By relaxing the contracted focus-adjustment muscles around the eyeball, such as the ciliary and extraocular muscles, improvement of the pseudo-myopia is expected. This understanding has led to the accommodation training in which the visual target is given by stereoscopic video clips. However, it is pointed out that the motion sickness can be induced by viewing stereoscopic video clips. In the measurement 1 of this study, we verify whether the new 3-dimensional (3D) technology reduce the severity of motion sickness in accordance with the stabilometry. We then evaluate short-term effects of the accommodation training utilizing new stereoscopic video clips on foreign labors (11 females) suffering from eye fatigue in the measurement 2. The foreign workers were trained in 3 days. We could show that the new 3D technology reduce the severity of motion sickness in accordance with the stabilometry. The effect of the accommodation training utilizing the new 3D video clip was investigated in foreign labors suffering from eye fatigue, and the eye strain was reduced by the continuous accommodation training for a short-term period.
