What did the ancients do if they were short-sighted?

The production of glasses was originally to correct people's eyesight and protect their eyes. But in the eyes of the Empress Dowager Cixi, the ruler of the late Qing Dynasty, who was closed off from the country, this was a Western lewd trick, and the people around her had to get her permission to wear it. She may not know that Emperor Yongzheng had already worn glasses as early as 200 years ago. Emperor Yongzheng was 45 years old when he ascended to the pole and his eyesight was very poor. In order to improve office productivity, he boldly embraced and used the strange thing of glasses. The glasses worn by Emperor Yongzheng were all specially made by the Ministry of Internal Affairs by order. This is well documented in the archives of the Office. For example, "make a few more pairs of crystal, citrine, ink crystal, and glass glasses, and all of them should be good"; "Make 10 more pairs of glasses according to my use", there are many such orders. According to incomplete statistics, there are as many as 35 pairs of glasses specially made by the office for Emperor Yongzheng. Emperor Yongzheng placed these glasses everywhere, and they were available everywhere. The picture shows the myopic glasses of the Qing Dynasty, and Yongzheng sometimes gave the glasses to the ministers of civil and military affairs. Ji Zengyun, the governor of Jiangnan River, has always had a poor eyesight, so Emperor Yongzheng gave him a pair of glasses, and said: "I use a pair of glasses, I don't know if it can be used for the eyes, if not, there is no need to be exempted, just hand it back, and I will issue another one." Ji Zuo Xie said that it was just "in line with the minister's eyes", "from now on, he will be more aware of the spirit, and he should be especially motivated to do things". Emperor Yongzheng even used glasses for labor protection in craftsmen. Yongzheng once sent a decree to the minister: If the eyes of the person who splashes the ashes are not covered, but they are afraid of being injured, they will make some rewards for the glass bubbling eye patches. In the same month, the manufacturing office made 4 pairs of bubbling glass eye masks and 8 pairs of flat glass eye masks. Emperor Yongzheng read it and instructed: Reward it to the engineering office. The use of glasses for the labor protection of people splashing ashes is really a great creation of Emperor Yongzheng, and it is also rare. Related reading: Eyeglasses and myopia glasses。
