Retro-vintage eyewear is characterized by frames conveying a '50s, '60s, or '70s look. Themes typically found in retro-vintage style eyewear include thick rims and double bridges. Wayfarers and cat-eyes are common frame shapes associated with this style.
The term retro refers to the style of a frame rather than the shape of a frame. Certain shapes such as the ClubMaster style were created by Ray-Ban in the 1950s. The ClubMaster is characterized by bold, plastic coverings that cover the top half of the lenses in order to mimic the wearer's natural browline. The ClubMaster Eyeglasses and Sunglasses style is retro. They are known for being a part of the most recent “hipster style”, which has brought back older rock and roll fashion pieces from the 50s and 60s.
Another retro style of frames is the cat-eye. The cat-eye style is known for its distinct frame front shapes. Each lens comes to a pronounced point at the temple endpoints and mimics winged eyeliner. A feminine style in the 1950s, cat-eye style has recently made a comeback in many popular women's frames today. They were conceived in the 1950s to complement a woman's facial features and could be seen on many famous, female celebrities.
Finally, vintage, when referring to clothing, describes an older piece of clothing from, let’s say the 1960s, that is being worn today. When it comes to eyewear, vintage eyewear describes a style of eyewear that is made to look older, but in reality, was not made in the 1960s. A great example of vintage eyewear is the Aviator. Created in the 1930s, it is still possible to find real, vintage Aviators that were made back in the 1930s, or you could buy Aviators that were made today, styled like those from the 1930s and call those vintage as well.
