The Prevalence and Consequences of Vision Impairment in Later Life

This article reviews the research literature regarding the prevalence and consequences of age-related vision impairment. Prevalence estimates vary depending upon whether vision impairment is based on self-report data or clinical assessments, and range from approximately 4% to 20% of adults aged 65 and older. Differences in estimates are discussed in terms of the different information they provide. Recent research highlights that vision impairment in later life can have profound consequences for the physical functioning, psychological well-being, and health service needs of older adults. Vision rehabilitation services that can address such consequences are described, and there is growing evidence on their effectiveness in combating excess disability and enhancing psychological well-being among older adults.
