There is provided an ophthalmologic apparatus that prevents ghost light from generating. In the ophthalmologic apparatus, on an optical path commonly used for an eye fundus illumination optical system and an image taking optical system including an image taking diaphragm, an objective lens for forming an image of the image taking diaphragm onto an anterior ocular segment of an eye to be examined is provided. The objective lens is formed such that the entire light beam from the center of the image taking diaphragm is substantially perpendicularly incident thereon. The objective lens is a refractive index distributed lens in which a refractive index is high in a vicinity of an optical axis and reduces as a distance from the optical axis increases.
