摘要：We studied visual fatigue in subjects after they viewed a simulated stereoscopic images with their vergence angles varied using rotary prisms to investigate whether the dissociation of vergence and accommodation is responsible for the fatigue. After approximately one hour of watching, the fatigue was assessed through subjective reports of symptoms, accommodation step responses, relative vergence limits, and visual evoked potentials (VEP). Relative vergence limits decreased and the latency of VEP increased after watching when the amount of dissociation was large and the dissociation changed over time, reflecting visual fatigue. After subjects rested, their relative vergence limits recovered.
