Since the light has been refracted, or bent as it has been directed through the lenses, by the time the viewer sees the image it is back to front, and upside-down. Monocular are simple telescopes which are only half of a pair of binoculars.
Nitrogen-filled binoculars resist water, rain, and moisture. You buy the telescope and go home, put it up and go to look at the Moon. Many binocular lens cloths are available today, and generally they are meant for one-time use.
In addition to this, the surface of the prism has a special mirror coating to prevent light loss. A simple coating was devised to prevent this, by allowing more light to pass through the lens, and less to be reflected back.
Magnification over ten generally causes the binoculars to lose some image crispness. The higher end models also tend to use technology that improves stabilization and increases view quality. If your application is bird watching, theater or sporting events, a low powered binocular will suffice in most cases.
Binoculars are a key piece of equipment outdoors. Keeping your binoculars from breaking is the best strategy to long and satisfying use of your binoculars.
