History of browline frames
Shuron, an American eyewear brand with a history of more than 100 years, is generally considered to be the creator of browline frames. Browline glasses were very popular in the United States in the 1950s and 1960s. By the 1960s, as the shapes, sizes, and colors of plastic glasses increased, the popularity of browline frames gradually declined. In the 1970s, the hippie subculture led to a rapid decline in the popularity of eyebrows, which was considered conservative.(https://www.koalaeye.com/collections/browline-eyeglasses)
Until the 1980s, Bruce Willis wore tinted lenses in the Moonlight series, and the demand for browline sunglasses surged. In response, Ray-Ban launched Clubmaster, a traditional browline frame with sunglasses lenses. However, in the 1990s, browlines were strongly opposed by consumer culture. They are also regarded as too nerdy and conservative. Until the 2010s, the influence of the TV series Mad Men and the fashionable subculture inspired people to fall in love with the classic retro style of browline frames again.
Nowadays, with the progress of the times, there are more diversified choices in the material of the upper edge of the browline frames. On the whole, although the eyebrow frame is a bit serious, it has a calm and full nostalgic appearance, which is still the style that modern male gentlemen can't put down.
