The History of Clubmaster Glasses

Clubmaster glasses are a variation of the browline sunglasses made popular in the 1950s. The lenses of clubmaster glasses are typically held in place by a thin metal frame and are of a squared-off round shape.

Although many people believe that the Cubmaster glasses root back to the 1950s, the fact is that clubmaster glasses or clubmaster sunglasses as we know them didn’t come about until Bruce Willis wore a pair of Shuron Ronsirs browline glasses with tinted lenses on the TV series Moonlighting in the mid-1980s.

From that moment, browline glasses draw the public’s attention. By the 1960s, Ray-ban was a fairly large contender in the market and its owner Bausch & Lomb was one of the top manufacturers of browline-style eyeglasses. And then the Ray-ban launched the first browline sunglasses, called it clubmaster. Sales were enormous almost immediately and despite only coming out mid-80s, they still ranked as the third most popular style of sunglasses sold in the decade, next to Ray-bans Wayfarers and Aviators.

Then Ray-ban took every revision of the original 1947 Browline and began offering it as part of the clubmaster series. From bold brows to lightweight metal caps first introduced in the 1950s, the clubmaster offered a style that could fit elegantly on just about any face shape. After that, the clubmaster glasses have been popular for a long time.
