Abstract: A subjective optometry apparatus has a projection optical system including a visual target presenting portion and an optical member to project a target light flux toward a subject eye, and causing the target light flux to be incident on the optical member with a deviation of the incident target light flux from an optical axis of the optical member, a housing accommodating the projection optical system, a presentation window for emitting the target light flux from the inside of the housing to the outside thereof, an eye refractive power measurement unit provided outside the housing, and holding means integrally connecting the housing to the eye refractive power measurement unit to hold the eye refractive power measuring unit. When using the eye refractive power measuring unit, a distance from the presentation window to the eye refractive power measurement unit in an optical path is equal to or less than 180 mm.
