Go see your Opthalmology (EYE) doctorr and do not put it off. ANY time you see things in your vision or have visual changes with movement, you need to be seen...SOON. IF it happens to be your retina tearing or detaching it's an emergency. NOT meant to scare you, just fact. ONLY the eye MD can tell you by looking IN your eye with special machines.
It is time to see a doctor. It sounds to me like it MIGHT be silent migraines. My opinion means nothing, Please see a doctor.
