Written by a leader in the field, this book discusses the role of vision in reading. The author describes the influence of physical properties of text on reading performance and the implications for information processing in the visual pathways. He explores different forms of low vision that affect reading, text characteristics that optimize reading for those with low vision, principles underlying the legibility of text, and guidelines for displaying text. Special topics include the role of the magnocellular pathway in reading and dyslexia, Braille reading, and fonts for highway signs. An accompanying CD contains reprints of the seminal series of articles by Gordon E. Legge and colleagues published between 1985 and 2001.
