A self-vision tester is a device that allows an examiner to conduct an eye examination on his or her own. It contrasts with the conventional method of measuring vision with the help of an optometrist or ophthalmologist. Self-Vision Tester can be conducted only by manipulating the joystick using a four-point multiple-choice picture or number matching method, and the age range can be used from the lower grades of elementary school with cognitive ability. The inspection time varies depending on the mode, but it has the advantage of being able to inspect in a short time and being easy to install in a narrow space. In particular, the Self Vision Tester PCE model with a touch panel is also available for color blindness, so it is being used at examination centers and driver's license testing centers.
