ABSTRACT:
Measurement of an eye characteristic is performed more accurately and at high speed by setting a measurement condition of a light receiving optical system with a long focal point or high sensitivity on the basis of an optical characteristic measured by a light receiving optical system with a short focal point or low sensitivity or high density. The optical characteristic of the subject eye is obtained on the basis of an output of a first light receiving part and/or a second light receiving part, and a change direction of the beam is estimated on the basis of an output signal from the second light receiving part.
