Hi Jemsalva, I’m not exactly sure what this means but have a couple of thoughts. If it is with your glasses on, it could be because of a correction for astigmatism. You’ll want to reach out to your prescribing doctor to help figure that out. It is not vertigo (with vertigo, it seems like the room is moving, although you are still). If it is a correction for astigmatism (either correctly or incorrectly put in your glasses, you can absolutely have symptoms of nausea, etc. 🙂
