ColorDx CCT-HD is designed to detect abnormalities and characterize the contrast sensitivity of the color mechanisms of the human visual system using a highly granular, cone-isolation contrast sensitivity technique.

Blue (S-scone) defects may be the most common acquired loss of chromatic discrimination.“Acquired CV defects, however, are estimated to be present in 15% of the general populationregardless of sex. Over 300 medications and disease processes are associated with inducing
CV disturbances”1. This important but often overlooked clinical sign may be caused by retinal, optic nerve, or neurological disorders, in addition to cataracts and high-risk meds, as well as hundreds of common drugs and substances2.
