I know that Polaroid has been around for a while and they have actually invented a polarised lens. However nowadays it seems like a rather budget brand and does not have much recognition. Which is a shame because they are easily one of the best quality lenses and frames I have, and I do have Oakley, Persol, Ray-Bans, etc. Honestly, these Polaroids are not that expensive but quality and performance wise they are probably even better than Oakley. I also love the vintage look. I will be buying more of those!
