i dont buy expensive sun glasses.... i dont have luck with them..... the most expensive pair i bought were $60 polarized glasses from a local outdoors shop..... my ex broke up with me one night at random and i had left them at her house apparently she threw them away without ever asking if i wanted them back..... most of my other pairs aether get lost, broken, stolen or fall off my head XD so you guys can keep your expensive eyewear ill keep to my $20 polarized wal-mart sun glasses lol
