    • A method and apparatus is disclosed for examining and/or classifying properties of a subject's colour vision. The apparatus consists of a Cathode Ray Tube (CRT) (10) displaying a first colour (20) and a second colour (30), each composed of the same colour components. The subject is required to modify one of the colours within available constraints to match the two colours and parameters are derived from the subject's performance. These parameters are then compared with corresponding parameters which are correlated to a colour vision property. One of the parameters that can be compared relates to an angle of an isochromatic line resulting from the subject's test.

A plurality of narrow-band light sources are combined to constitute a colour controllable lamp. A method for adjusting the settings of this lamp permits the optimum illumination for a particular subject to be found, whilst the latter carries out a task such as reading or writing. By use of the lamp to simulate the expected visual stimulus, to which the subject would be exposed if provided with viewing aids such as tinted spectacles and the like, an optimal selection from a database of such aids may be made or a new formulation defined. Inter alia, the symptoms of visual dyslexia, macular generation and visually induced migraine may be alleviated.
