摘要:
The purpose of the present invention is to provide an apparatus for measuring ocular refractive power, whereby a subjective measurement using an Amsler chart can be easily and appropriately performed. An ocular refractive power measuring apparatus (10) provided with a reflex measurement projection optical system (33) for projecting a measurement light on a main optical axis (O1) toward a fundus (Ef) of a subject eye (E), and a reflex measurement light-receiving optical system (34) for receiving light reflected by the fundus (Ef) from the measurement light traveling along the main optical axis (O1), the ocular refractive power measuring apparatus (10) measuring the ocular refractive power of the subject eye (E) on the basis of the light received by the reflex measurement light-receiving optical system (34). A visual target presentation optical system (31) is provided for presenting, to the subject eye (E) on the main optical axis (O1), an Amsler chart (31v) comprising a grid-shaped pattern as a subjective visual target to be gazed at by a subject to perform a subjective measurement.
