PROBLEM TO BE SOLVED: To provide a binocular function measuring method which is suitable for highly precisely measuring binocular function while reducing cost burden.SOLUTION: The binocular function measuring method by utilizing a stationary three-dimensional video monitor includes: a parallax image display step of displaying left and right parallax images at a predetermined measurement start position on a display screen when a measurement item is designated； a parallax image display changing step of relatively changing the left and right parallax images in accordance with the designated measurement item； a timing detecting step of detecting a timing when the subject viewing the left and right parallax images at a position distant by a predetermined distance from the display screen cannot fuse the left and right parallax images； and a measurement value calculating step of calculating a measurement value of the designated measurement item based on the predetermined distance and a difference between the left and right parallax images defined at the detected timing.
