3D display technologies have been linked to visual discomfort and fatigue. In a lab-based study with a between-subjects design, 433 viewers aged from 4 to 82 years watched the same movie in either 2D or stereo 3D (S3D), and subjectively reported on a range of aspects of their viewing experience. Our results suggest that a minority of viewers, around 14%, experience adverse effects due to viewing S3D, mainly headache and eyestrain. A control experiment where participants viewed 2D content through 3D glasses suggests that around 8% may report adverse effects which are not due directly to viewing S3D, but instead are due to the glasses or to negative preconceptions about S3D (the 'nocebo effect'). Women were slightly more likely than men to report adverse effects with S3D. We could not detect any link between pre-existing eye conditions or low stereoacuity and the likelihood of experiencing adverse effects with S3D.
3D显示技术已被认为与视觉不适和疲劳有关。在一项基于实验室的、采用组间设计的研究中，433名年龄在4岁至82岁之间的观众观看了同一部电影的2D或立体3D（S3D）版本，并主观报告了他们观影体验的一系列方面。我们的研究结果表明，少数观众（约14%）在观看S3D时会出现不良反应，主要是头痛和眼疲劳。一项对照实验让参与者通过3D眼镜观看2D内容，结果表明约8%的人可能报告不良反应，这些反应并非直接由观看S3D引起，而是由于眼镜或对S3D的负面先入之见（“反安慰剂效应”）。女性比男性更有可能报告S3D带来的不良反应。我们未发现既往眼部疾病或低立体视锐度与S3D不良反应发生可能性之间存在任何关联。
