Abstract: The invention encompasses firearm sights configured to eliminate the effect of parallax a shooter would otherwise experience when aiming a firearm at a target. The firearm sight utilizes a rear sight vane and at least one occluder positioned so that the occluder interferes with or substantially blocks a shooter's line of sight for the shooter's non-aiming eye without obstructing the vision of the correct eye with which the shooter should be aiming.

Abstract: The invention encompasses archery bow sights that comprise at least one lens configured to eliminate parallax. In one aspect of the invention, the site includes at least one plus power ribbon accommodating lens supported by a support means. A reference means is forwardly mounted in front of the lens so as to be located along the archer's line of sight between the lens and a target when the archer is shooting the bow. The optical lens of the sight eliminates parallax so that the archer's eye does not need to realign his line of sight between an archery peep, the reference means, and the target when the archer changes elevation of the bow.

Abstract: An optical sight for use in aiming firearms, archery bows and other visually aimed devices. The sight includes a rigid supporting frame. The frame supports an optical lens that is ground to produce a magnified virtual image of a front sight. The front sight image is located with a top edge of the lens along an image line of sight that is substantially parallel to the operative axis of the device. The eye does not have to accommodate by focusing between a front sight, rear sight and target since the target and sight image remain clear. The front sight image will "disappear" from the visual boundaries of the lens when elevational adjustment of the device is made, without obstructing view of the target.
