Vision Facts is a question and answer guide to the wonders of the human eye, its complex structures and the process of visual perception. It traces the journey of vision from a ray of light entering the eye to the processing done by the brain, to the development and aging of the human visual system and common disorders associated with both processes. Organized in an intuitive question-and-answer format and accompanied by clear diagrams, Vision Facts provides answers regarding your vision in a manner accessible to all who are interested. Each topic includes references to external resources such as lecture notes and research papers for those who wish to delve deeper. It is a perfect handbook for anyone who is interested in visual science, sensory processing, neuroscience, or physiology; and is an excellent reference for anyone considering a career in ophthalmology or optometry. Some examples of the questions include the following. What is the resolution of the eye? Why do astronomers often cover flashlights with a red filter while stargazing? What is color-blindness and how does it occur? What role does vision play in the circadian rhythm? What chemical signals cause the eye to develop into its mature form? How does alcohol during pregnancy affect eye development? How well can a newborn baby see? How does being born prematurely affect vision? What is 20/20 vision? How does aging affect vision? These are all questions that are addressed in Vision Facts, along with countless more.

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 eye is one of the most remarkable achievements of evolution, and has evolved up to 40 times in different parts of the animal kingdom. In humans, vision is the most important sense, and much of the brain is given over to the processing of visual information. In this Very Short Introduction, Michael Land describes the evolution of vision and the variety of eyes found in both humans and animals. He explores the evolution of colour vision in primates and the workings of the human eye, to consider how that contributes to our visual ability. He explains how we see in three dimensions and the basic principles of visual perception, including our impressive capacity for pattern recognition and the ability of vision to guide action. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

More than 180 million Americans have a problem with their vision. Most believe there's not much they can do on their own to change how much (or how little) they see. Now there is hope. In the past decade, an overwhelming number of clinical studies have shown that eating specific nutrients can help maintain vision well into old age, alleviate eye conditions, and even reverse the progress of diseases. In this book, top ophthalmologist Dr. Neal Adams uses clear, accessible language to translate research from hundreds of clinical studies in ophthalmology and nutrition to show how we can restore and maintain eyesight by changing our diet. The solution is simple: just naturally grown foods, with nutrients clinically proven to target the components of the eye affected by disease and/or age. The book explains how the eye functions and what nutrients influence these physiological processes, and includes tailored, easy-to-understand instruction on which foods and nutrients will target the reader's specific concerns. Particularly helpful for the 150 million Americans who visit their eye doctors annually as well as the 95 percent of Americans over 40 at risk for future vision loss.
