Aggghhh, I can't See!

I don't "click" my visor all of the way down and sometimes leave it up a notch. When I find myself in a predicament similar to what you experienced I try to control my breathing but that requires a little pre-planning. If you can't raise your shield you need to recognize when it's likely to happen. Mainly when you're going slow or stopped.

+1, use the same method, but need no glasses for riding.
