An eyeball optical measurement apparatus includes a light radiating unit that radiates light toward an anterior chamber of an eyeball of a measurement subject a light receiving unit that receives the light that has passed through the anterior chamber an eyeball observation unit that observes an optical path relative to the eyeball while the light is radiated from the light radiating unit and a controller that controls the light radiating unit so as to change a position at which the eyeball is irradiated with the light on the basis of a result of the observation of the eyeball by the eyeball observation unit.
