  • Title: Visual functions and acute ingestion of alcohol.
    Author: Watten RG, Lie I.
    Journal: Ophthalmic Physiol Opt; 1996 Nov; 16(6):460-6. PubMed ID: 8944192.
    Abstract:
    In a placebo-controlled experiment comprising 22 healthy men (mean age 27.4 years), we investigated the influence of three breath levels of blood alcohol (BrAC; 0.0%, 0.05% and 0.1%) upon distant visual acuity, stereoacuity, contrast sensitivity, accommodation, resting focus of accommodation and binocular vision. Positive (PRA) and negative accommodation (NRA) and resting focus of accommodation showed no significant changes with increasing BrAC. Compared to the placebo condition, visual acuity and refraction were only significantly affected at a breath alcohol level of 0.1%. Contrast sensitivity, stereoacuity and binocular vision were affected both at BrAC 0.05% and BrAC 0.1%. Only the higher spatial frequencies of contrast sensitivity were affected.
