An eye refractive power measurement apparatus measures both eye refractive powers in cases where a pupil is small and large in diameter with ease. This apparatus includes: a measuring optical system causing an imaging device to capture a ring-shaped image based on measurement light reflected from a fundus of an examinees eye a light deflecting member arranged at a position, which is not conjugated with a pupil of the examinees eye, on an optical path of the measuring optical system a rotor causing the light deflecting member to rotate about an optical axis of the measuring optical system and an eccentricity amount changer changing an amount of eccentricity of the measurement light, which is rotated eccentrically on a surface of the pupil, with respect to a center of the pupil, in order to change a region, where the measurement light passes, on the surface of the pupil.
