A collimator sight is a type of optical sight that allows the user looking into it to see an illuminated aiming point aligned with the device the sight is attached to, regardless of eye position (with little parallax).[1] They are also referred to as collimating sights [2] or "occluded eye gunsight" (OEG).[3]
