How can I tell if my sunglasses are polarized?

I just got a pair of sunglasses. They are white Oakley Gascans.Can anyone let me know if they are polarized?

You can find a reflective surface like water, and hold your sunglasses in front of you.Then view the surface through the lenses. And then rotate the glasses to a 90-degree angle.If your sunglasses are polarized,you will find the glare reduced when you view through the lenses.

Well, it is good for you to have got a pair of Oakley Gascans sunglases because they look so awesome and could make you appear to be quite cool. Anyway, as you can see, nowadays, sunglasses are becoming more and mroe polarized and Oakley Gascans are actually polarized on their website. And you could get further information on their product certificate. I suggest that if you buy sunglasses in a store, you should ask question clearly before paying the bill.
