^*Non-resolving: visual impairment by best measured as well as presenting visual acuity. Resolving, with refractive error: resolved during retesting protocol (Figure 1), with significant uncorrected refractive error at presentation: spherical equivalent (SE) hyperopia 3.0 diopter (D) or more, SE myopia 0.5 D or more, astigmatism 2.0 D or more at any age, or astigmatism 1.5 D or more for children >36 months of age.

^**CI: 95% confidence interval; calculated for total visual impairment in each age category.
