Hoping someone here can help me figure out what's going on with my goggle lenses. So far this season I've had 3 Oakley Prizm lenses (for Canopy goggles) develop very small bubbles in the anti-fog coating (on the inside of the lenses). Two of the lenses were used last year without issue; one of the lenses is new this year and has only been used for 5 days. The bubbles are too small for my phone's camera to pick them up, so I don't have a pic to share unfortunately.

I'm completely anal about taking care of my gear and am meticulous when it comes to goggle care. I never, ever touch the inside of the lenses, I let them air-dry after every day of skiing, and I keep my goggles in a zippered hard case I've been using for at least four years. I've been using Oakley goggles for eight years and have had many different lenses, and none have ever had this issue. I even make sure to stuff the microfiber storage bag inside the lens when I store the goggles so that the strap doesn't rub the inside of the lens. I've tried using different types of sunscreens this year, I'm using the same helmet I've used for the past two years, I haven't left the goggles inside a hot car, I haven't yard-saled and filled the goggles with snow... what's going on here?

Oakley's customer service is beyond fantastic and they've already sent me two warranty replacement lenses, but at this point I'm thinking I must be doing something wrong to cause this issue. Any ideas?
