myopia needs to be intervened and improved. At present, there are many methods for the treatment of myopia. Now, the main methods of wearing glasses on the market are myopia prevention and control glasses and progressive multifocal glasses. Here, parents and friends should pay attention to the fact that the wrong choice may cause invisible harm to your child.
from the perspective of lens principle, myopia prevention and control lenses include: low degree convex lens and prism.
can prevent the occurrence and development of myopia by wearing low convex lenses. However, because of long-term use of convex lenses, it is generally not advisable to adjust and relax, and the degree of binocular distribution can not be well coordinated with the near objects. The principle of
prism is to transform near vision into far vision. After long-term use, the function of eyes spreading is excessive, which can not be well coordinated with the increase of eye adjustment when looking at nearby objects. It is easy to appear visual fatigue, diplopia and intermittent strabismus in daily life and work, so it is also undesirable.
are common progressive multifocal lenses in the market in recent years. Do you know its principle? Its principle is to reduce adjustment to control the rapid development of myopia, It is suitable for children with implicit skew or strong adjustment (about 7 ~ 10% of the myopia population).
what about the children who account for about 90% of the myopia population and are not suitable for wearing such lenses? (that is, the vast majority of the myopia population are children with implicit skew or insufficient adjustment. “
The merchant is not a hospital and will not give professional explanations. The parents don’t understand it. Many times, the store staff say “scared” by a professional word!
the promotion of progressive multifocal lens in the market for the treatment of myopia is very strong. Please pay attention to it. Make sure whether the cause of your child’s myopia is consistent with the adjustment principle of this product. If it does not belong to the suitable population, never, never match progressive multifocal lens!!!
the vast majority of children with myopia have insufficient eye regulation, and then relax the regulation treatment, which is even worse! It is equivalent to a 10-year-old child who is too lazy to walk. If you give him a crutch and an electric wheelchair, the child may never walk independently.
children with exophoria or insufficient adjustment wear progressive multifocal lenses, which will not only aggravate the child’s exophoria, It is also possible to advance your child’s performance age of near fatigue or presbyopia in the future (eye adjustment function declines rapidly). However, if your child has implicit skew or strong adjustment, progressive multifocal lenses are suitable for your child.
add light down when using progressive multifocal lenses (add) how much to give is very learned. You must find a professional to give the prescription after comprehensive examination.
We encountered a typical example. The child has been wearing convex lenses to prevent myopia since he was 5 or 6 years old. Later, when he was nearsighted, he wore progressive multifocal lenses. After examination at the age of 15, the child had exophoria and insufficient adjustment. At this time, trouble came. After correction, the child’s far vision reached 1.0 respectively, but the near vision was 0.3. If the near vision reached 1.0 for both eyes, the far vision would reach 0.4 respectively.
are too young to see clearly? The child has presbyopia in his eyes.
this article aims to warn parents and friends that they should be careful when using glasses to solve the problem of myopia. It is suggested to carry out a comprehensive test of visual function and wear them reasonably. Once again, remind parents and friends that while paying attention to children’s vision problems, they must understand them clearly, and then choose appropriate, effective and safe solutions for their children. They can’t be blind.
