摘要:
A subjective optometry apparatus includes a light projecting optical system that projects a target light flux to an examinees eye, a calibration optical system that is disposed in an optical path from the light projecting optical system to the examinees eye, and changes optical characteristics of the target light flux, an optical element that guides the target light flux of which the optical characteristics is changed by the calibration optical system to the examinees eye, and a correction portion that corrects distortion of the target light flux caused by the target light flux passing through an optical path deviated from an optical axis of the optical element. The target light flux passes through the optical path deviated from the optical axis of the optical element to be guided to the examinees eye. The subjective optometry apparatus subjectively measures optical characteristics of the examinees eye using the target light flux guided to the examinees eye.
