Ophthalmic device

An ophthalmic device comprising:

• a measurement optical system which includes a light-emitting optical system including a light source configured to emit light beam in a spot shape onto a fundus of a subject eye and a light-receiving optical system including a light receiving element configured to receive reflected light from the fundus of the subject eye;
• an arithmetic device configured to calculate an eye refractive power of the subject eye based on an output of the light receiving element;
• a beam deflecting member arranged in an optical path of the measurement optical system and configured to deflect the beam emitted from the light source;
• and
• a driving device configured to drive the beam deflecting member so that the beam emitted from the light source is scanned in a ring shape onto the subject eye;
• wherein
• the beam deflecting member is disposed so that traveling directions of the beam emitted from the light source intersect with each other between the subject eye and the beam deflecting member when the beam deflecting member is driven by the driving device.
