Eyes to eyes. How animals see the world

The vision of the animals is not the same as in humans. Some of them distinguish only light and shadow, others are able to notice only mobile objects, but there are those who see what is inaccessible to the human eye. Steve Jenkins talks about a diverse structure and functions of visual organs on the example of specific animals. Look at the world with their eyes!
Since childhood, we hear that the eye is a perfect optical device created by nature itself. But how did nature manage to create it? Did such a complex organ appear immediately, and if not, what were the stages of its development? And do all animals on earth boast of such excellent vision as, say, ordinary kanyuk or cancer-Bogomol (yes, in terms of vision is not a champion at all)?
The book "Eye in the Eye" book will answer these and other questions, from which you will learn many curious information about the main stages of vision evolution (it turns out that for three billion years the animals have even remained blind!), The eye structure of various representatives of the animal The world, from the sea star (however, these poor people do not even have eyes, but a simple accumulation of photosensitive cells) to a home cat. Well, and remembers all this will help you beautiful illustrations!
