摘要:

近年来,随着科学技术的发展,立体视频显示终端的应用范围越来越广泛。与此同时,其对于人眼乃至全身健康的影响逐渐引起了人们的关注。立体视频显示终端大多基于双眼视差原理,为左右眼分别呈现具有视差的图像对,经大脑融合后形成立体图像。目前,大部分关于立体显示设备对人眼生理功能影响的研究单独描述了某类眼部指标的变化,其中调节与集合能力、泪膜及眼表功能等视觉功能的改变显得尤为重要。相关视疲劳症状的出现可能与调节集合的冲突、过量过快的视差变化、视网膜过高的空间频率、立体影像畸变以及使用环境不当等有关。该文结合立体显示的原理,就立体视频显示终端所引起的视疲劳症状和视觉功能改变及其产生的原因进行综述,以期为健康使用立体视频显示终端以及相关症状的临床诊疗提供一定依据。

Abstract:

In recent years, with the development of science and technology, stereoscopic video display terminals have become more and more widely used in many fields. Meanwhile, their influence on the eyes and even the whole body has gradually attracted people's attention. Most stereoscopic video display terminals are based on the principle of binocular parallax. They present image pairs with parallax for the left and right eyes respectively, and form stereoscopic images after brain fusion. At present, most studies about the influence of stereoscopic video display terminals on the physiological function of human eyes describe the changes of a certain type of ocular indicators independently, in which changes in visual functions, such as accommodation and convergence ability, tear film and ocular surface functions are particularly important. The appearance of related visual fatigue symptoms may be due to accommodation-vergence conflicts, excessive and rapid parallax changes, excessive retinal spatial frequencies, stereoscopic image distortion, and improper use environment. This paper introduces the principle of stereoscopic display, summarizes related symptoms and changes in visual functions, and discusses the causes of visual discomfort, in order to provide some bases for the healthy use of stereoscopic video display terminals and the clinical diagnosis and treatment of related symptoms.

Key words: stereoscopic video, visual fatigue, visual function, binocular parallax
