Raise binoculars to your eyes and you can see everything far away as if it was right in front of you. Any stain or mark on the surface of a binocular lens tends to scatter light, thereby producing low-contrast viewing.
You position your telescope to look at the Moon, you see craters, and find that soon as you go to call someone to take a look, they take a look and it is gone.

Early recorded patents indicate that telescopic monoculars were made in seventeeth century.
They can withstand complete immersion in water and remain dry on the inside. The objective lenses are located on the end of the binoculars furthest away from your eye when viewing. When you're trying to spot game that blends in with its surroundings, you need every edge you can get.
A field-of-view of 390' indicates that the width of the sight picture is 390 feet at a distance of 1000 yards. Usually only magnification below 5X works well for night binoculars. Mars and Venus on the horizon are a whole different picture when you can magnify your own vision.
Do not waste your hard earned cash on a pair of cheap ones. So, get a good pair of binoculars and enjoy the birding.
