In the grinding process of the optical lens, the subsurface damage such as dislocation and microfracture will weaken the strength of the optical lens, affect its long-term stability, and thus reduce the final quality of the optical lens. Therefore, in order to improve the processing quality and efficiency of optical lenses and meet the growing market demand of optical lenses, effective methods must be sought to remove the subsurface damage. In the present stage of the optical lens subdamage simulation research, simulation modeling as an important part of the research process, for the formation of subsurface damage can be more detailed simulation analysis, to minimize the simulation results and actual engineering error, help to combine experiment and theory, guide the grinding of optical lens processing. This paper conducts numerical simulation and analysis of subsurface damage of optical lens to provide reference for related techniques.
