- 摘要：
PROBLEM TO BE SOLVED: To provide an apparatus for measuring chromatic aberration of the eyes, that is, change in wavefront aberration for each wavelength.
SOLUTION: The apparatus for measuring wavefront aberration 1 includes a light source section 11 that emits light with a plurality of wavelengths in a switchable manner, an illuminating optical system 10 that changes illuminating light flux emitted from the light source section 11 into spotlight and illuminates the fundus 81 of a subject eye 80 with the spotlight, a Hartmann plate 22 that divides reflected light flux from the fundus 81 into a plurality of divided light fluxes, a light receiving optical system 20 having a light receiving section 21 for receiving the plurality of divided light fluxes divided by the Hartmann plate 22, a wavefront aberration calculating section 901 that acquires wavefront aberration for light of each wavelength received at the light receiving section 21, and a chromatic aberration calculating section 902 that acquires chromatic aberration of the wavefront on the basis of the wavefront aberration of each wavelength acquired by the wavefront aberration calculating section 901.
