Retinoscope Features

• External focusing sleeve allows for easy
adjustment no matter what size hand or
how instrument is held. Continuous 360˚
rotation.
• Dust free optics to keep instrument
clean longer.
• Fixation cards that easily attach for use
during dynamic retinoscopy.
• Collapsable head for compact size (protection against damaging optics).

Retinoscope Operation

The operator will note that the width of the streak varies as the sleeve is
raised and lowered. When the operating sleeve is in the lowest posi-
tion, the light rays emitted are slightly divergent.
reflects divergent rays that will never come to a focus. As the
sleeve is raised, the streak focuses. With the sleeve all the way
mechanism allows the streak to rotate 360˚ to ascertain the axis of astigmatism.
