Science

* We spend about one-tenth of our waking hours completely blind * Only one per cent of what we see is in focus at any one time * You don't need eyes to see - blind volunteers have been taught to see through their chests Through a spellbinding mix of scientific research, mathematics, philosophy, history, myth, anecdote and language theory, Simon Ings brilliantly unravels the never-ending puzzle of how and why we see in the way that we do. With the help of a beguiling mix of illustrated visual conundrums and enigmas, Ings triumphs with a compelling dissection of the eye's age-old mysteries that is both seriously interesting and interestingly fun.
