This project was conducted in order to examine visual of the elite athletes and compared the different visual abilities between elite and non-elite athletes by employing seven different visual ability tests. After administring the visual ability tests, important visual characteristics which might have important role to become elite athetes were identified. In the second experiment, two different visual abilities(dynamic visual acuity and depth perception) selected in order to examine the visual training effect for baseball hitting performance for these visual abilities had shown the most relevant visual characteristics for batting performance in the first experiment. The results revealed there were different visual characteristics between athletes in different sports (archery, shooting, ice hockey, baseball), and elite and non-elite athletes. The results also found specific relationship between certain visual characteristics and the sports events. The results of the second experiment revealed the subjects in the experiment group(visual training group) improved their visual abilities significantly through specially designed visual training in the laboratory and the improved visual abilities had positive effect on batting performance in the field.
