TECHNICAL FIELD [0001] The present invention relates to aiming sights and more particularly to a sight that is only visible to the shooting eye. BACKGROUND ART [0002] Modern firearms are inherently very accurate. The ability to shoot accurately depends on accurate pointing or aiming, and often requires rapid acquisition of the target. Known sights commonly have a front sight in the form of a small bead sight near the muzzle or front of the firearm barrel. Such sights can also have a rear sight near the breach or rear of the firearm barrel. [0003] Conventional bead sights have several shortcomings. Bead sights are difficult to see in low light conditions and against dark backgrounds. When sighting with a bead sight, a shooter can raise the eye too high above the barrel so that the firearm points higher than intended. Many people are cross dominant, shooting right handed and having a dominant left eye, or vise versa. Such cross dominant people may unintentionally use the dominant eye instead of the correct shooting eye to align the bead sight with the target, so that the firearm points laterally away from the target. These shortcomings of the bead sight are particularly apparent when rapid target acquisition is required such as shotgun shooting of bird, trap or skeet, or pistol firing at moving targets. [0004] One improvement to front sights relative to the bead sight is the use of a small artificial light source to replace the bead sight. The light source can be electrical or photo chemical. Front sights with artificial light sources are relatively complex and require periodic replacement of the light or power source. [0005] Another improvement is the use of a light-gathering tube or rod, generally of a colored plastic material, to replace the bead sight. Such light-gathering rods have a length many times the cross sectional dimension, and thereby have a peripheral surface area much greater than the end area. Light is absorbed through the peripheral surface and emitted through the end of the tube. A front sight with a light-gathering tube is easily seen in low light conditions and against a dark background. [0006] U.S. Pat. No. 3,362,074 to Luebkeman et al. discloses a front sight with a lens and a very small distinct object mounted forward of the lens at the focal point of the lens. The lens changes the direction of light from the object so that the shooting eye can see the object while the non-shooting eye cannot see the object through the lens. Luebkeman discloses the object as a small colored dot, a small electric light or a small piece of fluorescent material. [0007] U.S. Pat. No. 5,862,618 to Brown, and U.S. Pat. No. 6,014,830 and U.S. Patent Application Publication No. 2003/0079396 to Brown et al. each disclose sights with a light gathering rod and an elongated hollow tube through which the light gathering rod is viewed. In the '618 and '830 patents the light gathering rod is at the forward end of the hollow tube, whereas in the '396 publication the light gathering rod is near the firearm muzzle and the hollow tube is near the firearm breach. [0008] U.S. Pat. No. 6,604,315 to Smith et al. discloses a sight that uses a diffraction grating. The sight changes color as the shooting eye moves up and down or side to side relative to the barrel of the firearm. DISCLOSURE OF THE INVENTION [0009] An aiming sight includes a mounting base, and a light gathering rod and a converging lens on the base. The rod has a peripheral surface that absorbs light and a back end that emits the light. The lens is aligned with the rod and has a selected focal length. The lens is spaced rearwardly from the rod a selected distance that is slightly greater than the focal length of the lens. Lateral walls or a hollow tube on the base extend forwardly from the lens provide a means for blocking the view of the back end of the light gathering tube from the non-shooting eye. The lens redirects light rays emitted by the back end of the rod to converge near the position of the shooting eye so that the back end of the rod is only visible through the lens to the shooting eye and only visible to the shooting eye when the shooting eye is properly positioned relative to the gun barrel.
