^That. When I switch between my glasses and contacts I get a similar feeling and it can take up to an hour to go away fully, so if you're not wearing them for longer periods that may just be your eyes adjusting to the correction. If, however, the feeling doesn't go away even after an hour or more, I'd go back to the glasses place and have them check the prescription and measurements.
Definitely agree! Years ago the doctors gave me a prescription for astigmatism. I don't actually have astigmatism. =P My glasses literally made me want to throw up, so I couldn't wear them. I tried to tell my eye doctor about it and she basically just told me to "get over it." (She was a real bitch.)
I still remember wearing them after my eye injury, sitting at the station and looking at the computer screen working, and suddenly had to yank them off my face because vomit was rising in my throat. My mom convinced me to go to the glasses place and ask them about it, thinking maybe they just needed to be adjusted. Oddly the doctor "couldn't find" my glasses prescription, so the glasses place measured the glasses to figure out what the prescription likely was. And they were like "These are for somebody with astigmatism. Do you have astigmatism..?"
We had a different doctor give me an exam and write me a new prescription and NOPE, NO ASTIGMATISM. The glasses people were real nice and were like "Yeah, um, if you're wearing glasses for astigmatism and you don't have astigmatism, you're probably GOING to feel dizzy and want to throw up. You can't wear these." So I got a new prescription and it was WAY different.
Just be honest with yourself about if it's an annoying dizzy feeling, which is normal, or if it's really severe and doesn't go away, which is not normal. And if it doesn't go away, definitely go ask about it!!
