An adaptive optics apparatus includes aberration measuring means (115) that measures an aberration caused by a subjects eye (111), the aberration being measured on the basis of returning light that returns from the subjects eye (111) aberration correcting means (108) that performs aberration correction in accordance with the aberration measured by the aberration measuring means (115) irradiation means that irradiates the subjects eye (111) with light corrected by the aberration correcting means (108) and adjusting means that maintains a correction characteristic of the aberration correcting means (108) when the subjects eye (111) moves out of a predetermined area.
