BE Better-seeing eye, WE Worse-seeing eye, VI Vision impairment; no VI: < 0.32 logMAR, mild VI: 0.32–0.5 logMAR; moderate/severe VI: > 0.5 logMAR); all models adjusted for age and sex using both eyes with no VI as a reference; model 1b additionally adjusted for socioeconomic status; CI: 95% confidence interval; a: p < 0.0001, R2: adjusted R2
