'Beer goggles' effect explained
Scientists believe they have worked out a formula to calculate how "beer goggles" affect a drinker's vision.
The drink-fuelled phenomenon is said to transform supposedly "ugly" people into beauties - until the morning after.
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.
KEY TO FORMULA
Beer goggles equation
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)
