Today, the family consulted me and the child had already worn 100-degree myopia glasses. As shown in the figure below:
myopia begins with the decrease in the regulation force of ciliary muscle and crystals. The function of looking far and near is that the two ciliary muscles of the eyeball pull the lens to automatically adjust the angle of light entering through contraction and relaxation to ensure the clarity of the scene projecting into the eyes.
However, if you use the eyes for a long time, the ciliary muscles continue to contract and cause spasms, which will lead to obstacles to relax when looking far and not being able to see the distance clearly. In the picture above, there has been spasm and the regulation force is decreasing. If it continues, it is inevitable that the degree will deepen and the eye axis will be lengthened.
It can be said that children and parents have discovered this problem, which is a great progress, and many people still do not realize it.
The primary task of preventing and controlling myopia is to prevent spasms and fatigue from occurring when using the eyes close to the eyes. The eye axis retraction training lens not only pushes away from a long distance to keep the ciliary muscles loose, but also has the effect of exercising the ciliary muscles and crystal adjustment force. It can be worn when using any close to the eyes. Use a computer to read, write, take online classes, and work for adults. The eyes are easy, comfortable and bright. Preventing and controlling myopia is so simple. There are two types: frame type and clip type, see the figure below:
