ABSTRACT:
A specialized lens powered to an eighth diopter with zero tolerance is incorporated into eyeglasses that improve a shooter's ability to sight a weapon upon a target. The lens is further tinted to enhance visual perception of the target, and is positioned such that the optical center coincides with the shooter's line of sight upon the target in a standardized shooting position. A kit which includes a set of lenses, a lens holder, and a tint selection board is provided to facilitate selection of an appropriate lens and tint.
