Binoculars have two specifications marked on the body of the binocular in the form of 7x 50, where the first number represents the magnification, in this case 7 times, and the second the aperture ,50mm in this case. Many night vision binoculars work similar to digital cameras, they have a built in flash. Binoculars are just more comfortable to look through and hold steady because both hands are usually used. Even though they are pre-moistened, they do not leave any trace of residue-causing streaks on the expensive lenses.
All light transmitting surfaces are covered with multi-coating to increase brightness. For most uses, look for a objective diameter that is five times the magnification power.

Roof prism binoculars are so much easier to water and fog proof because of internal focusing. Low light uses such as hunting, birding and astronomy require larger objective lenses.
