Book Description
Advances in technology allow us to see the invisible: fetal heartbeats, seismic activity, cell mutations, virtual space. Yet in an age when experience is so intensely mediated by visual records, the centuries-old realization that knowledge gained through sight is inherently fallible takes on troubling new dimensions. This book considers the ways in which seeing, over time, has become the foundation for knowing (or at least for what we think we know). A. Joan Saab examines the scientific and socially constructed aspects of seeing in order to delineate a genealogy of visuality from the Renaissance to the present, demonstrating that what we see and how we see it are often historically situated and culturally constructed. Through a series of linked case studies that highlight moments of seeming disconnect between seeing and believing—hoaxes, miracles, spirit paintings, manipulated photographs, and holograms, to name just a few—she interrogates the relationship between “visions” and visuality. This focus on the strange and the wonderful in understanding changing notions of visions and visual culture is a compelling entry point into the increasingly urgent topic of technologically enhanced representations of reality. Accessibly written and thoroughly enlightening, Objects of Vision is a concise history of the connections between seeing and knowing that will appeal to students and teachers of visual studies and sensory, social, and cultural history.

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
Have you ever wondered how the images in your eyes become your perception of the world about you? Michael W. Levine, professor emeritus at the University of Illinois at Chicago, examines the how and what of vision in this book. From the images in your eyes, through the processing by your brain, to the creation of perceptions of the world, he explores why and how we see the world as we do. The author considers the phenomena of optical illusions, mistaken perceptions or interpretations, and impossible and ambiguous pictures, sharing his personal take on how the visual system works and what it does to enable us to recognize objects, scenes, and visual space. The most important aspect of vision that emerges in these pages is that when we see, our brains essentially create a visual world from the relatively sparse information that is presented by our eyes. Get a revealing glimpse into the workings of our visual systems and discover the beauty and wonder of the miracle of sight with Believing Is Seeing.

Book Description
Recent vision research has led to the emergence of new techniques that offer exciting potential for a more complete assessment of vision in clinical, industrial, and military settings. Emergent Techniques for Assessment of Visual Performance examines four areas of vision testing that offer potential for improved assessment of visual capability including: contrast sensitivity function, dark-focus of accommodation, dynamic visual acuity and dynamic depth tracking, and ambient and focal vision. In contrast to studies of accepted practices, this report focuses on emerging techniques that could help determine whether people have the vision necessary to do their jobs. In addition to examining some of these emerging techniques, the report identifies their usefulness in predicting performance on other visual and visual-motor tasks, and makes recommendations for future research. Emergent Techniques for Assessment of Visual Performance provides summary recommendations for research that will have significant value and policy implications for the next 5 to 10 years. The content and conclusions of this report can serve as a useful resource for those responsible for screening industrial and military visual function.
