They have a few different flavors.  I'm assuming these are the ones you're using?

I tried Boxwave screen protectors from Amazon, and they DO cut the reflection and glare, but they also produce a pretty good haze effect.  I will try them again with a more fair test, since I was wearing a white shirt that day.  I usually try to wear darker shirts to fly, but it was just a quick test flight. 
NuShield replied to my inquiry, and they're shipping me a pair of their TripleA shields, so those will probably be the next ones to test. 
Thanks,
