Glasses are not rare in modern times, but so far no one has found out who invented them and who put them on first. However, according to textual research, glasses may have appeared in China and Europe at the end of 13. Kyle Poirot once wrote around 1260: "Old people in China wear glasses when reading fine print." In the 0/4th century, it was recorded that a gentleman in China traded a horse for a pair of glasses. Glasses are not as valuable as a horse nowadays.

The ancient glasses in China were actually developed from convex lenses. Generally speaking, lenses are large oval. They are usually made of crystal stone, topaz, seasonal or amethyst, and tortoise shells are made into frames. Some glasses have copper feet on their temples, some have strings attached to their ears, and some have glasses fixed on their hats. Because the tortoise-shell frame symbolizes sacredness and the lenses are also made of precious stones, glasses were very valuable at that time.

Ancient people wore glasses not to see clearly, but to show their noble status. During the Ming and Qing dynasties, glasses made of crystal were the imperial gifts of the emperor, and ministers also wrote letters begging the emperor to give them. Emperor Qianlong read the paper with crystal glasses. Unlike the glasses made of glass sheets now, everyone can buy and wear them. They are no longer noble things, but they can show that they are intellectuals.
