The Evolution of Sunglasses

"
The first sunglasses were discovered in the 12th century. The absence of sun before could be explained by the omnipresence of the hats. We have revisited glasses of the tinted disparate way in history.

The appearance of the first sunglasses
Chinese sunglasses is in the time of antiquity that we find in the first traces of tinted glasses. According to some writings, Nero, the Roman emperor, used emerald blades to watch gladiator fights. Was it to correct his myopia or to see his sight? In the thirteenth century, another form of glasses appeared in China. Indeed, Chinese judges have freed themselves from their judgment, but they have also gone to the sun.

James Ayscough: the inventor of UV filters

James Sky (born 1759) was an English thinker and designer and maker of scientific instruments. He was exposed from 1743 to 1747 by a theory maker named James Mann. Is James is famous for his microscopes. His shop was in London between 1740 and 1759. Around the year 1752, James Sky started the show with double-hanged side pieces. [1] Although he made clear lenses, he recommended dyeing the lenses in blue or green to cure vision problems. These tinted glasses are a preview of sunglasses.

In February 1755, he began contributing to the Monthly Register of the Month for the Gentleman Magazine. This included barometric readings of pressure, and two temperature readings in the early afternoon and late evening. There was also a brief opportunity to know the weather of the day. It may begin with the record that the magazine is already owned, (as it was originally published in 1747, originally reported in English.) Initially, barometric pressure 1.

The year 1752 marks the turning point in the history of contemporary sunglasses. It is the Englishman James Ayscough who discovers a little danger UV filtration by seeking to improve the vision. However, the result is not conclusive and it is three centuries later that Sam Foster markets the first sunglasses. In 1929, he sold his first pair, the "Foster Grant" in the United States. The success is with go since we piloted especially for its pilots. The group Bausch & Lomb, creator of the Ray-Ban brand, also designs a special glass with very dark skin for the air.

The Triumph of Sunglasses
It is often stated that “nothing is new” to portray the idea that everything that we do and learn is, in one way or another, a recycled version of something that someone else has done before. I find this statement to be true everywhere I look, and in the instances in which it didn’t appear to be true, it was only because I hadn’t looked hard enough. Of course, there is nothing wrong with this. It seems only natural that we learn through imitation before we can then adapt what we’ve learned to something else by “standing on the shoulders of giants,” to borrow a metaphor. Even, at times, when our insights seem serendipitous or of our own accord, another has already come across the same concept before. Such was the case when, in 2008, a group from Tsinghua University in Beijing, China, passed an alternating electric current through a thin, transparent sheet of carbon nanotubes (CNTs) and discovered that it produced sound (Barras, 2008). With a bit of investigation, they found that such a device, called a thermophone, had existed for over a century but that the modern nanomaterial had simply made it much more efficient than those of previous generations. In fact, there is currently an entire field of physics called thermoacoustics that is undergoing a revitalization and progressing because of advancements in modern technologies such as lasers, computing, and very large scale integration (VLSI) that enables the manufacture and patterning of nanoscale materials. Thermoacoustic research shows promise for new devices as well as alternative takes on existing devices. Such devices range from biomedical imaging tools and sonar transmitters to engines to refrigerators.
  
Foster GrantSince then, sunglasses are quickly becoming popular. In 1936, a polarizing filter was designed by Edwin H. Land. Polarization removes reverb and Ray-Ban symbols. At the end of the Second World War, the Aviator Ray-Ban crossed the Atlantic with American soldiers and became popular in Europe. The liberation of France by the allies makes these sunglasses absolutely indispensable as a fashion accessory. A few years later, Mark Foster Grant, launch a major advertising campaign in Europe to sell the chic side of the sunglasses. It does not take more for it to become a classic fashion accessory.

Current fashion

To choose a good pair of glasses, it is necessary to take into account the shape of his face. If the round face, it is possible to accentuate this feature with a frame of the same shape. On the contrary to soften these proportions, we can bet on geometric shapes, angular or stretched. Faces of oval shape can afford all styles of sunglasses.

For faces with square, rectangular or elongated shapes, it is advisable to opt for oval frame sunglasses. They soften the features. Triangular faces can play on the color and details of the frame. A face in the shape of an inverted triangle is enhanced by sunglasses with clear shades and discreet frames. 

Today, nearly 80 years after the democratization of sunglasses, many styles have emerged. The must-have brands such as Ray-Ban, Persol or Tom Ford are today. Classic sunglasses are butterfly, retro or XXL style and must be constantly modified. But we are sure that sunglasses still have a bright future.
