Night Vision is the ability to see in the dark. To accomplish this, night vision devices are used, including night vision goggles and scopes. Such devices use an image intensifier, which increases the intensity of light, enabling people to see in low-light conditions.
Night Vision Goggles is a piece of equipment featured in Battlefield 2: Special Forces. It allows players to see in a dark environment. They can be activated by pressing on the keyboard. While using Night Vision, the player's HUD will be lit with a green tint. Activating night vision does remove some of your peripheral vision, and, should the user be exposed to a flashbang blast, the blinding effect will be amplified by the goggles. The goggles also have a limited battery life, which can be recharged by turning them off for a while. They can be useful on dark maps such as Leviathan and Night Flight, but are unusable on day or well-lit maps like Warlord and Iron Gator.
While Night Vision is not in anyway usable to the player in Battlefield 3, it is used at the end of the mission Going Hunting when Shark 4-6 lands their F/A-18 back at the aircraft carrier from the start of the mission.
