Abstract: An ophthalmologic apparatus is provided, which is capable of more securely supporting left and right cheekbone portions of a subject in accordance with the size and shape of the subject's face allowing the subject to respond orally where the positions of the subject's eyes are fixed. The ophthalmologic apparatus includes a forehead contact portion coming into contact with the forehead of the subject, and a cheek contact portion coming into contact with the cheeks of the subject. The cheek contact portion includes a first cheek-contact body that supports one of the cheeks of the subject, a second cheek-contact body that supports the other one of the cheeks of the subject, and an opening/closing mechanism portion that opens and closes in a horizontal direction the first cheek-contact body and the second cheek-contact body in a direction of coming close to each other and a direction of separating from each other

Abstract: An ophthalmologic apparatus includes a visual target projection system that is configured to present a visual target to a subject eye at a predetermined examination distance under a presentation condition according to the examination distance, and a controller that is configured to control the visual target projection system. The controller is configured to control the visual target projection system to present the visual target at a first examination distance for a far-point examination of the subject eye, a second examination distance for a near-point examination of the subject eye, and at least one third examination distance different from the first examination distance and the second examination distance.
