Let's plunge you a bit into history.

Do you know how our ancestors protected their eyes from bright sun rays?

It turns out that even the ancient Eskimos knew how to protect their eyes from strong sunlight. At that time, several devices were invented for this. For example, they made narrow slits in wooden sticks or walrus bones. Such primitive glasses reduced the effect of bright sunlight, but did not filter it, and accordingly were very harmful to the retina.

The first device, which remotely resembled modern sunglasses, was found in the tomb of Pharaoh Tutankhamun. It was two of the finest emerald plates, joined together by bronze partitions.

In Japan, too, there were adaptations from bright sun rays, they were made from special straps, with attached eye flaps.

In France, during the time of Napoleon, the production of glasses for the army, which was going to fight in a sunny country, was established. By the way, after about a hundred years only, the glasses began to be produced for the purpose of selling. 

In the early 20th century, wearing sunglasses began to gain momentum. This was promoted by the silent film stars who protected their eyes from the bright cutting light of the film studio. 

Mass production of sunglasses began in 1929, when the American Sam Foster offered consumers their products under the brand Foster Grant. 

In 1936, the first glasses with polarized lenses, invented by Edwin Land, appeared and same time was established one of the more popular brands Polaroid, which in our days has a lot of popularity among people who care about the health of their eyes.

It was from the 30s of the last century that a triumphal procession of sunglasses began all over the world, which we will describe in our next publications as part of the historical excursion about glasses.
