Researchers at Roehampton University claim to have found that the beer goggles effect all comes down to symmetry, where one side mirrors the other, or people's perception of symmetry after a couple of hours in a bar. 
In other words, alcohol dulls the drinker's ability to recognize cockeyed, asymmetrical faces. "Alcohol affects our innate human ability to choose a mate. We tend to prefer faces that are symmetrical," team leader Lewis Halsey said. For their research, the team designed an experiment involving images of faces that were tinkered with to make them perfectly symmetrical or subtly asymmetrical. Twenty images of a pair of faces were shown to 64 students. The findings revealed that sober students had a greater preference for symmetrical faces.
