ZEISS Subjective Refraction Unit saves time in the refraction process and reduces the risk of significant deviations.

ZEISS Subjective Refraction Unit saves time in the refraction process and reduces the risk of significant deviations.

Take advantage of the new  built-in refraction logic and of the supportive control elements and functions, e.g. fogging buttons, and the automatically inserted age-related addition to speed up your examination.

  • On average, ZEISS Subjective Refraction Unit offers 18 % faster refraction time compared to a manual phoropter, and 24 % faster refraction time compared to a trial frame refraction.1
  • ZEISS Subjective Refraction Unit reduces the risk of significant deviation within subjective refraction by 50 % compared to a manual phoropter, and by 70 % compared to a trial frame.1
Secure patients’ trust by performing refraction with advanced vision-testing technology.

  • Combine ZEISS refraction instruments to provide an examination room experience that delivers highly precise results your patient can trust.
  • The fully integrated Graphical User Interface allows both the phoropter and visual acuity screen to be controlled simultaneously and wirelessly. This allows the user to single-handedly operate while ensuring a safe social distance.
  • Get accurate results with minimum subjective dependency on your patients.
  • Customise several refraction workflows and compare different prescriptions with just one click.
  • Connecting objective and subjective refraction devices to the practice is possible with ZEISS VISUCONSULT 500. It is easy and convenient and enables a completely paperless workflow, eliminating error-prone manual data entry and inevitably increasing staff efficiency.
  • Patient data can be stored centrally, making it remotely accessible to any authorised member of staff, at any time.
Focus on the unique needs of every patient.

  • Smart and preconfigured refraction workflows let you get right down to work.
  • Choose one of up to six default workflows or customise your own personalised workflow.
  • Streamlined workflow in the examination room creates a professional impression for your patient.
  • With more than 130 test charts (ZEISS VISUSCREEN 500) , the examination you need is always at hand – you can easily create a "binocular" or "near vision" refraction workflow along with many more.
  • Additional features include an integrated LED for the Maddox Rod test  and ZEISS i.Scription Technology demonstration.
  • Fast and smooth exchange of trial lenses allows real-time demonstration of final prescription and vision improvement.

  • Fits into small examination rooms with  a distance of 2  m in indirect use, supported by an automated size adjustment of the optotypes for the distance used.

  • Flat-screen design with a premium glass front panel prevents steps or shadows.

  • Crystal clear LCD screen with  polarised  technology (ZEISS VISUSCREEN 500) or red/green separation (ZEISS VISUSCREEN 100).

  • Integrated LED as an additional test feature for the Maddox Rod test and ZEISS  i.Scription  technology demonstration.

  • Fast and smooth exchange of trial lenses allows real-time demonstration of final prescription and vision improvement.

  • The Subjective Refraction Unit can be linked to ZEISS VISULENS  550, ZEISS VISUREF  150  and ZEISS  i.Profiler plus for direct data transfer via ZEISS VISUCONSULT 500.
