I never had the experience you are describing. The closest I got was when I got a flexiframe that couldn’t be adjusted by hand - because that’s the whole point of those - and the nose bridge was set such that the edges of the lenses were in a different spot than I was used to. This resulted in the world swirling in a dizzying way when I moved my head because my peripheral vision was adjusting to the difference. That process took about a week, I think.
I have also found that it hurts my eyes to try to wear glasses inconsistently. For me I need to wear them all the time, or not at all. So if you are being inconsistent you may be making it difficult for your eyes to get used to focusing differently.
It might be worth talking with your optometrist though, in case something isn’t quite right. (S)he can test the lenses and verify the lenses are right - they could be wrong, and that would be a problem for sure.
I heard that game has a really bad problem with cheaters. Addressing that seems like it would take precedence over getting the game on Steam. You only get one shot to make a first impression and all.
