Abstract
An optical sighting system includes at least one optical channel with which there is associated at least one reticle. The reticle includes at least one mark which demarcates a blind spot, which is visible to an observer using the optical sighing system and which is centered approximately about a centering point that is situated substantially at a distance which is representative of a sighting angle of between 13° and 18°, with respect to a predetermined direction of observation along a first direction. This first direction is representative on the optical sighting system of the direction passing substantially by the centers of the eyes of an observer who is using the optical sighting system.
