About Porro Prism Binoculars:
The prism system of a binocular reduces the size needed to contain a long optical path and turns what would be an upside-down image right-side-up. In porro prism binoculars, the objective or front lens is offset from the eyepiece. Porro prism binoculars provide greater depth perception and generally offer a wider field-of-view.
