An optical system for distinguishing features of a target. A light source is located at a source position for generating a plurality of light rays emanating from the source position. A lens is positioned in front of the light source position. The lens has a first surface for receiving light rays emanating from the source position and a second surface, opposite the first surface, for outputting the received light rays. The first and second surfaces are separated by a thickness. The second surface having a first clear area for passing a first group of light rays through the lens. The second surface further includes a treated that is area separate from the first clear area. A method for treating an optical lens. A lens substrate formed of clear material is provided. The lens substrate has a first surface, a second surface opposite the first surface, and a thickness represented by a distance between the first and second surfaces. A treated area is formed on a portion of the second surface of the clear material. After the treated area is formed, the second surface includes the treated area and a separate first clear area different from the treated area.

[ What is claimed is:] [1.]1. A system for focusing a light beam, comprising:a housing having an exterior and an interior, wherein the interior includes a sealed cavity filled with a deformable pliable gel lens that receives and focuses light rays, wherein the deformable lens has an outside portion that extends outside of said housing, which outside portion contacts the exterior, wherein a focal length of the deformable pliable gel lens changes in accordance with application of a deforming force to the deformable pliable gel lens, the sealed cavity having an inlet through which the deforming force is applied to the deformable pliable gel lens.
