Abstract
An optical aiming device with a front sight and a rear sight. The front sight is in the form of an upstanding needle-like element or an illuminated fine spot. To prevent repeated accommodation movements of the lens of the eye during aiming of the weapon the rear sight comprises two prisms disposed at each side of the front sight. Each prism will produce an image of the front sight, said image lying at the same distance from the shot's eye as is the eye-front sight-distance.
