currently there are no introductory books on the market that take such an interdisciplinary approach to the subject, integrating perspectives from philosophy, biophysics, neurophysiology, genetics, medicine and psychology. colour science and engineering is a fast developing field and one that currently does not have a textbook that integrates physics, perception and visual biology into one volume. originally published in norwegian by tapir (1998) this english edition will be extensively revised and updated to include new chapters on clinical problems and eye diseases, low vision rehabilitation and the basic molecular biology and genetics of colour vision.
