摘要： An eye refractive power measurement apparatus includes: a measuring optical system for projecting measurement light onto a fundus of an examinee's eye, and causing a two-dimensional imaging device to capture the measurement light to be reflected from the fundus as a plurality of target pattern images at different distances from a measurement optical axis; a light deflecting member 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 an eye refractive power of the examinee's eye based on a target pattern image to be captured by the two-dimensional imaging device.

摘要： 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 examinee's eye; a light deflecting member arranged at a position, which is not conjugated with a pupil of the examinee's 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.
