Abstract
The purpose of this study is to analyse on human eyes. Some of the autonomic nervous system effects analysis systems developed in this study are expected to be useful for obtaining much data regarding the pupil light reflex and convergence reflex. In observations of the pupil litht reflex using the aforementioned systems, we found small pupil diameter variation due to parasympathetic nervous activity from the velocity phenomenon of pupil contraction and dilation. We also observed pupil focusing with alternate movements of contraction and dilation at about 0.5Hz in analysis of the pupil convergence reflex.
