Claim One:
1. An eye refractive power measurement apparatus comprising: a measuring optical system for projecting measurement light, from a light source, onto a fundus of an examinee's eye, and causing a two-dimensional imaging device to capture the measurement light reflected from the fundus as a measurement image including a plurality of ring images simultaneously formed at different distances from a measurement optical axis, the plurality of ring images including at least a first ring image and a second ring image, the second ring image being outside the first ring image; a light deflecting member for deflecting the measurement light with respect to the optical axis, the light deflecting member being arranged at a position out of a conjugate position with a pupil of the examinee's eye on an optical path of the measuring optical system; a rotor for rotating the light deflecting member about an optical axis of the measuring optical system to allow a plurality of pattern light beams to be eccentrically rotated on the pupil; and a calculator for measuring a plurality of eye refractive powers of the examinee's eye based on the plurality of ring images simultaneously formed on the two-dimensional imaging device, the calculator configured to measure a first eye refractive power at least based on the first ring image and to measure a second eye refractive power at least based on the second ring image.
