When is the best time to correct hyperopia in children?

We all know that myopia is a disease that is affected by genetic factors. If one of the parents is myopic, the child is very likely to be born with myopia. Of course, children may suffer from myopia due to acquired factors, such as bad living habits. Correspondingly, hyperopia is also an eye disease, and its symptoms are just the opposite of myopia. So when is the best time to correct hyperopia in children?

"Hyperopia" was called "being able to see far but afraid of near" by the ancients. In the view of the ancients, it was caused by insufficient yin essence, excess yang energy, and imbalance between yin and yang. The ancients adopted the method of nourishing yin and tonifying the kidney, and let patients take Liuwei Dihuang Pills according to their symptoms, and the effect would be seen in three months.

Experts say that preschool is a period of eye development for children. Mild hyperopia of 200 degrees is normal, but hyperopia of more than 300 degrees is abnormal and should be corrected to prevent it from developing into amblyopia.

How can parents discover if their children have a tendency to be farsighted? Li Haiyan said that if children aged 3 to 4 years old have "crossed eyes", most of them are caused by farsightedness. In addition, myopia and hyperopia have a common characteristic, which is that people always like to watch TV at a close distance. The difference between the two is that myopia is caused by squinting the eyes, while hyperopia is caused by opening the eyes wide. When these situations occur, you should go to the hospital's ophthalmology department for treatment in time.

Experts suggest that the prevention of "hyperopia" lies in early detection, frequent vision checks, and timely correction and treatment. In addition, people with hyperopia can read more books and do some delicate work that requires close eye work.

How to correct hyperopia

1. Contact lens correction: Wearing contact lenses can avoid some of the troubles and annoyances of wearing glasses, but there are also some problems, such as higher maintenance costs, corneal deformation, corneal hypoxia, corneal infection, eyelid allergies, etc.

2. Glasses correction: Patients with mild hyperopia do not need to use glasses for correction. For more serious adult patients, glasses are required.

3. Refractive surgery: laser photorefractive keratectomy, laser in situ keratomileusis, intraocular contact lens placement, clear lens replacement, etc. Surgery can reduce or eliminate the need for glasses or contact lenses in people with farsightedness.

The principles of mirror fitting are:

(1) Mild hyperopia. That is, preschool children with vision below 300 degrees, normal or near-normal vision, and no symptoms of visual fatigue do not need to wear glasses for the time being. Because many children have physiological hyperopia of 300 degrees. People with symptoms of visual fatigue should wear glasses if wearing them can improve their vision. But it does not have to be fully matched, and 50~100 degrees can be retained.

(2) Moderate to severe hyperopia, that is, more than 300 degrees. Children of this type have varying degrees of decreased vision at both near and far distances, and most of them have symptoms of visual fatigue. Mirrors can be fitted in stages. First wear a pair of hyperopia glasses with a degree slightly lower than that obtained through optometry. After you have adapted, wear a second pair of glasses with a prescription for the full hyperopia degree in proportion to the optometry results.
