Basically, binoculars are one type of telescope but unlike your typical telescope which can be called a monocular, it allows the user to view objects that are at a distance using both eyes. This means that you actually have two separate telescope with one designed for each eye so that you can get binocular viewing. Unlike the telescope and other monocular devices that use only one telescope to view your objects, binoculars allow the viewer to have a three dimensional viewing thereby promoting clarity and visual acuity.

Binoculars are relatively smaller in size such that they can be easily handheld and there are also many lightweight varieties that can be carried and stored very easily. When compared to monocular, binoculars are much easier to hold and they provide for a steadier viewing; since both hands are working it becomes easier to steady the device in a position that is more comfortable and in a stable position.

There are many different practical applications that you can use binoculars on whether you are using them for a hobby or for professional purposes. Binoculars are a basic instrument of trade for hunters and birdwatchers while they can also become very handy for professional sporting events such as those where the spectator has to be far away from the center of action. When you come to professional considerations, binoculars are an essential in seafaring and they are also a must have tool for scientists such as meteorologists, geologists or other environmental professions; there are also specialize binoculars that are used for military applications as well. Visit any major tourist attractions such as the Grand Canyon and you will come across huge swivel mounted binoculars or for that matter even a monocular that have been placed strategically so that tourists can enjoy some attractive features that are far away.

Binoculars employ a series of prisms that magnify the image for the user; there are large ocular lenses found at the far end that will take in all the light it is going to capture. Normally, the image is inverted so that the eye will see the image upside down and this may not be useful at all. There is therefore a prism that is placed between the first lens and the human eye that flips the image over. The image will also need to be focused and it can be done through the use of the center focus adjustment knob or by perhaps moving individual eyepieces to put them in line with your eye.

Porro prism binoculars are usually the most common type; they use an ocular or positive eyepiece to view the images. The system comes with a series of mirrors or prisms that invert the image so that it appears upright. The porro prism system also allows for greater magnification that improves the image quality and this is what makes them popular.
