Abstract
An adaptive optics apparatus includes an aberration measuring unit that measures an aberration caused by a subject's eye, the aberration being measured on the basis of returning light that returns from the subject's eye; an aberration correcting unit that performs aberration correction in accordance with the aberration measured by the aberration measuring unit; an irradiation unit that irradiates the subject's eye with light corrected by the aberration correcting unit; and an adjusting unit that maintains a correction characteristic of the aberration correcting unit when the subject's eye moves out of a predetermined area.
