To provide a method and a meter to measure refracting power distribution of a subject eye by irradiating thin light flux and measuring light reflected by the eyeground through a specific pattern.

This refracting power meter has a light projecting optical system with an aperture for irradiating the thin light flux to the eyeground and the cornea of the subject eye and a light receiving system to guide the reflected light to a light receiving element through the specific pattern (multiple ring pattern, or the like) placed on a position corresponding to the cornea. Refracting power is calculated at every positions of the cornea using measurement values detected by the light receiving element to display a condition of refracting power distribution on the cornea.
