摘要： A subjective optometry apparatus includes: a subjective measurer including a light projecting optical system, a corrective optical system including a right-eye corrective optical system and a left-eye corrective optical system, and an optical member for guiding the target light flux corrected by the corrective optical system to an examinee's eye, the subjective measurer subjectively measuring an optical characteristic of the examinee's eye; and an objective measurer including a measurement optical system for emitting measurement light to a fundus of the examinee's eye and for receiving reflected light from the fundus, the objective measurer objectively measuring the optical characteristic of the examinee's eye via the optical member disposed on an optical path of the measurement optical system.

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 subjective optometry apparatus includes a light projecting optical system which projects a target light flux toward an examinee's eye to project a visual target onto the examinee's eye, a calibration optical system which is disposed in an optical path from the light projecting optical system to the examinee's eye and changes optical characteristics of the target light flux, an optical member which guides the target light flux of which the optical characteristics is changed by the calibration optical system to the examinee's eye, a light deflection section being different from the calibration optical system, which includes light deflection members provided in a left and right pair and a driving section which rotationally drives the light deflection members, and deflects the target light flux by rotating the light deflection members, and a control section which controls the light deflection section based on prism information to deflect the target light flux.

摘要： A subjective optometry apparatus includes a light projecting optical system that projects a target light flux to an examinee's eye, a fixed optical element that guides an image of the target light flux to the examinee's eye so as to have an optically predetermined examination length, a calibration optical system disposed in an optical path of the light projecting optical system to change optical characteristics of the examinee's eye, a measurement unit that accommodates the light projecting optical system; a positional information acquiring portion that acquires positional information of the measurement unit, a correction amount setting portion that sets a correction amount for correcting a projection magnification of the target light flux projected to the examinee's eye, based on the positional information, and a correction portion that corrects the projection magnification of the target light flux based on the correction amount set by the correction amount setting portion.
