This study aimed to investigate the changes in stress distribution of each compound eye during optical precision molding of curved compound eye lens. This paper built a finite element model using MSC.Marc to present a simulation study of the molding and holding stages of the glass lens under different process parameters. For this, the effect of temperature, molding velocity, and molding pressure on the stress of each compound eye, as well as the molding pressure and displacement curves, were obtained. Our findings for spherical preforms with a large deformation showed that the constant velocity molding condition increased downward displacement, leading to excessive external forces that prevent stress relaxation. The holding stage was further studied to obtain the pattern of effect of different holding forces on the filling effect and stress distribution in the compound eye.
