In ancient times, how could myopia live without glasses?

China had glasses in ancient times, and he wore them after Yongzheng. You can go to see his palace paintings. A little earlier, there were glasses in the Sui and Tang Dynasties, but those glasses existed in the form of crystals, and the effect is another story. If you don't wear glasses, you can only squint or can't see clearly at all.

It is said that the glasses in ancient China were oval, set in a frame made of tortoise shell, glued to the temples with copper glasses feet, tied to the ears with strings, or directly fixed on the hats. Moreover, glasses were expensive at that time, so they were regarded as a symbol of status.

In ancient times, many people were physically disabled and determined. What about myopia? Thinking of Zuo Qiuming, he dictated Zuo's Spring and Autumn Annals after he became blind. But it can also prove that there were no glasses in the Spring and Autumn Period.

The so-called tonic, taking medicine and chanting Buddha in medical books are metaphysics and can't be true. Therefore, myopia glasses should be the best coping method for the ancients. Unfortunately, it seems that before the Ming and Qing Dynasties, there was no record of making myopia glasses with lenses.

As for the Ming Dynasty, a large number of glasses (reading glasses and nearsighted glasses) finally appeared in novels and scrolls. Western glasses were born at this time. We have no way of knowing whether the glasses of the Ming Dynasty were imported or made in China. In a word, myopia patients in Ming Dynasty could already use glasses to meet their daily needs.

After all, in ancient times, only a few people could use glasses. Ordinary people are nearsighted when they are nearsighted, and they often squint at people. There were indeed many nearsightedness in ancient times. During the Jin and Yuan Dynasties, Li Dongyuan, a medical expert, analyzed hyperopia and myopia, including "hyperopia but not myopia" and "myopia but not hyperopia".
