A pair of glasses frame is usually composed of mirror ring, nose support, pile head, mirror foot and other main components. In addition to the above parts, there are foot covers, bracket screws, hinge screws, etc.Lens ring (frame): the assembly position of the lens. The lens is fixed in the groove or hole with metal wire, nylon wire and screws, which affects the cutting of the lens and the shape of glasses.
Nose bridge: connect the left and right lens rings or directly with the lens. The bridge of the nose is either placed directly on the nose or supported on the nose by stipules.Nasal bracket: including petiole, stipule box and stipule. The stipules are in direct contact with the nose and play a role in supporting and stabilizing the mirror frame. Some cast frames can have no stipule stems and stipule boxes, and the stipules are connected with the mirror ring.
Pile head: the connection between the mirror ring and the mirror foot is generally arc-shaped.Mirror foot: the hook is installed on the ear and can be moved. It is connected with the pile head to fix the mirror ring.Hinge: the joint connecting the pile head and the mirror foot. Locking block: tighten the screws and fix the locking block on both sides of the opening of the lens ring to fix the function of the lens.
Full frame: it is the most commonly used frame type, which is characterized by firmness and easy setting, and can cover part of the lens thickness.Half frame: the half frame is made of fine nylon yarn. As a part of the frame edge, it is light, gives a light and unique feeling, and is relatively strong.
No frame: this kind of frame has no lens ring, only metal nose bridge and metal foot. The lens is directly connected with the nose bridge and lens foot through screws, and it is usually necessary to drill holes on the lens. Frameless frame is lighter and more fashionable than ordinary frame, but its strength is slightly poor.
Combo frame: the front frame has two sets of lenses, one of which can be turned over, and is usually used indoors and outdoors.Folding frame: the frame can be folded in four or six folds, mostly reading glasses.Nylon wire frame: use very thin nylon wire as part of the frame edge, and grind the lower edge of the lens flat through special grinding.

Therefore, the weight is very light, giving people a feeling of lightness and chic, and it is relatively strong.Eyebrow frame: eyebrow frame is similar to half frame mirror frame. The upper half of the frame only has a round wire similar to eyebrows, and the edge of the lower half of the frame uses a very thin nylon wire. The style is quite fashionable.
