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.

What Are Varifocal Glasses?

Varifocal glasses, also known as varifocals, varifocal lenses, PALs, or progressive lenses, have a gradual change in strength from the top of the lens to the bottom with multiple focal points in between. This allows you to see all distances and focus points through just one lens. Varifocal lenses are typically used when you have two prescriptions, one for distance and one for reading.

There are three regions of a varifocal lens which are distant zone, intermediate zone and, near/reading zone. Usually, the upper portion of the varifocal lens is the distant zone and the bottom portion of the varifocal lens is the near or reading zone.

One of the benefits of varifocal glasses is that you do not need to prepare 2 separate pairs of glasses or need to switch between frames for different vision needs.



What are progressive lenses?

Progressive lenses, also called progressive multifocal lenses, are lenses that have multiple focal points. If it is divided from the focal point, the lenses can be divided into single focal lenses, bifocal lenses, and multifocal lenses. The original intention of progressive multifocal lenses is to provide natural, convenient, and comfortable correction methods for presbyopia patients. A pair of glasses can see far away, close up, and mid-range objects. After wearing them, one pair of glasses is equivalent to using multiple glasses. Because of the different nature, characteristics and applicability, progressive lenses are more expensive than single vision lenses.


Disadvantages of polarized sunglasses

Polarized sunglasses have many benefits. However, in some cases, non-polarized lenses are a safer choice. On cloudy days, drivers find that non-polarized sunglasses are better than polarized sunglasses due to the lack of glare and extreme sunlight.

Driving with polarized lenses after snowing can be dangerous for drivers. As the glare of polarized sunglasses is blocked, ice or snow on the road will not be visible. In this case, the advantages of polarized sunglasses will become the disadvantages that may cause accidents.

In addition, when driving along a dark road with few street lights at night, wearing polarized lenses will make it harder to see the road conditions because they dim the available light better than non-polarized glasses. Of course, in low-light conditions, it is best to avoid wearing sunglasses completely while driving.

The most significant disadvantage of polarized sunglasses is that they do not perform well on digital screens and displays. They can cause the images and information on the LCD screen to blur or disappear at certain angles. Don’t wear polarized sunglasses to use these devices while driving.

Can you adjust your glasses by yourself?

If your frames are not suitable, adjusting your glasses at home may be easier than you think. You can solve the most common problems in the frame by yourself, but sometimes taking your glasses to an optician is the best thing to do. Of course, if your problem is your lenses, that's something you can't usually fix at home.
