Abstract

Provided is an ophthalmologic apparatus capable of determining whether measurement light is properly projected onto an eye to be examined. The apparatus includes an ocular characteristics measurement unit that measures an optical characteristic of the eye by projecting measurement light onto the eye and receiving light reflected by the eye, an observation optical system that acquires an image of an anterior ocular segment, a measurement area projection optical system that projects measurement area index light onto a cornea of the eye from a position defined in accordance with an optical axis of the ocular measurement unit, and a control unit that controls the ocular characteristics measurement unit, the observation optical system, and the measurement area projection optical system. The control unit determines whether the measurement light is properly projected onto the eye based on the acquired image of the anterior ocular segment including the measurement area index light.
