Optometrists believe that the reason for this is that we’re tending to be inside more than we used to be, rather than going outside as much, so our eyes basically aren’t getting as much exercise in looking at stuff far away.
I’ve also heard the theory that eyes need ultraviolet light to grow properly, which is missing in artificial lighting.

You mean to tell me, that in this day and age, with half a zillion cars out on the road damn near every day, that people don’t go outside as much as they used to? Let alone have to look half a mile down the road to find the exit sign on the highway?..
Myopia develops in children. If you have any, you’ll know they don’t generally look out of car windows.
Oh, I’ve got myopia, like -5 vision, and yes I was born with it. That’s why I ain’t buying that whole ‘we don’t go outside as much’ theory for even a second.
Edit: Thank goodness for glasses/contact lenses.
I’ve spent most of my life in front of a screen and have perfect vision, a couple of people don’t make a statistic
I grew up on a 40 acre horse ranch and had to walk about a quarter mile to even catch the school bus, yet couldn’t see a pile of horse shit until I accidentally stepped in it.
So still, I ain’t buying that whole ‘spending more time indoors causes myopia’ thing, I was literally born with it.
There are infants born with heart issues, does that mean that you should eat 10 hamburgers a day anyway?
Did everyone miss my point? I didn’t grow up stuck inside so often, I spent a LOT of time outdoors. Hell, the first book I ever read was a survival manual.
I even learned to drive a stick shift at age 7, before I even got glasses. So I still stand by the opinion that indoor vs outdoor environment makes fuckall nothing to do with nearsightedness.
You’re either born with it or you aren’t. It’s all about the shape of the eye.
I spent more time outdoors than indoors.
Gotta say, I didn’t see this coming
I was rocking myopia before it was cool and now that it is Im doing two different versions of it.

Interesting that Chinese optometrists don’t use characters for these tests. With Chinese characters it’d probably be too unreliable I guess.
I don’t think that strategy for testing is purely a Chinese thing. When my kids were little and before they could read, they did eye tests with those same characters. And I’m in America.

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.
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.
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.
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.
