The composition of the glasses
- Lens: Also known as the mirror center, it is suitable to be placed in the frame, so it is called the mirror center. It can be horizontal or vertical.
- Nose bridge: connect the left and right mirror circles or directly connect with the lens. The beams are either placed directly on the nose or supported on the nose by stipules.
- Nose pads: including stipules, stipules box and stipules. The stipules are in direct contact with the nose and play the role of supporting and stabilizing the frame. Some cast-molded spectacle frames can have no stipule stems and stipule boxes, and the stipules are connected to the mirror ring, which is common in acetate spectacle frames.
- Pile head: The connection between the mirror ring and the mirror angle is generally curved.
- Temples: The hooks are placed on the ears, which can be moved and connected with the pile head, which plays the role of fixing the mirror ring. When matching glasses, special attention should be paid to the size of the temples, which is directly related to wearing comfort.
- Hinges: A joint connecting the pile head and the mirror foot.
- Locking block: Tighten the screws to fasten the locking blocks on both sides of the opening of the mirror ring, so as to fix the function of the lens.
