I have had what I am fairly certain is HPPD for 2 years now.
I have not seen a doctor to prove it, but chances are they couldn't accurately diagnose something like that anyway.
It's basically like an extremely mild visual trip constantly.
At first it was somewhat difficult, but once I got used to it I loved seeing beautiful fractals everywhere I looked.
It did not effect my actual vision, as recent eye tests have proven my vision is still 20/20.
As for what caused it; it happened after taking some bitter tabs that I'm not so sure was really acid.
There was a 2h come-up period and effects lasting longer than 12h. Effects seemed like a "dirty" acid if that makes sense?
I have had real acid before as well so I can compare.
Phenethylamines and LSD make it a lot worse in my case, Tryptamines not so much.
Tryptamines do effect it, but in a more positive way, I like my vision changes after taking tryptamines!
Cannabis also makes it quite a bit worse in my experience.
On top of that, I get significant visual effects with lower doses of psychedelics than in the past. Of course psychedelics aren't only about the visuals but it's still pretty convenient!
I haven't really had a break from psychs lasting longer than a few months so no clue how long it's going to take to remove the HPPD. I suspect it would take a year or more, but I don't know.

I've been thinking something similar too, objects look less solid and more energetic, vibrating slowly.
Fractals in nature stand out like never before, maybe there's something to this!
I know I rather enjoy my visual changes.
