Abstract
In this study, we perform a comparative analysis on the physiological changes of the miosis area before and after observing binocular 3D images using liquid crystal shutter glasses under various visual distance (2m and 4m) and indoor illumination levels. The miosis area is measured by an infrared rays optometer. The efficiency of viewing methods of 3D images in the aspect of ergonomics is considered.
From the experiments we obtained the following result:
(1) The miosis area decreases after viewing 2D images and 3D images and the tendency is more critical with 3D images.
(2) The indoor illumination has a significant effect on the miosis area in both 2D images and 3D images. Particularly, it is revealed that the effect is more obvious in 3D images.
(3) Less change of miosis area is observed under the indoor illumination. Thus, if we only focus on the visual load on the eye for viewing 3D images it will be better to use indoor illumination.
