Abstract: A subjective optometry apparatus includes a subjective measurement portion which subjectively measures optical characteristics of an subject eye, an objective measurement portion which objectively measures optical characteristics of the subject eye, a control portion which causes the objective measurement portion to objectively measure the optical characteristics during the measurement by the subjective measurement portion, and a display control portion which performs a control to display an eye diagram representing the subject eye and an imaging position of a target light flux incident on the subject eye. The display control portion performs a control to display the imaging position based on the objectively measured optical characteristics.

Abstract: An ophthalmic device includes an anterior ocular segment photographing unit, a fixation target display unit, and a processor. The anterior ocular segment photographing unit captures an anterior ocular segment image of at least one of a left eye and a right eye of a 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 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. The processor generates eye position state information, which indicates a state of the eye position of the subject, based on measurement results of the eye position at least two timings including a post-switch timing and a pre-switch timing.
