The renovation of the glasses frames first depends on the type of material used to make the frame, whether it is a plastic frame or a metal frame. The characteristic of plastic spectacle frames is easy processing and lightweight wearing.

Plastic glasses frames are divided into two types: thermosetting and thermoplastic. Thermoplastic glasses frames are not easily damaged and are easy to repair. They are characterized by softening when exposed to heat and have plasticity, which can be softened using different methods. For example, by using the hot gas of the kerosene lamp shade and the hot gas outside the electric lamp bulb, the spectacle frame is heated for 2-5 minutes, so that the length, curvature, and height of the leg can be adjusted as required after the frame becomes soft. Another method is to place the part of the eyeglass frame that needs to be repaired in a hot water cup for 3-5 minutes, soften it, and then remove it for repair. On hot summer days, the glasses frame can be naturally repaired.

The renovation of metal spectacle frames is more convenient than plastic spectacle frames. If the bottom frame of the glasses contacts the cheeks, it is very uncomfortable to wear, especially when it is cold and the air is blowing, causing the lenses to appear foggy and unclear. The correction method is to bend the glass's feet upwards at an angle to move the bottom of the glass frame outward. When the metal handle plastic pad on the glasses frame is asymmetrical in height, it is necessary to adjust the shape and position of the small pad. Pointed nose pliers can be used to complete the adjustment and adjust according to the shape of the nose bridge. If the frame you are wearing is skewed, you need to have it repaired by a professional.
