What range/years are you specifically referring to? It seemingly is as good as ever, and I'm 32 now. I'm guessing that would start being around 40s, when the general eye-sight starts to decline?

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).

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.

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.

Yep, right around your mid-40’s in my experience. Friends have said it started the day they woke up on their 40th birthday.

There’s a new-ish body of research that suggests aging is non-linear/happens in “cliffs,” and that the first big decline is mid-40s. Something to look forward to.

About the time you start needing reading glasses to see your phone or computer screen. Between 40-50 years for most people. You will develop an appreciation for the people who complain about small fonts and low-contrast color schemes. And yes, adapting to darkness takes longer.

I already do this at this point, so guessing that's a club I'm in already, even if my eye-sight is perfect :)

Well, I guess I'll report back in 10-20 years and I can finally have this confirmed for all of us.
