The new gold standard in diagnostic color vision testing

Assess visual function beyond high-contrast acuity


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 original USAF cone-isolation contrast test (Rabin CCT) and is built from the ground up with entirely new architecture.

Highlights include: 

• Cone-isolation contrast sensitivity methodology

• Expanded low-contrast range testing

• “Landolt C” based test strategies

• Simple to use 4-button response pad

• Robust Bayesian threshold with 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

• …and much more
