I have a few questions regarding myopia.
1) Do screens actually cause myopia, if so how, is it how closely it sits from our eyes, if it’s in the darkness or is it the screen itself
2) Can myopia get worse, or does it stop and stabilise at a certain age?
3) Are there ways to reverse/treat myopia?
In: Biology
Myopia is generally thought to be caused by lack of intense lighting falling on the eye during development…in other words, your eyes grow too long as a kid because you don’t spend enough time outdoors in full sun as a small child, and this means your eyes don’t get the “image in focus, stop growing” signal produced by bright light focused on the back of the eye. So your eyes grow too long front to back causing myopia.
Myopia tends to stabilize a bit once you and your eyes stop growing, but can still slowly change after that. It doesn’t really get better.
You can wear glasses or get surgery, that’s about it.
