The invention relates to the field of production of optical glass, in particular to an optical glass recycling process. The optical glass recycling process comprises the following steps that 1, an optical glass smashing device is prepared; 2, optical glass is cut; 3, the optical glass is unloaded into receiving sliding grooves; 4, a separation unit separates waste optical glass from optical glasson a supporting board; 5, the waste optical glass is crushed into optical glass particles through a crushing nail; and 6, the optical glass particles slide to receiving cloth, the two receiving sliding grooves are driven to get close to each other, and the optical glass inside the receiving sliding grooves is polished. By the adoption of the technical scheme, leftover materials can be automatically smashed and collected, and the optical glass is polished at the same time.
