ABSTRACT:
A bridge of rimless glasses is fixed to lenses in a state where it is prevented from being deformed or varied by deformation prevention members, and a fixing portion between the bridge and lenses is not deformed, and hence the fixation at the fixing portion is ensured, thereby enhancing durability. Superelastic metallic material can be directly used by the bridge as the rimless eyeglasses. The bridge of rimless glasses is formed of a superelastic metallic material, and the bridge is fixed to the lenses by way of deformation prevention members. The deformation prevention members have pad arms and fixing bolts fixed thereto. The bolts are inserted into holes bored in the lenses. The pad arms have fitting portions fitted in recesses defined in the lenses. The bridge further comprises lens pads for ensuring fixation to the lenses while bringing into contact with ends of the lenses, fixing bolts to be inserted in holes bored in the lenses, and pad arms fixed to the lens pads, wherein the lens pads and said fixing bolts are fixed to the deformation prevention members.
