STEREOSCOPIC GLASSES, METHOD FOR DESIGNING SPECTACLE LENS USED IN SAME, AND METHOD FOR OBSERVING STEREOSCOPIC IMAGE

摘要

Provided are stereoscopic glasses whereby visual fatigue in binocular stereoscopic display can be alleviated by a simple structure. In these stereoscopic glasses 10, in order to increase the allowed range of consistency of vergence and accommodation for enabling comfortable stereoscopic vision in glasses-type stereoscopic display, wide-focus lenses 16a, 16b having a wide focal length are incorporated so as to overlap in the light transmission direction with optical filters 14a, 14b, and visual fatigue due to vergence-accommodation conflict during stereoscopic image observation is reduced.
