According to the data, glasses first appeared in Florence, Italy in 1289. It is said that the most important tool in the world was invented by an optician named Amato and an Italian named Spina who lived in Pisa. But some people think that China people invented glasses 2000 years ago. Although it is still a mystery who invented glasses first, it is an indisputable fact that glasses appeared in China in the middle of the Ming Dynasty. In the second volume of "Stay in Youth Day" in the Wanli period of the Ming Dynasty, Heng wrote: "Every time you read an article, your eyes are tired and you don't know its details, so you can hide your eyes, keep your spirit, and write clearly. It was tied to the back of the head with silk, and no one knew, so I asked more questions. Yu Yu said, "That's right. "This is the original name of" grandma ". There are not many images and physical materials of China's early glasses. In the Ming Dynasty oil painting "Du Nan Fan Hui Feng Guang" in China History Museum, there is an old man with glasses. During the Qianlong period of the Qing Dynasty, China was able to produce glasses. The frame is a black lacquered wooden frame with ribbons tied on it, and the lenses are made of crystal. During Jiaqing period of Qing Dynasty, glasses became popular. Zhang said in Xu Du Men Zhu Zhi Ci: "Anyone who is nearsighted wears glasses, and the shades in the shop are distinct. It is more tolerant to raise your eyes, and it is wise to fight for it. "Interestingly, the depth scale of glasses in the Qing Dynasty is divided according to the twelve branches of Zi Chou Yin Mao, which is recorded in Xiang Yan Jieyi by Li Guangting, a historian of the Qing Dynasty. Since human beings invented lenses in the13rd century, they have been polishing lenses with crystal glass. 1937, France invented a plastic spectacle lens called acrylic, which is not fragile, but has poor clarity. 1954, an engineer from the Izuru company in France was inspired by the materials used to make the cockpit of an airplane, and thus invented the resin lens. Since then, this kind of lens has become the supreme lens kingdom in the world, and it is still in use today. It is best to collect glasses with intact lenses, frames and mirror boxes (in a sense, frames and mirror boxes are the value of glasses collection). Like all collections, the older the glasses, the higher their value, but collectors don't have to "like the new and hate the old". With the development of modern high technology and the improvement of people's living standards, glasses are no longer just daily necessities for correcting eyesight, but gradually become facial beauty decorations. It is this subtle change that has spawned a number of glasses with novel styles and unique functions, such as: anti-fog mirrors that can see clearly when taking a bath in the bathroom or when the temperature difference between indoor and outdoor changes; A computer mirror that can reduce the damage to people's eyes caused by long-term use of computers and screen rays; A lens has multiple layers and different bald heads, which can be used to watch movies or walk, watch TV, computer or read newspapers (also called multifocal lens); The fishing mirror specially used for fishing can not only subtract the light intensity of sunlight on the water surface through refraction, but also clearly see the movement of the water surface; Night vision goggles for driving at night can not only soften the headlights of oncoming vehicles, but also clearly see the road and ensure safety ... These glasses not only bring great convenience to citizens' lives, but also add new varieties to the glasses family, which are favored by glasses collectors. I know a Tibetan friend. Although he doesn't wear "glasses", he has a special liking for glasses collection and has a unique vision. Regardless of ancient and modern glasses, he will not let go easily. In a few years, he collected nearly 300 pairs of glasses of Ming, Qing and Republic of China styles. There are gold, silver, gold, white copper, brass, phosphor copper, wood, tortoise shell, ox horn, plastic and other 10 kinds of frames, and the mirror boxes are also varied and colorful. Asked why he gained so much, he hit the nail on the head: the less people are interested, the more they can find what they love. It seems that the way of collection really needs to find new ways to "fix" the positive results. This is the case with glasses series, and so are other series.
