Study: Those who wear glasses more likely to be intelligent
WASHINGTON (CIRCA) – A new study suggests wearing glasses may be an indicator of higher intelligence, according to The Independent.
The Independent reported Wednesday researchers at the University of Edinburgh conducted an extensive study of how individual hereditary traits may impact cognitive function.
Researchers analyzed data from 300,486 people between the ages of 16 and 102 that had been collected by the UK Biobank and the Charge and Cogent consortia.
The journal Nature Communications first published the study Tuesday, which detailed 148 independent genetic loci associated with cognitive ability.
The loci were used to access whether various attributes – including eyesight, life expectancy and high blood pressure – impacted intelligence.
The study concluded participants who wore glasses were roughly 30 percent more likely to be intelligent.
Higher cognitive function was also tied to several positive health attributes, including longevity, a lower risk of lung cancer and better cardiovascular and mental health.
The study’s leader said she believes her team’s research could prove increasingly valuable in the future.
“This study, the largest genetic study of cognitive function, has identified many genetic differences that contribute to the heritability of thinking skills,” Dr. Gail Davies, the University of Edinburgh’s genetic statistician, said.
“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.”
Lead researcher Ian Deary said research into the relationship between genetics and intelligence has made significant strides in recent years.
“Less than a decade ago we were searching for genes related to intelligence with about 3,000 participants, and we found almost nothing,” he said.
“Now with 100 times that number of participants, and with more than 200 scientists working together, we have discovered almost 150 genetic regions that are relate to how clever people are.”
