Stereoscopic virtual reality (VR) headsets display vergence cues to object distance but present images at a fixed focus, resulting in a vergence-accommodation conflict (VAC). This study examined the effects of introducing or reducing the VAC with optical lenses in a targeted reaching task implemented in both VR and the real world. Contrary to previous reports of reduced visual performance and fatigue with the VAC, we found no evidence of impairments to visually guided movement for either the real-world or VR-based versions of the task. As lenses also magnify or minify the image, a control experiment was conducted to examine the effects of image minification on movement in VR. No significant effects of optical correction or image minification were found, suggesting that the VAC does not adversely affect visually guided movement over the durations employed in this study.

虚拟现实中的视觉引导运动可以容忍聚散调节冲突

立体虚拟现实 (VR) 耳机显示物距的聚散提示，但以固定焦点呈现图像，从而导致聚散调节冲突 (VAC)。这项研究检验了在 VR 和现实世界中实施的目标到达任务中使用光学镜头引入或减少 VAC 的效果。与之前关于 VAC 导致视觉表现下降和疲劳的报道相反，我们没有发现任何证据表明无论是现实世界版本还是基于 VR 的任务版本，视觉引导运动都会受到损害。由于镜头也会放大或缩小图像，因此进行了一项对照实验来检查图像缩小对 VR 中运动的影响。没有发现光学校正或图像缩小的显着影响，这表明 VAC 不会对本研究中使用的持续时间内的视觉引导运动产生不利影响。
