OP, if I remember correctly the old AN-PVS 5's had a screw on filter on each eye piece called an "essler filter". It was supposed to prevent damage to the goggles from laser range finding devices of the time (a GLDD for instance) that were not eye safe. It pevented burnout of the optical electronics. Just throwing that out there for what it's worth
