Light amplification visor



The light amplification visor is a powerup first introduced in the Knee-Deep in the Dead episode of Doom. 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.

The powerup appears as a pair of light gray goggles with blinking red lenses in Doom and Doom II, whereas in Doom 64 it is a yellowish gray and the blinking lights alternate between purple and violet. 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.

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