PROBLEM TO BE SOLVED: To provide a visual mark for a stereoscopic vision inspection realizing the stereoscopic vision inspection accompanying different parallaxes only by single body constitution and contributing to the simplification of an eye inspection operation, the miniaturization of a device and the reduction of costs. SOLUTION: In the visual mark 10 for the stereoscopic vision inspection, separately arranged polarization visual marks composed of the ones for a left eye and the ones for a right eye are visually recognized through polarization spectacles 20L and 20R and the inspection is performed. A visual mark plate main body 10a is provided with the polarization visual marks composed of pair constitution arranged on the left and right for which the interval of each other is continuously changed respectively corresponding to a distance from a center optical axis position, for generating the apparently vertically arranged visual mark images of the pair constitution accompanying the parallax continuously changed corresponding to the distance from a center optical axis. |
