Revo once was a great brand..before they were bought out by LUX. Now, thanks to Luxottica, the lame Lenscrafters handles the retail servicing of problems with Revo lenses. I took a pair of broken Revo lenses to lenscrafters. The manager offered me some cheap generic "blue-tinted" polarized, poly-carbonate lenses for my $50. This was his solution to Revo no longer making this particular pair of lenses that I had. I was too tired to argue the fine distinction between Revo glass lenses and his cheap polycarbonate knock-offs. Wow...is this how LUX trains its employees to recognize "branding" and good service?? Revo (LUX) just lost a good, loyal customer. I will think twice before buying any Luxottica brand sunglasses again.
