Myopia prevention and control: Don't let your child embark on the "road of no return" of myopia
Most people will have pseudomyopia before myopia, but due to insufficient science, when people find myopia, they do not consciously check whether it is really myopia, whether there will be pseudo-myopia, so that they miss this good period of vision correction treatment, which is deplorable!
Myopia does not appear overnight, and the process from pseudo-myopia to true myopia eventually develops into high myopia is slow. Early detection and early intervention are the key to preventing myopia. Most children's myopia can be avoided, but it is dragged out by parents.
Pseudomyopia stage
Pseudomyopia, in essence, is not myopia, may be orthopic, may be mild hyperopia, but many times the symptoms are very similar to myopia.
Usually the eye axis of pseudomyopia does not grow, but the focus falls on the front of the retina, resulting in unclear vision and needs to be adjusted.
This type of myopia is mainly caused by the tension of adjustment, so the myopia disappears after the adjustment is relaxed.
Therefore, although pseudomyopia will lose vision for a period of time, it can be restored to a certain extent through appropriate rest or targeted correction and prevention. Timely detection, related treatment, then this is a good period to restore vision, will not develop real myopia.
If it is not well prevented and treated at this time, the retina stimulates the continuous development of the sclera, causing the growth of the eye axis and gradually developing true myopia. Generally, children in the stage of pseudomyopia, if parents can find and deal with it in time, they can control it in time! And false myopia to true myopia is often 1 to 3 months, many parents think that they can be dragged to the winter and summer vacations to check again, but unfortunately dragged into true myopia!
The authenticity is regarded as an organic change, caused by the extension of the eye axis, and there is no obvious relationship with the adjustment.
True myopia stage
If pseudomyopia is not alleviated in time, it will eventually lead to the lengthening of the eye axis and become true myopia.
The eye axis of patients with true myopia increased significantly compared with the normal average, and the degree of myopia increased by 300 degrees for every 1 mm increase in the eye axis in myopic patients. In particular, the development of myopia in young children deepens rapidly with the development of the body, and most children grow at an average rate of 75 to 150 degrees per year until the age of 18! There is an annual growth rate of up to 200 degrees!
Stages of high myopia
Adolescent myopia patients continue to expand as the eye axis increases, and it can be seen in the eyeball specimen that it is much larger than the normal eyeball. In the process of enlarging the eyeball, the sclera and choroid can grow according to the signal requirements inside the eye, but the retina can not grow with it, and the retina will appear many cracks or lattice degeneration in the peripheral part of the retina in order to attach to the enlarged sclera and choroid, causing pre-lesions for future retinal detachment.
Many parents react that their children "can't see the blackboard clearly", and only then do they begin to pay attention to their children's vision. However, when the child can't even see the blackboard clearly, he basically has to wear glasses of about 200 degrees, and some children have myopia degrees of up to more than 500 degrees...
When the child has just developed pseudomyopia, timely treatment can be quickly restored, and once myopia is formed, it is a flood beast, at this time it is necessary to control the growth of the child's myopia through professional intervention.
