PURPOSE: To automatically and selectively test plural defects of visual sensation by discriminating visual sensation ability by recording the response of a reagent to answer through the user interface of a keyboard, etc., while watching basic characters or graphics projected on a video screen. CONSTITUTION: As for a vision test, the visual acuity level of a testee is evaluated by successively reducing the size of series of images so as to watch series of video images 12 displayed on a screen 14 from a fixed distance through an eyepiece 26 by the testee. As for color discrimination test, series of color bars 44a-44d or the like are displayed on the screen 14. The testee rearranges the color bars or the like arranged at random in the order of color changes form a sight examination system 8 based on the colors sensed by his own eyes. As a result, it is determined whether the reagent achieves a required color discrimination ability level or not. As for perspective sensation test, series of three different visual images are displayed on the screen repeatedly until the testee is satisfied with the location of left and right objects on the screen in the equal distance in depthwise direction, and the error of a perspective gap is detected.
