It is quite easy to see everything during the day... But at night, we can see very little . Night Vision device lets us see again

Night Vision Approaches ,[object Object],[object Object]

[object Object], Sufficient intensity range is simply the ability to see with very small quantities of light. Although the human visual system can, in theory, detect single photons under ideal conditions, the neurological noise filters limit sensitivity to a few tens of photons even in ideal conditions. Many animals have better night vision than humans do, Enhanced intensity range is achieved via technological means through the use of an image intensifier, or other very low-noise and high-sensitivity array of photo detectors.

[object Object],The image is green because the phosphor is green in colour that is good for human eye to pick up detail
