As far as I know, we still can't make transparent objects out of this stuff. So, as we do in games like Halo when the enemy has body armor that you can't get through, go for faceplates.
I was wondering if it would be possible/effective to make a latticework of CNTs in the lenses of some eye protection to increase their overall protective ability. It seems like they're thin enough where they wouldn't interfere with vision, but would they still retain their effectiveness?
