Influence of Socially Used Drugs on Vision and Vision Performance.
Abstract
Four experiments on single and mixed drug effects on vision function are reported here. The experiments were conducted double blind with placebo controls. The results, in general, do not support an additive model of action of alcohol and marijuana on vision function or other drug affected physiological and psychological variables. Dynamic visual acuity (DVA) is reduced for high and low contrast targets by alcohol and marijuana, and by drugs in combination. The proportion of red and green which must be mixed to match a standard yellow is significantly altered by alcohol, marijuana, and these drugs taken together. Alcohol significantly increases foveal glare recovery time, and marijuana also retards this recovery time. Visual search times are significantly reduced by alcohol and by alcohol and marijuana when taken together.
