Alcohol myopia is a cognitive-physiological theory on alcohol abuse in which many of alcohol's social and stress-reducing effects, which may underlie its addictive capacity, are explained as a consequence of alcohol's narrowing of perceptual and cognitive functioning.
It has three central traits:
Drunken Excess: the tendency for those who drink to behave more excessively.
Self-Inflation: the tendency to inflate self-evaluations.
Drunken Relief: the tendency for people who drink to worry less and pay less attention to their worries.
