It is well known that myopia is caused by an elongated axis of the eye.But few people know, and height is same, the person’s eye axis is not born fixed, however as the age grows, grow slowly development becomes longer, after becoming adult generally basically stable.Everyone is born farsighted, with a smaller wheelbase than normal.With the continuous development of the eyeball, the ocular axis will gradually become longer, and the farsightedness is gradually corrected, until the development of emmetropia at the age of 7 ~ 10.But when it comes to adolescence, if the body develops too fast, such as the height grows too fast, it will likely lead to further elongation of the eye axis (under normal circumstances, every 10cm height, the eye axis will increase 1mm), which will lead to the child in the scientific use of eyes, healthy use of eyes, still become myopia.So how long is the eye axis best?Here, Xiaodo provides you with a table of the average development of children’s eye axis in different age stages, parents and friends can carefully compare.Some parents may ask, it’s no use having a watch, how do we know how long a child’s eye axis is?In fact, this problem is very good to solve, as long as the eye hospital or clinic on a regular check, and establish a child refractive development file on the line.Refractive development archives are like the growth and development archives of the eye, which record all important parameters of the eye, such as vision, diopter (myopia, farsightedness and divergence >, corneal curvature, axial length, etc.).Through the establishment of children’s refractive development archives, the doctor can understand the child’s eye development at any time, and timely analysis of the child is the possibility of suffering from myopia, need not need to be corrected in advance and use what kind of method correction, myopia risk stifle in the “cradle”.In addition, children in the establish of refractive archives, the doctor in addition to the optometry on children, also to the child’s eye, the lens and fundus examination, in order to determine whether a child has a high hyperopia, astigmatism and amblyopia, congenital cataract, congenital glaucoma or other fundus lesions, and provide scientific basis for subsequent interventions,It is equivalent to a full physical examination of a child’s eyes every once in a while.If the child is already nearsighted, She suggests parents get a orthokeratology lens for their child.Orthokeratology lens, also known as OK lens, is a rigid gas permeable contact lens (RGPCL) with a series of specially designed geometric shapes that are against the front surface of the cornea. The central area of the lens is flat and the central area is steep to reshape the cornea.Flat to appear central corneal radian within a certain range, and change rules of the samples, to temporarily reduce myopia diopter, children go to bed at night wearing corneal shape lens and can have more than 1.0 the naked eye vision during the day, not only using method, simple, and can let the children get rid of psychological problem because of myopia, let the children to grow better and more healthy.
