It is known that most people have a dominant eye, even though each of their two eyes in isolation may provide equal vision. In this study, 600 Korean male and female subjects aging from 11 to 78 were selected to investigate the various statistics about eye dominance( whether the left or right eye is dominant} in Korean and their employment characteristics of preferred eye in sighting diverse things. A simple sighting test was applied such that subjects are requested to aim a distance target through small hole in B4 sized paper with both eyes open. The dominant eye was determined by alternate occlusion: when viewing with the dominant eye into the hole is aligned with the target, whereas when viewing with the other eye into the hole appears offset to one side. The descriptive statistics showed that 83.7% and 16.3% were right and left eye dominant respectively. Moreover, various statistical analysis revealed that general tendency of eye dominance was varied by age, gender, hand dominance and visual acuity. It was thus found from these results that people sighting their eyes differently depending on the eye dominance when they sight things.
