Although global age-standardised DALY rates remained statistically stable between 1990 and 2021, regional trends varied numerically. Southern sub-Saharan Africa recorded the highest age-standardised prevalence rate in 2021 at 16\u2009741.4 (13\u2009187.8\u201321\u2009129.5), whereas the highest DALY rate was observed in South Asia at 497.1 (345.3\u2013691.6). While the overall burden of blindness did not differ significantly by sex, glaucoma showed a higher burden in males. From 1990 to 2021, cataract DALY rates attributable to household air pollution decreased by 38.4%, with projections showing stable age-standardised rates through 2050.<\/jats:p>\n
