为了研究在观看立体图像时，聚散和调节的分离是否是导致视觉疲劳的原因，我们研究了使用棱镜观看没有聚散变化的模拟立体图像系统约一小时后的视觉疲劳。疲劳评估的主观报告的症状，调节阶跃反应，相对聚散极限，和视觉诱发电位（VEP）。结果表明，当分离量较大时，观察后相对聚散度极限下降，表现为视疲劳。受试者休息后，他们的相对聚散极限恢复。
To investigate whether the dissociation of vergence and accommodation is responsible for visual fatigue in watching stereoscopic images, we studied the visual fatigue after approximately one hour of watching a simulated stereoscopic image system without vergence change using prisms. Fatigue was assessed by subjective reports of symptoms, accommodation step responses, relative vergence limits, and visual evoked potentials (VEP). The results showed that when the amount of dissociation was large, relative vergence limits decreased after watching which means visual fatigue. After subjects took some rests, their relative vergence limits recovered.
