14 DAY TRIAL // Surely you saw at some point the commercial in which one man looks at a woman while drinking beer and he starts to think that she looks more and more beautiful as more and more beers are being drunk.
Researchers call this phenomenon beer goggles and describe it as the effect alcohol has on the way people perceive a person of the opposite sex.
So far, it has been believed that beer goggles were the exclusive effect of alcohol on the brain, but optometry professor Nathan Efron, of the Manchester University, comes to infirm this theory by saying that there are many factors which contribute.
"The beer goggles effect isn't solely dependent on how much alcohol a person consumes, there are other influencing factors at play too", he said.
And now, there is even a formula that takes a person's eyesight and the level of smoke in a club into account when estimating the beer goggle effect.
"The formula shows for example, that a person with poor vision who's talking to someone in a very smoky bar will be experiencing a beer goggles effect close to someone who has consumed eight pints in a smoke-free and well-lit room", Nathan Efron explains.
The formula can work out a final score to measure the effect.
According to News.com.au, a score of less than 1 means no change in perception (or as the Australian site puts it, an ugly person remains ugly), a score between 1 and 50 points out a slight change (a completely unattractive person becomes a little bit more attractive).
Things change dramatically after 50. In this way, between 50 and 100, a person you would feel under no circumstances attracted to becomes a potential sexual partner.
There is another score, over 100 (although the author of this article warns about the stability problems which might occur at this score), at which a physically abominable person becomes a god/goddess.
