This has happened to me for a long time, and I never really thought much about it. But when I go to bed at night, after being in a room that had lights on, I'll see moving rings of light sometimes. Usually I just have to open my eyes for a few seconds and it will stop. If I focus on it I can seem to notice it even more. It doesn't happen every night, but here and there. I've also had it happen in the morning, my room semi-dark. I'll wake up for a second, roll over and close my eyes again. Only to see these moving rings of light and sometimes spots.
Just curious if this is normal? It happens with both eyes, and I've had a normal eye exam this year. I am prone to ocular migraines, is that something related? Thank you!
