An optotype presenting apparatus capable of performing a stereoscopic vision test with accuracy comprises a display, display control means, and a polarization optical member comprising regions having a constant width W, characterized in that the display control means displays first optotypes with a deviation amount in a lateral direction therebetween being an odd multiple of the width W, so that the first optotypes are presented as a reference optotype having a predetermined float or sink amount with respect to a display surface, and that in order to form a fusion optotype having a float or sink amount with respect to the reference optotype which is approximate to an intended parallax, second optotypes are displayed such that a deviation amount therebetween is an odd multiple of the width W and a parallax of the fusion optotype with respect to the reference optotype is approximate to the intended parallax.
