When a movie character dons a pair of glasses, you can almost guarantee it'll be accompanied by ill-fitting high-waisted trousers, bad hair and an affinity for Algebra.
But not all chaps wearing thick-rimmed bottle tops are the socially-awkward pointdexters they appear to be. Sometimes the humble spectacle can make a protagonist seem more serious and brooding, or as in Clark Kent's case, aid with an, albeit unconvincing, disguise.
Whatever they're worn for, glasses can transform a character's personality to make them appear funnier, more intellectual and even a little creepy (Patrick Bateman, we're looking at you).
So, here is our salute to the 30 greatest four-eyes on the big screen. Tell us if we've missed any out in the comments below.
