lower area capable of elastic deformation and of floating freely in all directions in order to obtain a self-adjustment of the pads independently from the morphology of the nose of the user when in contact with the latter.
