Light amplification visor



The light amplification visor is a powerup that appears as a pair of gray goggles with blinking red lenses. Picking one up will show everything at full brightness for 120 seconds. When 5 seconds remain, the display will begin blinking back to its original light level, signaling the end of the visor's effects. The same effect can also be achieved with the cheat code. Picking up a visor while a previously collected one is still active resets the duration to 120 seconds.

Light amplification visors are the rarest of Doom's powerups, as they undo the various lighting effects that are an integral part of the game's atmosphere. In Doom II, though, three can be found in a single level: the Refueling Base, while in Doom 64 the visor appears just once in the entire game, in the second level, The Terraformer.

They are included in the items percentage displayed at the end of each level.
