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
You won’t see evolutionary changes in only 2 generations. That’s not how evolution works. Also you’re assuming because more humans are born with x thing, it’s an evolutionary change. Again that’s not how evolution works.
Did you read the paper from my 2nd link? There seems to be a growing body of evidence that suggests that is indeed possible:
Similar to the increase in the prevalence of persistent median arteries of the forearms, the prevalence of other anatomical features such as spina bifida occulta (Henneberg & Henneberg 1999; Solomon et al., 2009; Lee et al., 2010), tarsal coalitions (Solomon et al., 2003) and fabella (Berthaume et al., 2019) has increased over the last 2–3 centuries. Evidence indicates that changes in the natural selection pressures acting on these specific anatomical features could have caused microevolutionary processes, leading to the observed increases in prevalence rates (Henneberg and Henneberg 1999; Solomon et al., 2009; Lee et al., 2010; Rühli and Henneberg, 2013; Berthaume et al., 2019).
Obviously actual research would have to be done to confirm or deny it in this case, and I probably should have stated my original thought a bit more skeptically.
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.

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.
I think it’s honestly smartphones and screens in general. Our eyes weren’t meant to be looking at tiny glowing screens all day
