Cheep sunglasses.  (Seriously) (-:

It's what we used to get our QuickCams running on our outdoor mobile robot
back in '97... the other teams at competition got a good laugh until they
saw how well it worked.

The QuickCams are really sensitive to IR because of their CCDs... so the
sunglasses might also work for you... or they might block out too much...
so get a cheap pair and try it out. (-:
