This paper describes an examination of a stereoscopic 3-D display system using a correction lens. The purpose of the system is to reduce the accommodation and convergence difference during viewing stereoscopic 3-D images by using simple technique. This correction lens is a mono-focal lens, and added to the polarized filter glasses. In this study, the authors carried out three experiments in order to examine the appropriate utilization conditions and effects of the correction lens. In experiment 1, the refractive power of correction lens was examined under six conditions in which distances of accommodation and convergence were theoretically equal. In experiment 2, the presenting condition of stereoscopic 3-D images suitable for the correction lens was examined by measurement of refractions during viewing visual target that moved in depth direction. In experiment 3, the effectiveness of the correction lens was examined by using the utilization conditions obtained in experiment 1 and 2. From the results of the experiments, the following conclusions were drawn. (1) Correction lenses shift the accommodation distance. (2) Using a correction lens with the appropriate refractive power and setting the appropriate conditions for presenting stereoscopic 3-D images reduced the difference between accommodation and convergence. (3) The use of a correction lens affected the subjective symptoms of asthenopia.
