The Science of Beer Goggles
The BBC reports that researchers from the University of Manchester have come up with a formula to calculate the effect of beer goggles on vision.
Researchers at Manchester University say while beauty is in the eye of the beer-holder, the amount of alcohol consumed is not the only factor.
Additional factors include the level of light in the pub or club, the drinker's own eyesight and the room's smokiness.
The distance between two people is also a factor.
They all add up to make the aesthetically-challenged more attractive, according to the formula.
The formula can work out a final score, ranging from less than one - where there is no beer goggle effect - to more than 100.
Here is a breakdown of the formula:
An = number of units of alcohol consumed
S = smokiness of the room (graded from 0-10, where 0 clear air; 10 extremely smoky)
L = luminance of 'person of interest' (candelas per square metre; typically 1 pitch black; 150 as seen in normal room lighting)
Vo = Snellen visual acuity (6/6 normal; 6/12 just meets driving standard)
d = distance from 'person of interest' (metres; 0.5 to 3 metres)
There may be some other subtle factors but we still think it is the alcohol that plays the biggest role.
