In the past century, the prevalence of myopia—science-speak for being able to see only what’s right in front of you—has been on the rise. So much so that it can’t all be blamed on geeky genes¹.

 

To nail down the potential environmental influences, researchers focused on the classroom. They gave eye exams to nearly 5000 German subjects in a project called the Gutenberg Health Study.

 

The researchers found that individuals with 13 years of education were more myopic² than those who didn’t get past primary school. And more than half of those with a university degree could use a set of specs, compared to less than a quarter of the folks who quit after high school or secondary school.

 

All that learning takes a lot of reading. Which itself is associated with nearsightedness. Or the nearsighted may gravitate toward pursuits easier to see—like hitting the books. Either way, seems that being a good student may not require great pupils.

 

Thanks for the minute, for Scientific American's 60-Second Science. I am Karen Hopkin.
