1. An ophthalmologic device to be coupled to a correcting device configured to correct a visual function of subject eyes, the correcting device including a right-left pair of two examination windows arranged along respective optical axes and a right-left pair of arrangement mechanisms that each arrange one or more first optical elements between the two examination windows, the two examination windows include a right-left pair of first examination windows which are eyepiece windows that face each subject eye and are arranged on a first side surface of the correcting device and a right-left pair of second examination windows arranged on a second side surface of the correcting device opposite to the first side surface of the correcting device, the correcting device further including a right-left pair of openings on the second side surface of the correcting device that each surround a corresponding second examination window, the ophthalmologic device comprising:
a coupling member configured to be detachably coupled to each of the openings on the second side surface of the correcting device that each surround a corresponding second examination window, the openings being provided on the second side surface of the correcting device on a side opposite to the first side surface of the correcting device that is configured to face each subject eye;
a second optical element arranged at a position facing the second examination window opposite to the first examination window which is the eyepiece window for each subject eye, in a case where the coupling member is coupled to the opening on the second side surface of the correcting device, the second optical element configured to branch a second optical path from a first optical path along the optical axes; and
an objective measuring system arranged on the second optical path and configured to acquire ocular characteristics of each subject eye wherein a center of the first examination window and a center of the second examination window are arranged along a same line.
