nowadays, there are more and more children with myopia, and the degree of myopia of many children continues to grow. Faced with this situation, many parents are very anxious. So, is there any way to slow down the pace of children’s myopia?
first of all, let’s understand the possible factors of myopia, and then analyze the principle of corneal plastic lens to control myopia; Whether the corneal plastic lens can delay the progress of astigmatism; Why should corneal plastic lens be worn at night?
1. What causes the early age of myopia?
myopia is a complex ophthalmic disease. The cause of the disease is not completely clear. At present, it is considered that it may be related to the following factors:
first, more close eye use. Everyone now attaches great importance to education. Many children carry out intellectual development at an early stage and start learning to draw, read and play the piano very early. Using their eyes closely for a long time may trigger myopia.
second, use more electronic products. Many children are playing mobile phones, iPads, computers and watching TV. Using electronic products for a long time may induce myopia. Although many parents have realized this, there is no effective intervention.
third, there are few outdoor activities. When we were children, we were all a group of children playing outside. Now children like to stay at home alone, rarely enjoy the outdoor sun, and our vision is not open.
fourth, myopia is also related to heredity. For example, parents or grandparents have high myopia, and families carry relevant genes, which is also considered to be an important reason for myopia. It will lead children to become myopia at a low age, and myopia enters the exhibition very quickly.
2. Is myopia a modern disease?
the ancients realized the existence of myopia for a long time, and some people began to wear glasses in the Qing Dynasty.
and
are only now. Myopia is appearing earlier and higher, and the incidence rate of high myopia is increasing.
,
and parents attach great importance to it. They will take children to the hospital for examination very early, so the detection rate of myopia has also increased.
and
are of course a trend in the myopia incidence rate and the younger age. The prevalence of myopia is increasing year by year, not only in China, but also in the United States and some European countries. Among the
and
areas, the incidence rate of myopia is the highest in Asia. The incidence of myopia is increasing rapidly every year, and the incidence rate of high myopia is also rising.
3. What are the methods to prevent or delay the development of myopia? The intervention methods of
and
myopia are mainly divided into three parts:
and
are some optical means we are talking about now: for example, the corneal shaping mirror to be talked about today is popularly called OK mirror; There are also soft multifocal contact lenses, which can also control myopia; In addition, the multifocal lens we talked about is called progressive multifocal lens. It is a kind of frame glasses. It also has a certain myopia control effect on some implicit inclined children.
and
are the most popular ones in our Chinese mainland. The OK is the orthokeratology mirror. The second part of
and
is to increase outdoor sports, get more sun and relax your eyes. Research shows that it can prevent myopia. The third piece of
and
is low concentration atropine. It is a kind of eye drops. The hospital uses atropine to dilate the pupils. After eye tapping, the pupils dilate and the ciliary muscle is paralyzed. Atropine with a concentration of 1% has been proved to have myopia control effect, but it is rarely used because it has some adverse side effects and obvious degree rebound after drug withdrawal.
but the latest research shows that 0.01% low concentration atropine brings little side effects and has an obvious effect on myopia control.
