In fact, exophthalmos is not caused by wearing glasses for a long time, but by high myopia. Many people believe that wearing glasses for a long time will lead to sunken eye sockets and prominent eyeballs, which is very ugly. Available glasses experts say: In fact, wearing rimmed glasses for a long time will not lead to exophthalmos. To put it another way, exophthalmos is actually not because of wearing rimmed glasses for a long time, but because of high myopia.
The eyeball is deformed because the visual axis is elongated and the visual width is prominent after myopia deepens. This is the problem of the eyes themselves, not wearing glasses. If the eye is compared to an optical instrument, the distance from the outermost cornea of the eyeball to the innermost retina of the eyeball can be regarded as a central axis of the optical system, that is, the eye axis. The normal eye axis is about 24 mm Generally speaking, the myopia degree increases by 300 degrees with the increase of axis length1mm.
In fact, wearing glasses itself will not cause eye deformation. The real cause of deformation is that myopia deepens and the axial length becomes longer after improper eye protection. Children can't see the blackboard clearly in class, so they must have optometry and glasses. Not wearing glasses will deepen myopia and be harmful to children. Clinical research shows that children who regularly mydriatic optometry and wear appropriate glasses every year have the slowest development rate of myopia compared with children who never optometry and wear glasses, or children who have irregular optometry and wear inappropriate glasses.
The following plastic surgery methods can easily solve the problem of exophthalmos.
Exophthalmos is a common disease of all myopia patients. Although some people can't see exophthalmos on the surface, they actually protrude inward. Because the increase of axial length is the main cause of myopia. So how to solve the problem of eyeball protrusion in myopia?
First, myopia can prevent exophthalmos: because the eyeball of teenagers is still in the development stage, accommodative myopia can easily develop into axial myopia. Especially in high myopia, the anterior and posterior diameter of eyeball is obviously prolonged, and the appearance is exophthalmos. If myopia is corrected normally from the beginning, this situation will be alleviated or even avoided.
Second, wear hard contact lenses: it can prevent re-protrusion.
Third, laser treatment: by finely cutting the cornea and changing its curvature, exophthalmos can be improved theoretically, but because the cutting amount is very small, only tens or hundreds of microns, it has no effect on the appearance of the eyes. This kind of operation is best done after the child 18 years old.
