There is provided a subjective eye refracting power measurement apparatus which measures a refracting power of a subject eye. The apparatus includes a projection optical system which projects a visual target light flux toward the subject eye to form a visual target on a fundus of the subject eye a correction optical system which changes a refracting power thereof a relay optical system which relays a light flux passing through the correction optical system and to form an image of the correction optical system in front of the subject eye a deviation detector which detects a positional deviation of the image of the correction optical system with respect to the subject eye and a correction unit which optically corrects a formation position of the image based on a detection result by the deviation detector such that the image is formed in front of the subject eye.
