Are you happy with your eye colour? Have you ever found yourself wanting blue eyes instead of brown or wishing for a stronger hint of green? This new research is likely to influence how you feel about your peepers a little bit more.
Research conducted by the scientists at the University of Pittsburgh as concluded there's a link between the colour of our eyes and our health.
The study suggests it can impact our ability to multi-task, alcohol tolerance and the risk of diabetes.
One of the most staggering results from the experiment was the relationship between eye colour and pain threshold.
Scientists' findings suggest Caucasian women with light-coloured blue or green eyes can tolerate pain and better than those with darker brown or hazel eyes.
At a meeting with the American Pain Society, Professor of anaesthesiology Inna Belfer explained in a study of 58 pregnant women, those with lighter eyes even experienced less pain and anxiety during birth.
Dr Jari Louhelainen, a senior lecturer at Liverpool John Moores University, spoke about this theory to the Daily Mail.
'What we know now is that eye colour is based on 12 to 13 individual variations in people's genes," he said. "These genes do other things in the body. One of them, NCX-4, which is linked to darker eyes, controls many proteins, of which one has recently been linked to pain."
Those with dark eyes aren't only susceptible to feeling discomfort, though. The Mail reports a survey on over 12,000 men and women carried out by Georgia State University, Atlanta discovered people with light eyes drank less alcohol than those with dark.
"The reason brown-eyed people may drink less - and also be less likely to be alcoholics - is because they need less alcohol to become intoxicated," says the newspaper.
So the next time you find yourself feeling a bit tipsy? Blame it on your eye colour.
