Quoted from Frax:Jesus, that sucks. I have ocular migraines occasionally that are so bad I literally cannot read text on my monitor. The pain usually, but not always, follows after, but yes...the earlier I catch them the better, like you said.
I get those too. Three or four a year probably, but seems to be more as I get older. Mine last about 30 minutes and never have pain with them. They're usually when I'm driving or looking at the TV or computer screen.
