Abstract : This study examined the effect of alcohol on contrast sensitivity at normal levels of illumination. Contrast sensitivity was measured, using the Vistech VCTS 6500 Test Charts, on two groups - an alcohol group with peak Blood Alcohol Concentration (BAC) levels of 0.12% and a placebo group. Both groups were assessed prior to ingestion of alcohol, at the peak BAC of the alcohol group and at five one hour intervals following peak BAC. There were no differences in contrast sensitivity between the two groups at peak BAC. The results were in keeping with previous research that suggests that alcohol does not affect initial sensory processing.
