Question by Deviously Devious: How can you see more clearer in night vision binoculars at night?
I bought a night vision binocular (20X50). It is one of those ordinary binoculars that doesn't require batteries. I tested it out last night, and it quite didn't rise to my expectations. So how can I improve my night vision and the binoculars?

It sounds like to need to know what to expect from them more than anything else. The major difference between a set of night binoculars and regular binoculars is lens size. For your set, this is the 50 in 20X50. This is the lens diameter in millimeters. The larger the lens diameter the more light they collect. For night use, 50 is on the small end of the range. 60 or 70 mm lens would do a better job.
The 20 in 20X50 is the magnification power of the binoculars. 20 is much too high a power to be held by hand. It would be very difficult to hold them steady enough to see well. The image will bounce and jiggle around from small movements of your hand, arms, and body. Even your heartbeat and breathing would cause some problems. You will need to rest them on something or get a tripod. 10 power is about the highest you can go for handheld binoculars.
