Purpose/indications
The slit/spot retinoscopes described in these instructions for use (aka skiascopes) were
manufactured to determine the refraction (ametropia) of the eye.
Startup and function
Attach the required instrument head to the mount on the upper part of the handle so that the
two recesses on the lower part of the instrument head align with the two protruding guide
