Well that "feeling good" didn't last very long. Pooh. One of those Ocular Migraines found me. The jagged dancing lines... hate those things and I've never seen a cause, even from medical sites. What I know is that I've noticed over the years that often I'd been rubbing my eyes within the past 24 hours, and that applies this time, too... the Canadian wildfire smoke has been affecting my eyes, so I rub even though I know I shouldn't.
What surprised me is that it's come up a number of times here at SF and I was completely surprised at how many of us get these. It's not a literal migraine "headache" for me, but my eyes have an ache during and after.
