A binocular device is the one which you look over with both eye, to make things look greater. You can find binocular telescopes, binocular microscopes, etc, but the expression is usually put on a "field cup," which is small and light enough to carry to your eye with your palm, and that allows someone to see things that are a long way away.
The field goblet is really two pipes, or small telescopes joined up with together at the very top. Each pipe has a zoom lens at both ends. A zoom lens is a cup that let us light come through it.

Without light, you could never see anything. The light comes through the zoom lens in the bottom. That is called the target zoom lens. Whatever light comes through the target zoom lens is enlarged or magnified. In today's, or prism, binocular, the light moves directly in and strikes a prism.
A prism is a bit of glass trim at angles such that it forms sort of triangle. The prism transmits the light to some other prism beside it. From here the light would go to the zoom lens in the eyepiece, by which you look. The prisms are incredibly important because they change the way of the light.
As light from a thing enters the target zoom lens it is ugly, however, the prisms transform it right part up again. The prisms also are able to visit a wider view. The target lens is further aside than the eye, and the prisms bring the light inward to the eyepieces that are deeper along. A binocular is identified by its cover and its own field.

A "six-power, thirty-five" binocular (written 6x, 35) makes things look six times as large as they seem to be to the nude eye and comes with an objective zoom lens that is 35 millimeters in size (almost an inches . 5 across). The most readily useful binoculars for day-to-day use are six- or eight-power, and the best field on these is 50-millimeter.
