If you want a classic look for your eye wear that’s cool and has fashion staying power, then look no further than the geek frame. An iconic look embraced by everyone from Johnny Depp to Mark Ronson, Lily Allen to Madonna. History, style and fashion, what more could you want?

This look is characterised by chunky, heavy plastic frames in black or tortoiseshell brown, with a shape reminiscent of the old NHS plastic frame. It’s been in fashion for ever, and all eye wear collections feature some version of it. Variations on the theme can be squarer, more rounded, flat or curve topped.

Although high fashion, this type of glasses frame is practical – perfect if you are short sighted as it will cover up thick spectacle lens edges. It is sturdy and strong, and black or brown are always a chic choice for boys and girls alike. Even blondes like Chloe Sevigny have been seen wearing them, hers fade to clear at the lower edge. Katie Holmes, with her dark brunette colouring, favours solid black.

Try to make sure the top rim of the glasses frame sits in line with your brows – choose a curved top rim if your brows are arched, men or girls with straight brows can go for the classic square shape. Zachary Quinto and Josh Hartnett have been seen in shapes that suit their features perfectly.
