Sight is one of the main senses. Vision supports a wealth of behaviour: from picking up a cup, to writing a note, to interpreting the expression on a face, all the way to appreciating the beauty of a view. This course presents a broad overview of the interdisciplinary study of human vision starting with an introduction to its biological/physiological organisation in our species where it occupies the efforts of at least a third of the brain. We introduce students to the problems of studying visual experience. We discuss the subjective nature of perception and why studying this is fraught with both methodological and philosophical caveats. We further seek to demonstrate how visual experience differs from one person to another, both in health and disease, and we enable students to hear first-hand, the profound issues faced by individuals who experience loss of vision. Moreover, the course discusses how our understanding of human vision is supporting current breakthroughs in restoring sight after vision loss. Finally, we discuss how vision science is linked with the arts using examples of how for centuries painters have used principles of the visual system only recently discovered by science.
