An indirect ophthalmoscopy lens device includes a plurality of lenses for collecting light emanating from a patient's eye and focussing the light to form a first, real, inverted image of the fundus of the patient's eye outside of the eye, and for reinverting the first, real, inverted image to form an erect image anterior of the device. The first, real, inverted image, rather than being an aerial image, may be formed at least partially within one of the plurality of lenses of the device. A conjugate pupil image, rather than being located in air as an aerial image of the patient's pupil, may be formed within one of the plurality of lenses of the device.
