1. An optical sighting device for assisting a user's eye in sighting a target with a firearm, the optical sighting device comprising:
a sight body having a proximal end configured to face the user, a distal end distal of the proximal end, and a longitudinal axis extending between the proximal and distal ends, the sight body including an inner surface bounding a field of view through which the user can visualize the target;
an alignment indicator arranged to assist the user in determining whether his or her eye is correctly aligned with the longitudinal axis of the sight body, the alignment indicator being disposed laterally outward of the inner surface, the alignment indicator being arranged relative to the inner surface such that the alignment indicator is not visible by the user's eye when the user's eye is in a correct eye alignment with respect to the longitudinal axis of the sight body, and the alignment indicator being arranged relative to the inner surface such that the alignment indicator is visible by the user's eye when the user's eye is in an incorrect eye alignment with respect to the longitudinal axis of the sight body.
