They say that your eyes are the window to your soul, but new research has found that the colour of your eyes might actually be the window to your health. So how is that possible?
A number of studies have found that the colour of our eyes affect how we feel pain, how well we can hold our drink and even our skill level when it comes to sport and hobbies.
Carried out at Pittsburgh University, the study found that women with lighter coloured eyes experienced less pain during childbirth compared to those with darker eyes, while the women with lighter eyes were also able to tolerate more alcohol. But don't run to buy contact lenses, these differences boil down to one thing: your genes.
A senior lecturer in biomolecular sciences at Liverpool John Moores University has explained that eye colour is based on 12 to 13 individual variations in genes, and these genes also affect other parts of the body.
Take melanin, for example. This chemical not only makes eyes darker but also makes people more susceptible to alcohol. Not to worry though, according to scientists people with darker eyes also have increased reaction time, so they're generally better at fast-moving sports.
And people with lighter eyes? Well the University of Louisville found that the slower reaction times in lighter eyed people helped with activities that require more planning, so although you have no excuse next time you study, you also have a wonderful reason to get down the golf club when you're in need of some physical activity!
