Abstract

We developed a prototype system to reduce asthenopia by using stereoscopic 3-D images that moved in depth direction, and evaluated the effects of the system. Accommodative step response time, profiles of mood states and refractions were measured as indexes for examining the subject's visual fatigue. In young subjects, the accommodative relaxation time tended to be shortened by watching the images. This tendency indicates that the ciliary muscle quickly relaxed. In contrast, we observed an increase of accommodation in some aged subjects while they viewed the images. These results suggest that the work of the ciliary muscle is activated by observing the images. Our results suggest the possibility that viewing stereoscopic 3-D images can reduce asthenopia.
