WIPO Patent Application WO/2021/065247

A1

Provided is a binocular vision function measurement method including: a target presentation step for presenting on a single portable display screen to a subject a right-eye image to be viewed by the right eye of the subject and a left-eye image to be viewed by the left eye of the subject; a presentation control step for relatively changing the presentation positions of the right-eye and left-eye images; a timing sense step for sensing timing at which the subject cannot fuse the right-eye and left-eye images while changing the presentation positions; and a parameter value computation step for computing a predetermined parameter value about the binocular vision function of the subject according to the relative position relationship of the right-eye and left-eye images at the sensed timing.
