Book Description
Aging research on the human eyes crosses all areas of ophthalmology and also relies upon biological, morphological, physiological, and biochemical tools for its study. This book reviews all aspects of human eye aging. In addition to descriptions of age-related changes in almost all the structures of the human eyes, the authors also include interesting accounts of personal experiments and data. It provides an extensive panorama of what happens during aging in the eye.

Book Description
This book describes the optical structure and optical properties of the human eye. For ease of reference, the most commonly useful topics are at the beginning and topics with narrower appeal are placed towards the end. The book is divided into five sections, covering: Basic optical structure of the eye, including the refracting components, the pupil, axes, and simple models of the eye Image formation and refraction of the eye, including refractive errors, measurement, and correction Interactions between light and the eye, considering transmission, reflection, and scatter in the media and at the fundus Aberrations and retinal image quality Depth-of-field and age-related changes in the optics of the eye There have been many developments in the field of visual optics since the first edition was published in 2000. There have been advances in instrumentation for imagery, biometry, and aberrations of the eye. The refraction anomaly of myopia has increased in prevalence throughout the world, and is getting increasing attention because of its association with ocular pathology in the middle and later years of life. Ocular aberrations are now considered in terms of Zernike polynomials rather than Taylor polynomials. Aberrations can be manipulated to better understand their effects on visual performance to improve imagery of the retina for the betterment of diagnosis of various ocular conditions, and to treat the progression of myopia in children. To deal with these developments, the section on aberrations and retinal image quality has undergone considerable revision. This book will be an invaluable purchase for all those with an interest in vision, such as optometrists, ophthalmologists, vision scientists, optical physics, and student of visual optics. An understanding of the optics of the human eye is particular important to designers of ophthalmic diagnostic equipment and visual optical systems such as telescopes.

Book Description
The purpose of this dissertation was to objectively quantify changes in the lens and ciliary body of the human eye in vivo in a single cohort of patients, before, during and after onset of presbyopia. This was achieved through the development of optical coherence tomography and magnetic resonance imaging techniques and computer-based image segmentation programs.

Book Description
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.

Book Description
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.

Book Description
Drs. Paul L. Kaufman, Albert Alm, Leonard A Levin, Siv F. E. Nilsson, James Ver Hoeve, and Samuel Wu present the 11th Edition of the classic text Adler’s Physiology of the Eye, updated to enhance your understanding of ocular function. This full-color, user-friendly edition captures the latest molecular, genetic, and biochemical discoveries and offers you unparalleled knowledge and insight into the physiology of the eye and its structures. A new organization by function, rather than anatomy, helps you make a stronger connection between physiological principles and clinical practice; and more than 1,000 great new full-color illustrations help clarify complex concepts. Deepen your grasp of the physiological principles that underlie visual acuity, color vision, ocular circulation, the extraocular muscle, and much more. Glean the latest knowledge in the field, including the most recent molecular, genetic, and biochemical discoveries. Make a stronger connection between physiology and clinical practice with the aid of an enhanced clinical emphasis throughout, as well as a new organization by function rather than by anatomy. Better visualize all concepts by viewing 1,000 clear, full-color illustrations.
