Hi there. I bought a pair of black polished grey lens frogskins from Germany.from this seller Oakley Frogskins (OO9013 24-306) | UV-Stars - exklusive Marken-Sonnenbrillen mit Style I am not sure if it is genuine or not. Also when I look the lenses indoor on white neon lens I see rainbowish colors on the surface. Checked for glares and there was more glares than my cheap 10 dollars sunglasses. So is it possible grey Oakley lenses to have that problem. Please check this on yours glasses under the same conditions and let me know.
