Why were ancient literati seldom nearsighted?

At present, the number of myopia patients in China is as high as 600 million, almost half of the total population. The myopia rate of high school students and college students in China has exceeded 70%, and it is increasing year by year. The myopia rate of teenagers ranks first in the world, and the myopia rate of primary school students is close to 40%. In ancient China, few scholars with myopia were found. Why were ancient scholars nearsighted?

Some people say that this is because the ancients suffered from no solution and were afraid of being found and laughed at by others, so they rarely dared to admit that they were nearsighted and could not see clearly. So they concluded that many cultural celebrities in ancient China were actually nearsighted, which can be seen from their works. For example, Li Bai's "There is such bright light at the foot of my bed, is there frost already?" And Lu You's "There is no way to doubt the mountains and rivers, and there is another village in the dark" is an important evidence to prove the myopia of these two brothers: if it is not myopia, how can moonlight be regarded as frost on the ground? You can hardly find your way? Of course, these are just jokes that have not been strictly demonstrated and cannot be taken seriously. As for whether Li Bai's Lu You is really nearsighted, that is a historical issue.
