Abstract:
1. An eye characteristic measuring apparatus comprising: a light source part configured to emit a light flux with a first wavelength; a first illuminating optical system configured to illuminate a minute area on a retina of a subject eye with the light flux from the light source part; a first light receiving optical system configured to receive a part of a reflected light flux reflected and returned from the retina of the subject eye through a first conversion member including a lens part having a long focal point or first sensitivity and configured to convert the reflected light flux into substantially at least a second light receiving optical system configured to receive a part of the reflected light flux reflected and returned from the retina of the subject eye through a second conversion member including a lens part having a short focal point or second sensitivity and configured to convert the reflected light flux into substantially at least a first light receiving part configured to receive the received light flux of the first light receiving optical system; a second light receiving part configured to receive the received light flux of the second light receiving optical system; a measurement condition setting part configured to set a measurement condition of the first and/or the second light receiving optical system on the basis of an output signal from the second light receiving part; and an arithmetic part configured to obtain an optical characteristic of the subject eye on the basis of an output of the first light receiving part and/or the second light receiving part.
