Screen with dynamic polarization

Features and Benefits

  • Linear polarization
  • Sharpness, width, connections on the rear
  • Comprehensive range of applications from low vision (ETDRS) to hyper acuity
  • Screening for color vision deficiency
  • Contrast Test (useful after cataract or refractive surgery)
  • Working distance adjustable from 2 to 8 meters (6.5- 26 feet)
  • Upgradable when new tests are added
  • Multimedia feature (videos)
  • New frame to better bring out the tests from the environement
Advanced analysis of the binocular function
  • The use of the 3D polarization screen is one of the key features of this device allowing a perfect dissociation of the right eye/left eye. This offers the ability to proceed with many other tests with optimal quality for the exam of bi-ocular, binocular, and stereoscopic vision.
A very intuitive menu
  • With an accessible duochrome calibration (for a perfect and customized extinction of your red-green filter, whatever phoropter or trial frame you use).
  • Series of optotypes: letters, numbers, Snellen tridents, Landolt rings, 4 ranges for kids
  • Large range of acuities on all tests: from 0.05 to 2.00 with many steps
  • Decimal or logarithmic progression (available scores: Monoyer, decimal, LogMAR, and Snellen)
  • Abililty to change the displayed letters by pushing on CHANG
  • Isolated optotype, line, or triple display on the same or different acuity
  • R/G test available on any test at any time
