If we have our sleeve down with our retinoscope, how is the mirror positioned?

Explanation:
With the sleeve down, the retinoscope is set to use the plane mirror. The sleeve switch changes which mirror is in the optical path: down puts in the flat, plane mirror, which provides a direct, non-magnified reflex that you observe to judge refractive error and neutralize. If you raised the sleeve, the instrument would switch to a concave mirror, which is a different mode with magnification and different reflex cues. So the sleeve-down position corresponds to a plane mirror.
