摘要： 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.

摘要： An optometry apparatus includes: an optical characteristic measurement device configured to measure an optical characteristic of right and left subject eyes in a both-eye opened state by projecting a visual target onto the subject eyes; an anterior ocular segment acquisition device configured to acquire anterior ocular segment images of the right and left subject eyes by the optical characteristic measurement device during the measurement of the optical characteristic of the subject eye in the both-eye opened state; and a controller configured to execute: an analysis instruction for performing analysis processing on the anterior ocular segment images acquired by the anterior ocular segment acquisition device to acquire both-eye opened state information; a determination instruction for determining whether the both-eye opened state information acquired by the analysis instruction is favorable or not, to acquire determination information; and an output instruction for outputting the determination information acquired by the determination instruction.

摘要： 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.

摘要： 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.
