So the pvs14 i posted about the other day now has a black spec almost right in the center. It was a friends and it was flawless. He let me take it home for the night and try it out and everything was perfectly fine. Paid him the next day and that night I messed with it some more, perfectly fine. Put it up in a Pelican case and take it out today to test out an ir laser I bought and boom black spec right in the middle of the lens. What would cause that if it wasn't touched?
