A holographic sight is a type of optical sight used on firearms that projects a holographic reticle onto a lens. This allows shooters to see the reticle superimposed on their target, providing quick target acquisition and improved accuracy. Unlike traditional scopes, holographic sights offer a wider field of view and can be used with both eyes open, enhancing situational awareness. These sights utilize a laser to create a three-dimensional image of the reticle, which remains in focus regardless of the distance to the target. Holographic sights are popular among military and law enforcement personnel, as well as recreational shooters, for their speed and ease of use in various lighting conditions.
