ABSTRACT:
There is disclosed an ophthalmic apparatus including a detection unit which detects a vision fixation state of an eye to be examined, a projection unit which projects a fixation mark onto a fundus of the eye, and a fixation mark control unit which controls the projection unit. The projection unit includes a changing unit which changes a fixation mark to be projected onto the fundus, and when a vision fixation state detected by the detection unit does not satisfy a predetermined criterion, the fixation mark control unit controls the changing unit to change a fixation mark to be projected onto the fundus.
