Better than every hour children would have spent in the coal mines

I bet you it's every minute too.

[–] Jackhammer_Joe@lemmy.world 5 points 12 hours ago (1 children)

Scientists even discuss if it might every second as well

[–] jsomae@lemmy.ml 3 points 5 hours ago

Fortunately, milliseconds, no matter the quantity, have no effect.

This is old science.

Increased time outdoors is correlated with a lower risk of myopia. It's no surprise that more screen time = less time spent outdoors

Using screen outdoors = equilibrium

Science!

Or to be less alarmist and 'but everything after I was a kid is bad'

Putting kids in environments where they only ave to focus on things up close ruins distance vision.

I thought it was a myth and that genetics is the most contributing factor ?

[–] pebbles@sh.itjust.works 16 points 2 days ago

I hear genes couldn't have changed as fast as shortsightedness has risen. I've heard bright light like from the sun helps certain systems shape the eyes and as we've rapidly become indoor folks myopia has risen.

I think part of it is sun exposure, my eyesight is much worse than my close relatives, and I was born in Iceland which has much weaker sunlight.

and depending on where they hang out on the internet, figurative myopia too!

But yeah, staring at a close distance for long periods of time tends to lead to nearsightedness in general. However, I've got myopia but not as bad as my siblings who spent less time in front of the screen growing up. Genetics plays a role too, among other factors.

Grew up on computers, can confirm, decades later vision is a fuck.

[–] superglue@lemmy.dbzer0.com 5 points 17 hours ago

Also grew up spending a lot of time in front of screens, vision is 20/15

Not just computers...

As a septuagenarian, started very early as a voracious reader. Usually in bed before sleep. Often by flashlight.

Needed correction for nearsightedness by age 10.

Saw a study recently that attributed significant amounts of reading as a possible/likely cause... Tend to believe. This study seems to come to same/similar conclusion. Also tend to believe.

Can never be certain, but... 🤷‍♂️ 🤷‍♂️ 🤔

Same i was reading a lot as a kid and have been on screens a lot since but my vision isn't horrible. Left eye is definitely near sighted. But overall it's ok. I definitely try to spend less time on my phone wich seems to be the worst for me.

[–] rottingleaf@lemmy.world 5 points 2 days ago

I love such headlines, as if every minute or every cycle don't.

Admittedly my eyesight is in sad shape, but better than my mental state, so.

[–] phillycodehound@lemmy.world 2 points 1 day ago

I also think it's supposed to be Nearsighted not shortsighted. But I'm just a stupid American! LOL

[–] phillycodehound@lemmy.world 2 points 1 day ago

Well my 12 yr old is screwed. He's a gamer and... well spends too much time on the computer. Bah!

Maybe this will be a new point of evolution and our eye shapes will change in a new (not better) way were we see worse... Who knows.... I don't know what I'm talking about . ✌️

That's not really how evolution works, but who knows!
