The accommodation-vergence mismatch has been considered as a cause of the visual fatigue induced in watching 3D display. We would propose the mismatch can be compensated by refractive power of adjustable-focus 3D glasses. From lens optics and geometrical considerations, we also developed equations that calculate required refractive power of the 3D glasses.… (More)
We measured brain waves of viewers watching the 2D, 2.5D, and 3D motion pictures, comparing them with one another. The relative intensity of α-frequency band of 2.5D-viewer was lower than that of 2D-viewer, while that of 3D-viewer remained with similar intensity. This result implies visual neuro-processing of the 2.5D-viewer differs from that of the… (More)
In this paper, it was studied how physics affected development of optometry in the United States, from aspects of formation and academization of optometry. It was also revealed that history of optometry was analogous to history of engineering. Optics in the 19th century was divided into electromagnetic study of light and visual optics. Development of the… (More)
Here is suggested a solution to the accommodation-vergence mismatch problem in 3D stereoscopic displays. It can be achieved by compensating the mismatched focal length with refractive power of adjustable-focus 3D glasses. The compensation would make vergence of human eyes match with position of virtual stereoscopic motion pictures, reducing visual fatigue.
