Technical Field

[0001] The utility model relates to the technical field of eyeglass frame devices, in particular to an optical eyeglass frame with adjustable width. Background Art

[0002] Optical glasses are composed of lenses and frames. Frames are usually composed of the main parts such as the ring, nose pads, studs and temples. In addition to the above parts, there are also foot covers, stud screws, hinge screws, etc. The frame is an important part of the glasses. It mainly supports the lenses. The beautiful-looking frames can also play a role in aesthetics. The main materials are metal, plastic or resin, natural materials, etc. According to the style, it can be divided into full frame, half frame, frameless and other types.

[0003] The size of existing eyeglass frames often needs to be selected according to the size of the eyeglass lenses and the size of the wearer's head. However, the size of the lenses is often adjusted according to the wearer's choice of style and degree requirements. At the same time, the face of the wearer will also change according to the growth of the body or the weight gain or loss of body shape. This results in the inability of existing eyeglass frames to adjust their width according to the replacement of lenses and body development of the wearer, so that the wearer can only select the eyeglass frames again, which not only increases the cost of wearing glasses for the wearer, but also causes waste of eyeglass frames. Therefore, the existing non-adjustable eyeglass frames are still inconvenient when used.
