An understanding of the fundamental principles of geometrical and physical optics is essential for any student engaged in the study of the visual sciences, but the non-physicist needs a text which clearly explains these notoriously difficult concepts in order to apply them to the practical and clinical aspects of vision. Optics by Freeman and Hull fulfils this requirement admirably. Comprehensive information on optics makes this book the definitive source on the subject. A bright, two-color design enhances the text and aids the reader's understanding. Completely updated and revised to present the latest information in the field. All illustrations are now highlighted with a second color to aid understanding. A new color plate section provides clear, excellent-quality photographs to vividly illustrate important concepts. More information is included on aspheric lenses, with a new chapter on aspheric lenses. Many new questions and exercises reinforce important points and help readers understand the material. The contents have been entirely reorganized for a more logical, easy-to-follow approach. A new glossary defines all key terms from the chapters for convenient reference.

Completely revised and updated, you will benefit from new and rewritten sections on: axial magnification Jackson Cross Cylinder tests retinoscopy reflex motions field of view the optics of indirect ophthalmoscopy optical aberrations diffractive lenses the Doppler shift lasers and the similarities and differences of Gaussian laser beams versus the propagation of light from a point source plus, a new appendix on angles and basic trigonometry. Although not a matrix optics text, matrices are used extensively in the chapters on spherical systems and off-axis aspects of astigmatism. In particular, the matrix treatment of astigmatism serves as a foundation for the recently developed, much improved statistical techniques that deal with refractive corrections and astigmatism in all its aspects. * Emphasizes conceptual understanding and development of optical intuition * Uses the vergence-dioptric power-wavefront approach * Helpful review for optometry boards and qualifying examinations

The book is divided into a number of short chapters with each chapter dedicated to a single theme. For ease of reference, the most commonly useful topics are at the beginning and topics with narrower appeal, such as ocular aberrations, are placed towards the end. The book is divided into 5 sections, covering: * basic optical structure of the human eye * image formation and refraction of the eye (including refractive errors of the eye, measurement and correction) * interactions between light and the eye, considering transmission, reflection and scatter in the media of the eye and at the fundus * aberrations and retinal image quality * depth of field copics and age related changes in the optics of the eye The book concludes with 4 appendices, covering mathematics relating to paraxial optics, aberrations theory and image quality criteria and construction data, optical parameters and the aberrations of a number of schematic eyes. * A primer for all students of optometry and vision sciences covering optics of the normal eye and introducing them to refractive problems * * Presented in a clear and succinct style with a friendly approach, this book provides and up-to-date coverage of the aberrations and image quality of the eye

This book contains all oral presentations, posters, and workshop transactions of the 28th Meeting of the European Strabismological Association that took place in Bergen, Norway.

In the last few years there have been many papers in vision science journals about visual factors in dyslexia, but these findings have not been widely disseminated to the professionals who care for people with dyslexia. Dyslexia and Vision aims to provide a straightforward summary of work in this field for teachers, educational psychologists, child psychologists, and paediatricians. The primary purpose of the book is to provide these professionals with the information they need in order to offer balanced, insightful advice for people in their care. Eyecare professionals themselves are often bewildered by the plethora of claims and anecdotes in this field. A secondary purpose of the book is to provide, in appendices, a balanced "evidence-based" review of the literature for eyecare professionals.

The surgical correction of refractive vision errors has dramatically and continually changed over time. The evolution of laser vision correction has been aided by advancements in the technology, growing experience, and improved understanding of the eye and its response to surgery. However, not all refractive errors can be treated with the laser. Phakic IOLs: State of the Art is designed to provide the advances in phakic IOL technology and techniques, ideal for physicians who treat many of the patients who are not candidates for laser vision correction. The collaboration of Dr. Lucio Buratto, Dr. Stephen G. Slade, and Dr. Nicola D. Hauranieh, along with a team of international surgeons, has produced a complete book specifically aimed to improve the treatment and therefore the quality of vision of patients. Phakic IOLs: State of the Art is designed for ophthalmologists interested in learning the concepts, developing the skills, and preparing for phakic IOL procedures. This book contains a detailed description of the basic technique of the operations, as well as the special techniques devised by the international contributors. Richly illustrated with over 200 images that demonstrate the various concepts, readers are able to develop a more thorough understanding of phakic IOL implantation. This definitive resource couples both the authors’ and contributors’ diverse experience and knowledge to produce a complete resource of vision correction with phakic IOLs. Expert ophthalmologists interested in being on the cutting edge and enhancing their surgical skills, as well as new physicians, will benefit from adding Phakic IOLs: State of the Art to their personal library.

Developing healthy visual-motor abilities is more difficult in the complex stimulus of today's world than ever before. Our visual experiences can be overwhelmed by the vast complexity of artificial colors and sounds which did not exist in our ancestors' lives. Much more time is spent indoors, exposed to a myriad of unnatural colors, movement and imagery. We hibernate inside, interacting with machines instead of being out in the sunlight, looking at the far horizons, exploring natural environments. More and more time is spent sitting rather than moving, watching rather than doing. Here is a book that has: An overview of the development of vision, with a checklist of warning signs of vision problems-based on the studies of behavioral optometry; A discussion of the importance of integrating all the senses equally in the development of optimal visual skills, rooted in the field of occupational therapy; Practical, playful activities designed to improve visual skills in both adults and children. Excellent for use at home, in the clinic, at school, or amid outdoor settings
