look at the people around you. Almost 7 or 8 of 10 people are wearing glasses. So many people around the world are myopia. Is myopia really so difficult to treat? As long as you start myopia, you can only wear glasses in your life?
indeed, myopia is becoming a big problem now. Research shows that there are 1.6 billion myopia patients in the world by 2004, and the number of myopia may increase to 2.5 billion by 2020. The prevalence of myopia in Southeast Asia has been as high as 80%, and the situation in China may be more serious.
why does myopia seem to suddenly get out of control?
in fact, there is no final conclusion about this. After all, the causes of myopia are very complex and are affected by many factors, including genetic and environmental factors.
many studies have confirmed the role of genes in the occurrence of myopia. Children with parents’ myopia are much more likely to develop myopia than children without parents’ myopia; If both parents are highly myopic, the child will basically be myopic.
the worse news is that if parents are not myopic, it does not mean that children will not be myopic. Because environmental factors still play a great role. The improvement of education level, urbanization and the increase of close work will increase the possibility of myopia. There are so many myopic people now, which may have a great relationship with the modern lifestyle.
is there any way to control the development of myopia?
and
in fact, the best way is to do a good job in prevention and try not to make children myopia.
and
children are born with relatively small eyeballs and are in a state of hyperopia. With the growth of age, the eyeball continues to develop, showing a process from hyperopia to emmetropia, and then myopia may occur. Therefore, in the process of emmetropia, it is best to establish an eye refractive file to record the degree of children every year in detail. Once there is a sign of myopia, intervene as soon as possible. The intervention methods of
and
mainly start from environmental factors. After all, genes are difficult to change. The most important method of
and
is actually very simple, that is, to increase children’s outdoor time. It’s actually easy to operate. For example, during recess activities, children can stay outside the classroom, and parents can take their children outdoors on weekends.
and
are to exercise children’s eye adjustment ability. For example, encourage children to participate in table tennis and other sports. When playing table tennis, children’s eyes keep looking close and far, and their adjustment ability is exercised during sports.
and
can also take children to fly kites, climb mountains, etc. the principle is to let the eyes look at the distance more; Play less electronics and look closer.
what if you are short-sighted and don’t want to wear glasses?
myopia is corrected by wearing glasses (frame glasses and contact lenses).
frame glasses: the most widely used, safe and effective correction method at present, but for active children, it is not convenient to exercise. Some children are also due to psychological factors (afraid of being ridiculed and feeling ugly) they are resistant to frame glasses.
contact lenses: they can directly contact the cornea and have good visual effect, but they have certain requirements for the daily care of the wearer. Improper care may lead to inflammation, and some people can’t wear them because they can’t adapt. They are not suitable for young children.
However, out of the pursuit of convenience and appearance, some people find it difficult to accept wearing frame glasses or contact lenses for a long time. There are two options for this group of people.
myopia laser surgery: the operation time is short and the postoperative visual effect is good. It is a widely recognized means of lens removal. Especially in recent years, with the emergence of “all femtosecond” technology, the incision is only 2mm and there is no need to make corneal flap, which ensures the natural shape of cornea, and the postoperative effect is better than ordinary laser surgery.
but not everyone can do myopia laser hand, which needs to pass strict preoperative examination. Teenagers must be 18 years old and have stable diopter before surgery.
corneal shaping lens (OK lens): corneal shaping lens is a special type of contact lens. It is a rigid breathable contact lens with inverse geometric design opposite to the surface of human cornea. Wearing it on the eye surface can shape the cornea, reduce myopia and significantly improve naked vision. Although it is also a contact lens, it only needs to be worn during sleep and not during the day.
ThisThese kinds of lenses are usually worn for 6-8 hours when sleeping at night. After removing the lenses in the morning, the following effects can be achieved:
(1) it can effectively curb the rapid deepening of myopia for children and adolescents.
(2) after patients wear them for 6-8 hours every day, their eyes are in a state of non myopia or reduced myopia in the rest of the time without wearing any glasses, You can have clear naked vision.
(3) corneal shaping lenses are mostly worn at night, which can effectively avoid external pollution and impact. There is no need to wear glasses during the day, which improves the comfort.
and
but corneal shaping lenses are not suitable for everyone. They need to pass strict inspection and try on. In daily use, parents also need to spend more time and energy on the use and cleaning of children’s lenses.
