A monocular appeared shortly after the creation of a telescope. Modern-day monoculars utilize both prisms and Keplerian optics. The main distinction that sets apart these two devices lies in the picture that is created - monoculars provide a 2D image, whereas binoculars create a 3D picture. Monoculars are chosen over their counterparts for two main reasons. The first one - it is required to have a lightweight compact optical tool. Even though present-day technologies allow to create binoculars that are compact and lightweight, a monocular of the same magnifying rate is always at least two times smaller and therefore lighter. The second one - it is impossible to use binoculars in some situations. Most frequently, monoculars are utilized by people with poor sight or without one eye at all. Monoculars, unfortunately, are not as diverse in their design as their counterparts, however, we offer a vast range of optical tools that will suit your specific need.
