Vintage usually refers to an item that has the feel of a certain era.

Strictly speaking, it refers to items dating from 1918 to 1978. However, in modern times, it broadly refers to collector's items that have a sense of an older era or items that show the passage of time.

In terms of eyeglass design, it generally refers to glasses with textured tones, such as tortoiseshell patterns, browns, and deep greens.
