In order to reduce a tester's workload When the device main body of the vision testing device is mounted on a testee's head, there is provided a head mount-type vision testing device, which is a head-mount type vision testing device mounted on a testee's head, including: a device main body having display devices 12L and 12R for displaying a visual target for the testee and imaging deviceS 16L and 16R for imaging eyeballs 8L and 8R of the testee； a mounting fixture for mounting the device main body on the testee's head； and a controller 30 that displays images of the eyeballs 8L and 8R imaged by the imaging devices 16L and 16R on the display devices 12L and 12R, so that the testee can recognize a positional displacement state of the eyeballs 8L and 8R caused by a positional displacement of the device main body mounted on the testee's head using the mounting fixture.
