Abstract
The three-dimensional optometer which can measure simultaneously three major ocular functions-eye accommodation, eye movement and iris area change-in a real working situation was applied to measure visual responses gazing at (1) actual artworks, and (2) planes presented by moving random dots on a CRT. Both of the stimuli were presented at the fixed positions from the subjects and the measurements were performed under a normal lighting condition. Two subjects showed clear accommodative responses for the both stimuli. The paper discussed that the result infers a plausible cause for the visual fatigue induced by viewing at stereoscopic pictures.
