Abstract: the vast majority of myopia patients are teenagers, but there are several adults from time to time, including the case of “the best eyesight before the age of 18 and myopia after the age of 18”; There are also adult myopia degrees that not only do not brake, but deepen year by year and progress rapidly., Myopia, to put it bluntly, is that in the process of eye development, due to excessive use of eyes and poor eye habits, the eye axis gradually elongates. After the light passes through the pupil, the imaging can not accurately fall on the retina, and we can no longer see clearly. At this time, the doctor will tell you that you are short-sighted., In the past, we all thought myopia was a child’s problem. Parents are like enemies when they hear about their children’s myopia, but when their children reach the age of 18, even if the “dust has settled”, the degree of myopia has basically not changed since then. But now, this idea really doesn’t work., Compared with children, the visual acuity of adults should be more stable and will not easily develop into myopia, but now it is found that adult myopia is coming., Adults may also be myopic. The vast majority of myopic patients are teenagers, but there are several adults from time to time, among which there are cases of “excellent eyesight before the age of 18 and myopia after the age of 18”; There are also adult myopia degrees that not only do not brake, but deepen year by year and progress rapidly., Myopia was originally a juvenile disease. Why has it become an adult disease now? The reason is not hard to guess: it’s all the trouble caused by close work., The reason why the incidence of myopia among teenagers is high is that they use more eyes for reading and do close homework during the study period; Second, they are also in the process of growth and development, and their eyeballs are easy to be affected. When the two are added, the axis of the eye lengthens, and myopia comes., In adults, the development of eyeballs has been basically perfect. Therefore, in the traditional concept, myopia has nothing to do with adults. Those who are not short-sighted will rest assured, and those who are short-sighted will not make great progress. But in recent years, ophthalmologists have found that even if the adult’s eyeballs have been fully developed, they can’t stand the “destruction” of using the eyes for a long time and close distance.,
myopia, to put it bluntly, is that in the process of eye development, because of excessive use of eyes and poor eye habits, the eye axis gradually elongates, but the light can not accurately fall on the retina after passing through the pupil, so we can no longer see clearly. At this time, the doctor will tell you that you are short-sighted.
in the past, we all thought myopia was a child’s problem. Parents are like enemies when they hear about their children’s myopia, but when their children reach the age of 18, even if the “dust has settled”, the degree of myopia has basically not changed since then. But now, this idea really doesn’t work. Compared with children,
and
, the visual acuity of adults should be more stable and will not easily develop into myopia, but now it is found that adult myopia is coming.
and
may also be myopic in adulthood. The vast majority of
and
myopic patients are teenagers, but there are several adults from time to time, among which there are cases of “excellent vision before the age of 18 and myopia after the age of 18”; There are also adult myopia degrees that not only do not brake, but deepen and progress rapidly every year.
myopia was originally a juvenile disease. Why has it become an adult disease now? The reason is not hard to guess: it’s all the trouble caused by close work.
and
teenagers have a high incidence of myopia. First, they use more eyes for reading and do close homework during their study period; Second, they are also in the process of growth and development, and their eyeballs are easy to be affected. When the two are added, the eye axis is elongated, and myopia comes.
and
in adults, the development of eyeballs has been basically perfect. Therefore, in the traditional concept, myopia has nothing to do with adults. Those who are not myopia will rest assured, and those who are myopia will not make great progress. But these years, ophthalmologists have found that even if the adult’s eyeballs have been well developed, they can’t stand the “destruction” of using the eyes for a long time and close distance.
eight symptoms of myopia
symptom 1: squint
when distant targets can’t be seen clearly, children often squint to make up for it, because when squinting, the eyelids can block part of the pupils, reduce diffuse light and reduce the influence of astigmatism, so as to temporarily improve and improve visual acuity. Symptom 2 of
and
: rub your eyes. When you can’t see the target clearly, you often rub your eyes with your hands in an attempt to see more clearly.
symptom 3: blink
frequent blinking can alleviate myopia and increase visual acuity in a certain procedure. When many people shed tears, they will see things more clearly. Symptom 4 of
and
: crooked head
and
often happen when crooked head watches TV. It is also because when crooked head, it can reduce the interference and influence of some scattered light, and some children will even form the habit of crooked head.
symptom 5: error
the distant target is not clear, and they don’t say hello to acquaintances. You will copy wrong questions in the exam. You can trip or bruise by something when you act in the dark. Others show a decline in academic performance and often have to borrow other people’s notes to copy, etc. Symptom 6 of
and
: get close to
and
often show when watching TV, get close to the TV as much as possible, and read and write. Lie close and low.
symptom 7: pulling eyes
when a few children can’t see the distant target clearly, they often use their hands in the outer corners of their eyes and pull the skin of the corners of their eyes outward to achieve the same effect as squinting their heads and squinting their eyes. Symptom 8 of
and
: some myopia children with strabismus
and
have exotropia. When one eye looks ahead, the other eye tends to the outside. Therefore, when you find an oblique eye, you must check your eyesight first.
