The Javelin CUU needs its specially designed case to protect parts like the hand grips, afocal lens

At 1X magnification, the Ugo night channel offers a 40 [degrees] FOV - a figure that reduces to 10 [degrees] if magnification is increased to 4X via an afocal lens
adapter which can be "fitted in the field by the user." At 1X magnification, the Ugo can "recognize" a man at a range of 300 m in 10-lux lighting conditions.
D-Stress is based on Safilens' patented afocal lens
design for presbyopic patients, but is instead focused on reducing eye strain commonly associated with daily activities that overstress proximal vision.
