Mollon-Reffin Colour Vision Test
The Mollon-Reffin Colour Vision Test assesses a patient's ability to detect colour across three theoretically significant axes of colour space. It is a quick and simple test to complete - making it ideal for assessing colour deficiency in children - yet it provides valuable and accurate information on the type and degree of colour deficiency, if present.

About the Mollon-Reffin Colour Vision Test
The Mollon-Reffin Colour Vision Test identifies and classifies the dichromatic type of inherited colour blindness, as well as anomalous trichromats with impaired colour discrimination. It is easy to understand, and makes minimal demands of the patient's concentration. As a result, it is suitable for testing not only healthy adults, but also children, the elderly and patients with neurological problems. In fact, this method is ideal for testing young children, and the test has been completed by children as young as three years old.
How the Test Works
The Mollon-Reffin Colour Vision testing kit consists of a set of grey caps of varying lightness, three sets of coloured caps, one demonstration pointer, and a manual. The test is packaged in a perspex box, the lid of which is used to set out the test.
To perform the test, the grey caps are arranged on the lid of the box - along with only one of the coloured caps - and the test subject is then asked to identify the coloured cap. Throughout the test different coloured caps are placed among the grey caps, and the patient is asked to identify the coloured cap each time. Based on the accuracy of the patient in identifying the coloured caps, the examiner will be able to diagnose colour blindness or any deficiency in discriminating between colours.
