Comparison of 2D and 3D Vision Gaze with Simultaneous Measurements of Accommodation and Convergence

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 three times, 40 seconds each, using 2D and 3D images. The result suggests that ocular functions during viewing of 3D images are very similar to those during natural viewing. Previously established and widely used theories, such that within a VR system eyes must maintain accommodation on the fixed LCD screen, may need to be corrected.
