It's official. Wearing glasses doesn't mean you're a nerd but it could be a sign that you're more intelligent, new research shows.

The study, from the University of Melbourne's Centre for Eye Research Australia, shows there are no links between myopia or short-sightedness and introversion or conscientiousness, the socially withdrawn and hardworking personality traits often associated with nerds.

The study's lead author Associate Professor Paul Baird says this research, which has been investigating a number of factors linked to myopia including personality, puts to rest a popular stereotype in the scientific community as well as the general population.

"I was reading a text book a couple of nights ago and it said 'we have to conclude that people who are introverted have an association with myopia' and this was written 10 years ago," says Baird.

"I found it very perplexing that people would go along with this view without having done the study."
