Congrats on the luck

Then you were likely genetically predetermined to be at least a little myopic, but if you spent less time outside during your developmental phases you would likely be even more nearsighted than you are now.

Same for me, I spent most of my free time as a child playing outside. I grew up in California, weather wasn't a concern, I was outside year-'round. I got my first pair of glasses at age 21. I suspect it's far more genetic than environmental.

You were made for anime, not office work

If we take your eyeballs and take my teeth ("You have the roots of a 6'5" man" inside my 5'4" female body) we have the start of a good build!

Which of us is Doctor Frankenstein though?

Wow I didn't realize that cataract surgery can improve your vision that dramatically. I thought cataracts surgery was something typically reserved for seniors to prevent foggy vision

https://en.wikipedia.org/wiki/Myopia says that both terms exist in English? Not a native speaker; I think I have seen "nearsightedness" more often in English but my first language's term for it translates to "shortsightedness". 🤷‍♂️

"Reduces chances" does not mean "prevents"

You need to read better. It says it reduces occurrence of myopia in a population not that it cures myopia when an individual gets it.

Sure if you have very mild short term myopia caused by eye straining you can get vision back by training your eye. But with kids it’s about how the eye develops when it’s still growing. When kids eyes grow too fast they grow less spherical and that is what causes myopia and that is the kind that you can never cure. Going outside means kids are getting more sunlight in their eye which will slow down the growth and thus their eyes will grow more spherical which means they don’t develop myopia. Playing outside won’t cure myopia but it will reduce the chance of developing it in children.

Yes, I spent 6 months in ICU in 2014, I had a lot of eye issues while I was there not related to my reason for my stay (bilateral lung transplant) but as side effects of procedures and meds but I also basically lost my depth perception unless it was directly in front of me. Living in a 10x10 room for half a year with no far away distances to observe made my eyes weak, it took about six months after I got home to get my full depth prescription back. Indoors just makes your eyes weak, mine is an extreme example, but it doesn’t permanently ruin them.

For some people it is

You might have had a higher degree of myopia if you hadn't spent all that time outdoors.

If this is just a correlation this would have to be a correlation at the population level. Countries where kids start school later on (e.g. 7 years old) have significantly lower rates of myopia than countries that start school early on in a child's development (e.g. 3 years old). It's still possible that this is a correlation, but the correlation would have to be capturing something deeper than just an individual kids screen time. Granted, this correlation would still need to account for differences between individual kids, but it would also need to account for differences between kids at a population level. It's hard to see what could be causing this correlation though. So maybe there's something there we're just not seeing, but at a certain point though the idea that there is a causal relationship starts to seem like the most plausible explanation for explaining this data

It wasn't mentioned in this article, but I remember reading somewhere that it might be because exposure to sunlight affects vitamin D production, which affects the length/shape of our eyeballs as we're growing up.
