Zhou Wenwang 1.
According to Records of the Historian, Confucius, with a dream of music, studied piano from Xiangzi and music from Zhou Wenwang. Halfway through the study, Confucius said that he admired Zhou Wenwang very much: "... eyes are like sheep, like the Four Kingdoms, and no one can do it!"
There is a saying here that "eyes are like looking at a sheep". Later, there was a book called Ming Shi, which explained that looking at a sheep means "looking at the vast distance", which means that you can't see clearly from a distance. Now it seems to us that it is myopia.
2. Ouyang Xiu.
Ouyang Xiu, one of the eight masters in Tang and Song Dynasties, was also nearsighted and highly nearsighted.
Ye Mengde in the Southern Song Dynasty recorded in Shi Lin Yan Hua that it was inconvenient for Ouyang Xiu, a great writer, to study after myopia, so he asked his attendants to read it to him directly.
3. Yongzheng.
Yong Zhengdi in Qing Dynasty was not only nearsighted, but also a glasses fanatic.
Myopia:
Myopia is a kind of ametropia. When the eyes are relaxed, parallel light enters the eyes and focuses in front of the retina, resulting in the inability to form a clear image on the retina, which is called myopia. At this time, checking the optometry will prompt the degree of myopia. For example, it is usually called myopia 50 degrees and recorded as "-0.50D".
When the eyes relax, the parallel light from the outside enters the eyes, and its focus just falls on the retina, forming a clear image, which is called face up; If the focus cannot fall on the retina, it is called ametropia.
