Zusammenfassung:A subjective optometry apparatus includes subjective measurement unit for subjectively measuring an optical characteristic of a subject eye, the subjective measurement unit including a calibration optical system that is disposed in an optical path of a light projecting optical system projecting a visual target luminous flux toward the subject eye and changes an optical characteristic of the visual target luminous flux. The subjective optometry apparatus includes objective measurement unit for objectively measuring the optical characteristic of the subject eye, the objective measurement unit including a measurement optical system that emits measurement light to a fundus of the subject eye and receives reflected light of the measurement light. The subjective optometry apparatus includes controller for objectively measuring the optical characteristic of the subject eye by the objective measurement unit while the optical characteristic of the subject eye is subjectively measured by the subjective measurement unit.
