Eli5: What actually causes myopia and does it get better/worse

69 viewsBiologyOther

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?

Myopia is a hardware distortion in the eye. There is some effect that’s a function of the strength of the eye muscles used to adjust the focus of the inter-ocular lens. Myopia caused by the growth of the skull isn’t going to be impacted by screens or anything else.

Presbyopia is certainly going to happen as you age. This will make it harder to read nearby things, such as screens, because the lens will stiffen and get too hard to stretch. This might have a cross-over effect with myopia, but it’s not really a treatment or cure.
