Abstract
In the present study, we examined the visual accommodation of subjects who were gazing fixedly at stereoscopic images on two different displays: a cathode ray tube (CRT) with the subjects wearing liquid crystal shutter glasses and a liquid crystal display (LCD) with the subjects not wearing liquid crystal shutter glasses. In Experiment 1, we measured accommodation in subjects viewing a moving stereoscopic image. In Experiment 2, we measured accommodation in subjects viewing moving stereoscopic images on an LCD and a CRT. In Experiment 3, we measured accommodation in subjects viewing a stereoscopic image moving from far to near on an LCD. In Experiment 4, we measured of accommodation in subjects viewing moving stereoscopic images (stereoscopic display mode) and non-stereoscopic images (2-D mode) on an LCD. The results suggested, the ciliary muscle is repeatedly strained and relaxed while the subject views the moving target. In the present study, the subjects’ accommodative amplitude was changed when the target moved from the near to far point, and vice versa.
