Get my vision back to normal.

Almost all of that is myth and rooted in quite out of date science. I don't remember where I read it so unfortunately no source, but doctors used to undercorrect when giving glasses to people whose eyes were still developing because of the same school of thought. Eventually studies were done on children who were given the correct prescription, and it was found that the children who were given weaker glasses than they needed ended up going on to develop worse vision than the ones who were given correct glasses- eye strain worsens eyesight.

>Is there any way to fix this on a long period of time? I know its probably caused by me being a shut in and looking at screens all day long and not a genetic defect.
You cannot fix it, ever, short of surgery. You can help prevent it getting worse but it is almost certainly in part genetic. Go to an eye doctor and get an accurate prescription for glasses, find a pair you like and feel confident in, wear them regularly, and don't squint or otherwise strain your eyes.

Thanks for the descriptive answer.

However, I don't think it's related to my genes. My parents don't have any history of myopia, but my mom does have astigmatism. As I said before, it's probably because of the fact that I spend so much time in my room, looking closely at things (screens, books). There really is no way of trying to correct this while I'm growing? Eye exercises?

No. Evolution is imperfect and eyes arent muscles that get stronger and better. They just wear down or start fucked in the first place.

You wont improve.

But ill add, it could even be astigmatism (less scary than it sounds).
One or both of your eyes is ovular shaped instead of spherical..

Its extremely common, but will cause ever so slightly blurred vision, eye strain and eventually, headaches and more vision wear.

You're right, it could be astigmatism.
Is it true that the lack of natural light can lead to astigmatism in the long term? I've read about it a few times. I spend all day inside, so if it's true, it's likely a cause.

Other than that I plan to see an optometrist this summer, as soon as school ends.

In the meanwhile, what's the best way to keep my vision from worsening?

I dont know enough because im not an optometrist but im pretty sure astigmatism is just the way your eyes formed flat out.

Dont quote me on that part. Take it to google.
