I wonder if you could find some polarized clear lenses for a pair of
glasses. Should have the same effect as the sunglasses without the shading.
You might could even rig something with eyeglass frames and some polarizing
photographic filters. It might look funny but hey, you're already slogging
through the creek at night wearing waders with a flashlight on your head....
