Seeing and Hearing [PDF ebook] 

Our eyes and ears are our windows on the world. For our vision and hearing to stay amazingly robust, and hold up under a lot of use, it is vitally important to make wise choices that will keep them healthy and serving us well. The fascinating text explains the anatomy of the eye and ear and how these organs work with the brain to allow us to see images and hear sounds. Chapters discuss preventable vision and hearing problems and ways young people can prevent damage to their sight and hearing, including practicing good hygiene to prevent infections, wearing protective gear during sports, and turning down the volume on mobile music players. Also discussed is how professionals evaluate sight and hearing and address deficits so people can see and hear more clearly.
