Clinical Benefits of Diagnostic Color Vision Testing

Tritan deficiencies are rarely genetic, yet as high as 15% of the general population may have an acquired deficiency. This is an important but often overlooked sign that may be caused by retinal, optic nerve, or neurological disorders, in addition to trauma, cataracts, and hundreds of common drugs and substances.

Testing for acquired color vision deficiencies is underutilized. Traditional tests like the D15 have low sensitivity, while the more sensitive D100 simply takes too long to be practical. Other computerized color vision tests are expensive, costing thousands more than ColorDx.

ColorDx Applications

Pediatric Color Vision Testing

Pediatric Color Vision Testing

Approximately 8% of males and 0.5% of females are born with color vision deficiencies, therefore children, especially males, should have their color vision tested before they start school, ideally in pre-school. Awareness of color vision deficiencies in children is critical for learning and socializing.

The Pediatric test (Dr. Waggoner’s “CVTME” Color Vision Testing Made Easy) is the gold standard for child / illiterate friendly color vision tests and is now available electronically on all ColorDx platforms.

Vocational and Acquired Color Vision Deficiency Testing

Many occupations and professions require normal color vision to either perform the job or to maintain public safety. Examples include military and civilian pilots (and navigators), air traffic controllers, nurses, lab technicians, school bus drivers, some law enforcement personnel, electricians, electronic technicians, and railroad conductors.

ColorDx is a comprehensive test validated by the Naval Aerospace Medical Institute for the assessment of color vision deficiencies by type (Protan, Deutan, Tritan) and severity (mild, moderate, severe), and generates a self-scored report.
