Mean differences in contrast sensitivity between full correction and spherical equivalent correction (N = 38)

Contrast sensitivity condition	Mean differencea ± SEM (logMAR)
	3 cpd	6 cpd	12 cpd	18 cpd
Photopic without glare	0.008 ± 0.04	0.01 ± 0.04	0.01 ± 0.06	0.02 ± 0.05
Mesopic without glare	−0.05 ± 0.05	0.12 ± 0.06b	0.03 ± 0.06	0.02 ± 0.05
Mesopic with glare	0.02 ± 0.04	0.03 ± 0.05	0.03 ± 0.045	0.07 ± 0.04

Notes:

^aMean difference = score with full correction – score with spherical equivalent correction;

^bP = 0.046.

Abbreviations: cpd, cycles per degree; logMAR, logarithm of the minimum angle of resolution; SEM, standard error of the mean.
