ABSTRACT:
An opthalmologic apparatus having a setting part configured to acquire position information of a first examining part at the time of execution of a first examination and set a movable range of a second examining part in a direction of a second working distance based on the position information and distance information. This opthalmologic apparatus controls so that an examining unit moves within the movable range set based on the position information of the first examining part and the distance information when an examination by the examining unit is switched from the first examination to a second examination. Accordingly, it is possible to set an accurate movable range with respect to the position of the eye of a subject, and it is also possible to increase safety by preventing the examining part from coming in contact with the subject.
