1. An ophthalmologic apparatus comprising:
a subjective measurement optical system configured to measure a subjective refractive value of a subject eye;
an objective measurement optical system configured to measure objective refractive characteristics of the subject eye; and
a controller configured to control the subjective measurement optical system and the objective measurement optical system,
wherein the controller is further configured to perform measurement of the objective refractive characteristics of the subject eye by the objective measurement optical system and perform objective monitoring to monitor objective measurement information obtained by the measurement of the objective refractive characteristics during a weakest power test in which a weakest point is being obtained by the subjective measurement optical system, a maximum visual acuity value or a set predetermined visual acuity value being readable from the weakest point.
