There are many options from very sophisticated binoculars for surveillance or night navigation to simple binoculars for kids to have fun with. You'll need to choose the magnification power of your binoculars.
Binoculars are just more comfortable to look through and hold steady because both hands are usually used. Perhaps you are planning a sight-seeing trip to some exotic location. The "10" refers to the magnification power of the binoculars, that is, objects viewed will appear to be 10 times closer than when they are viewed by the naked eye.
It is a real treat for kids to go on nature walks or hikes with their parents, however we all remember how heavy the binoculars were for us as kids, right. In live theaters and concerts, audience members sitting in the back rows away from the stage use binoculars to get a better view of the stage.
The best result is achieved when multiple layers of coatings are applied, to the front and rear of the lens. The only negative review I have to offer that the lens caps are cheap and are nowhere near the quality of the rest of the binoculars. Using your binoculars outdoors will usually subject them to moisture.
But if you're into astronomy, you'll need a high powered pair. Binoculars are wonderful for any sporting events, or children's activities.
