Overview

Visual Impairment: A Global View is a multidisciplinary introduction to eye defects and diseases and explains how many of these potentially disabling conditions can be overcome or ameliorated by inexpensive technologies. To understand the problems of defective sight in depth, the book explains the structure of the eye, the physical properties of light, how an image is formed on the retina, and the molecular basis of colour vision. The case study then turns to ways of correcting or improving vision.
