From the beginning, abstraction has been intrinsic to photography, and its persistent popularity reveals much about the medium. Now available in an affordable paperback edition, The Edge of Vision: The Rise of Abstraction in Photography is the first book in English to document this phenomenon and to put it into historical context, while also examining the diverse approaches thriving within contemporary photography. Author Lyle Rexer examines abstraction at pivotal moments, starting with the inception of photography, when many of the pioneers believed the camera might reveal other aspects of reality. The Edge of Vision traces subsequent explorations--from the Photo-Secessionists, who emphasized process and emotional expression over observed reality, to Modernist and Surrealist experiments. In the decades to follow, in particular from the 1950s through the 1980s, a multitude of photographers--Edward Weston, Aaron Siskind, Barbara Kasten, Ellen Carey and James Welling among them--took up abstraction from a variety of positions. Finally, Rexer explores the influence the history of abstraction exerts on contemporary thinking about the medium. Many contemporary artists--most prominently Penelope Umbrico, Michael Flomen, and Adam Broomberg and Oliver Chanarin--reject classic definitions of photography's documentary dimension in favor of other conceptually inflected possibilities, somewhere between painting and sculpture, that include the manipulation of process and printing. In addition to Rexer's engagingly written and richly illustrated history, this volume includes a selection of primary texts from and interviews with key practitioners and critics, such as Alvin Langdon Coburn, László Moholy-Nagy, Gottfried Jägger, Silvio Wolf and Walead Beshty.

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.

The advent of photography revolutionized perception, making visible what was once impossible to see with the human eye. In At the Edge of Sight, Shawn Michelle Smith engages these dynamics of seeing and not seeing, focusing attention as much on absence as presence, on the invisible as the visible. Exploring the limits of photography and vision, she asks: What fails to register photographically, and what remains beyond the frame? What is hidden by design, and what is obscured by cultural blindness? Smith studies manifestations of photography's brush with the unseen in her own photographic work and across the wide-ranging images of early American photographers, including F. Holland Day, Eadweard Muybridge, Andrew J. Russell, Chansonetta Stanley Emmons, and Augustus Washington. She concludes by showing how concerns raised in the nineteenth century remain pertinent today in the photographs of Abu Ghraib. Ultimately, Smith explores the capacity of photography to reveal what remains beyond the edge of sight.

Pathologic Myopia is a major cause of severe vision loss worldwide. The mechanisms for vision loss include cataract, glaucoma, retinal detachment, and above all, myopic maculopathy within the posterior staphyloma. The first edition of Pathologic Myopia is one of the only current books to specifically address this disease and discusses recent developments in imaging technologies and various approaches to treatments, such as laser photocoagulation, photodynamic therapy, pharmaco-therapeutic injections in the vitreous, and surgery. This new edition is a timely update to the standard reference in the field, with new chapters on advanced refractive error correction, genetics, developing a classification system, and special surgical approaches for pathologic myopia. Complete with even more high-quality color images and informative tables, this book is written and edited by leaders in the field and is geared towards ophthalmologists, including residents and fellows in training, glaucoma and cataract specialists, and vitreoretinal macula experts.

Designing User Interfaces for an Aging Population: Towards Universal Design presents age-friendly design guidelines that are well-established, agreed-upon, research-based, actionable, and applicable across a variety of modern technology platforms. The book offers guidance for product engineers, designers, or students who want to produce technological products and online services that can be easily and successfully used by older adults and other populations. It presents typical age-related characteristics, addressing vision and visual design, hand-eye coordination and ergonomics, hearing and sound, speech and comprehension, navigation, focus, cognition, attention, learning, memory, content and writing, attitude and affect, and general accessibility. The authors explore characteristics of aging via realistic personas which demonstrate the impact of design decisions on actual users over age 55. - Presents the characteristics of older adults that can hinder use of technology - Provides guidelines for designing technology that can be used by older adults and younger people - Review real-world examples of designs that implement the guidelines and the designs that violate them
