Abstract

Background: Prolonged 2D screen–based nearwork activities can induce visual fatigue and mental fatigue, leading to a decline in cognitive performance. Ocular accommodation–convergence activity is a key mechanism contributing to this condition. Virtual reality (VR) technology has the potential to be used as an intervention by eliminating the need for accommodation–convergence. Objective: To analyze the effect of eliminating ocular accommodation–convergence using a VR device on mental fatigue parameters within individuals during nearwork activities. Methods: This study employed an intra-individual crossover design involving 20 healthy male subjects aged 18–25 years. Each subject underwent two conditions: (1) a 2D screen–based Pauli Test and (2) a 3D VR–based Pauli Test. Mental fatigue parameters were assessed using objective multi-biomarkers, including Pauli Test performance, pupil diameter, P300 ERP latency and amplitude, and EEG waves (frontal theta, parietal and occipital alpha). Statistical analysis was performed using a Linear Mixed-Effects Model (LMEM). Results: Duration and time factors had a significant effect on pupil diameter reduction (p<0.001) and P300 latency prolongation (p=0.034), indicating the progression of mental fatigue with increasing nearwork duration. No significant differences were found between 2D and 3D VR conditions in alpha and theta wave parameters or P300 amplitude. However, cognitive performance, as measured by the Pauli Test, showed a significant improvement under the VR condition, which was able to maintain and enhance cognitive performance compared with the 2D screen condition (p=0.017). Conclusion: A 3D VR–based intervention eliminating accommodation– convergence during nearwork activities does not inhibit the neurophysiological development of mental fatigue, but it provides benefits in improving cognitive performance. VR has the potential to serve as an alternative nearwork medium without significantly increasing or decreasing the risk of mental fatigue compared with 2D screen–based media.
