What we know about night vision may be related to the sci-fi films of old in which spies and law enforcement officers would use goggles to look for enemies in the dark. In real life, the night vision innovation is used to create more effective safety digital cameras (CCTV) that can check the darkness in your home or backyard.
Each person is imbued with a particular level of night vision skill. Have you observed how your eyes adjust to the dark after a few minutes? A person who trained his night vision well can adjust more rapidly to dark environments. The vision might not be as clear as that of a mechanical device, but with enough training, any person can improve his night vision enough in order that he can see in the dark without trouble.
