Today everyone has glasses – and not alone. Often, ophthalmologists recommend wearing sunglasses even in cloudy weather. At any time of the year, these glasses are well shown to most of us. In fact, many have to wear sunglasses in the winter to protect their eyes from the brilliance of the sun in the snow.
In addition to eye protection, sunglasses also provide an excellent opportunity to add a style element to your look. In order to wear such glasses correctly and to the place, it is necessary to learn a few simple but clear rules.
HISTORY OF SUNGLASSES
For hundreds and thousands of years, people frowned at the bright sun and always somehow found a way out of the situation: even in prehistoric times, the Eskimos used protective plates of walrus bone to cover their eyes from the bright rays of the Arctic sun. It is also known for certain that the Roman emperor Nero used sunglasses to observe gladiator fights. True, emeralds acted as glasses, which probably distorted the review, but still gave long-awaited peace to tired eyes.
Nero was not the only one who used the reflective properties of minerals: the Chinese used quartz plates smoked over the fire to protect their eyes from the blinding sun. Moreover, the Chinese first started wearing sunglasses on the premises, which led to the birth of a number of spyware tricks in government circles. Judges in China wore dark glasses in order to conceal their faces in front of witnesses during interrogations. In continuation of this tradition, government agents on the line of defense or attack used the same disguise, and not because of their weak eyesight. Sunglasses have become an integral part of the image of the predecessors and followers of James Bond: intelligence officers and bodyguards, whose task was to protect and protect influential people.
The glasses helped them not to lose their vigilance and attention to detail both indoors and in open spaces so that when you exit, the street does not have to spend even a fraction of a second to adapt the view to bright sunlight.
As early as 1752, someone James Eyskof experimented with colored lenses and placed them into frames for glasses, as a result of which he noted that the lenses of blue and green shades had corrective properties for people with impaired vision. It is curious that these experiments had nothing to do with the sun protection properties of such lenses, although in fact they became the prototype of the sunglasses of our days.
With the wide spread of infectious diseases in the early twentieth century, doctors prescribed wearing glasses with lenses of amber and light brown shades due to the extreme sensitivity of patients to daylight. In fact, they became the first modern sunglasses – namely, sun protection, not protective, as, for example, the pilots. The release of such glasses allowed people to learn to hide their eyes behind dark lenses and thereby reduce the painful or just uncomfortable exposure of the sun to the eyes.
By the middle of the XX century, sunglasses were widespread. American movie stars wore them everywhere to hide from obsessive fans, and from Hollywood this trend spread throughout the world. Dark, with a large frame, such glasses have become the standard of style, and the growing demand for them has become intensely satisfied by major manufacturers of accessories for men and women. Since then, sunglasses have been worn not only as sun glasses, and every person interested in fashion and style wants to have more than one pair at his disposal. Three-quarters of people who wear sunglasses regularly have no vision problems and, therefore, wear them purely as an accessory.
In 1936, lenses made of polarized glass were patented, and this further stimulated the development of the market for sunglasses. Airplanes began to wear them over their aviation goggles to make the review clearer and to hide from the scorching sun rays. In the 80s, Tom Cruise’s icon of style in his stellar role in the movie Top Gun appeared in the now well-known model of aviator glasses by Ray-Ban, which took the opportunity and issued a patent for them.
