Nano engineered lenses able optics that have higher resolution, wider fields of view, and are lighter. Nano lenses can have as many as 500,000 to 3.5 million layers. They will be lighter, shorter, clearer and stronger according to McKean. Currently the military is replacing the glass in the PVS-14 night vision units with the new techology. The glass version is 4.4 oz and polymer nano version is 2.9 oz. The new optics may debut as soon as the 2018 Shot show.
