Abstract
The invention relates to spectacles of the rimless-type, comprising a bridge interconnecting two lenses, and two side arms that are hinge-less wire structures suitable for flexing. According to the invention, each side arm presents a distal end arranged to fasten to the side zone of the corresponding lens, said distal end being substantially J-shaped, with a long portion passing through a through bore in the lens, with a pliable clamping plug being interposed that holds the distal end in place, and an anti-pivot short portion extending backwards and passing into an outwardly-open side notch, without clamping the lens between said long portion and said short portion, the central portion that interconnects the long portion and the short portion extending close to the front face of the lens.
