Experts point out that the overuse of screens and decline in outdoor activity are some of the factors behind the rise of the condition which, if not corrected, increases the risk of blindness
In the study, Professor Henneberg and colleagues aimed to investigate the prevalence of persistent median arteries in postnatal humans over the last 250 years and to test the hypothesis that a secular trend of increase in its prevalence has occurred.
People with worse vision still have a higher chance to die due to poor vision related deaths, (for example not seeing a car coming) than people with perfect eyesight. Not everyone with bad eyesight wears glasses.
I mean, it makes sense. With widespread adoption of vision correction, there’s no longer an evolutionary advantage to having naturally good vision.
Evolution doesn’t work on such short time scales.
Except it does. Microevolutions can absolutely occur on time frames of under a hundred years.

That’s a fun new definition of “secular”
Sure, but they won’t spread to the majority of the population in 100 years.
The median artery of the forearm does for example.
It absolutely can happen on such short time scales. Regardless, it’s also been hundreds of years.
Not in humans. And glasses have been universally available for less than 100 years. Before that they were a luxury item.
