OPHTHALMIC DEVICE

An ophthalmic device includes an anterior ocular segment photographing unit (50), a fixation target display unit, and a control unit (71). The anterior ocular segment photographing unit captures an anterior ocular segment image of a left eye and a right eye of the subject. The fixation target display unit displays a fixation target with respect to the at least one of the left eye and the right eye of the subject. The control unit measures an eye position of the at least one of the left eye and the right eye of the subject by processing the anterior ocular segment image captured by the anterior ocular segment photographing unit. The control unit generates eye position state information indicating a state of the eye position of the subject, based on measurement results of the eye position at at least two timings including a post-switch timing and a pre-switch timing.
