As it developed, it became a visual field distortion that was like a combination of the blind spot and the effect of a greasy smudge on a cell phone screen. (The Wikipedia article on "scintillating scotoma" has some animated pictures that do it justice.) It was not what I'd call blurry vision, though, as the rest of the visual field was normal.
Noticing that it was identical bilaterally, I was worried it was a stroke or similar. As a side note, when urgent care tells you,"We're really busy, it may be over an hour", a response of "I am concerned that I may be having symptoms of a stroke", gets you right past the line...
