In the previous article, we discussed “Why are Prada sunglasses so expensive?”. In this article, let’s talk about “Why were sunglasses invented?"
When I was watching a live television broadcast of a marathon, a foreign friend in the studio asked, "Why don't they wear sunglasses?" The host explained: in China, sunglasses have not reached the level of popularity of everyone. Indeed, in the eyes of many Chinese, sunglasses seem to be a fashion accessory. Just like in the 1980s, young people used to wear sunglasses without even taking off the tags on them, because they wanted to imitate the celebrities from Hong Kong and Taiwan. It was the fashion icon of the last decade.
Why were sunglasses invented?
In fact, sunglasses were the first functional eyeglasses invented by man. Prehistoric Inuit people used walrus bones to make "special glasses" to block the reflection from the snow. In ancient Rome, nobles held polished gems in front of their eyes to watch gladiators fight to the death. These are "improvisation" of people to block the glare of the sun. In recent years, people have begun to pay attention to the damage of ultraviolet rays to the eyes, but the problem of glare is still poorly understood. A Dazzle is a visual condition in which the contrast of light in the field of vision is so extreme that it makes it visually uncomfortable and reduces the visibility of an object. A sense of brightness in the visual field that the human eye cannot adapt to may cause disgust, discomfort, or even loss of visibility. Glare light is one of the important causes of visual fatigue.
When do you need sunglasses?
It's not just drivers who should wear sunglasses to block out glare, but pedestrians, cyclists, joggers, and so on. Otherwise, the scene at the beginning of the article would not have happened.
Another scenario is when traveling on vacation. Anyone who loves photography knows that if you overexpose a picture, it leaves nothing but a blank space. So, in the face of the sunset, you just say "there's sand everywhere," because the glare of the sun is blocking your view.
For people who want to wear sunglasses but don't want to wear contact lenses, myopic sunglasses are definitely the first choice. It uses lens coloring technology to turn any pair of sunglasses into lenses with a myopia rating. The wearer can choose the style of sunglasses he or she wants and the color of the lenses to show their personality. You can also choose to coat the surface of the lens with a dazzling film so that the color of the lens is more colorful and fashionable. The style is fashionable and beautiful, convenient and practical.
