Many of us have heard of the so-called “beer goggle” effect. It’s the phenomenon that occurs when someone’s had a few alcoholic drinks and suddenly, all of those people who looked semi-attractive on entering the bar look really, really appealing. Scientists have shown that it’s not just a lowering of standards –
alcohol actually stimulates the part of the brain that judges facial attractiveness.
The formula is:
where:
- An is the number of servings of alcohol
S is the smokiness of the area on a scale of 0 - 10
L is the lighting level of the area, measured in candelas per square meter, in which 150 is normal room lightning
Vo is Snellen visual acuity, in which 6/6 is normal and 6/12 is the lower limit at which someone is able to drive
d is the distance between the observer and the observed, measured in meters
