1. A humanistic writer with high myopia reads the corresponding books aloud through extremely short readers to meet his reading needs.
First of all, for ancient literati, they often need to protect their eyesight, because they usually have the need to read a lot of important classical documents and books. However, for some writers with high myopia and severe myopia, they can read the corresponding books with the help of the book boy at home to meet their reading needs. Although this form of information reception will have a certain impact on the thinking of important information to a certain extent; However, we can relatively expand the think tank of our brain, so that the thoughts of ancient writers are gradually refined. Ouyang Xiu, one of the eight masters in Tang and Song Dynasties, is one of them.
Second, rich people in ancient times used medlar to extract oil and light lamps to prevent myopia from deepening further.
For some wealthy families in ancient times, if the main members of the family were nearsighted, they would deliberately use the pre-squeezed wolfberry oil to light the lamp when reading at night. The light lit with Lycium barbarum oil is bright, which does not hurt readers' eyes and can prevent readers from deepening myopia. As early as "Zhi Ya Tang Miscellaneous Notes", it was said that the ignition of Lycium barbarum oil can protect the light. However, in ancient times, Lycium barbarum could not be eaten by ordinary people. After all, it was a precious medicinal material in ancient times, not to mention using Lycium barbarum oil as a fuel for lighting. This service is generally the patent of a big family.
3. Acupuncture at acupoints around eyes is used to treat mild myopia.
Furthermore, ancient Chinese medicine will provide acupuncture services around the eyes for some people with mild myopia. Because the floating needle and scalp needle around the eyes can promote the blood supply and blood supply to the eyes, so that the ciliary muscle of pseudomyopia lens gradually relaxes, and it has a certain recovery effect on pseudomyopia through long-term treatment. However, the therapeutic effect of some true myopia is relatively poor, which only improves the blood circulation of the eyes to a certain extent and achieves the function of soothing the liver and regulating qi. However, it is very difficult to change the current situation of true myopia, mainly to relax and relieve fatigue and prevent myopia from deepening.
Ordinary crystal glasses invented in the late Ming and early Qing dynasties helped people get rid of the troubles caused by myopia.
In addition, in the late Ming and early Qing dynasties, Sun, who was keen on optical research, invented myopia glasses by using ordinary crystals, so that people in the dynasty at that time could solve the problems caused by myopia by wearing myopia glasses in their daily lives. After all, glasses use the optical principle to focus parallel light on the retina, so as to achieve the effect of facing up. Although glasses are made of ordinary crystal, they are relatively easy to reach for people with hard-working family environment because of their limited manufacturing capacity at that time.
Note: The main causes of myopia are excessive use of eyes, unclean eyes, incorrect reading posture and reading in strong light, which leads to corresponding myopia. After myopia, parallel light enters the eyeball and focuses in front of the retina, resulting in a smaller focal length and unclear imaging on the retina, thus affecting the normal life of myopia people. Try to wear glasses after myopia to eliminate the influence on life; If possible, laser surgery can be considered, but it is necessary to fully combine the usual eye intensity to analyze whether to restore myopia through laser surgery. After all, no matter how nearsighted you are, you can't use laser, and the effect of wearing optical glasses will become very poor.
