Research Abstract

Baseball players could achieve high DVA (Dynamic Visual Acuity) with significantly faster eye movement at shorter latencies than non-players. There was no difference in the ability to perceive moving object's images projected onto the retina between the baseball players and non-players. These results suggest that the better DVA of baseball players is primarily due to a better ability to track moving objects with their eyes rather than to improved perception of moving images on the retina.
