PURPOSE: A one-piece type 3D glass frame is suitable for mass production and reduces the molding cost. CONSTITUTION: A weak connecting wire (3), which is soft and thinner than other parts, connects the top and the bottom between a lens unit (1) and each of temple parts (2a, 2b) and works as a hinge to rotate each of the temple parts. A glass frame is injection-molded as one piece. The weak connecting wire works as a hinge to rotate the temple parts and is fixed to both sides of the lens unit while each of the temple parts freely rotates within a certain angle range.
