During the Vietnam War, Gunners Were Given Glasses That Allegedly Exposed Another Dimension

During the Vietnam War, U.S. helicopter gunners were reportedly issued experimental red tinted night vision glasses known as Dicyanin glasses. Far from just enhancing vision in the dark, these devices allegedly allowed soldiers to see into another dimension filled with terrifying creatures invisible to the naked eye. Some accounts claim the gunners began firing wildly at unseen monsters only they could see.

The idea echoes the plot of John Carpenter’s They Live, where special glasses reveal hidden beings living among us. A similar case in Russia involved a man who obtained a fragment of alleged UFO glass. When viewed through it, a hovering craft reportedly became visible in the sky but only through the lens.

Filmed on location in Hanoi, this deep dive looks at the strange intersection of military experimentation, altered perception, and the possibility of hidden dimensions.
