Why does the child get myopia easily? Parents should pay attention!

Abstract: from the age of 3 to 6, a comprehensive optometry is performed once a year and a refractive development file is established. The refractive development file is to make a refractive development evaluation for the child’s eyes to see if the child has myopia, hyperopia and astigmatism. According to a data from

, the incidence rate of myopia at 6-8 years old is 25%. The incidence rate of myopia at 9-10 years old was 36%. The incidence rate of myopia at 11-12 years old reached 54%, 13-15 years old, junior high school students, and myopia incidence rate was 69%.

listen to experts say how

eye experts remind: beginning in grade 4, the incidence rate of myopia among children and adolescents has increased year by year, and the incidence rate of myopia has risen sharply in 5 and 6 grades with the beginning of growth and development. Until the junior middle school stage, it has reached a peak of about 70%.

what are the reasons for children’s myopia?

  1. Genetic factors:

parents are children with high myopia, and the risk of myopia is higher than that of ordinary children. If both husband and wife are highly myopic, the probability of children’s myopia is as high as 85%.

  2. Environmental factors:


lack natural light exposure, reading in places where the light is too bright, too dark, glare and reflective, reading in a bumpy environment, and using eyes in an inappropriate environment.

  3. Behavioral factors:


too little outdoor sports, too much close eye use, long-time reading and playing with mobile phones, incorrect writing posture, less sleep time and other behaviors will increase the risk of myopia.

experts say you should do these

1 Increasing outdoor exercise time


research shows that increasing outdoor activities can effectively reduce the incidence rate of myopia. Therefore, for children who want to prevent myopia, the outdoor activity time is at least 2 hours, and 3 hours is better.

  2. Develop good eye habits


pay attention to the correct posture when reading and writing. Don’t read or use your mobile phone when walking or riding. Don’t use your eyes for a long time and rest for 10 minutes every 50 minutes or so. Ensure adequate sleep time.

  3. Establish the archives of refractive development


experts suggest that comprehensive optometry should be done once a year from the age of 3 to 6, and the archives of refractive development should be established. The refractive development file is to make a refractive development evaluation for the child’s eyes to see if the child has myopia, hyperopia and astigmatism. Children before the age of six or seven are low-grade hyperopia, and their refractive state will change with the development of the eyeball, so our common myopia can be predicted in advance. In order to understand the refractive changes of children in detail, find abnormal refractive development in time, take children for refractive examination regularly, and establish perfect refractive development files.

if the child has myopia, the correct way is to choose to go to a professional eye hospital for medical optometry and glasses. Please remember, do not step on the following mined areas:

the first time a child is equipped with glasses (under the age of 15) without mydriasis optometry

when a child has suspected myopia for the first time, he should take the child to an eye hospital for mydriasis optometry. First, distinguish whether the child is true myopia or false myopia, and second, accurately detect the degree of myopia of the child. If it is pseudomyopia, there is no need to wear glasses after the intervention of doctors and reasonable rest. Moreover, because children’s eye adjustment is very strong and do not mydriasis optometry, glasses may often be overcorrected or undercorrected. After


myopia, some parents will choose the computer optometry in the glasses shop at the door of the community. Unexpectedly, this may make myopia “fake and come true”, and the degree of myopia may not be accurate. Ordinary optical shops have no right to mydriasis.


minefields need no ophthalmic examination. Some parents believe that children’s poor eyesight is myopia and do not need to go to the hospital to check their eyes. Poor eyesight is equivalent to glasses. This idea is wrong. Children’s strabismus, amblyopia and congenital cataract may cause vision loss. There are many reasons for children’s vision decline in


. Some children find that the above eye diseases are caused when they go to the hospital for examination. The earlier the treatment of children’s strabismus, amblyopia and cataract is, the better. When they are equipped with glasses in the eye hospital, they must have eye examination first. If they are equipped with glasses at will because they are not checked, they miss the best opportunity for treatment of eye diseases, Many parents regret it.


minefields don’t need regular review after they are equipped with glasses. After


are equipped with glasses, don’t you care? This is wrong! 3 to 12 years old is the sensitive period of visual development. Teenagers’ myopia increases faster than adults, and glasses, like clothes, will become inappropriate with age. Wearing inappropriate glasses for a long time is harmful to children’s eye development. At this time, regular review is particularly important.

for teenagers and children who have myopia, ophthalmologists suggest that they should be examined at least once a year.
