The invention discloses a processing method of a high-reflection-rate glass lens. The processing method comprises the following steps of 1, cutting, a plate material is cut by using a cutting machine;2, forming, forming is carried out through a forming machine; 3, performing fine carving, after the shape is formed, an angle is engraved according to a jig; 4, polishing, a rough surface is polishedat one time; 5, secondary polishing, secondary polishing is carried out to form a mirror surface; 6, clearing, polishing powder on the surface of the polished lens is clearing away, and sub-gram is prevented; 7, checking the appearance, the appearance and the surface are detected by using lamplight; 8, measuring, the size is detected through referring a drawing paper; and 9, the finished productis put into a storage. According to the processing method, a corresponding to-be-detected product can be prevented from being excavated and cut out in a regular rectangle, various shapes can be achieved, and any of angle adjustment can be achieved, so that the visible light can be well displayed on the lens under the condition that an angle exists.
