Approved by the Surgeon General as the Gold Standard for color vision testing for the US Air Force, Innova’s CCT uses cone sensitivity threshold testing to accurately detect shifts that may indicate the onset of eye disease.


With the Rabin Cone Contrast Test (CCT), early detection may prevent permanent damage normally associated with macular degeneration (AMD), glaucoma and diabetic retinopathy. Unlike other color vision tests, the Rabin Cone Contrast Test measures the severity of cone function loss, and tracks cone function over time, aiding in detection of disease as well as monitoring disease progression and efficacy of treatment.
