Deals with the history of eyeglasses from their invention in Italy ca. 1286 to the appearance of the telescope three cent. later. "By the end of the 16th cent. eyeglasses were as common in western and central Europe as desktop computers are in western developed countries today." Eyeglasses served an important technological function at both the intellectual and practical level, not only easing the textual studies of scholars but also easing the work of craftsmen/small bus. During the 15th cent. two crucial developments occurred: the ability to grind convex lenses for various levels of presbyopia and the ability to grind concave lenses for the correction of myopia. As a result, eyeglasses could be made almost to prescription by the early 17th cent. Illus.
This is the first full-length study of spectacles in the Victorian period. It examines how the Victorians shaped our understanding of functional visual capacity and the concept of 20:20 vision. Demonstrating how this unique assistive device can connect the histories of medicine, technology and disability, it charts how technology has influenced our understanding of sensory perception, both through the diagnostic methods used to measure visual impairment and the utility of spectacles to ameliorate its effects. Taking a material culture approach, the book assesses how the design of spectacles thwarted ophthalmologists’ attempts to medicalise their distribution and use, as well as creating a mainstream marketable device on the high street.
This book has been designed to offer expert information to the eye care practitioners so that they can guide and provide basic low vision care to each patient in their small step up. A user-friendly book helps to encourage the optometrists and ophthalmologists to recognize the importance of low vision devices enabling the partially-seeing patient to utilize their remaining vision to its full potential. Contains information to understand the meaning of visual acuity in relation to normal vision low vision and blindness; to identify people with low vision as distinct from those who have normal v.
When Ralph Waldo Emerson wrote in 1837 that "Our Age is Ocular," he offered a succinct assessment of antebellum America's cultural, commercial, and physiological preoccupation with sight. In the early nineteenth century, the American city's visual culture was manifest in pamphlets, newspapers, painting exhibitions, and spectacular entertainments; businesses promoted their wares to consumers on the move with broadsides, posters, and signboards; and advances in ophthalmological sciences linked the mechanics of vision to the physiological functions of the human body. Within this crowded visual field, sight circulated as a metaphor, as a physiological process, and as a commercial commodity. Out of the intersection of these various discourses and practices emerged an entirely new understanding of vision. The Commerce of Vision integrates cultural history, art history, and material culture studies to explore how vision was understood and experienced in the first half of the nineteenth century. Peter John Brownlee examines a wide selection of objects and practices that demonstrate the contemporary preoccupation with ocular culture and accurate vision: from the birth of ophthalmic surgery to the business of opticians, from the typography used by urban sign painters and job printers to the explosion of daguerreotypes and other visual forms, and from the novels of Edgar Allan Poe and Herman Melville to the genre paintings of Richard Caton Woodville and Francis Edmonds. In response to this expanding visual culture, antebellum Americans cultivated new perceptual practices, habits, and aptitudes. At the same time, however, new visual experiences became quickly integrated with the machinery of commodity production and highlighted the physical shortcomings of sight, as well as nascent ethical shortcomings of a surface-based culture. Through its theoretically acute and extensively researched analysis, The Commerce of Vision synthesizes the broad culturing of vision in antebellum America.
The Eye in History is a comprehensive manual describing the structure and function of the eye, ocular disorders and their treatment. Beginning with an introduction to anatomy and discussion on different disorders, the authors also review eye diseases of famous historical people and perception differences between men and women. The final sections discuss eye surgery and future technologies including the bionic eye, nanotechnology and gene therapy. Edited by Frank Joseph Goes of the Goes Eye Centre in Belgium, this multi-authored book has contributions from specialists throughout Europe, as well as the USA. 830 full colour images and illustrations assist comprehension.

'Elegant and multi-focal. Glorious!' Simon Garfield 'It will make you look at specs with fresh eyes' New Statesman 'Lively, engaging and admirably wide-ranging' The Times 'Fascinating' Observer The humble pair of glasses might just be one of the world's greatest inventions, allowing millions to see a world that might otherwise appear a blur. And yet how much do many of us really think about these things perched on the ends of our noses? Through the Looking Glasses traces the fascinating story of spectacles: from their inception as primitive visual aids for monkish scribes right through to today's designer eyewear and the augmented reality of Google Glass. There are encounters with ingenious medieval Italian glassmakers, myopic Renaissance rulers and spectacle-makers, as well as the silent movie star Harold Lloyd, the rock'n'roller Buddy Holly and the full-screen figure of Marilyn Monroe. This is a book about vision and the need for humanity to see clearly, and where the impulse to improve our eyesight has led us.
In recent years we have become interested in the diffusion of “small” Western technologies in the countries of the Middle East during the 19th and 20th centuries, the era of Imperialism and first globalization. We postulated a contrast between “small” and “big” technologies. Under the latter category we may understand railway systems, electricity grids, telegraph networks, and steam navigation, imposed by foreign powers or installed by connected local entrepreneurs. But many “small” Western technologies, such as sewing machines, typewriters, pianos, eyeglasses, and similar consumer goods, which had been developed and manufactured in Europe and America, were wanted, and willingly acquired by the agency of individual users elsewhere. In a few cases, however, the inventions had to be adapted, or were overstepped, and even delayed. Some were adopted as social markers or status symbols only by elites who could afford them. Processes of adoption and diffusion therefore differed according to cultural settings, preferences, and needs. Social and cultural historians, and social scientists, not only of the Middle East, will find in this collection of essays a new approach to the impact of Western technological inventions on the Middle East.
