I have worn a less expensive pair of Randolphs before and the only reason I purchased these was because I thought they looked cool. So I very happy to discover that this lens is far superior to any I have worn before. The clarity is amazing. No distortion. When sunglasses cost a lot, I feel it usually due to a name or hype. Not the case here. These are legitimately different. A very pleasant surprise that I found by mistake. I feel like I need to research these further to figure out what makes them so different.
