The present invention relates to an apparatus for the precision measurement of the optical characteristics of the eye and the shape of the cornea of the eye. An object of the present invention is to provide an optical characteristic measuring apparatus capable measuring the optical characteristics of an irregular astigmatism component. An illuminating optical system illuminates a minute region on the retina of the eye with light rays emitted by an illuminating light source, a reflected light guiding optical system guides reflected light rays reflected from the retina of the eye to a light receiving device, a converting device converts the reflected light rays into at least seventeen light beams, a light receiving device receives the plurality of light beams from the converting device, and an arithmetic unit determines the optical characteristics of the eye and the shape of the cornea on the basis of the inclination of the light rays determined by the light receiving device.
