In this paper, injection molded polymer lenses are measured and analyzed to determine the effects of process parameters on the geometric errors and optical properties of the lenses. The significant factors and optimal combination of process parameters in the injection molding process could be determined by making use of the Taguchi method for screening the control factors via the analysis of variance (ANOVA) process. Finally, the effects of storage time on contour precision and the optical properties of the lens are also investigated. The contour precision and optical properties degraded six months after production with both significant factors and optimal combination of the factors being changed.
