Visual inputs are an important source of information for postural control, This study examines whether such inputs are absolutely necessary for one eye or both eyes, and whether such visual information are more impor tant to left eye or right eye for postural control. The purpose of this study is investigating the comparison of dominant and non-dominant eye-closed condition on dynamic postural balance in healthy young adults. Six health young adults participated in this study. After measured the hold-in-the-card to check the dominant eye, the sample was then measured dynamic postural balance using the Space Balance 3D system. The measur ing programs consisted of a diagnosis plus test, an oblique exercise, and a car avoiding game. To analyze the effect of visual occlusion on dynamic postural balance, this study used the one-way ANOVA. After analyzing, the front of left in the diagnosis and the test was significantly different among in various condi tions, such as an open-eye condition, a closed dominant eye condition, and a closed nondominant eye condition. Average time, effect exercise, and non-effect exercise in the oblique exercise were significantly different among in various conditions (p<.05). The results of this study suggest that the visual information of dominant eye is more effectual information to control postural balance than that of non-dominant eye in healthy young adults.
