Frame glasses are made from a mixture of metal and plastic. Some of the frames are made of metal, that is, partially or completely wrapped in celluloid; others are made of different materials in different parts of the frame, that is, the front frame is plastic, the temples are metal, or the front frame is metal. The temples are made of plastic; some use the above two methods, such as plastic for the eyebrows and nose bridge, stainless steel for the frame, and metal for the temples. The hybrid frame is exquisite and beautiful, giving a sense of elegance. Because the outer plastic is in close contact with the inner metal material, it is not easy to burn, which increases the strength of the frame.
