An ocular refractive-power measuring device includes: an alignment unit effecting alignment between a vertex of a cornea and a device body on the basis of corneal reflecting light; a refractive power measuring unit measuring the refractive power of an eye to be examined on the basis of the shape of a pattern light rays for ocular refractive power measurement reflected from a fundus of the eye to be examined; a storage unit storing the shape of the pattern light rays for ocular refractive power measurement; and an eclipse direction detecting system detecting the presence or absence of an eclipse in the pattern light rays due to a pupil of the eye to be examined on the basis of the shape of the pattern light rays stored in the storage unit, and detecting a direction of the eclipse. This alignment unit is arranged to effect adjustment of alignment between the pupil of the eye to be examined and the device body by adjustably moving the position of the device body on the basis of a result of detection by the eclipse direction detecting system.
