The structure and function of all kinds of eyes are given a precise and readable treatment enhanced by color photos. Packed with fascinating facts, the text is at times technical but is logically organized and clear; specialized terms are well-defined. Among other kinds of eyes discussed: starfish eyes, found on their feet; the pale blue, single-lens eyes that rim the scallop's shell; the compound, polarized eyes of a horsefly; the mirror eyes of the lobster. Format is unusually appealing: glossy paper, jewel-like close-ups, accessible layout, helpful guide words. An excellent resource. Index. (Nonfiction. 10+)
