Binoculars truly do have a long story, they have been around since the 17th century, emerging shortly after the creation of a telescope. First devices utilized Galilean optics to magnify the picture, and later this method was replaced with Keplerian optics. However, since the 1890s prismatic construction was adopted and soon all binoculars utilized prisms. There are two main prism types utilized in modern-day binoculars: Porro prisms and Roof-type prisms. These prisms are different in functioning principle, but similar in purpose and both produce a comparable quality of an image.

When shopping for binoculars one must keep in mind that there are quite a few parameters that need to be monitored. These parameters are: magnification scale, FOV (field of view) provided, objective diameter, size of an exit pupil and distance to eye point, and also a close focus distance.
