The employee at the vault said they too couldn't quite figure it out on their own pair and were too nervous to really try it on mine... they said they were waiting till one showed up in the store so they could mess around on that one lol.Mine are not accessible until Christmas but there was a card inside with a card to replace the lens. I think someone posted one in the thread. I got as far as lifting a nosepad!
I lifted the nose pad, but then I tried flipping the jaw out like backwards... but nothing, I put quite a bit of effort in and only got a sliver of movement.
