The Eyes Have It

January 1, 2018
Grades 5-8 Learning that the brain has 100 to 200 billion neurons or that each cell makes 30,000 to 70,000 repairs a day reveals that the title of this series, the Amazing Human Body, is accurate indeed. Complemented with large, colorful photographs and diagrams, each title begins with an overview of the organ or body process and continues with more information about functions and anomalies. The Eyes Have It explains the difference between sight and vision, the eye-brain connection needed for sight, and how color vision works (or doesn't work in the case of color blindness ). A concluding chapter looks at possibilities of the future, including artificial blood and bionic vision.
