Download or read book Basic and Clinical Perspectives in Vision Research written by Jon G. Robbins and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Making Eye Health a Population Health Imperative written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-01-15 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book If the Walls of My Exam Room Could Talk written by Debby Feinberg and published by . This book was released on 2013-02-09 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Who would have thought that a basic eye alignment problem could cause a person to be miserable or disabled? Yet that is exactly what is happening with Vertical Heterophoria (VH), a visual condition where there is a slight vertical image misalignment which causes headaches, dizziness, anxiety, neck pain and reading difficulties. Using techniques developed by Dr. Debby Feinberg, patients are fit with prism eyeglass lenses that realign the images, resulting (on average) in an 80% reduction of symptoms. This book contains the stories of those suffering from VH, their difficult journey through life and the medical system, and their recovery and return to health using just a simple pair of properly prescribed prism lenses."Who, indeed, could have supposed that a mere ocular defect could have given rise to so serious a train of evils...and who that had not seen it, could believe that the correction by glasses of the eye trouble could have given a relief so speedy and so perfect that the patient described it as a miracle?" Dr. S. Weir Mitchell, Neurologist and Headache Specialist Philadelphia, PA Headaches and Eye Strain, April 1876

Download or read book Vision written by David Marr and published by MIT Press. This book was released on 2010-07-09 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: Available again, an influential book that offers a framework for understanding visual perception and considers fundamental questions about the brain and its functions. David Marr's posthumously published Vision (1982) influenced a generation of brain and cognitive scientists, inspiring many to enter the field. In Vision, Marr describes a general framework for understanding visual perception and touches on broader questions about how the brain and its functions can be studied and understood. Researchers from a range of brain and cognitive sciences have long valued Marr's creativity, intellectual power, and ability to integrate insights and data from neuroscience, psychology, and computation. This MIT Press edition makes Marr's influential work available to a new generation of students and scientists. In Marr's framework, the process of vision constructs a set of representations, starting from a description of the input image and culminating with a description of three-dimensional objects in the surrounding environment. A central theme, and one that has had far-reaching influence in both neuroscience and cognitive science, is the notion of different levels of analysis—in Marr's framework, the computational level, the algorithmic level, and the hardware implementation level. Now, thirty years later, the main problems that occupied Marr remain fundamental open problems in the study of perception. Vision provides inspiration for the continuing efforts to integrate knowledge from cognition and computation to understand vision and the brain.

Download or read book The Bates Method for Better Eyesight Without Glasses written by William H. Bates and published by Holt Paperbacks. This book was released on 2011-04-01 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Better Eyesight Without Glasses is not only the definitive source for the classic Bates Method, it is in itself a remarkable phenomenon. Dr. William H. Bates’s revolutionary and entirely commonsensical theory of self-taught improved eyesight has helped hundreds of thousands of people to triumph over normal defects of vision without the mechanical aid of eyeglasses. If you think that your eyesight could be made better by natural methods, you are right. After years of experimentation, Dr. Bates came to the conclusion that many people who wore glasses did not need them. He gradually and carefully developed a simple group of exercises for improving the ability of the eyes themselves to see, eliminating the tension caused by poor visual habits that are the major cause of bad eyesight. These exercises are based on the firm belief that it is the natural function of the eyes to see clearly and that anyone, child or adult, can learn to see better without glasses.
Download or read book Machine Vision written by Fabio Solari and published by BoD – Books on Demand. This book was released on 2012-03-23 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vision plays a fundamental role for living beings by allowing them to interact with the environment in an effective and efficient way. The ultimate goal of Machine Vision is to endow artificial systems with adequate capabilities to cope with not a priori predetermined situations. To this end, we have to take into account the computing constraints of the hosting architectures and the specifications of the tasks to be accomplished, to continuously adapt and optimize the visual processing techniques. Nevertheless, by exploiting the low?cost computational power of off?the?shell computing devices, Machine Vision is not limited any more to industrial environments, where situations and tasks are simplified and very specific, but it is now pervasive to support system solutions of everyday life problems.

Available in PDF, EPUB and Kindle. Book excerpt: "The Aravind Eye Hospital, based in India, is the world's largest provider of high-quality eye care. It is also one of the world's most incredible and revolutionary organizations - delivering surgical outcomes equal to or exceeding those in the developedworld at less than one percent of the cost, treating more than half of its patients free of charge, and taking no grants or donations. Aravind's success is so perplexing it has been the subject of a popular Harvard Business School case study. This is thefirst book to explore Aravind's history and the distinctive philosophies, practices, and commitments that are the keys to its success. Mehta and Shenoy share incredible stories about how Aravind grew from humble beginnings--founded by a retired ophthalmologist with no money or prior entrepre-neurial experience--to the world-class organization it is today. They explain the mysteries of a model that integrates innovation with empathy, service with business principles, and inner change with outer transformation. And they show how choices that seem foolish and unworkable can, when executed with compassion and integrity, yield powerful results - results that literally light the eyes of millions."--Provided by publisher.
