Hi,
It's kind of like your eyes and the Sun. A quick glance at the Sun won't really cause harm, but if you stare at it you'll fry your retinas. The same principle goes for
night vision and bright light sources. A quick flash from a
flashlight won’t really do anything, but if they keep the beam on you, just move the
night vision device.
As the polarized
sunglass lenses go, in theory, they might help some, but you're still blocking a tremendous amount of the light that can enter the objective, so you will probably be reducing the usable range of the
night vision by a sizeable margin.
