If you've ever been curious about how your eyes work, why some people need glasses, or what the difference is between being near-sighted and far-sighted, How Do You See the World? has the answers! Eyes are complicated, and each little part has to work together in order to build a clear picture of what you see. Engaging science content covers eye anatomy, how light enters our eyes and sends an image to our brain, how we see color, and even ways we can perceive invisible light. Written by an optical physicist, this informative picture book explores the various eye conditions that kids may have or may learn about through their friends and relatives. Discover clear explanations of eye conditions such as amblyopia, astigmatism, color-blindness, and glaucoma, paired with illustrations that show how these conditions affect what you see, and what tools you can use to improve your vision.
