It’s almost a
guarantee that at some point in your life, you watched a TV show where a
character who’s supposed to be smart – or, more specifically, who’s supposed to
be a nerd – was seen wearing thick glasses. Glasses have been a visual
shorthand for intelligence for generations, but as it turns out, there may be a
relation between intelligence and poor vision.
According to a
large study of over 300,000 people, people with higher cognitive function are
28 percent more likely to need corrective lenses, and 32 percent likelier to be
shortsighted. These people were also more likely to live longer, with fewer
health problems like heart attacks, high blood pressure, and lung cancer.
relationship between intelligence and vision, as well as the other health
issues, is due to a genetic overlap between them.
That said, while
there is a correlation between intelligence and poor vision, scientists have
not determined any cause to link the two. Further, this study almost
exclusively included subjects of European descent, and that information could
not be extrapolated to people of other ethnicities.
It’s also worth
noting the psychological link between glasses, intelligence, and physicality.
People who wear glasses are more often perceived as smarter, less threatening, and
more honest than people who don’t wear glasses.
