I don't think there is a rule for that? At least not in my case. My eyesight got worse really fast out-of-nowhere when I was like, 15 years old? And since then it didn't change anymore. I got myopia, after a few years of too much computer screen (the old CRTs).
While there was a suspicion of eyesight troubles in my late teens, it really kicked in during a period I was working on pretty crappy screens, that was in my late 20's. It's not much but enough to give me headaches when not wearing them.
How old are you? Most people experience worsening eyesight mid 40s.
I'm currently 37, I hope it doesn't start to get worse again anytime soon. I never used glasses regularly, btw. Always had the impression that would weaken my eyes long-term.
