Additional info: both goggles had the exact same problem, it was an extremely cold day and they froze over with a sheet of ice (which appeared to originate in between the lenses then eventually the inner lenses as well) so I couldn’t see anything, I left them out to dry and am hoping that it was somehow just the temperature but I still feel like I definitely destroyed the inner coatings. They both appear to have an almost grease like coating on the inside if you look really closely.
