Table 1 Mean values for the disturbance index, pupil size and MTF-cutoff.

From: A visual test based on a freeware software for quantifying and displaying night-vision disturbances: study in subjects after alcohol consumption

  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
  1. 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.
