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 (although in Doom II, three can be found in a single level: the Refueling Base. And in Doom 64 visors appear just one time in the game, on the second level).

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