Binoculars come in different sizes and shapes to suit different purposes. Binoculars are two identical telescopes placed side-by-side that are designed to point accurately in the same direction.
While cleaning your binoculars, you should take care to see that no cleaning mark or scratch is left on the surface of the lens. Even though they are pre-moistened, they do not leave any trace of residue-causing streaks on the expensive lenses. Any larger than about 9 or 10, and the natural shake of the human hand will be magnified to such an extent that the image becomes difficult to see, and a tripod will be required.
Folding in the eyepiece between observations will protect the eyepiece against scratches or other inadvertent damage. A monocular was a perfect device to locate and identify riders from far off, and to determine from their banners or colour whether they are friend or foe. Field-of-view is determined by magnification and the focal lengths of the objective and eyepiece lenses.
Most binocular lens protectors are replaceable. The anti-reflective lens coating on compact binoculars reduces glare to a great extent. If your application is bird watching, theater or sporting events, a low powered binocular will suffice in most cases.
You want to keep these for years to come so you might as well be comfortable. Check the seals periodically, and bring your binoculars in for servicing if there are signs of cracks or leaks in the seals.
