Abstract: A refractive property measurement apparatus to measure refractive properties of an eye includes: a disk provided with a first pinhole and a second pinhole that transmit light rays while narrowing them; a light emitting unit that emits a first light ray and a second light ray from different positions on a surface of the disk, so that light rays passed through the first pinhole and the second pinhole enter the eye; and a processing unit determines refractive properties of the eye from information of positions on a retina of the eye where the first light ray having passed through the first pinhole and the second light ray having passed through the second pinhole reach. The first pinhole includes a first optical element that transmits the first light ray, and the second pinhole includes a second optical element that has transmission characteristics of transmitting the second light ray.
