Patent ID: 7249851

Claim:
An eye characteristic measuring apparatus comprising: a light source unit for emitting a light flux with a first wavelength; a first illumination optical system for illuminating a small area on a retina of a subject eye with the light flux from the light source unit; a first light reception optical system for leading a part of a first reflected light flux reflected by and returning from the retina of the subject eye to be received through a first conversion member for converting it into at least substantially 17 beams; a first light reception unit for receiving the received light flux of the first light reception optical system to form a first signal; a measurement data judgment unit for judging, on the basis of the first signal from the first light reception unit, whether measurement data is appropriate for obtaining a wavefront aberration; a first correction unit for causing a check correction screen to be displayed when the measurement data judgment unit judges that the measurement data is inappropriate and for correcting it into appropriate measurement data; a calculation unit for calculating the wavefront aberration of the subject eye as optical characteristic on the basis of the measurement data which has been judged to be appropriate by the measurement data judgment unit or the measurement data which has been corrected by the first correction unit; and a display unit for displaying the wavefront aberration as a calculation result of the calculation unit.
