The effect of relatively low doses of alcohol on recovery times following bright light exposure was studied. Nine male subjects (aged from 20 to 28) participated in a replicated 3 X 3 crossover experiment run double blind. The alcohol induced increase in recovery time is apparent in the first 30 minutes, peaks at the 1-2 hour point, and declines to reach predrink values approximately 6 hours after drinking. Relatively low doses of alcohol produce significant dose-related delays in recovery of contrast sensitivity following exposure to intense light levels. Since pupil size and visual acuity has been shown to be relatively independent of alcohol doses, the authors are satisfied that they have demonstrated that the delays in glare recovery occur at the retinal level, are dose-related and are produced by low BALs (approximately one cocktail on an empty stomach).
