"We have literally busted the myth that people who wear glasses are introverted or have particular personality characteristics," study leader Paul Baird of the University of Melbourne's Centre for Eye Research said in a statement.

"They are more likely to be agreeable and open, rather than closed and introverted."

Utilizing the University of Melbourne's Australian Twin Registry, the study involved 633 twins and a comparative group of 278 family members .

Participants were analyzed using a state-of-the-art measure of the five major personality factors -- openness, conscientiousness, extroversion, agreeableness and neuroticism.

The study, published in Investigative Ophthalmology & Visual Science, found that the comparison of family members and twins showed no link between myopia and introversion; however, there was a significant but small association with myopia and agreeableness.

"This shows that people, particularly children, should not avoid or delay wearing glasses due to preconceived ideas about what it would imply about their personalities," Baird said.
