Abstract
The ophthalmological device of an embodiment includes an optical system for inspection, a display, a subject's eye position acquiring unit, and a control unit. The optical system for inspection includes a photographic optical system for photographing an eyeground of the subject's eye. The subject's eye position acquiring unit acquires a three-dimensional position of the subject's eye. The control unit acquires information on positional displacement of the optical system for inspection with respect to the subject's eye on the basis of the three-dimensional position to cause a screen of the display to display two alignment index images to be varied in position with respect to a reference position of alignment preset in the display in a pseudo manner, in accordance with the information on positional displacement.
