Brain Vision Science: Why don't foreign countries do mydriasis for myopia?

Why don't foreign countries do mydriasis for myopia? What is the natural healing effect of vision? In recent years, as long as you go to the hospital for optometry, doctors require mydriasis. Many parents will ask doctors, is mydriasis harmful to children's eyes? This is not a waste of time. Since the doctor asked for mydriasis, how can it be said to be harmful? Is it not contradictory? You should know about domestic medical care, so is mydriasis harmful to your eyes? What is mydriasis? Find out what mydriasis is first. Mydriasis is an optometry under the condition that drugs completely paralyze the ciliary muscle of the eye and make it lose its adjustment function. Children had better use slow mydriatic, usually three days before optometry. It will take half a month to recover. Together with the muscles and blood vessels in our iris and eyeball, a part of your body is still for a week. Do you feel pain? The eyeball has two major regulatory functions. The ciliary muscle regulates the lens to see far and near, and the iris regulates the pupil to adapt to strong and weak light to protect the retina, so that these two regulating functions will fail for a week or even a month. Do you think there is any harm? In order to save time and trouble, hospitals generally adopt rapid mydriasis. Because of its fierce efficacy and greater harm, don't believe all the doctors' words. There are too many Chinese medical scams. Is mydriasis useful?

However, hospitals have repeatedly stressed that myopia needs mydriasis optometry. Is it really necessary or is it a way for hospitals to fight against optical shops? Some professionals have consulted a lot about this and come to the conclusion that many foreign countries are not mydriatic about myopia. I asked some people privately, and one of them said that he had asked the most famous optometrist about it. His answer also said that myopia does not need mydriasis, because I didn't ask it myself, and I was afraid of the impact of misinformation, so I can't name names here. In the QQ group, I also asked a former hospital ophthalmology director who now runs an optical shop. He said he was used to mydriasis when he was working in a hospital. "Later, it was gradually discovered that the luminosity after mydriasis was similar to that without mydriasis." Quotes are her exact words. There is also a talk about Wang Qinmei, one of the editors-in-chief of senior technician training materials. He said this: "Wang Qinmei bluntly said that mydriasis is useless", and another netizen directly said that mydriasis optometry was a joke of China. "Give psychological comfort to customers' parents. Once they are dilated, they can rest assured of optometry. "These are just what others say. I want to hear your thoughts. As a colleague who has been engaged in optometry for many years, you are bound to meet some customers who go to the optical shop for optometry and go to the hospital for mydriasis. Such customers give us a chance to compare. What is the result of the comparison? I hope everyone can make a comparison between mydriasis optometry and small pupil optometry in their own work, so that more facts can prove the role of mydriasis and whether mydriasis optometry is necessary or not for myopia. Thinking parents, please don't blindly believe, and are willing to think for themselves, compare or doubt. Worthy of recognition. I hope this article can give some inspiration to parents who often take their children to the hospital for mydriasis examination. So how can we protect our fragile eyes?
