In this paper, the numerical simultion about press molding of glass lens using the finite element method is investigated. Thermo-viscoelastic properties of the glass were estimated using undirectional compression creep test based on traditional thermoviscoelastic theory. Numerical simulation for molding press of the glass was carreid out by finite element method using universal FEM code (ANSYS ver.12.0). Relation between molding temperature and pressure for complete transcription was investigated and the adaptive condition of press molding was predicted. The effect of cooling rate for residual stress and shape error was investigated by the present numerical simulation.
