Abstract: the high incidence age of children’s myopia is 8-14 years old, and there will be some signs of myopia in the early stage. If parents carefully observe their children’s performance in learning and daily life during this period, it may be an early sign of myopia.
there are 1.6 billion people with myopia in the world, and 600 million in China, accounting for 1 / 3 of the world. The data show that myopia has become the main cause of visual impairment, and its prevalence rate continues to rise, which is expected to reach 2.5 billion people in 2020. According to statistics, almost all children with high myopia have a pair of “careless” parents behind them. Some parents even think that children’s myopia is pseudomyopia, or give their children a pair of glasses at will. Once a child’s myopia rises to five or six Baidu, he often regrets.
what are the early signs of myopia in children? According to experts from
, the age group with high incidence of myopia is 8-14 years old, and there will be some signs of myopia in the early stage. If parents carefully observe their children’s performance in learning and daily life during this period, it may be an early sign of myopia.
1. Often squint when looking at objects
myopic patients often squint when looking at things, because the eyelids can block part of the pupils when squinting, which can reduce the scattering of light, so as to temporarily improve and improve vision. Therefore, when your child often squints at objects, it should be considered that he may have early myopia.
2. Frequent blinking
frequent blinking can alleviate myopia and enhance vision to a certain extent. Therefore, when your child has the symptoms of frequent blinking, you should consider whether he has early myopia.
3. Often rub eyes
when some children can’t see objects clearly because of myopia, they often rub their eyes with their hands in order to see objects better. Therefore, when you find that your child often rubs his eyes, you should take him to the hospital to check his eyesight in time.
4. Often look at objects with their heads askew
some children with early myopia often look at objects with their heads askew. This is because looking at objects askew can reduce the impact of scattered light on their vision. Therefore, when you find that your child often looks at objects with his head tilted, be sure to take him to the hospital to check his eyesight, and correct his wrong posture when looking at objects, so as not to make him form the habit of looking at objects with his head tilted.
5. When looking at things, your eyes are close to things.
when your child looks at objects, he always sticks close to objects. When reading and writing, he often complains that the light in the room is too dark, we should consider that your child may suffer from myopia.
when your child sees acquaintances who often don’t say hello, acts in the dark, often trips or bruises by things, or often can’t see the handwriting on the blackboard, he should also consider whether your child has myopia.
optometrists specially remind you that scientific optometry is particularly important for children, and formal medical optometry should have 5 procedures.
step 1: check the eye health.
includes slit lamp examination, eye position examination, eye muscle examination, fundus examination, etc. slit lamp examination can exclude eye diseases such as keratitis, trichiasis and cataract, and fundus examination can exclude glaucoma and fundus diseases, which may cause vision loss. Eye position and eye muscle examination can show whether the child has significant strabismus, implicit strabismus, etc.
the second step is to dilate the pupil
for the first time, the pupil should be dilated regardless of age. The doctor will choose different ways of dilating the pupil according to the specific situation of the child, In other words, it is often called rapid mydriasis and slow mydriasis (atropine and topicamide). The third step of
is objective optometry. The accuracy of
retinoscopy is significantly higher than computer optometry, especially for children.
the fourth step is audition
According to the child’s specific situation and tolerance, Through adjustment, the clarity of binocular vision is basically the same (children with strabismus and amblyopia should be analyzed separately), and it is necessary to refer to various factors such as eye position, eye muscle, adjustment and collection before mydriasis, and finally give the glasses prescription.
step 5 is to synthesize the above four steps for glasses
Optometry is accurate, and the grinding process of glasses can not be careless. Even if the doctor’s optometry sheet is correct and the glasses are not matched accurately, the previous efforts will be wasted. Only by grasping these five steps can the glasses be more suitable and comfortable.
under normal circumstances, children wearing appropriate glasses should not have discomfort symptoms such as dizziness, headache and eye pain. Children with pseudomyopia should have mydriasis to avoid eye fatigue and adjust their eye habits; Children with true myopia need to go through formal medical optometry and wear glasses. Wearing glasses, vision still drops rapidly. The reason may be that the glasses are inappropriate, etc.
Children should watch TV and surf the Internet in moderation. They should rest their eyes for about half an hour to an hour, do more outdoor sports and avoid excessive eye use. In addition, children’s eyes and body are developing rapidly. At this stage, we should pay attention to balanced nutrition, eat less sweets and fast food, and eat more coarse grains, vegetables, fruits and other foods beneficial to eye health.
