Abstract: Fixtures and a fitting structure for eyeglass lens are provided wherein the eyeglass lens is easily fitted while preventing cracks in the eyeglass lens during the fitting and preventing loosening of the eyeglass lens during being used. Tapped holes are formed at the respective locations in the inside and outside rims of the eyeglass lens so as to be fitted by pipe screws having threads on at least the internal peripheral faces thereof. A fitting portion of a bridge or a fitting portion of an end piece is located over the top surface of the eyeglass lens so that a hole at the end of the fitting portion is aligned with the tapped hole of the eyeglass lens. Setscrews are inserted into the holes of the fitting portions from the topside of the eyeglass lens so as to be screwed and tightened with the threads in the internal side of the pipe screws.
