Patent ID: 7309126

Claim:
An eye characteristic measuring apparatus, comprising: a first illumination optical system having a first light source section for emitting a first light flux of a first wavelength, and for illuminating an eyeground of an eye to be examined with the first light flux from the first light source section; a first light receiving optical system having a first light receiving section for forming a first received light signal from a received light flux, and for guiding a light flux reflected and returned from the eyeground of the eye to be examined to the first light receiving section; a second light receiving optical system having a second light receiving section for forming a second received light signal including information of an anterior eye part from a received light flux, and for guiding a second light flux including information relating to a feature portion of the anterior eye part of the eye to be examined to the second light receiving section; a coordinate setting section for forming a coordinate system based on a feature signal included in the second received light signal and corresponding to an image of the feature portion of the anterior eye part of the eye to be examined, and for correlating measurement data obtained based on the first received light signal with the coordinate system; a measurement section for obtaining optical characteristics including refractive power of the eye to be examined based on coordinate values in the coordinate system, the coordinate values into which the measurement data are obtained based on the first received light signal of the first light receiving section are converted; and a display section for displaying the optical characteristics of the eye to be examined obtained by the measurement section in relation to the coordinate system formed by the coordinate setting section.
