Prevalence of blindness (
presenting VA of less than 3/60 in the better eye) was 4.1 (95 confidence interval CI, 3.44.8); prevalence of low vision (presenting VA of at least 3/60 but less than 18/60 in the better eye) was 7.7 (95 CI, 6.78.7); whereas prevalence of monocular visual impairment (presenting VA of at least 18/60 in better eye and VA of less than 18/60 in other eye) was 4.4 (95 CI, 3.65.3).
