Abstract: An ophthalmic device includes a detecting unit configured to detect a relative position of a subject eye relative to a ocular characteristic acquiring unit, a provisional alignment controlling unit configured to drive a relatively-moving unit based on a detection result by the detecting unit and perform provisional alignment, a re-detecting unit configured to repeatedly detect the relative position after completion of the provisional alignment, a determining unit configured to determine whether the ocular characteristic acquiring unit has been brought closer to the subject eye by a distance greater than or equal to a predetermined threshold value by the provisional alignment based on the detection result, and an operation mode selecting unit configured to select either one of a normal mode and a quick mode as an operation mode for alignment and acquisition of the ocular characteristic based on a determination result by the determining unit.
