Most people rely more heavily on their sight than on any of their other senses for their day to day interactions with the environment. This is reflected in our vocabulary: if something is well-explained we might exclaim "I see!"; someone who has exciting ideas might be described as'visionary'. Asked which sense we most fear using, the majority of us will put sight at the top of our list.Visual Impairment - A Global View shows how, through an understanding of the anatomy and physiology of the eye, sight can be saved. After exploring the physical basis of light, and the structure of the eye and how it interacts with light, the book goes on to examine the causes of visual impairment.These causes, such as cataracts, may be linked to the ageing process, but may also be a consequence of infection - a significant issue in many of the poorest regions of the world.The book is supported by a fully interactive DVD. This DVD features 'The eye' and 'Optics of the lenses and the eye', which combine animations and graphics; and two videos, 'Effective interventions in visual impairments' and 'Transmission of eye infections between children at play'.The Online Resource Centre features:For lecturers who are registered adopters of the book:- Figures from the book in electronic format, available to downloadFor students:- Access to ROUTES, a searchable internet database of online resources compiled by academic staff and subject-specialist librarians.
