Abstract
An image source of an optical ophthalmic apparatus provides a picture and directs light of the picture toward an imaging arrangement of the optical ophthalmic apparatus. The imaging arrangement receives light of the picture and forms, together with refraction of an eye, an image of the picture on a first image plane, and the imaging arrangement locates the first image plane at a known location. The imaging arrangement receives light from a retina of the eye and directs light from the retina to an image detector of the optical ophthalmic apparatus, and the imaging arrangement forms, together with refraction of the eye, an image of the retina on a second image plane. The imaging arrangement forms optical conjugates of the first and second image planes for focusing the image of the retina accurately on an image sensor of the image detector if the image of the picture is simultaneously accurately focused on the retina of the eye, and the optical ophthalmic apparatus stimulates the eye to accommodate in order to focus the image of the picture accurately on the retina if the image of the picture is out-of-focus on the retina.
