Not to be confused with the thermal vision goggles (though they share an identical icon), the night-vision goggles amplifies extremely dim, available light and present it in a green-ish display so the player can see more clearly in dark areas. The night-vision goggles look similar to and share the exact model as the thermal vision goggles. After equipping the goggles, it is possible switch to another weapon while retaining the night-vision goggles' effects and even drive vehicles. They will only become available once the player has finished Breaking the Bank at Caligula's.
If you have the goggles on and play an arcade game, when you exit the arcade game you will still have the goggles on, but the effects will not be on.
