Just had the chance to take my fly up to the ski slopes. My nephew took quite a few tumbles with it mounted to his helmet, and it seemed to hold up pretty well.
While inspecting the lens though, my heart sank a bit when I noticed several scratches on the glass cover. They seemed to buff right out with a lens cloth. I am noticing a clear film a lot like those on polarized sun glasses. Is this what is keeping the glass from becoming scratched?
Any tips on caring for this glass cover, and how easy will it be to replace this cover if it does become scratched or broken?
