Abstract:
An eye characteristic measuring apparatus comprising:a first light source that emits light of a first wavelength; a first illuminating optical system capable of illuminating a small region of the retina of an eye in a variable illuminating condition with the light emitted by the first light source; a first photodetecting optical system provided with a first transforming device that divides reflected light reflected from the retina of the eye into a least seventeen light beams and a first photodetecting device that receives part of the reflected light reflected from the retina through the first transforming device; an arithmetic unit that determines optical characteristics of the eye on the basis of a first signal provided by the first photodetecting device and corresponding to inclination of the transforming light from transform device; and an image forming condition changing unit that changes respective image forming conditions of the first illuminating optical system and the first photodecting optical system according to the first signal provided by the first photodetecting device to set a first changed state and changes respective image forming conditions of the first illuminating optical system and the first photodetecting optical system according to optical characteristics determined by the arithmetic unit to set a second changed state.
