Prevalence and Causes of Blindness and Visual Impairment in Canada

Abstract

This article presents the findings of the most comprehensive Canadian survey on disabilities, the 1986 postcensus Health and Activity Limitation Survey, which analyzed data on blindness and visual impairment. An examination of vision loss and its prevalence in the general population by age group and within the disabled population uncovered some new variations in statistics on prevalence rates and some new information on age at onset, cause of vision loss, and the severity of visual impairment.
