Abstract
An ophthalmic device (1) of the present invention has an optical head (2) including a light projection optical system (21) that projects light onto a subject eye (E), a light reception optical system (22) that receives light from the subject eye (E), and a fixation lamp (23) for guiding a line-of-sight direction of the subject eye (E), and a turning drive unit that turns the optical head (2) in a horizontal direction while maintaining positional relationships between the light projection optical system (21), the light reception optical system (22), and the fixation lamp (23). The turning drive unit is composed of a rotational drive unit (4) that rotates the optical head (2) in the horizontal direction and a horizontal drive unit (3) that moves the optical head (2) in the horizontal direction.
