Karen has always had a squiffy eye and doctors have told her that she can have surgery to have it corrected if she wants but she's never wanted to have it done and never will. She likes the fact that people find it off-putting and when talking to her just don't know which way to look. Karen also has a knack to roll her bad eye into the back of her head to really hit it home.
Through the years people have called her many names due to her affliction but one that has stuck because Karen liked it herself was 'Ambly'. Karen also has a skill which is a direct cause of her wonky eye: she can tell if anything is squiffy even by the slightest degree with just a quick glance. Due to this many business sectors hold Karen in great demand for her unusual abilities. From the scientists at CERN to the builders of the worlds largest skyscrapers, to Tony from down Karen's local pub who always asks her to see if he's squiffy but Karen is always to polite to give him an answer. In all fairness everyone at the pub already knows the answer to that one...
