Ophthalmic device

An ophthalmic device that performs an examination of a visual function of a subject, the ophthalmic device comprising:

• an anterior ocular segment photographing unit that captures an anterior ocular segment image of at least one of a left eye and a right eye of the subject;
• a fixation target display unit that displays a fixation target with respect to the at least one of the left eye and the right eye of the subject;
• and
• a processor that controls the ophthalmic device,
• wherein
• the processor
• 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, and
• generates eye position state information based on measurement results of the eye position of an examination target eye at at least two timings including a post-switch timing and a pre-switch timing, the eye position state information indicating a state of the eye position of the subject, the post-switch timing being a timing after a display switch timing at which display and non-display of the fixation target with respect to the at least one of the left eye and the right eye of the subject is switched, and the pre-switch timing being a timing before the display switch timing.
