Today I was laid low by a visual migraine. If you have never had one of these, it feels like what I imagine a stroke feels like. Severe headache. Brilliant, beautiful, fractured light pattern somewhere in the field of vision. Information coming in from eyes doesn’t quite make it to the cognitive centers of the brain. Short-term visual memory goes kaput. I couldn’t process what I was reading, and couldn’t see the mouse cursor on my monitor.
My first visual migraine scared the hell out of me. I didn’t know what it was and thought I had just suffered some form of brain damage. After an hour or so in a dark, quiet room, it went away. This time, it turned into a full-blown migraine which I currently have in check with massive amounts of powerful medication.
Maybe I should make a Flash demo of a visual migraine… when this one ends.
