Abstract

Accommodation and convergence were measured simultaneously while subjects viewed 2D and 3D images. The aim was to compare fixation distances between accommodation and convergence in young subjects while they viewed 2D and 3D images. Measurements were made using an original machine that combined WAM-5500 and EMR-9, and 2D and 3D images were presented using a liquid crystal shutter system. Results suggested that subjects’ accommodation and convergence were found to change the diopter value periodically when viewing 3D images. The mean values of accommodation and convergence among the 6 subjects were almost equal when viewing 2D and 3D images respectively. These findings suggest that the ocular functions when viewing 3D images are very similar to those during natural viewing. When subjects are young, accommodative power while viewing 3D images is similar to the distance of convergence, and the two values of focusing distance are synchronized with each other.
