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.
