Style of Binoculars – Porro or Roof Prism Design Binoculars come in two distinct styles in which design is dependent upon the type of prism system used. The image that passes through a binocular is upside down (a function of the lens) and needs to be corrected.
Porro Prism Systems: the objective lens is offset from the eyepiece. Light is redirected through the binocular internally. The result is a shorter, stockier shaped binocular. In general, porro prism binoculars offer a wider field of view. Most zoom binoculars use the porro prism system for this reason.

Focusing your binoculars: Most binoculars have a center focus wheel and an independent right diopter eyepiece to account for small differences in the strength of each eye. Please follow the steps below to focus properly: 1. Adjust the interpupillary distance.

Never try and force an eyepiece if it was not designed to turn. This may seriously damage your binocular. Roll-Down Eyecups Your binoculars may be fitted with rubber eyecups designed to exclude extraneous light. If you wear eyeglasses, you may be able to roll-down the eyecups. Some binoculars are outfitted with twisting eyecups which raise and lower the eyecups.
