PROBLEM TO BE SOLVED: To obtain central pieces which are not made specific by the intrinsic shapes of the lenses alone. SOLUTION: The central piece of a full rim spectacle frame has a left side full rim 2 for housing a left side lens, a right side full rim 4 for housing a right side lens, a bridge 6 for connecting the left side full rim and the right side full rim and two endpieces 8 and 10 which disposed on the respective sides of the left side full rim and the right side full rim reverse from the bridge 6. The two full rims, the bridge and the two endpieces are integrally molded by plastic. The two full rims are composed of closed elastic bands having flexibility. The central piece is assembled to the spectacles having the two lenses. The outer contour line of the lenses is slightly larger in the size than the inner contour line of the full rims. The full rims of the central piece of the spectacle are extended around the lenses and the shapes thereof comply with the shapes of the lenses. |
