Clean Glasses Properly

If the glasses are dirty, don't just wipe them with other cloth. If you use some hard cloth to wipe, it is easy to cause scratches in the lens. Generally speaking, the following cleaning methods are all feasible.

1. Use neutral or alkaline cleaning agent. Remember, toothpaste cannot be used as a substitute for the cleaning agent for spectacle lenses. General optical shops also sell lens cleaners in small bottles, which are easy to carry.

2. Go to the optical shop for professional ultrasonic cleaning. General optical shops provide free cleaning services. The ultrasonic cleaning machine can fully clean every gap and groove of the glasses.

3. Rinse the lens with tap water. Hold the frame in one hand and the cleaner in the other hand. Rub it slowly against the lens, and then rinse it off with clean water. Then wipe it with a glasses cloth or let it dry naturally.

In addition to the glasses cannot be cleaned with alcohol, you should also pay attention to their placement for daily maintenance. Try to avoid putting it under high temperature, and avoid oily, smoke, etc. If you don't use them, put them in the glasses case.

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.



The arm length is an important part of the size of the glasses.

Spectacle frames are standard optical products. Just like people's clothes and shoes, they all have their own size. Usually, specs for the size of the glasses are on the inside of the temple, on the bridge of the nose, or on the label. In general, the frames of the glasses are marked with the width of the frames, the width of the bridge of the nose, and the length of the arm. For example, the inner side of the temple is labeled: 52口 18-135, indicating the lens width of 52mm, the width of the nose bridge of 18mm, and the arm length is 135mm.
