Training and ate shit against the side of a vehicle :D

Flip the PVS31A down and see what looks like a smudge on the glass that won't rub off. Kept going for the rest of everything. When done, I was able to get them in the light and see that one of these is now totally cracked.

This screws into the ocular, not the objective and they seem to be a tint of purple.

I'm guessing a filter and/or sacrificial lens? Problem is, searching for either of this for a PVS31A doesn't seem to come up with anything.

What are these and where do I get replacements?

If you need a single Screw in Diopter order BNG-080-A4, If you want a set of two order BNG-014-A4.

And no tube damage?  I’m looking at bnvds myself and afraid of doing this very thing.  I’d always be happy to replace a lens but the tubes would make me cry probably.  Actually.
