Usually there are pairs in my wallet, car and trunk coat.
In fact, I am proud and ashamed to admit that I do wear "indoor, winter and night" sunglasses, as ed sheeran eloquently said in his recent song "Newcomer".
Although this line sounds impractical, the tradition of using sunglasses has long gone beyond what is currently considered normal.
The origin of sunglasses goes beyond simple ultraviolet protection and style.
In the past, colored lenses were also used to hide, enlarge and correct.
Sunglasses began to become a necessity for Inuit people living in the far north.
Perhaps because of the reflective nature of snow (white), sunlight is very strong for Inuit people.
However, their sunglasses version is not designed like this now.
Inuit carved sunglasses from walrus ivory instead of large colored lenses.
They are round and connected by the bridge of the nose.
Ivory blocks almost all the light, blocking the sunshine of their eyes, except those that slip out of the slender cracks.
The intensity is not affected, but the amount of direct exposure to the sun is definitely reduced.
In China in the13rd century, sunglasses were the main articles for the court.
During the trial as a judge, sunglasses made of "smoke should be timely" are used to prevent both the prosecution and the defense from reading the judge's expression.
This may provide a better sense of justice, because the argument will not be changed or affected by accidental facial reactions.
On the other side of the world, modern Venetian glass blowers are believed to have made hand-held magnifying glasses or monocles (sometimes called "reading stones") to help those who have visual difficulties in reading. A single crystal gallery full of gold in the 20th century.
In early modern times (by SA 3.
0), people explore the use of color and darkness to help the visually impaired.
Although glasses using prisms have been used to correct vision in practice, the first signs of color and color correction appeared in about18th century.
A man named James Ayscough tried to correct some damage with blue or green glass.
However, Ayscough's job was to invent scientific instruments-his mentor invented the first microscope.
The relationship between microscope and prescription lens is quite obvious (both allow the enlargement of words and images), so the leap from Escov's lens to colored lens is actually not a leap at all.
His suggestion for colored lenses is a corrective plan, perhaps to combat color blindness or depth perception.
Anyway, Escoug's glasses are the predecessors of "cool" sunglasses promoted by Life magazine in the 1930s, with blue lenses and metal wire frames.
As a fashion dimmer in a strict sense, sunglasses did not appear until the 20th century. It is based on previous work, such as Esco, and combined with new optical technology.
The widespread release of sunglasses is attributed to Sam Foster: movie stars appreciate the way lenses protect their eyes from the spotlight of movie scenes, and later appreciate how glasses hide their eyes from paparazzi.
Of course, once celebrities start wearing products in public, the public will flock to accept this tradition.
Soon, colored lenses were called "cool" and "mysterious" by the market.
This is an advertisement for Foster Grant to mass-produce fashionable sunglasses.
The military's adoption of pilot glasses will only further enhance the reputation of sunglasses fashion.
The name Ray-Ban is widely known in the sunglasses circle. He designed an anti-glare pilot at 1936, using the same technology as the new Polaroid camera.
The main tool for Polaroid to inadvertently promote the cause of sunglasses is that sunglasses companies borrowed their polarized lenses to provide anti-glare technology to ensure that sunlight is filtered and eye injuries are prevented.
By 1938, Life magazine began to report the "new fashion" of sunglasses, Neversky, Ray-Ban's flying boy.
Just a glance at a crowded beach or outdoor shopping center will reveal that this fashion has never faded, but has become more and more popular and diversified.
Nowadays, sunglasses can be used not only to block sunlight, but also to correct vision, which is a great progress compared with Eskov's attempt to correct vision with color.
In many ways, prescription sunglasses are the actual origin of glasses and the climax of color correction. Of course, they eventually developed into celebrity high fashion.
However, although some people think that counter glasses are still an unnecessary fashion, it should not be forgotten that they have developed from hundreds of years of innovative efforts.
Their use, color tone and correction ability may develop over time, but the protective effect of sunglasses is still very strong.
