A super multi-view (SMV) 3D display has been proposed for reducing conflict between accommodation and vergence, which is a possible cause of visual fatigue. Previous studies reported that measured accommodative responses to SMV images were similar to those of real objects. We need to measure vergence response along with accommodative response to investigate the conflict between them. In this study, we measured accommodative and vergence responses while observers were viewing a static visual target presented on an SMV display. We also examined the responses to two-view displays and real objects for comparison. The results show that the SMV display induced a natural accommodative response relative to the two-view 3D display while no difference was found among the viewing conditions of the vergence response. This suggests that the SMV 3D display is effective for reducing conflict between accommodative and vergence responses.
