Fallout 3
Meshes and and an inventory icon for Night-Vision Goggles appear in Fallout 3's resource files but are unused. The goggles were meant to go along with the Merc Veteran Outfit and have different models for male and female heads.

The Peepers are another pair of night-vision goggles which were cut from Operation: Anchorage

Fallout: New Vegas
Fallout 3's graphical assets for the night vision goggles do not remain in New Vegas's art files (except the inventory icon). However, the model folder contains .egm files (used in Gamebryo engine games to modify equipment placement, i.e., on male and female-shaped heads) which were not present in Fallout 3's data. Some night vision functionality can be seen in the Varmint rifle night scope and Dead Money's Ghost sight.
