Their standard lens index is 1.57 and for extra cost you can upgrade to either 1.61 or 1.67 index. Is this the thickness of the lens?
I would have coke bottole lens if I don't pay the extra money to get the thinnest material possible. and I don't see anything on this webiste about thickness, etc. options.

I'm not sure what the index means. But I took it as to how thin or thick you want the lense to be.
