An ophthalmologic apparatus includes a first light source configured to emit a first measuring beam, a second light source configured to emit a second measuring beam having a center wavelength longer than that of the first measuring beam, a third light source configured to emit a third measuring beam having a center wavelength shorter than that of the first measuring beam, a first acquisition unit configured to obtain a first image of the subject's eye by using the return beam of the second measuring beam from the subject's eye, aberration of which has been corrected by a correction unit, and a second acquisition unit configured to obtain an anterior eye portion image of the subject's eye to be used for alignment, by using a return beam of the third measuring beam from the subject's eye.
