Abstract

A subjective optometric apparatus includes: a projection optical system that includes a target presenting unit configured to emit a target light flux, the projection optical system being configured to project, onto an examinee's eye, the target light flux emitted from the target presenting unit; a housing configured to accommodate the projection optical system; a presentation window configured to project the target light flux onto the examinee's eye by transmitting the target light flux emitted from the projection optical system and outputting the target light flux from an inside of the housing to an outside of the housing; and an observation unit configured to observe, via the presentation window, a positional relationship between the examinee's eye and an eye refractivity measuring unit configured to change an optical property of the target light flux output from the inside of the housing to the outside of the housing.
