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?

Hello.
Not a professional but here’s how I remember it (I am myopic):
Imagine your eye is like a ball. The ball has a small hole. Light from your surroundings is supposed to enter the inside of the ball through this hole. Ideally, this light is supposed to fall on the inner surface of the ball for you to be able to see clearly.
But due to some medical reason (eye ball shape or muscle of the eye, e.g), the light falls in front of the inner surface of the eye. Making the surrounding object not clear.
Now imagine keeping that object in its place but you move the ball closer to the object. As you do, the light would now move closer and closer to the inner surface of the ball and eventually land on the ball. This moving the ball closer to the light source means you are coming closer to the object and can see the object if it is closer to your eye.
Hence when you are myopic (near sighted), you can see objects closer to you but not far away. The glasses / lenses correct this behaviour.
Your myopia can get worse. I don’t know if it can get better, LASIK means that the answer to that is probably a yes.
Mine has more or less stabilized.
Hope that helped!
