At one of my previous jobs there was a guy with really expensive looking glasses. Something like gold plated aviator type but really fancy looking. Job was 1000% not as well paid to buy anything like this. I have asked him about his glasses and he gave a nice pro tip: Just buy used frame and put lenses inside yourself.

Makes sense. Used frames are dirt cheap. Senses are not so expensive for a simple sunglasses with no dyoptres. Can go fancy and get some scratchproof polarized lenses and not overpay for a $500 raybans.

Also, afaik, rayban owns pretty much any other glass brand. So, pointless to get rayban for so expensive.
