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.

It requires the operator not only to have the knowledge of ophthalmology but to have the basis of children's ophthalmology and children's optometry. And they should be an optometry expert. Dealing with children's refractive problems is as much an art as a technique.

What Is an Aspherical Lens?

An aspheric lens is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens.

The aspheric lens’s more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens. A single aspheric lens can often replace a much more complex multi-lens system. The resulting device is smaller and lighter and sometimes cheaper than the multi-lens design.

Aspheric lenses are flatter than traditional lenses, but they still offer the same vision-enhancing benefits. They have a more attractive profile because there is less curvature. In addition, aspherical lenses have a more complex front surface with a gradual curve so that they can perform better by improving the way light refracts onto the retina.

Besides, most aspherical lenses are high-index, which, when combined with the aspheric design, offers a slimmer and lighter option for people who wear glasses so as to improve the look and feel.
