While mountaineering glasses such as Julbos work well in most cases, I do like the extra protection afforded by goggles. My guess is that youll be around helicopters some, and goggles afford much better eye protection when dust and snow start to blow around. Same goes for very high winds.
Youll be best off with a polarized pair of goggles (to reduce glare) in a rose/brown lens tint to block excessive brightness and increase contrast when its cloudy. Zeals Detonator ($139; zealoptics.com) fills that bill, with a polarized lens and high-contrast tint. Theyre kind of pricey but are very comfortable and effective. Smiths Phenom goggles ($169; smithoptics.com) also offer polarized lenses, with a tint similar to the Zeals. The Phenoms also have a spherical lense for a wider field of view, and a vent you can open or close.
In the non-polarized arena, Bolles X9 OTG goggles ($50; bolle.com) fit over eyeglasses, and have a citrus lens for a good mix of contrast and light transmission. You might also like Oakleys Crowbar goggles ($125; oakley.com) because they come with three interchangeable lenses: yellow for low light, persimmon for overcast days, and black iridium" for sunny days. That would be a useful thing for your trip, I would think.
All these goggles work with helmets, too.
Have a great experience!
