We are offering to test and diagnose colour vision deficiencies, in particular all X-linked colour deficiencies commonly referred to as red-green colour blindness. Depending on the tests used, a session can be between one to two hours long and be performed in either a single or two separate sittings.
Typically, a secure diagnosis can be achieved in 20 minutes. All tests are non-invasive and simply involve the client to making judgments (eg discriminating, matching, ordering, naming) of coloured lights or pigment samples under standardised lighting conditions.
We use a comprehensive battery of both clinical tests and more sophisticated tests initially developed for research purposes. Clinical tests include the Ishihara Plates, the Neitz Test, the Farnsworth-Munsell 100-Hue test, the Cambridge Colour Test, and the Anomaloscope.
These tests are norm-referenced behavioural tests in which procedures follow strict, pre-specified rules. In addition, we are offering to test our clients with equipment uniquely developed at Newcastle University. These include a Maxwellian-view colorimeter and a specifically designed viewing booth.
