The only double FOV in the world!
The idea of bifocal sights was inspired by nature itself: we tried to reproduce the features of the eyes of an eagle. While soaring in the sky, eagle has the capability to overlook a very large space in a very small scale. Just the central part of its eye with a large increase transfers narrow central part of the field of view in the center of their retina. Turning its head, the eagle can see any part of the field of view in more detail. In the optical terms, the eye of eagle has two focal lengths (two zoom) simultaneously.
