Abstract
A streak retinoscope projects an elongate patch of light onto the retina of an eye under examination. A housing ( ) contains means for rotating the patch relative to the eye and adjustable focusing means for focusing the patch on the eye. Both the rotation means and the focusing means are adjusted by a single control member, such as sleeve ( ), which encircles at least part of the housing member. The control member is coupled at least to the rotation means (and preferably also to the focusing means) by a magnetic linkage so as to permit rotation of the control member on the housing through at least one full revolution.
