Made For Running, Great For Beasting And Biking Description Purple Frame / Reflective Mirrored Lens STOP THE PRESS We got 3 batsh*t crazy emails about""Thanks, They're Vintage"" sunglasses. WELCOME TO CARL'S INNER CIRCLEWhat's the difference between vintage, antique & retro? Vintage: ""characterized by excellence, maturity, and enduring appeal; classic,"" with true vintage at 50 years old. Antique: ""an object having special value because of its age,"" at least 100 years old. Retro: ""Involving, relating to, or reminiscent of an earlier time; retrospective,"" imitating a style at least 10-15 years old. That means these sunglasses are retro but we named them Thanks, They're Vintage so you have to lie to everyone and say they're 50 years old. Good luck.
