Light amplification visor
From DoomWiki.org
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 idbeholdl. 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.

Notes[edit]
Light amplification visors originally used colormap 33 in the press release beta to simulate night vision goggles. However, this tended to make the game darker and sprites more difficult to discern due to the limited number of shades available in the palette, which probably explains why it was changed.
In the Atari Jaguar port and most other ports directly based on it, the visor is absent, along with the blur sphere. The item was restored for the Sony PlayStation version, and appears particularly in maps derived from Doom II. In Doom 64, instead of blinking, the added light effect simply fades into the current lighting when the power-up runs out.
Many players have lamented the replacement of the light amplification visor in Doom 3 with the flashlight, as the player cannot use the flashlight and another weapon at the same time. This was a deliberate limitation implemented by the developers in an effort to increase the tension and possibility of scares, as the player would have to make a choice between whether to brave dark areas with a weapon and low visibility, or improved visibility via a flashlight but without adequate firepower. Still, the complaints prompted id Software to address this in Doom 3: BFG Edition by changing the flashlight into an armor-mounted device.
