Abstract: A controller of an ophthalmic apparatus finely drives and roughly drives a drive unit of an optometry unit. In a case where a tilt operation of tilting the operation stick within a predetermined range is detected by an operation detection unit, the controller finely drives the drive unit by controlling the drive unit in response to the detected tilt operation, and finely changes a position of the optometry unit. In a case where at least one of a tilt operation of tilting the operation stick over a predetermined range and an operation of a rough movement operation unit is detected by the operation detection unit, the controller roughly drives the drive unit by controlling the drive unit in response to the detected operation, and roughly changes the position of the optometry unit.
