We're often asked, polarized or non-polarized. It's all about glare. If you're planning on using your Ombraz in the snow, on the water or in places where there's lots of glass like cities or on the road, go polarized. If glare isn't an issue, go for non-polarized. They're the same awesome lenses, just without the polarized film.
Both polarized and non-polarized lenses offer UV400 protection.
