Purpose : This study was intended to investigate the effect of distance on changes in visual function and fatigue when playing console games.
Methods : Thirty male and female subjects with an average age of 24.56 ± 1.67 years without eye disease were tested. A fatigue survey was conducted before and after the console game, and changes in visual function were observed by examining amplitude of accommodation, near point of convergence, and accommodative facility. The game was played for 30 minutes, Nintendo was used at a short distance, and the game was played on a TV at a distance, and the difference according to viewing distance was analyzed using a paired t-test.
Results : In terms of fatigue, when comparing changes after close and long distance games among 28 items, only the sleepy item showed a significant difference with TV showing a higher score by 0.63 points. In terms of visual function, monocular amplitude of accommodation, near point of convergence, and accommodative facility decreased in near distance games. After the distance game, there was a statistically significant decrease in the near point of convergence and accommodative facility, but no statistically significant change was observed in the amplitude of accommodation.
Conclusions : Therefore, it is considered that fatigue and changes in visual function caused by console games show a tendency regardless of distance.
