Floaters

So yesterday I began having a weird vision thing going on. I was happily knitting a baby blanket for a friend when I saw a pencil eraser sized orange stain on my blanket. Panicked I looked more closely at it and it was gone! This orange spot has come back every few minutes, sometimes several times a minute for 2 days now. I thought it was eye strain but the eye doctor I talked to said that eye strain doesn't cause colored spots, especially in the same eye.
I've never needed them but maybe I need glasses now although I'll go with contacts myself. I've been having horrible migraines for 5 weeks now, even Tylenol #3's don't work! So, maybe it's my eyes. Keep me in your thoughts.
