Abstract

A visual performance examination device includes an image data obtaining unit that obtains image data of the right eye and image data of the left eye of a test subject who is irradiated with a detection light emitted from a light source; a position calculating unit that, based on the image data of the right eye, calculates first-type relative position data indicating the relative position between the pupil and the corneal reflex of the right eye, and, based on the image data of the left eye, calculates second-type relative position data indicating the relative position between the pupil and the corneal reflex of the left eye; and an evaluating unit that, based on the first-type relative position data and the second-type relative position data, outputs evaluation data about the visual performance of the test subject.
