Abstract
A vision testing device and a vision testing program are capable of obtaining a correct test result while reducing an accumulation of fatigue added on one of the eyes of a testee, including: image displays that present a light for suppressing a dark adaptation for both eyes of a testee; and image displays that present a target for an eye (L, R, or both) of the testee so that the target is presented for one of the eyes before the vision testing for the other eye is ended.
