Vintage eyewear refers to eyeglass frames that are more than 20 years old. Vintage eyewear speciality shops sell used frames collected from old optical shops and other sources, some of which have never been worn.
Popular vintage eyewear styles include the browline frame, which was popular in the 1940s and has a plastic upper frame and metal lower frame. Cat's eye glasses, wayfarer frames made by Ray-Ban and other manufacturers and often used in sunglasses and so-called "granny glasses," which are round metal frames made popular by John Lennon are all sought after by vintage eyewear fans. Oversized plastic frames are still made today for sunglasses, and the vintage versions were originally popularized by Jackie Kennedy are still prized today.
