Abstract: The aim of this study was to assess contrast sensitivity for angular frequency stimuli as well as for sine-wave gratings in adults under the effect of acute ingestion of alcohol. We measured the contrast sensitivity function (CSF) for gratings of 0.25, 1.25, 2.5, 4, 10, and 20 cycles per degree of visual angle (cpd) as well as for angular frequency stimuli of 1, 2, 4, 24, 48, and 96 cycles/360°. Twenty adults free of ocular diseases, with normal or corrected-to-normal visual acuity, and no history of alcoholis… Show more

“…We found that some aspects of colour vision such as the ability to perform the arrangement of series of different hues and the colour discrimination thresholds were affected in sporadic young alcohol consumers. Although previous studies described a profound effect of alcohol consumption on visual functions of adults with prolonged chronic exposure to ethanol [ 10 18 , 20 ], the present study was the first to demonstrate that young people with low frequency of alcohol consumption exhibit significant colour vision impairment. This study also demonstrated that colour vision was more vulnerable to the alcohol effect than luminance spatial contrast sensitivity in young people.…”

“…It was well documented that precocious alcohol consumption could lead to chemical dependence in both young and adult subjects [ 6 9 ]. Besides socio-economic prejudice, alcohol consumption may cause several physiological dysfunctions that very often comprise the impairment of visual functions [ 1 , 10 20 ].…”

“…This deficit is more pronounced with higher dosages of alcohol and depends on the presentation time of the test stimuli 6 , 7 . Acute alcohol intake also significantly changes the processing of contrast sensitivity under certain frequencies compared with control conditions 8 .…”

“…The studies mostly have assessed the effects of alcohol on visual perception using achromatic contrast sensitivity (CS) and acute or moderate alcohol intake (Adams, Brown, & Flom, 1976;Andre et al 1994;CavalcantiGaldino, Mendes, Vieira, Simas, & Santos, 2011;Cavalcanti-Galdino, Silva, Mendes, Santos, & Simas, 2014;Roquelaure, Gargasson, Kupper, Girre, Hispard, & Dally, 1995;Pearson & Timney, 1999;Weschke & Niedeggen, 2012).…”
