Abstract: An apparatus for vision testing comprises a visual test unit (VTU) configured to receive a patients face and perform the vision test on the patient. The VTU includes an internal display configured to generate a light stimulus and a gaze sensor configured to track the eye of the patient. In one aspect, a plurality of VTUs form a system controllable by a common technician to concurrently administer vision tests on different patients. In another aspect, the gaze sensor comprises a camera configured to capture a video of the patients eye displayed to the technician. In another aspect, the VTU is configured to pause testing upon detection of an adverse testing condition such as excessive head tilt or a closed eye. In another aspect, the test display comprises an array of LEDs and a perforated opaque screen to provide sufficient luminance.
