According to a new study, which the journal Nature Communications recently published, the biggest cliché in the world according to which people who wear glasses are smarter might actually be true. Intelligent people have spent centuries struggling to read as many books as possible in dusty and darkness-filled libraries. This took its toll on their sight. Now, science claims that glasses wearers are indeed the more intelligent ones. In order to come up with this result, a team of researchers from the University of Edinburgh analyzed genetic data coming from over 44,480 people.
Their results said that more intelligent people were about 30% more likely to require reading glasses than those had lower scores. Moreover, this recent study also connected a higher cognitive ability with a better overall cardiovascular health, thanks to some important genes. This was, in fact, the most complex and advanced research on intelligence genes to date. For it, the team examined 148 genomic regions that are related to a higher intelligence level. Moreover, 58 of them have never been analyzed or reported. According to the team, their results could shed some light on the reason why people’s cognitive function declines with old age and illness.
If you wear glasses, you might be more intelligent than others
It’s worth noting that the nature of the study did not allow the team to establish a genetic link between poor eyesight, intelligence and cardiovascular health. Dr. Gail Davies, the leader of the study, says that their efforts haven unveiled many genetic differences that led to the heritability of thinking skills.
These shared genetic effects that have a clear influence on health outcomes and brain structure could provide the base needed for studying certain mechanisms. Through these mechanisms, these differences influence our thinking skills while we are alive. It’s important to note that none of the people who were examined had a stroke or dementia.
