An ophthalmic device is configured to select a bright spot image Ta corresponding to a light beam reflected by a cornea, as opposed to intraocular lens reflection ghost image Ta, Tb, Tc for example, on the basis of a positional relationship between a first bright spot image, cornea centre bright spot image Ta formed from a plurality of bright spot images Ta, Tb, Tc corresponding to a first projection light beam, and a second bright spot image 221a,221b corresponding to a second projection light beam, and to calculate a state of alignment between the subject eye and a measuring unit using the selected bright spot image Ta. The cornea centre bright spot image Ta is selected over cornea bright spot images Tb,Tc due to it being flanked by both upper and lower associated bright spot images and is selected over intraocular lens reflection ghost image Ta due to it being closer to the centre point between cornea reflection bright spot images 221a,221b. |
