Abstract
A vehicle night vision system comprising a headgear mounted night vision goggle 11 incorporating an image intensifier which produces an intensified image of a scene forward of the goggle superimposed on a user's direct view of the scene through the goggle wherein the intensity of the image produced by the intensifier is reduced when the user views a vehicle interior display via the goggle to prevent interference with the user's direct view of the display through the goggle.
