Book Description
The ability to see deeply affects how human beings perceive and interpret the world around them. For most people, eyesight is part of everyday communication, social activities, educational and professional pursuits, the care of others, and the maintenance of personal health, independence, and mobility. Functioning eyes and vision system can reduce an adult's risk of chronic health conditions, death, falls and injuries, social isolation, depression, and other psychological problems. In children, properly maintained eye and vision health contributes to a child's social development, academic achievement, and better health across the lifespan. The public generally recognizes its reliance on sight and fears its loss, but emphasis on eye and vision health, in general, has not been integrated into daily life to the same extent as other health promotion activities, such as teeth brushing; hand washing; physical and mental exercise; and various injury prevention behaviors. A larger population health approach is needed to engage a wide range of stakeholders in coordinated efforts that can sustain the scope of behavior change. The shaping of socioeconomic environments can eventually lead to new social norms that promote eye and vision health. Making Eye Health a Population Health Imperative: Vision for Tomorrow proposes a new population-centered framework to guide action and coordination among various, and sometimes competing, stakeholders in pursuit of improved eye and vision health and health equity in the United States. Building on the momentum of previous public health efforts, this report also introduces a model for action that highlights different levels of prevention activities across a range of stakeholders and provides specific examples of how population health strategies can be translated into cohesive areas for action at federal, state, and local levels.

Book Description
NATIONAL BESTSELLER • From “the poet laureate of medicine" (The New York Times) and the author of the classic The Man Who Mistook his Wife for a Hat comes a fascinating exploration of the remarkable, unpredictable ways that our brains cope with the loss of sight by finding rich new forms of perception. “Elaborate and gorgeously detailed.... Again and again, Sacks invites readers to imagine their way into minds unlike their own, encouraging a radical form of empathy.” —Los Angeles Times With compassion and insight, Dr. Oliver Sacks again illuminates the mysteries of the brain by introducing us to some remarkable characters, including Pat, who remains a vivacious communicator despite the stroke that deprives her of speech, and Howard, a novelist who loses the ability to read. Sacks investigates those who can see perfectly well but are unable to recognize faces, even those of their own children. He describes totally blind people who navigate by touch and smell; and others who, ironically, become hyper-visual. Finally, he recounts his own battle with an eye tumor and the strange visual symptoms it caused. As he has done in classics like The Man Who Mistook his Wife for a Hat and Awakenings, Dr. Sacks shows us that medicine is both an art and a science, and that our ability to imagine what it is to see with another person's mind is what makes us truly human.

Book Description
In The Vision Revolution: How the Latest Research Overturns Everything We Thought We Knew About Human Vision, Mark Changizi, prominent neuroscientist and vision expert, addresses four areas of human vision and provides explanations for why we have those particular abilities, complete with a number of full-color illustrations to demonstrate his conclusions and to engage the reader. Written for both the casual reader and the science buff hungry for new information, The Vision Revolution is a resource that dispels commonly believed perceptions about sight and offers answers drawn from the field's most recent research. Changizi focuses on four “why" questions: 1. Why do we see in color? 2. Why do our eyes face forward? 3. Why do we see illusions? 4. Why does reading come so naturally to us? Why Do We See in Color? It was commonly believed that color vision evolved to help our primitive ancestors identify ripe fruit. Changizi says we should look closer to home: ourselves. Human color vision evolved to give us greater insights into the mental states and health of other people. People who can see color changes in skin have an advantage over their color-blind counterparts; they can see when people are blushing with embarrassment, purple-faced with exertion or the reddening of rashes. Changizi's research reveals that the cones in our eyes that allow us to see color are exquisitely designed exactly for seeing color changes in the skin. And it's no coincidence that the primates with color vision are the ones with bare spots on their faces and other body parts; Changizi shows that the development of color vision in higher primates closely parallels the loss of facial hair, culminating in the near hairlessness and highly developed color vision of humans. Why Do Our Eyes Face Forward? Forward-facing eyes set us apart from most mammals, and there is much dispute as to why we have them. While some speculate that we evolved this feature to give us depth perception available through stereo vision, this type of vision only allows us to see short distances, and we already have other mechanisms that help us to estimate distance. Changizi's research shows that with two forward-facing eyes, primates and humans have an x-ray ability. Specifically, we're able to see through the cluttered leaves of the forest environment in which we evolved. This feature helps primates see their targets in a crowded, encroached environment. To see how this works, hold a finger in front of your eyes. You'll find that you're able to look “through" it, at what is beyond your finger. One of the most amazing feats of two forward-facing eyes? Our views aren't blocked by our noses, beaks, etc. Why Do We See Illusions? We evolved to see moving objects, not where they are, but where they are going to be. Without this ability, we couldn't catch a ball because the brain's ability to process visual information isn't fast enough to allow us to put our hands in the right place to intersect for a rapidly approaching baseball. “If our brains simply created a perception of the way the world was at the time light hit the eye, then by the time that perception was elicited—which takes about a tenth of a second for the brain to do—time would have marched on, and the perception would be of the recent past," Changizi explains. Simply put, illusions occur when our brain is tricked into thinking that a stationary two-dimensional picture has an element that is moving. Our brains project the “moving" element into the future and, as a result, we don't see what's on the page, but what our brain thinks will be the case a fraction of a second into the future. Why Does Reading Come So Naturally to Us? We can read faster than we can hear, which is odd, considering that reading is relatively recent,

