Visua function is regarded as important ability to kendo players. In order to clarify the effect of this visual function over kendo players of different level, we used sorts vision test to measure eight parameters, which include SVA (Static Visual Acuity), KVA (Kinetic Visual Acuity), DVA (Dynamic Visual Acuity), CS (Contrast Sensitivity), OMS (Ocular Motor Skill), DP (Depth Perception), VRT (Visual Reaction Time) and E/H (Eye/Hand Coordination).
For each parameter, we paritioned play level into 3 groups (higher, medium and lower group)depending on the player's capability. By means of statistical analysis and comparison of each experimental result, we conclude that.
higher group is superior to the others on SVA, KVA and E/H values. In addition, higher group's value is higher than those of medium group and lower group on CS and DP parameter, respectively.
It is concluded that, difference of skill of kendo players is involved with that of depth perception to sense space and distance, and coordination of eye with hand of the players.
