From the famed poet Homer to King John of Bohemia, people without sight have always been prominent in our collective history. These figures have been heroised, demonised, and everything in between. The retelling of their lives indicates that blindness is typically seen as either an affliction to be 'fixed', or as a superpower; it has been given a mystical quality whereby a person can lose their vision, but gain wisdom.
Dan is joined by Selina Mills, broadcaster and author of Life Unseen: A Story of Blindness, who explains how societies have responded throughout the ages to people who are blind.
