I ran into some ray ban sunglasses that looked a lot like carbon blades. I didn't purchase them but here's an example online: http://m.ebay.com/itm/301182885489?nav=SEARCH Rimless style, ultra thin and light weight arms, and straight stems. Looks like the raybans retailed for $239. I saw them at a store for $80. Of course the oakleys have more refined design, have superior lenses and might be lighter but is all that worth $400? We all know that rayban and oakley are own by the same company. Looks like the way they see it, if it fails under one brand they could always market it under another. I don't mean to rain on anyone's parade about the Caron blades since there have been some positive feedback on them. I just wanted to get to the bottom of this. If anyone has both pairs, some side by side pictures would be very helpful.
