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 3D-viewer.
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. The compensation we proposed is supposed to reduce the visual fatigue of 3D display.
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.
Development of optometry in western countries was studied on a viewpoint of the history of science. It was revealed that optometry had been formed on the basis of optics, a branch of physics, to which biomedical study was added. Optometry can be defined as a pioneering interdisciplinary field of study and as biomedical physics of the 19th century. It is pointed out that population-geographic factors have affected on the development of optometry in the U. S. A. and Australia. European development model is suggested for a strategy for the next-generation development of Korean optometry, rather than American model.
