Riester ri-scope Retinoscope
The ri-scope® retinoscope (skiascope) measures
the refractive power of the eye. Errors of refraction,
such as in short and long-sightedness, as well as
astigmatism can be recognized and determined.
Choice of XL 3.5 V xenon lamp or HL 2.5 V
Two models are available:
-The spot-light retinoscope projects a circular light
-The slit-light retinoscope with a light beam in the
form of a line, simplifies recognition and the
determination of astigmatic refractive errors. The
reflex in the form of a line is moved vertically to

oscillating movement. The shadow moves in the
same or opposite direction.
Co-movement (plus lines): The patient is longsighted.
Counter-movement (minus lines): The patient is
