Effects of Virtual Reality Head-mounted Displays on Oculomotor Functions

Purpose: Three-dimensional (3D) video games played using virtual reality head-mounted displays (VR-HMDs) are becoming increasingly popular. However, the use of this technology may lead to visual symptoms and discomfort by disrupting normal linkage between accommodation vergence systems. This study aimed investigate effect playing 3D VR-HMDs on different oculomotor functions (i.e., and/or system parameters) quantify associated with VR-HMD technology. Methods: Twenty –six male female young adults (age range 19–27 years) binocular vision completed study. Different clinical accommodative measurements were collected before after a for 45 minutes. In addition, visual- non–visual-related measured game sessions standardized Simulator Sickness Questionnaire. Results: The majority parameters—including negative relative accommodation, accuracy, monocular facilities—were significantly affected games. With respect measurements, horizontal fusional at near facility test outcomes sessions. Significant increments in types nonvisual) also observed system. Conclusions: Playing systems can deterioration certain systems). Players be expected experience eyestrain just minutes playing.
