Abstract

A teaching attachment for a conventional streak retinoscope allows a second observer to view the retinoscopic reflex during retinoscopy. The device weighs 200 grams and is attached to the retinoscope by a semi-flexible, rotatable linkage. A beam splitter, one-power telescope, and erecting mirror form a displaced aerial image of the retinoscope peephole for the observer. With identical retinoscopic reflexes observed through the actual peephole and its aerial image, the device can be used to teach basic retinoscopy techniques to new refractionists, or to demonstrate subtle reflexes to more experienced observers.
