Purpose: The purpose of this study was to obtain the fundamental data of dynamic visual acuity and dynamic stereoacuity.
Methods: The subjects were 20 athletes (high school baseball player) and 40 nonathletes (20 male, 20 female). We assessed static visual acuity, dynamic visual acuity, static stereoacuity and dynamic stereoacuity using rotating mirror projection system and computer program.
Results: Three groups had similar static visual acuity and static stereoacuity. On the other hand, the dynamic visual acuity and dynamic stereoacuity showed statistically significant differency. The mean dynamic visual acuity for athletes was 174.80?8.70 deg/sec, 137.10?6.54 deg/sec for male nonathletes and 111.59?5.40 deg/sec for female nonathletes. The mean dynamic stereoacuity for athlets was 234.55?9.64, 249.05?.86 for male nonathletes and 247.10?4.89 for female nonathletes. The group of athletes had better dynamic visual acuity and dynamic stereoacuity.
Conclusions: If the result of this study apply to sports, it will be very useful to improve sports performance.
