The small degree is the left eye exercises and correction with glasses. For large degrees, surgical correction is recommended, but be cautious.

Discussion on several methods of myopia correction

The eyes are the windows of the soul, and many people have to install glass or glasses on the "windows" due to poor vision. Data show that the myopia rate among Chinese students ranks second in the world, and currently a total of 300 million Chinese people suffer from myopia. In most high schools and universities in China, those who are not myopic are the "others". Wearing glasses is indeed polite, but it also brings a lot of inconvenience, not to mention that high myopia can cause blindness. Therefore, for the sake of health and convenience, finding ways to deal with myopia has become a hot topic among the "glasses people".

1. Conventional spectacle correction method - the simplest and most reliable

Basic situation: The first choice for most people after developing myopia is to wear glasses. In the 1970s and 1980s, glasses were still synonymous with college students and educated people, and were a symbol of elegance. However, as more and more people wear glasses, the public gradually loses their goodwill towards glasses and hopes to take them off one day.

I don’t care whether glasses affect the appearance, but it is definitely inconvenient. After all, a glasses frame with two pieces of glass in front of the eyes will make it difficult to run and jump. If you accidentally encounter an accident, the glasses may be damaged. Damage to glasses and face.

The most concerning question: Will I never be able to take off my glasses after wearing them? Will the prescription of glasses become darker and darker? The price of glasses varies greatly. Is the more expensive the better?

Comment: Glasses often cause inconvenience to the wearer, but it is worthy of recognition that so far, glasses are still the simplest and most reliable way to deal with myopia. As we all know, the characteristic of myopia is that due to the change in corneal refractive power, the light entering the eye does not converge to the retina for imaging, but to the front of the retina, so myopia patients see distant objects blurred. Myopia glasses are actually a concave lens, which can correct the eye's excessive refractive error and focus the object image on the retina. Some people refuse to wear glasses because they are afraid that wearing them will make them myopic. As a result, they increase the burden on their eyes and can only squint to see things around them. The strength of the orbicularis oculi muscle affected by squinting It acts on the eyeball and increases intraocular pressure, which in turn promotes myopia. As for the situation where myopia becomes darker after wearing glasses, in addition to poor eye habits, it may also be related to wearing high-precision glasses. Therefore, when wearing glasses for myopia patients, they must obtain accurate prescriptions through regular optometry, which cannot be deep or shallow, otherwise the purpose of correcting vision cannot be achieved. As for the quality of glasses, it is not directly proportional to the price. Some people in the glasses industry said that the quality of glasses mainly depends on the lenses, while the price mainly depends on the frames. When choosing glasses, pay attention to whether the surface of the lens is smooth and clean, whether there are scratches, streaks, bubbles and particles, and whether the color, texture and transparency of the lens are uniform. When you hold the lens 25 centimeters in front of your eyes and observe distant scenery, if the scenery is clear and not deformed, and the scenery does not jump when moving slowly up, down, left, and right, it means that the transparency and light uniformity of the lens are good. If you can see the scene jumping or deforming, it means there is a quality problem. The frames should be strong, symmetrical, balanced and comfortable to wear.

2. Contact lens correction method - the best vision correction tool for beauty lovers

Removing glasses used to be the dream of many "glasses people", and the emergence of contact lenses has definitely To a certain extent, it helps the beauty-loving "glasses people" realize this dream. However, optometry experts believe that not everyone is suitable for wearing contact lenses, and even some people who are considered suitable for wearing them may experience discomfort after wearing them for a period of time. In recent years, some quality issues related to contact lenses have caused many people to have doubts about them. On the other hand, the prices of contact lens brands on the market vary widely, which sometimes makes consumers confused.

The most concerning question: How safe are contact lenses? Who is suitable for wearing contact lenses? Are there any special considerations for wearing contact lenses?

Discussion: Contact lenses are also called contact lenses, which have high requirements on material production technology and health and safety of wearing. In terms of wearers, contact lens wearers should rule out any of the above conditions such as dry eye syndrome, diabetes, epilepsy, allergies, etc., and they should not be keratitis or trachoma patients. Under the premise that wearing contact lenses is allowed, the biggest problem with long-term wearing of contact lenses is that it can easily cause corneal infection and hypoxia. The cornea of ??the human eye, which is a layer of material on the surface of the eye like a windshield, can be infected by germs like most parts of the human body. Contact lenses, as foreign objects that are close to the surface of the cornea, require special attention to hygiene and frequent cleaning and replacement; another On the other hand, the cornea also needs to breathe oxygen, and oxygen must be dissolved in tears before it can be absorbed by the cornea. After wearing contact lenses, the cornea will have difficulty breathing just like wearing a mask. Over time, hypoxia will occur. At this time, the contact lenses need to be removed to allow the eyes to rest and breathe. Although some companies claim that the contact lenses they produce are 100% breathable, this is often just a gimmick, because no matter how good the breathability is, contact lenses cannot and always fully meet the eye's need for oxygen.

