Who was nearsighted among the ancient figures?

Among the ancient figures are Su Dongpo, a famous writer in Song Dynasty, Ouyang Xiu, Emperor Kangxi in Qing Dynasty, Yong Zhengdi, Emperor Jiaqing, Emperor Daoguang, Xuan Tong, famous scholars Ji Xiaolan and Ding Peng. All of the above are ancient people with myopia.

Su Dongpo, a writer in the Song Dynasty, was also nearsighted. It is said that when he was studying, he was very close to writing. In order to delay the decline of vision, he developed Qiju tea as a health care product for eyes.

Before the Southern Song Dynasty, short-sighted glasses were not invented. At that time, the ancients were nearsighted and could only rely on some herbs. Both Du Fu and Wang Anshi wrote the poem "Old people see flowers like fog", and they feel that their eyesight is declining after they get old, which may include both myopia and presbyopia.

Lu You's sentence "Teenagers spend their eyesight on reading, but they often go to bed early when they are old" shows us the regret and sorrow of not caring for their eyes when they were young. As far as the shortsightedness of the ancients is concerned, a scholar in the Ming Dynasty wrote a doggerel: "Xiao Jun's eyes are so strange, I stood beside him and asked who it was?" The sun shone marbles through the window lattice, and the moon moved to pick up sticks.

I looked at the painted wall, black and blue, locked the book box and twisted my eyebrows. It's even more ridiculous. Blowing a lamp will burn the skin of your lips. "In the poem, all kinds of jokes about myopia are just around the corner. I don't know who it is. I burn the shadow of flowers under the moon as firewood, watch murals and hurt my nose, lock my eyebrows in a book box and blow a lamp to burn my lips.

Myopia in the Qing dynasty also made many jokes. Erqi, Minister of Qianlong Dynasty, was the half-brother of E Ertai, Minister of Military Affairs. He was smart and eager to learn since he was a child, and he read quickly. Unfortunately, his eyesight was poor and his eyes were highly myopic. Xiao Ting Miscellanies records that one day, E Ertai was soaking his feet at home, and his younger brother Erqi hurried to talk to him.

E Ertai had no time to keep out, so he sat cross-legged with his feet in his arms. Erqi hit E Ertai's foot with a cigarette pan. E Ertai looked at his brother in horror, wondering what he meant.

Erqi said, "What does the big white cat need, and what is the meaning of brother Bao to him?" What's so rare about a white cat that my brother still holds it in his arms as a treasure? E Ertai was fat in vain, and his fat feet were regarded as white cats by his younger brother Erqi, which shows that Erqi's myopia is quite serious. This incident was spread in the circle of friends as a paragraph by the courtiers, and it became a joke for a while.
