Glacier Category 4 Oakleys

[O-Skier]

So today we had a customer come in saying she'd heard a rumor that Oakley were making Glacier glasses, to be used at high altitude.

I've never heard of Category 4 lenses from Oakley. From what I understand Glacier glasses need to be under 10% light transmission. But the black iridium polarised lense is 9%. Apparently UV power increases 4% with every 1000ft.

Does anyone have anymore info on glacier lenses and if Oakley have any?

Thanks Chaps

I had heard something like this a long long time ago. Oakley making special darker tints for mountaineering.

It's probably been more than 10 years since it last came up though.

Wouldnt the BIP lens be a glacier lens, since its under 10 percent?

Don't forget VR28 BIP also.

Yeah that's what I thought. Unless there's other criteria for like altitude and pressure? And I'm not sure how reliable the source was.
