Ray Ban Clubmaster, which is popularly known as Browline glasses. Browline glasses first became popular in the 1950s and 1960s. The name derives from the fact that the bold upper part of the frame, frame the lenses in the same way that eyebrows frame the eyes.
Shuron Ltd. manufactured the Clubmaster glasses in 1947 under the name of Ronsir. The design of Clubmaster glasses is combination of metal and fiber or aluminum, the glasses are fixed in metal frames, which insets into fiber brows and are attached to the earpiece of glasses.
After 20 years Ray-Ban redesigned the bowline glasses into clubmaster by making them lighter and cooler, and also came into four different colour options.
Malcolm x used to wear Browline glasses. The trend began in the mid-2000s but continues to hold firm. The Clubmaster were not popular until Bruice Willis wore them in a hit television series Moonlighting. It went on the third position for popular glasses after Wayfarers and Aviators in 1980s. The trend began in the mid-2000s but continues to hold firm.
The Clubmaster has become a favorite for more casual outings. I own two of the Browline one with prescribed lenses and one with black polarized lenses.
