If anyone ever gets the opportunity to climb aboard an Oakley Rolling O lab or stop by HQ they demo their lenses against others and you will see why their is a difference. I have a few different brand aftermarket lenses, that actually cause a star like effect when light hits them directly, so in essence my frames only have original lenses in them I had to try aftermarket to see for myself......
