The present study was designed to investigate the influence on body sway in standing of changes in visual information by view and saccade stimulation. Subjects were seven healthy adults. In Experiment 1, participants maintained standing with legs together on a center of foot pressure platform with 1) central vision, and 2) periphery vision under eyes open conditions for thirty seconds. The central vision value was significantly decreased compared to the periphery vision. This result implies as the influence of the change of visual information by saccadic eye movement. In Experiment 2, participants maintained standing with legs together and tandem on a center of foot pressure platform with 1) natural view, and 2) saccade stare under eyes open conditions for ten seconds. There was no significant difference between natural view and saccade stare under either condition. The cause of the increased sway was not the influence of the change of vision by saccadic eye movement, which suggests a decrease in the relative quality of information of objects in periphery vision.
