Binoculars have been around since the 1600's century after telescopes have been invented. People use to connect two telescopes together and in able to see with both eyes.

During the 1800's a porro prism binoculars were created that enabled greater depth perception and also spaced the eye pieces wider apart. These binoculars were more powerful than the standard ones before then.

The cheapest binoculars are porro prisms that create detailed images and good color views. These are big and wide and sometimes need to be re adjusted to work properly.

A more costly pair of prism binoculars are roof prism binocular. These binoculars are lighter and smaller but lose some light. An advantage to them is that they usually never have to be re-adjusted. These binoculars weigh much less. Many roof prism binoculars have coated lenses.

Coated Lenses help make a bright image by reducing the amount of light that reflects. With out this, the binoculars will create a hazy picture.

Most Binoculars are focused by moving a round wheel that focuses both eye pieces at once. More complicated binoculars require independent focus which requires each eye piece to be focused separately.

More expensive binoculars have image stabilization which dampen sudden movement. This means that binoculars with high magnification can be hand held when normally they couldn't. This feature is very expensive.
