Seeing

What actually happens inside your eyes when you read a book or watch a film?

This is an examination of how your eyes form pictures, how they focus on objects close up or far away, and how they let you see in colour.

There is information on how your eyes need looking after, how glasses work and also how blindness occurs.Part of a series on "The Body in Action", this volume contains commissioned photographs of children alongside detailed cutaway illustrations of the body in an identical pose.

The illustrations are annotated to explain anatomical features and the processes that occur inside the body.

There are "Did You Know?" panels containing further facts; "Stay Healthy" panels containing tips on how to keep the body healthy; cartoons; listings of related Web sites and suggestions for further reading; a glossary; and an index.
