Abstract
An ophthalmologic apparatus includes an objective lens that faces a subject's eye, an illumination optical system that irradiates a cornea of the subject's eye with illumination light through the objective lens, and a corneal measurement optical system including an interference image capturing camera that takes an image of a corneal reflection light. The corneal reflection light is a reflection of the illumination light reflected from the cornea, through the objective lens. A numerical aperture G of the illumination optical system is larger than a numerical aperture g of the corneal measurement optical system.
