摘要:
An eye refractive power measuring apparatus includes: a measuring part configured to project measurement light onto a fundus of an examinees eye and measure refractive power of the eye based on reflection light of the measurement light from the fundus a fixation target presenting part configured to present a fixation target to the eye a drive part configured to move a presenting position of the fixation target and a control part configured to control the drive part to move the presenting position from far distance to near distance, the apparatus being configured to measure the eye refractive power in at least a far position and a near position, wherein the control part controls the drive part to change a control amount thereof based on a change in measurement results of the eye refractive power while the fixation target is moved from the far distance to the near distance.
