Improvement of the colour discrimination ability of colour deficient people by modifying the parameters of the illumination

At the Department of Mechatronics, Optics and Engineering Informatics of BME the researches led by Dr. György Ábraham and Dr. Klára Wenzel have shown that defective color vision can be improved by specific spectral transmission color filters which modify the spectral characteristics of the lights reflected by different coloured surfaces so that the difference between colors will be increased. These color filters placed in front of the eye can be used as glasses. Similar effect can be achieved in artificial lighting conditions if we modify the spectral distribution not the light reflected from the surfaces but the light emitted by light sources. This solution can be used for example as a workspace illumination when carrying out tasks that require good color vision, or as a whole room illumination, which ensures more colorful environment for colour deficient people as well.
