ABSTRACT:
An eye refractive power measurement apparatus by which an examiner can properly check reliability of a measurement result while time and effort of the examiner are saved. The eye refractive power measurement apparatus for measuring eye refractive power of an examinee's eye has a measurement optical system for projecting a measurement target onto a fundus of the eye to pick up a fundus reflection image by a two-dimensional image-pickup element, a storing device which stores the picked-up fundus reflection image as a measurement image, a display device, a measurement condition judging device which makes a judgment as to whether or not the stored measurement image satisfies a predetermined measurement condition, and a first display control device which controls the display device to display the stored measurement image when the measurement condition judging device judges that the measurement condition is not satisfied.
