Early Night Vision "Blackout Eye" (1950)
From a 1950s issue of Popular Mechanics:Searching for persons or objects in total darkness poses no problems for soldiers wearing sniperscopes. Clamped to a helmet, the equipment combines an infrared light source and an electronic telescope. Its energy comes from a power pack and battery which can be carried in a knapsack on the operator's back.
