Study: People Who Wear Glasses Are Really More Intelligent
A recent study, which is considered to be the largest of its kind, suggests that a certain link exists between people who wear glasses (or contacts) and cognitive function. According to its findings, intelligent people are almost 30% more likely to wear glasses.
For the study, a team of scientists analyzed the genetic information of over 300,000 individuals from existing genomic databases where the participants provided samples for DNA analysis, answered questionnaires, and underwent tests designed to give a measure of their general cognitive ability.
Genetic statistician Gail Davis, a lead author of the study, of the University of Edinburgh in the UK, says: “This study, the largest genetic study of cognitive function, has identified many genetic differences that contribute to the heritability of thinking skills. The discovery of shared genetic effects on health outcomes and brain structure provides a foundation for exploring the mechanisms by which these differences influence thinking skills throughout a lifetime.”
