Claim:
1. An ophthalmologic apparatus comprising: a refractive power application unit configured to be capable of changing refractive power applied to a subject's eye; a storage unit configured to store at least spherical power, degree of astigmatism, and astigmatic axis angle as a measurement value of eye refractive power obtained by a measurement performed for the subject's eye in a past; a calculator configured to obtain one or more refractive values including equivalent spherical power based on the measurement value; and a control unit configured to control the refractive power application unit to selectively apply the measurement value and the one or more refractive values different from the measurement value to the subject's eye to which a same visual target is being presented in response to input of an instruction to change refractive power applied to the subject's eye.
