The purpose of this paper was to characterize the contrast sensitivity function (CSF) for spatial frequencies equal to 0.25, 1.0 and 4.0 cpd (cycles per degree) in the absence (Control Group-CG) and after moderate alcohol ingestion (Experimental Group-EG). For such, the forced choice psychophysical method was used. The participants were four 21 to 30 year-old-women with normal or corrected visual acuity. The results showed a significant difference between groups at the spatial frequency of 4.0 cpd (p= 0.039), such that the EG was more sensitive to contrast than the CG. These results suggest alcohol-related alterations in the CSF.
