Patent ID: 7344247

Claim:
An ocular accommodative function examination apparatus for examining an accommodative function of an examinee's eye, including: a fixation target presenting optical system which presents a fixation target to the eye by changing an optical distance; a refractive power measuring optical system which measures refractive power of the eye; an analysis part which acquires variation with time of the refractive power of the eye gazing at the fixation target at a certain presenting position within a predetermined time based on a result of measurement by the measuring optical system, and performs a frequency analysis of the acquired variation to determine spectral power of high frequency component of accommodative microfluctuation of the eye; and a control part which controls presenting of the fixation target to perform at least one of simple examination in which the fixation target is presented at each of a plurality of different first presenting positions and thorough examination in which the fixation target is presented at each of a plurality of different second presenting positions, the second presenting positions including different positions more than the first presenting positions; the analysis part being adapted to determine the spectral power of high frequency component of accommodative microfluctuation of the eye at each of the presenting positions.
