night-vision screen

This hangs in front of your face, letting you see in (almost) complete darkness.  It can be worn separately, or fitted to the peak of a helmet – types (1) and (2) of the Federation hats.

Hais and I wore helmets with night-vision screens at the Temple of Ikutiki.  See Report F.

Tony and I used night-vision screens for our secret visits to Naxi 17.  See Report 19.

Tony wore a helmet with a night-vision screen when he left the ship to look for the mysterious boy on Abzuke 5.  See Report 33.
