Self-reported	0.44 [0.40, 0.49]	0.47 [0.31, 0.60]	0.36 [0.20, 0.50]	0.58 [0.42, 0.71]	0.47 [0.43, 0.51]
20/80 – 20/31	0.56 [0.51, 0.61]	0.45 [0.35, 0.54]	0.51 [0.39, 0.62]	0.38 [0.32, 0.44]	0.48 [0.44, 0.51]
20/30 or above	0.63 [0.54, 0.71]	0.43 [0.30, 0.54]	0.49 [0.39, 0.59]	0.43 [0.36, 0.49]	0.50 [0.46, 0.54]
Overall	0.52 [0.50, 0.55]	0.45 [0.42, 0.48]	0.45 [0.41, 0.48]	0.47 [0.44, 0.50]

Note. Average effect sizes (r) and 95% confidence intervals (in brackets) are presented as a function of the five visual acuity criteria and four cognitive domains. Overall values were calculated for each visual acuity criteria by collapsing across the cognitive domains and vice versa.
