How does the child myopia do, how should correct?

At present, the safest and most effective way to correct myopia is to wear glasses. Correcting myopia through the optical principle of lenses is the healthiest way to correct myopia in the world. However, we often see that some parents refuse to let their children wear glasses on the grounds that wearing glasses will get deeper and deeper. In fact, this statement is unscientific. If myopia can't be corrected in time and scientifically, it will bring disuse amblyopia and even blindness to children, which will bring great hidden dangers to children. (What about children's myopia? What should I do if my child is nearsighted? The common misconceptions about wearing glasses are as follows: 1. You can't take off your nearsighted glasses. Most people think that myopia can be stopped without glasses, because once you put them on, you can't take them off. This understanding is a lack of optometry knowledge, and it is also extremely wrong. When the human eye is nearsighted, the retina will try its best to approach the focus direction of the object image, and the refractive system of the eye will produce the maximum refractive adjustment, so that the whole refractive system is in the maximum refractive state. At this time, the upper and lower eyelids of the patient's glasses are closed to the minimum state (squinting), the blinking function of the eyelids disappears, and the tears secreted by the eyes cannot moisten and supply oxygen to the cornea through the blinking of the eyelids. The patient's eyes are dry, itchy and watery. Long-term corneal hypoxia, at this time, if viruses or bacteria invade, will form corneal hypoxia, dry eye, keratitis, conjunctivitis. It can be seen that once the eye suffers from myopia, the safest and most effective correction method is to wear glasses and use the optical principle of glasses to form the focus of the object image on the retina. Through correction, the glasses can see clear objects, and the function of the eye refractive system is well utilized, so that the eyes are in a normal refractive state. Therefore, it is unnecessary and unnecessary for patients to worry about whether their eyes can be taken off. According to the definition of optometry, after the parallel light passes through the refractive system of the eye, it forms a focus in front of the retina, making it impossible for the eye to form a clear object like myopia. The human eye has a certain refractive adjustment ability. When the eyes are nearsighted, the eyes will use their maximum refractive adjustment ability to make the image as clear as possible. 2) The diopter of glasses will be deeper and deeper; Many people think that the diopter will get deeper and deeper after wearing glasses, so they refuse to wear glasses.

Accuracy of initial optometry: Patients who undergo initial optometry should go to an eye hospital or a professional optical shop for examination. Teenagers should use mydriasis or fog optometry. The choice of optometrist is very important. At present, the qualification requirements of optometrists in our country are very strict. When choosing an optometrist, you must see whether he has optometry qualifications. People without vision qualification can't engage in optometry. There are many reasons for the deepening of eye diopter, which are mainly related to the following factors: the type of myopia: most of the myopia of teenagers belongs to axial myopia, which is simply that the distance between the front and back of the eyeball is too long. The diopter of axial myopia patients will also change with age and physical development. The accuracy of the first optometry determines the future development of myopia. If the initial optometry is inaccurate, the diopter of glasses is too large or too small, and the corrected vision is scientific and accurate, it will damage the wearer's vision. It is suggested that you choose to wear juvenile myopia control lenses (juvenile progressive multifocal lenses): there are countless additional diopter gradations from far to near on one lens, which can meet the wearer's vision correction needs at different distances, such as far, middle and near. Different refractive correction prescriptions are combined on the same lens, which can reach a certain standard in optical imaging quality and have no characteristic light area appearance. This is called a gradient multifocal lens. Also known as progressive multifocal lenses. Although ordinary monocular myopia lenses can correct myopia, they are more suitable for hyperopia. For young students, close use requires proper eye adjustment, and the human eye will suffer from visual fatigue due to excessive adjustment. The progressive multifocal lens with the latest optical technology uses different optical zones and different optical focuses in the same lens, which changes the adjustment function of the wearer's hyperopia and myopia. When the eyes wearing this kind of lens read or write through the lower optical zone with different optical power from the optical zone on the lens, the adjustment of the lens and ciliary muscle of the eyes will be relieved to the greatest extent, and the fatigue of the eyes when using the eyes at close range will be improved. Effectively relieve the degree of eye fatigue in close proximity.

Because most young students are tired from using their eyes at close range for too long, and with the continuous aggravation of eye fatigue, the degree of myopia gradually deepens and eye fatigue becomes more and more serious.
