Hi..
Lately I've been seeing a cluster of semi-transparent crystal shapes, that form a crescent towards the middle right of my vision. Then as time passes, the crescent become larger, moves more to the right, until it passes my peripheral view. I'm seeing a lot of information on migraines, but I don't have headaches with the vision problem. Nothing helps the rainbow crescent shape in going away, it's really strange, I'm wondering what I should do.. and if I'm ok..
