Corrective sight for firearms

Abstract

A sight system for a firearm may comprise a corrective sight. The corrective sight may be disposed adjacent a first end of a barrel of the firearm. The corrective lens may comprise an aiming tool, such as a reticle lens. The sight system may comprise a front sight disposed adjacent a second end of the barrel of the firearm. The corrective sight may comprise an optical lens with a positive optical power. The positive optical power may be configured to provide substantially clear vision of at least one of a target, the aiming tool, an indicia of the aiming tool, or the front sight when viewed through the optical lens. The sight system may comprise a retaining body configured to house at least a portion of the corrective sight. The sight system may comprise a mounting element configured to mount the corrective sight the firearm. The sight system may comprise the firearm.

         6 . The sight system of  claim 1 , wherein the optical lens comprises a first region and a second region, the first region having the positive optical power and the second region having an optical power less than the positive optical power of the first region and greater than or equal to zero. 
     
     
         7 . The sight system of  claim 6 , wherein the first region comprises a lower region of the optical lens relative to the firearm and the second region comprises an upper region of the optical lens relative to the firearm. 
     
     
         8 . The sight system of  claim 6 , wherein the first region comprises a first material and the second region comprises a second material different than the first material. 
     
     
         9 . The sight system of  claim 1 , wherein the positive optical power is from greater than 0 diopters to 10 diopters. 
     
     
         10 . The sight system of  claim 1 , wherein the positive optical power is adjustable. 
     
     
         11 . A sight system for a firearm, the sight system comprising:
 an aiming indicia, comprising a rear iron sight having two spaced apart sight elements defining a rear sight gap, and a front iron sight configured to be aligned with the rear sight gap, wherein the rear iron sight sight elements and the front iron sight each include a transparent optical lens disposed on a rear side; and   wherein each optical lens has a positive optical power configured to provide substantially clear vision of the aiming indicia when viewed through the optical lens and, wherein each optical lens is configured to assist a firearm user with a vision condition aiming the firearm at a target to bring into focus the rear iron sight and the front iron sight at the rear sight gap.   
     
     
         12 . (canceled) 
     
     
         13 . The sight system of  claim 11 , wherein the optical lens comprises a polarization region. 
     
     
         14 . The sight system of  claim 13 , further comprising polarized eyewear configured to cooperate with the polarization region of the optical lens to provide substantially clear vision. 
     
     
         15 . The sight system of  claim 11 , wherein the positive optical power is configured to bring an image of the aiming indicia in focus at a retina of an eye of a user of the firearm when the user views the aiming indicia through the optical lens. 
     
     
         16 . The sight system of  claim 11 , wherein the optical lens comprises one or more of a convex lens, a plano-convex lens, or a converging lens. 
     
     
         17 . The sight system of  claim 11 , wherein the optical lens comprises a first region and a second region, the first region having the positive optical power and the second region having an optical power less than the positive optical power of the first region and greater than or equal to zero. 
     
     
         18 . The sight system of  claim 17 , wherein the first region comprises a lower region of the optical lens relative to the firearm and the second region comprises an upper region of the optical lens relative to the firearm.
