The Effects of Recovery Method and Refractive Status on the Recovery Process of Visual Fatigue

摘要

The aim of this study was to investigate the effects of recovery method and refractive status on the generation and recovery progress of visual fatigue in the dynamic visual search tasks. A human factor experiment was conducted, in which a two-factor mixed design was adopted (2 recovery method x 2 refractive status). 31 subjects participated in this study. The results indicated that the refractive error subjects' fatigue level was always higher than that of normal vision subjects when conducted dynamic visual search tasks. Compared to eye massage, using eye drops could lead to a quick recovery at the initial stage, then slowed down. The recovery trend of using eye massage was closer to a linear trend.
