RIESTER STREAK RETINOSCOPE

  • The spot-light retinoscope projects a circular light beam.
  • 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 the axis across the pupils of the patient with a slight oscillating movement. The shadow moves in the same or opposite direction.
    Co-movement (plus lines): The patient is long-sighted.
    Counter-movement (minus lines): The patient is short-sighted.
  • Simple operation with knurled thumb screw. The line and spot image can be focussed with the operating element and turned 360º, angle can be read off the integrated scale.
  • Holder for hanging and fixing the fixation card into position for dynamic retinoscopy.
  • Two fixation cards supplied. The patient’s eye can adjust optimally to the distance to the retinoscope.
