1st generation night vision is presently the most popular type of night vision in the world, due to its low cost. Generation 1 night vision amplifies the existing light several thousand times, allowing you to see clearly in the dark. 1st Generation night vision units provide a bright and sharp image at a low cost, which is perfect, whether you are boating, observing wildlife, or providing security for your home.
Generation 1 night vision tubes frequently produce an image that is
slightly blurry around the edges. This is known as "Geometric
Distortion." When you turn 1st
Generation night vision tube off, it may glow green for a short
time. For this reason, an on/off light indicator is especially useful
and prevents the unit from being left on accidentally resulting in
decreased tube life. These are inherent characteristics of a 1st generation
night vision and are normal.
