摘要:
A subjective optometry apparatus (1) includes a light projecting optical system (10) that has a visual target presenting portion (11) for emitting a target light flux and projects a target light flux emitted from the visual target presenting portion toward a subject eye (E), a calibration portion (50) that is disposed in an optical path of the light projecting optical system and changes optical characteristics of the target light flux, an acquisition portion (80) that acquires a near distance objective eye refractive power that is an eye refractive power of the subject eye objectively measured in a near distance viewing state, and a control portion (80) that controls an operation for acquiring a near distance subjective eye refractive power that is a subjective eye refractive power of the subject eye measured in a near distance viewing state, based on the near distance objective eye refractive power.
