Abstract: A target presenting apparatus includes: a display for emitting a target light flux; a concave mirror for receiving the target light flux in such a manner as to displace the target light flux from an optical axis thereof; a housing for accommodating the concave mirror and the display therein; and an optical member, placed in the housing, for guiding the target light flux from the inside to the outside of the housing to present a target to an examinee.

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.

Abstract: An optometry apparatus includes: a housing accommodating a concave mirror disposed on a reference axis; and a display disposed outside the housing and out of the reference axis for projecting a target light flux onto the concave mirror. The concave mirror is configured to reflect the target light flux output from the display toward an examinee's eye along the reference axis.

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.
