Has anyone else taken omeprazole long term?

I’ve taken it daily for almost 4 years for acid reflux problems, and in the last month I’ve noticed that every night my right pupil gets massive and my left pupil stays normal. It makes it hard to drive at night. My right pupil, because it’s so big, makes light blurry and causes astigmatism with street lights and car lights. Whereas my left eye sees just fine. Is this normal? Should I get my eyes checked? I’ve never had issues with my eyesight before and I don’t take any other medications.
