Claim 0:
1. An ophthalmologic apparatus, comprising:
a refractive power measurement optical system including a first focusing element capable of changing a focal position, and configured to project first light onto a subject's eye and to detect returning light of the first light from the subject's eye via the first focusing element;
a fixation projection system configured to project a fixation target onto the subject's eye;
an inspection optical system including a second focusing element capable of changing a focal position in conjunction with the first focusing element, and configured to perform a predetermined inspection in which second light is projected onto at least the subject's eye via the second focusing element; and
a controller configured to control the first focusing element and the second focusing element based on a detection result of the returning light of the first light. the returning light being obtained by performing provisional measurement using the refractive power measurement optical system in a state where the fixation target is projected onto the subject's eye, and to perform refractive power measurement using the first light in a state of promoting a fogging of the subject's eye by controlling the fixation projection system after performing the predetermined inspection using the inspection optical system.
