Abstract
Disclosed is a binocular visual simulator for correcting eyeball aberration by using adaptive optics to form a chart image on both eyes. The binocular visual simulator includes; a chart-projecting unit for producing a chart light; an adaptive optics element for changing the chart light in accordance with wavefront aberration measured for both eyes; a beam splitter for dividing the changed chart light into two chart lights; a left eye correction unit for changing the divided chart light in accordance with wavefront aberration of the left eye so that the chart light is focused on a retina of the left eye; and a right eye correction unit for changing the divided chart light in accordance with wavefront aberration of the right eye so that the chart light is focused on a retina of the right eye.
