Deep vision tester, three bar visual inspection device, depth motion testerpurpose

The deep vision tester is used to detect the perceptual ability of subjects to distinguish the deep motion of objects, and is one of the indicators of visual function. The deep vision tester adopts the universal three bar method. In the upright three bar system, the two poles on both sides are fixed in a straight line, and the middle pole can move forward and backward at a constant speed. The subject is allowed to sit down 2.5 meters in front of the two fixed poles inside the host, and the lower forehead is stabilized by the bracket. The eyes are fixed on the moving pole through the observation window. When the middle pole moves to be in a straight line with the other two poles, immediately press and hold the remote control switch or response button to enter the test results, and complete one test. In driving adaptability testing, it is generally stipulated that each person is tested three times in a row as one testing cycle, and the ability of the subject to distinguish deep motion of objects is judged based on the average error value.