Therefore, the correct way to use contact lenses is that they must be used alternately with ordinary glasses regularly, especially to avoid wearing them for a long time

3. Myopia treatment equipment - don’t expect too high

< p>For myopia in children and adolescents, a wide variety of health care appliances, traditional Chinese medicine therapies, eye massages, myopia treatment devices, etc. have appeared on the market. Many parents feel that no matter how much they can save their children's myopia, it is good. However, many parents reported that after buying myopia treatment equipment such as eye masks and massagers, they found that the help for their children was not obvious.

The question of greatest concern: Are myopia treatment devices effective? How to choose?

Discussion: For myopia, the currently recognized correction methods in the medical community are glasses and surgery. As for physical therapy, drugs, instruments, etc., children with pseudomyopia can be tried appropriately, but they are not 100% effective. Current medical research shows that the process of myopia is basically irreversible, so there is no treatment device that can cure myopia. However, for some pseudomyopia that occurs in teenagers who are in the growth and development stage, many instruments can be tried as conditions permit. The so-called pseudomyopia means that due to reading at close range and working for a long time, the ciliary muscles are often in a state of high tension. The excessive adjustment function causes ciliary muscle spasm, which causes temporary vision loss. However, after resting or using ciliary muscles, Vision may improve or return after administration of myoplegic agents. The degree of myopia is not the criterion for judging true or false myopia. Children may have false myopia at 200 degrees, and adults may have true myopia at 100 degrees. When you go to the hospital and use cycloplegic agent (mydriasis), you can distinguish true and false myopia, and you can also determine the degree of myopia. In addition to various instruments and medications, methods such as paying attention to eye usage habits and looking far away can also help return to normal.

4. Excimer laser surgery is called Zhengfa - the most advanced and mature myopia treatment technology in modern times

More and more people around us go to the hospital to have myopia laser surgery and watch the removal of myopia. Even though they have lost their glasses, their relaxed and confident demeanor can’t help but make people envious. Myopia patients who have undergone excimer laser surgery have mixed reviews. Some people think it is very suitable, and some people find it uncomfortable. There are often "conspiracy theories" about myopia surgery. In addition, there are many types of myopia laser surgeries, such as PRK, LASIK, LASEK, etc. Some are very expensive and some are relatively cheap, so it is generally difficult for ordinary people to judge which one is safe or cost-effective.

The most concerning question: Is excimer laser surgery safe for treating myopia? How effective is it? Are there any side effects? Which hospital is better? Why do some doctors who treat myopia prefer to wear glasses instead of surgery?

Discussion: Currently on the market, PRK surgery has been basically eliminated due to its own shortcomings. LASIK and LASEK are more commonly used. The former is "in situ keratomileusis" and the latter is "subepithelial keratomileusis." Inlay technique". However, the basic mechanism of the above operations is the same, that is, it is completed by cutting the cornea of ??a certain thickness. Therefore, the higher the myopia, the more the cornea is cut, and the lower the safety of the surgery.

Some myopic patients have very thin corneas and cannot undergo laser surgery for myopia. Others with glaucoma, fundus diseases, and potential keratoconus cannot undergo surgery. Generally speaking, myopia laser surgery is now quite mature in our country, and the success of the surgery mainly depends on the equipment for laser surgery and the skills of the specific surgeon. Therefore, while inquiring about whether the price is appropriate, it is best to find out about the equipment of the unit where the surgery is performed, the experience of the doctor, etc. Generally speaking, it is relatively safe to go to a large hospital for surgery because the surgical plan and preoperative examinations will be more professional and detailed. A few non-standard clinics may hide test results in order to make a profit, or even perform surgery on patients who are not suitable for surgery, thus greatly increasing the risks of surgery.

Some patients will experience vision regression after surgery. This is often caused by the surgeon's own reasons, such as poor eye habits or other reasons. In fact, it has nothing to do with the surgery and does not mean that the surgery was unsuccessful. .
