• "I got Waggoner CCVT downloaded and the first patient I saw today was a 3 year old whose mother complained that she is having a hard time teaching the child colors and she feels like she is color blind. She turned out to have a protan defect! It was great because usually I would have to send someone to another office for extended color vision. Glad I learned about this awesome program!"

  • "Based on preliminary findings the Waggoner CCVT has increased sensitivity and specificity compared to the Ishihara PIP and FALANT, and is comparable to the Nagel Anomaloscope. The design of the Waggoner CCVT reduces administration errors. Current color vision screening tests fail to identify all color deficient applicants. The CCVT appears to be a reliable, sensitive, and specific test for screening color vision in aviation applicants."
