We shall be looking at how binoculars work. You'll need to choose the magnification power of your binoculars.
Perhaps you are planning a sight-seeing trip to some exotic location. So having a small and handy binocular that you can always carry with you is ideal. If it just for the kids to play, then go with a less expensive model that they will not break easily.
The coating reduces glare and protects your eyes from UV rays, and increases the definition and clarity of an object. Size is dictated by the objective lens. Since the advent of the original coating, the technique has been refined, and there are several grades of lens coating available.
But mass production and better technologies have brought down the price substantially, so that the common person can afford them. Galactic clouds and star clusters look dim when viewed by the naked eye, but with binoculars they are much clearer. The more important consideration should be the field of view.
Binoculars are the perfect accessories for hiking, fishing and hunting. The ones in the two to five hundred dollar price range are generally sufficient for bird watchers.
