* Capitol citizens: They have access to the latest technology and luxury items, so it's plausible some Capitol citizens might have possessed night vision goggles for recreational activities or other purposes.
* The Gamemakers: They control the arena and the Games, so it's likely they had access to advanced weaponry and technology, including night vision goggles, to monitor the tributes and manage the game.
* Tributes: It's highly unlikely that tributes would be equipped with night vision goggles as they are not essential for survival in the initial phases of the Games. They are more beneficial for navigating the arena at night or for hunting, which may not be the primary strategy for all tributes.
While the exact number of night vision goggles isn't specified, it's safe to assume they weren't abundant and were likely restricted to a small group of people, including the Capitol citizens, the Gamemakers, and potentially some strategically placed tributes.
