People with blue eyes might study more effectively and perform better in exams, new research claims.
Tests by scientists in the US showed blue-eyed people were better strategic thinkers than those with brown eyes.
People with brown eyes outperform those with lighter eyes in reaction time trials making them more likely to succeed at rugby, hockey and golf, the researchers at the university of Louisville found. This might have surprised Einstein who had brown eyes and was not known for his sporting prowess.
Professor Joanna Rowe, who did the tests, said there was no scientific answer to why the contrast in people with different eye colour might have occurred.
But Dr Tony Fallone, senior psychology lecturer at the University of Bedfordshire, who has studied eye colour genetics, said it should be taken more seriously as an indicator of traits.
Blue-eyed academic successes include Stephen Hawking and Marie Curie who twice won the Nobel prizes, for Physics and Chemistry.
