ABSTRACT
PURPOSE:
To evaluate changes in corneal and ocular high-order aberration, ocular fatigue, and tear break-up time (TBUT) before and after playing computer games and the correlations among the variables.METHODS:
Thirty-nine normal healthy subjects played computer games for 1 hour. Ocular fatigue was evaluated with a questionnaire, TBUT was measured with slit-lamp biomicroscopy, and high-order aberrations were measured with a KR-1W aberrometer (Topcon Medical System, Inc., Tokyo, Japan) in each subject before and after playing computer games. The right eye was used for statistical analyses.RESULTS:
Subjective ocular fatigue (expressed as the interview score) increased from 4.23 +/- 5.35 to 12.05 +/- 8.68 after playing games (p < 0.001) and TBUT decreased from 8.03 +/- 6.43 sec to 4.90 +/- 3.31 sec (p < 0.001). Ocular high-order aberrations in the 4 mm and 6 mm zones were not significantly changed before and after playing games (p = 0.150, p = 0.202, respectively). However, corneal high-order aberrations in the 4 mm and 6 mm zones were significantly increased after playing computer games (p = 0.002, p = 0.002, respectively). Changes in TBUT, interview score, and corneal high-order aberration were not correlated with each other.CONCLUSIONS:
Playing computer games increased corneal high-order aberrations as well as subjective ocular fatigue and TBUT.
