This kind of eye drops can paralyze the ciliary muscle, relieve its spasm, relax its regulation, and make the lens thinner by suspending ligaments. Therefore, this kind of eye drops can treat pseudomyopia. However, this kind of eye drops has a characteristic, that is, the eye drops with strong efficacy have strong side effects. Atropine is one of the most effective eye drops, but its side effects are also the strongest.
Experts believe that this kind of eye drops cannot be used for a long time. Experiments show that long-term injection of atropine solution into animals' eyes can make animals' eye axis longer, ciliary body contract and sclera thinner, leading to myopia.

What is the effect of Chinese medicine in treating myopia?
Traditional Chinese medicine emphasizes syndrome differentiation, that is, according to the different symptoms of different patients, the right medicine and specific treatment are carried out. Some Chinese ophthalmologists use the principle of syndrome differentiation to classify myopia into the following four categories and treat them differently.
A
Liver and kidney deficiency type should nourish liver and kidney;
B
Spleen and stomach deficiency and cold type should strengthen spleen and stomach; C
Heart-qi deficiency type, it is appropriate to replenish the heart and soothe the nerves; D
Deficiency of qi and blood should replenish qi and blood.
These Chinese ophthalmologists usually make basic prescriptions for myopia according to these four types. In clinical use, drugs should be added and subtracted according to different conditions of each person.
These traditional Chinese medicines can regulate viscera and act on eyes through meridians, so they have the effect of improving eyesight.
There are also many Chinese patent medicines on the market to prevent access. They are made according to the induced causes of myopia, and there are many types such as oral liquid, tablets and pills. Most of the ingredients in these drugs are codonopsis pilosula, Angelica sinensis, Lycium barbarum, Poria cocos, Ophiopogon japonicus and other traditional Chinese medicines. It has the effects of benefiting qi and nourishing blood, nourishing kidney, soothing the liver and improving eyesight.
Because the essence of Chinese medicine is different from person to person, and Chinese patent medicine used for treatment will be the same. So some people use it effectively, and some people use it ineffectively.
In addition, there are Chinese medicine eye drops on the market, which can supplement eye nutrition and improve eye blood circulation, so it also has the effect of improving eyesight.
However, some Chinese medicines claim that they can treat true myopia. So this statement is correct?
In this regard, Chinese medicine experts pointed out that Chinese medicine can regulate the functions of zang-fu organs and the whole body, relieve eye fatigue and improve vision, so it has a therapeutic effect on pseudomyopia. However, true myopia is caused by the lengthening of the axial length. The longer the axial length, the higher the degree of myopia, and all drugs can't shorten the axial length. Therefore, Chinese medicine cannot treat true myopia.
What is the principle of improving eyesight in traditional Chinese medicine?
Chinese medicine believes that the eyes are closely connected with viscera and the whole body through meridians, making the body a unified whole. The eyes can see the world clearly, which is caused by the nourishment of the five internal organs and the essence. Therefore, the eyes are called "windows of the internal organs".
If the viscera function is out of balance, it will cause eye diseases. On the contrary, eye diseases can also cause visceral dysfunction. This is the overall concept emphasized by Chinese medicine in treating eye diseases.
Moreover, among all zang-fu organs, the relationship between the eyes and the liver is the closest, so there is a saying that "the liver opens its eyes" and "the liver can see when receiving blood".
In addition, Chinese medicine usually applies the theory of five rounds to treat myopia. This theory is a classic theory of ophthalmology in traditional Chinese medicine. The five-wheel theory divides the five parts that the eye can see from the outside to the inside. Called cell face and two.
White eyes, black eyes and pupil spirit belong to five chakras and five internal organs respectively.
Traditional Chinese medicine believes that most diseases at chakras are caused by dysfunction of zang-fu organs. Therefore, we can infer the pathological changes of the corresponding viscera by observing the changes of the eye chakra. This is a unique five-round syndrome differentiation in ophthalmology of traditional Chinese medicine (see also the chapter on massage).
