Zusammenfassung: | A subjective optometry apparatus includes an optometry unit having an optical member, being located in front of a subject eye, and changing optical characteristics of a target light flus with using the optical member, and a measurement optical system that has a light projecting optical system for applying measurement light emitted from a measurement light source to a fundus of the subject eye through the optometry unit, and a light receiving optical system in which a detector receives reflected light of the measurement light reflected on the fundus of the subject eye through the optometry unit, and that objectively measures the optical characteristics of the subject eye. An optical axis of the measurement optical system is set to be off-axis from an optical axis of the optical member in the optometry unit. |
