Aspheric condensing lens 20 D
The 20 D lens is the standard lens for binocular indirect ophthalmoscopy: it gives a wide view of the retina, so you get a quick overview and can assess the periphery.
The aspheric surface limits image errors towards the edge of the field, so the image stays clear. With a working distance of 47 mm you keep room between the lens and the eye, which is pleasant during a longer examination.
