摘要:
A subjective optometry apparatus includes a light projecting optical system that has a visual target presenting portion for emitting a target light flux and projects a target light flux emitted from the visual target presenting portion toward a subject eye, a calibration portion 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 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 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.
