Ok, ever since I first started wearing Oakley and falling in love with the brand I have had many questions. Most of these questions are answered but there has been one that I have not had answered.

Oakley snowboard goggles like all of their lens are said to have exceptional optics. What sets them apart is polutinite, a very pure polycarbonate. The inner lens of the dual layer lens is a much lower and more brittle lexan lens. Now with that as the layer closest to the eye how does the optics meet the same standards as their other eyewear? Why isn't the light bent and optics lower with the lower quality material in the lens as well as the polycarbonate?

I hope my question is clear.

Also on a side note with impact test do you run the risk of cracking the inner lens without hurting the outer lens?
