On the other hand, in order to observe an eye fundus portion of the eye (E) to be examined, when the frame is moved to within a second region to leave the eye (E) to be examined, the stereo angle converting portion and the color temperature converting element (61) are disposed on the right and left optical axes (L1 and L2).
