An investigation of the effects of blindness and other types of visual deficit on cognitive abilities. Can a blind person see? The very idea seems paradoxical. And yet, if we conceive of "seeing" as the ability to generate internal mental representations that may contain visual details, the idea of blind vision becomes a concept subject to investigation. In this book, Zaira Cattaneo and Tomaso Vecchi examine the effects of blindness and other types of visual deficit on the development and functioning of the human cognitive system. Drawing on behavioral and neurophysiological data, Cattaneo and Vecchi analyze research on mental imagery, spatial cognition, and compensatory mechanisms at the sensorial, cognitive, and cortical levels in individuals with complete or profound visual impairment. They find that our brain does not need our eyes to "see." Cattaneo and Vecchi address critical questions of broad importance: the relationship of visual perception to imagery and working memory and the extent to which mental imagery depends on normal vision; the functional and neural relationships between vision and the other senses; the specific aspects of the visual experience that are crucial to cognitive development or specific cognitive mechanisms; and the extraordinary plasticity of the brain—as illustrated by the way that, in the blind, the visual cortex may be reorganized to support other perceptual or cognitive funtions. In the absence of vision, the other senses work as functional substitutes and are often improved. With Blind Vision, Cattaneo and Vecchi take on the "tyranny of the visual," pointing to the importance of the other senses in cognition.

"Access Technology for Blind and Low Vision Accessibility, the second edition of 2008's Assistive Technology for Students Who Are Blind or Visually Impaired: A Guide to Assessment, uses clear language to describe the range of technology solutions that exists to facilitate low vision and nonvisual access to print and digital information. Part 1 gives teachers, professionals, and families an overview of current technologies including refreshable braille displays, screen readers, 3D printers, cloud computing, tactile media, and integrated development environments. Part 2 builds on this foundation, providing readers with a conceptual and practical framework to guide a comprehensive technology evaluation process. As did its predecessor, Access Technology for Blind and Low Vision Accessibility is focused on giving people who are blind or visually impaired equal access to all activities of self-determined living, allowing them to be seamlessly integrated within their home, school, and work communities"--

This is an inspirational memoir of a man who not only recovered from his Viet Nam War wounds that blinded him but from the force of darkness of self-pity, frustration, despair, and tragedy but thrived with a positive mindset and the principles for inspired living.

Foundations of Low Vision: Clinical and Functional Perspectives, the ground-breaking text that highlighted the importance of focusing on the functional as well as the clinical implications of low vision, has been completely updated and expanded in this second edition. The revised edition goes even further in its presentation of how best to assess and support both children and adults with low vision and plan programs and services that optimize their functional vision and ability to lead productive and satisfying lives, based on individuals' actual abilities. Part 1, Personal and Professional Perspectives, provides the foundations of this approach, with chapters focused on the anatomy of the eye, medical causes of visual impairment, optics and low vision devices, and clinical low vision services, as well as psychological and social implications of low vision and the history of the field. Part 2 focuses on children and youths, providing detailed treatment of functional vision assessment, instruction, use of low vision devices, orientation and mobility, and assistive technology. Part 3 presents rehabilitation and employment issues for working-age adults and special considerations for older adults.

In this unique and exhilarating autobiography, Allan Jones – Canada’s first blind diplomat – vividly describes how an untreatable eye disease slowly decimated his visual world, most challengingly during his postings in Tokyo and New Delhi, and how he discovered and took to heart the revelatory Indian philosophy that changed his life. Advaita Vedanta, the most iconoclastic and liberating of the classical Indian philosophies, profoundly altered the author’s experience of self and world. He found that the true self, as distinct from the individual ego, far exceeds the boundaries of individuality. It lies beneath sightedness or blindness and is absolutely unaffected by the latter. This welcome shift of perspective was reinforced by startling discoveries in contemporary physics, evolutionary biology, and developmental psychology that are fully consistent with Advaitic metaphysics. As for the practical applications of metaphysics, this book demonstrates step by step how Advaitic insight and practice significantly reduce physical and psychological tension. The most telling examples have to do with adjustments compelled by extreme circumstances. Thus Jones describes how he drew upon Advaitic mindfulness techniques to maintain his white cane mobility skills in the teeth of permanent spinal, nerve, and muscle pain. The arc of Beyond Vision moves from the claustrophobically personal to the openness of the transpersonal. It begins in a dysfunctional family background, breaking out into a full life encompassing an adventurous foreign service career, spiritual exploration, and an unconventional kind of marital love.

Cerebral visual impairment (also known as cortical visual impairment, or CVI) has become the most common cause of visual impairment in children in the United States and the developed world. Vision and the Brain is a unique and comprehensive sourcebook geared especially to professionals in the field of visual impairment, educators, and families who need to know more about the causes and types of CVI and the best practices for working with affected children. Expert contributors from many countries represent education, occupational therapy, orientation and mobility, ophthalmology, optometry, neuropsychology, psychology, and vision science, and include parents of children with CVI. The book provides an in-depth guide to current knowledge about brain-related vision loss in an accessible form to enable readers to recognize, understand, and assess the behavioral manifestations of damage to the visual brain and develop effective interventions based on identification of the spectrum of individual needs. Chapters are designed to help those working with children with CVI ascertain the nature and degree of visual impairment in each child, so that they can "see" and appreciate the world through the child's eyes and ensure that every child is served appropriately.

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.
