Eye Problems, Reference & Test Preparation 

This book begins with a promise: people with severe vision loss can be trained and equipped to function as sighted. The author, himself legally blind for 30 years, fulfills that promise with precise information and guidance on improving life through visual rehabilitation. The book explains fundamental facts about eyes and vision, including the causes and varieties of blindness, and then moves on to the new skills the partially sighted person must learn. Specific approaches and devices are covered in depth, including eccentric viewing and driving with telescopic glasses, and the visual and electronic aids that can help overcome the effects of vision loss. In spite of his own limited vision (20/240), Dr. Chapman uses a computer without a voice synthesizer, watches TV, and even drives, and he shows readers how to do the same. - from Amzon
