ColorDx CCT HD represents the new gold standard for color vision diagnostics. Developed in collaboration with the U.S. Air Force School of Aerospace Medicine OBVA (Operational Based Vision Assessment) laboratory under CRADA, CCT HD expands on the strengths of the USAF cone-isolation contrast test (CCT) and is built from the ground up with entirely new architecture.

  • Cone-Isolation, contrast sensitivity methodology
  • Expanded low-contrast range testing
  • “Landolt C” based test strategies
  • Simple to use 4-button response pad
  • Robust thresholding and derivation of statistic standard error
  • Konan custom-calibrated IPS matte display technology
  • Rapid, intuitive, staged calibration
  • High fidelity cone-contrast granularity
  • Expansive illustrated reporting
  • Auto trends analysis
  • Contrast Sensitivity (achromatic) with auto AUC calculation
