The eyes are the window to your soul? Maybe, but new research is highlighting how the colour of your eyes could hold clues to your health.

The curious links between eye colour and health have fascinated scientists for years, leading to a body of research that suggests the colour affects how much you feel pain, your chance of getting diabetes, how quick your mind is - and even how well you can throw a Frisbee or handle your drink.  The latest piece of evidence in this scientific jigsaw has been added by scientists at the University of Pittsburgh. They found Caucasian women with light-coloured eyes - blue or green - appear to tolerate pain and distress better than those with brown or hazel eyes. Inna Belfer, a professor of anaesthesiology at Pittsburgh University, says the study of 58 pregnant wome.  In found those with light-coloured eyes seemed to experience less pain while giving birth.  Furthermore, the women with lighter eyes suffered less anxiety after the birth, lower rates of depression and fewer negative thoughts, Professor Belfer told the annual scientific meeting of the American Pain Society.