Book Description
In this New York Times bestseller, Isaac Lidsky draws on his experience of achieving immense success, joy, and fulfillment while losing his sight to a blinding disease to show us that it isn’t external circumstances, but how we perceive and respond to them, that governs our reality. Fear has a tendency to give us tunnel vision—we fill the unknown with our worst imaginings and cling to what’s familiar. But when confronted with new challenges, we need to think more broadly and adapt. When Isaac Lidsky learned that he was beginning to go blind at age thirteen, eventually losing his sight entirely by the time he was twenty-five, he initially thought that blindness would mean an end to his early success and his hopes for the future. Paradoxically, losing his sight gave him the vision to take responsibility for his reality and thrive. Lidsky graduated from Harvard College at age nineteen, served as a Supreme Court law clerk, fathered four children, and turned a failing construction subcontractor into a highly profitable business. Whether we’re blind or not, our vision is limited by our past experiences, biases, and emotions. Lidsky shows us how we can overcome paralyzing fears, avoid falling prey to our own assumptions and faulty leaps of logic, silence our inner critic, harness our strength, and live with open hearts and minds. In sharing his hard-won insights, Lidsky shows us how we too can confront life's trials with initiative, humor, and grace.

Book Description
Vision is the sense by which we and other animals obtain most of our information about the world around us. Darwin appreciated that at first sight it seems absurd that the human eye could have evolved by natural selection. But we now know far more about vision, the many times it has independently evolved in nature, and the astonishing variety of ways to see. The human eye, with a lens forming an image on a sensitive retina, represents just one. Scallops, shrimps, and lobsters all use mirrors in different ways. Jumping spiders scan with their front-facing eyes to check whether the object in front is an insect to eat, another spider to mate with, or a predator to avoid. Mantis shrimps can even measure the polarization of light. Animal eyes are amazing structures, often involving precision optics and impressive information processing, mainly using wet protein - not the substance an engineer would choose for such tasks. In Eyes to See, Michael Land, one of the leading world experts on vision, explores the varied ways in which sight has evolved and is used in the natural world, and describes some of the ingenious experiments researchers have used to uncover its secrets. He also discusses human vision, including his experiments on how our eye movements help us to do everyday tasks, as well as skilled ones such as sight-reading music or driving. He ends by considering the fascinating problem of how the constantly shifting images from our eyes are converted in the brain into the steady and integrated conscious view of the world we experience.

Book Description
This book was first projected in 2004, when Author Hannah Fairbairn was teaching interpersonal skills at the Carroll Center for the Blind in Newton, Massachusetts. The experiences of her adult students—and her own experience of sight lost—convinced her that everyone losing vision needs access to good information about the process of adjustment to losing sight and practical ways to use assertive speech. When You Can’t Believe Your Eyes is intended for anyone going through vision loss, their friends, and families. It will inform readers how to get expert professional help, face the trauma of loss, and navigate the world using speech more than sight. Each of the twelve chapters in the book contain many short sections and bullet-point lists, intended to facilitate access to the right information. It begins where you begin—at the doctor’s office or the hospital. Since vision loss takes many forms, there are suggestions for questions you might ask to get a clear diagnosis and the best treatment. Part One also has a description of legal blindness and possible prevention, advice about your job, and tips for life at home. Part Two is about believing in yourself as you deal with the loss, the anger, and the fear before you come up for air and consider training. Parts Three and Four describe using assertive speech and action in all kinds of settings as your independence and confidence increase. Part Five gives detailed information about everything from dating, and caring for babies to senior living, volunteering, and retaining your job. It is hoped that by reading and trying out the suggestions, the reader will recover full confidence, become a positive, assertive communicator, and lead a satisfying life. Because vision loss happens mostly in older years, the book is written with seniors particularly in mind. Professionals will also find it to be a useful resource for their patients.
