Abstract
An ophthalmic apparatus includes an objective lens, a first illumination optical system arranged approximately coaxially with an optical axis of the objective lens and configured to be capable of irradiating first illumination light onto an eye to be examined through the objective lens, a second illumination optical system arranged so as to be eccentric to the optical axis of the objective lens and configured to be capable of irradiating second illumination light onto the eye to be examined through the objective lens, a left-eye observation optical system configured to be capable of guiding returning light from the eye to be examined, where the first illumination light or the second illumination light has entered through the objective lens, to a left-eye eyepiece or a left-eye imaging element, and a right-eye observation optical system configured to be capable of guiding returning light from the eye to be examined, where the first illumination light or the second illumination light has entered through the objective lens, to a right-eye eyepiece or a right-eye imaging element. The second illumination optical system is capable of changing an incident angle of a principal ray of the second illumination light relative to the eye to be examined.
