Can you elaborate on “no way back”?

Not OP, but when I got glasses as an adult and while they really improved the sharpness of my vision I could feel my unassisted vision getting worse, so I stopped using them and get by with slightly unfocused but unassisted vision. I assume if I wore them full time my unassisted vision would degrade to the point where I then need the glasses full time.

I've got half a diopter (ish) of astigmatism in my right eye and it can be slightly annoying but interesting to know that using glasses would risk making it worse.

The weird thing is it seems to get noticeably worse or better depending on how much time I spend outside

Your assumption was false.[1]

I got glasses 2 years ago for a very minor prescription. Your eyesight sucked before you’ve just forgotten how badly. I had an eye test very recently for Contacts and my prescription is the same 2 years later

I meant that once you decide to wear prescription optics you can’t go back to not wearing them, of course excluding eye surgery. In my case I could stick to good enough vision and luckily 20 years later Im still not wearing glasses. My main point was that I was getting eye strain from blue light and once I reduced it the problem dissapeared.

This isn’t true? Myopia develops rapidly in youth then stabilizes in adulthood. It gets a worse with age, not corrective lenses. Then sometime after 40 you flip to presbyopia when your lenses lose flexibility.

I don't have severe myopia and I'm fine with no glasses for now. The optometrist detected .5 correction needed but advised me to not go for it for the reason I mentioned. I think they are more qualified to give this advice than some rando on the internet. If they were a mercenary they'd tell me to go for it, that optometry practice was part of an eye glasses store and I'm sure they'd gain from my business there. And here I am 20 years later not wearing glasses yet. As I'm getting older my vision is getting slightly worse, I'll probably get to wear them at some point but that's beside the point.

There is plenty of information about this in trusted sources, the way you're describing this is incorrect. Overcorrection and badly designed simplistic optics can make myopia worse in childhood when the eye is growing. Your eye is no longer growing.

Don't trust everything your doctor says verbatim, they often oversimplify and their information can be out of date. Give your doctor the benefit of the doubt but check it against other sources and use it to build a mental model.
