Vision is the sense by which we and other animals obtain most of
our information about the world around us. Darwin appreciated that
at first sight it seems absurd that the human eye could have
evolved by natural selection. But we now know far more about
vision, the many times it has independently evolved in nature, and
the astonishing variety of ways to see. The human eye, with a lens
forming an image on a sensitive retina, represents just one.
Scallops, shrimps, and lobsters all use mirrors in different ways.
Jumping spiders scan with their front-facing eyes to check whether
the object in front is an insect to eat, another spider to mate
with, or a predator to avoid. Mantis shrimps can even measure the
polarization of light. Animal eyes are amazing structures, often
involving precision optics and impressive information processing,
mainly using wet protein - not the substance an engineer would
choose for such tasks. In Eyes to See, Michael Land, one of the
leading world experts on vision, explores the varied ways in which
sight has evolved and is used in the natural world, and describes
some of the ingenious experiments researchers have used to uncover
its secrets. He also discusses human vision, including his
experiments on how our eye movements help us to do everyday tasks,
as well as skilled ones such as sight-reading music or driving. He
ends by considering the fascinating problem of how the constantly
shifting images from our eyes are converted in the brain into the
steady and integrated conscious view of the world we experience.
