Abstract: An ophthalmologic apparatus includes an objective measurement optical system that is configured to objectively measure eye characteristics of a subject eye; an optotype projection system that is configured to present a fixation target to the subject eye at a predetermined presentation position and apply fog to the subject eye; and a controller that is configured to control the objective measurement optical system and optotype projection system. The controller is further configured to objectively measure the eye characteristics over time by changing a presentation position of the fixation target from the predetermined presentation position in a direction to increase an amount of fog and presenting the fixation target.
