Mean values for the disturbance index, pupil size and MTF-cutoff.

	PRE-	POST-	Goggles	p-value
VDI monocular	0.25 ± 0.15	0.39 ± 0.24	-	<0.001
VDI binocular	0.16 ± 0.08	0.26 ± 0.16	0.95 ± 0.05	<0.001
Pupil size (mm)	5.3 ± 0.9	5.6 ± 1.0	-	<0.001
MTF-cutoff (cpd)	40 ± 11	35 ± 12	-	<0.001

Mean values for the visual disturbance index (VDI), monocular and binocular, under different experimental conditions before (pre) and after (post) alcohol consumption and wearing alcohol-impairment goggles (only binocular). Mean values of the pupil size and MTF-cutoff are also showed. Standard deviation included. Statistical analysis: paired-sample t-Test for means.
