Basic Vision

If you've ever been tricked by an optical illusion, you'll have some idea about just how clever the relationship between your eyes and your brain is. This book leads one through the intricacies of the subject and demystifying how we see.

Basic and Clinical Applications of Vision Sciences contains the edited papers presented at the Enoch Vision Science Symposium, April 27-30 1996, which was organized in honor of the pioneer in vision science, Dr Jay M Enoch. Dr Enoch served for twelve years as Dean, School of Optometry, University of California, Berkeley. The book is organized along the lines of Dr. Enoch's contributions to vision science, but is not limited to these topics. Of special note, the reader will find papers on important new developments in photoreceptor, ophthalmic and visual optics, retinal imaging, ophthalmic physiology and pathophysiology, visual psychophysics and visual techniques. The papers are grouped into the following sections: photoreceptor optics; ophthalmic and visual optics; binocular vision, developmental vision, eye movements and physiology; ophthalmic dysfunction; visual psychophysics and clinical applications; history of vision science. £/LIST£

I have been asked to write a brief foreword to this volume honoring Hisako Ikeda, providing a review of the accomplishments in our field over the past four decades, when Hisako was an active participant. This I am delighted to do. It has been a most exciting time in vision research and Hisako has been right in the middle of much of the excitement, publishing on a wide variety of topics and providing much new data and many new insights. Hisako's research career can be divided by decades into four quite distinct areas of inquiry. In the 1950s, as a student in Japan, her research interests were psychophysical in nature, and she was concerned with visual illusions, figural aftereffects, and motion detec tion. In the 1960s, after her move to London, she began electrophysiological studies. Much of her work in the 1960s was concerned with the electroretinogram (ERG), its components, and the use of this electrical response for evaluating spectral sensitivities of the eye and retinal degenerations. This work represented the beginning of her electrodiagnostic clinical work, which continued until her retirement.

The present publication constitutively expands the field of discourse on the topic of basic income and explores the possibilities of its introduction as well as the opportunities and risks. Although all visionary proposals for an unconditional basic income (BGE) have so far not been implemented politically, at least in democratically constituted welfare states, the question of implementation or the conditions for success and the identification of possible blockades have only been dealt with marginally. Recent publications on a BGE also show this political-institutional "blindness" and do not address enough the reasons for the failure so far. Without a transfer strategy, however, the idea will fail in Germany due to such implementation naivety. In this book, therefore, the state of the debate on basic income is developed further to the extent that it is integrated into welfare-state development processes and current challenges for the "safeguarding of social security". In addition, a social-scientific classification of hitherto visionary guarantee elements of a basic income model is undertaken, linking up with the "silent" change to a socially investing state.

Emphasizing the need for collaboration and cooperation across medical, education, rehabilitation, and social service disciplines, this volume provides a primary reference tool for those engaged in work related to low vision rehabilitation and service delivery. It provides information about the funct.

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.

Clearly organized and simply presented, The Low Vision Handbook for Eyecare Professionals, Second Edition offers an introduction to all aspects of low vision, including a short history of low vision and the basic optics of magnifiers. Updated and revised this second edition of The Low Vision Handbook for Eyecare Professionals provides practical material on assessing low vision patients, the psychology of visual loss, and ways to alleviate patients’ common fears. Additionally, Barbara Brown explores current optical, nonoptical, and electronic devices and their appropriate uses for various patients. Additional features include: Case histories to explain some differences among patients at varying levels of vision loss Key points and study icons that highlight topics of interest for paraprofessionals studying for their certification exams Addresses and websites for vendors of low vision aids and devices Contact information for rehabilitation centers and support agencies to benefit visually impaired patients Multiple references and resources for further study The Low Vision Handbook for Eyecare Professionals, Second Edition is perfect for students of the ophthalmic and optometric sciences, introductory-level assistants and other medical office staff, as well as more experienced technicians. The easy-to-read format, user-friendly terminology, and resource information make it an invaluable book for all who assist low vision patients.

The 4-volume set LNCS 13019, 13020, 13021 and 13022 constitutes the refereed proceedings of the 4th Chinese Conference on Pattern Recognition and Computer Vision, PRCV 2021, held in Beijing, China, in October-November 2021. The 201 full papers presented were carefully reviewed and selected from 513 submissions. The papers have been organized in the following topical sections: Object Detection, Tracking and Recognition; Computer Vision, Theories and Applications, Multimedia Processing and Analysis; Low-level Vision and Image Processing; Biomedical Image Processing and Analysis; Machine Learning, Neural Network and Deep Learning, and New Advances in Visual Perception and Understanding.
