Prizm lenses - weird stuff inside lens

[Jimbo1901]

Hi guys -

I just found this weird little white piece of something inside the lenses of my Flightdecks.

Its in-between the layers of glass so no way of getting it out - do anybody else have this??

Just checked. I got it too. No idea what it is tho.

I'm guessing it's a vent with a moister membrane to relieve pressure between the inner and outer lenses but keep condensation out. Smith IO/Xs have something similar but they put it on the actual lens surface versus being more discrete like oakley seems to have done.

I have the prism rose lens on my flight decks, haven't noticed that problem
